Lever Release Actuator Description The manual lever release actuator provides a manual means of actuating cylinder valves and selector valves. This can be accomplished by direct manual actuation of its pull lever or cable actuation when used in conjunction with a remote manual pull station. When used with a remote manual pull station, the pull station must contain the components necessary to meet the actuator lever traveling requirements of 7 in. (178 mm). The actuator is shipped with ring pin and chain attached. If the ring pin is not required, it must be removed. Failure to remove the ring pin/chain assembly will prevent system actuation if a remote cable pull actuation system is employed and the ring pin is accidentally installed in the actuator.

Remote Cable Pull Equalizer Description The remote cable pull equalizer is used in systems where manual actuation of the cylinder valve and operation of a selector valve must be accomplished at the same time. The pull equalizer is mounted in the remote pull station cable line. By pulling the remote pull box, the cable attached to the pull equalizer will pull the internal cable clamp in the pull equalizer which in turn will pull the cables attached to the cylinder valve and selector valve, causing them to operate. Two styles of pull equalizers are available. Part No. 842791 is 13 3/4 in. (34.9 cm) long and Part No. 843168 is 20 3/4 in. (52.7 cm). Only the longest equalizer, Part No. 843168, can be used for valves utilizing sectors. The inlet and outlet connections are threaded for 3/8 in. pipe. If 1/2 in. EMT conduit connections are required, adaptor Part No. 845780 is available.

Check Valves Description Check valves are used in main/reserve and selector valve systems. On main/reserve systems, the check valve prevents pressurization of the reserve system manifold by blocking the flow of INERGEN ® agent from the main system to the reserve system. The check valve allows gas flow from the reserve (if actuated) to through into the distribution piping. On selector valve systems, check valves separate the actuation of smaller system(s) from the largest ones. The check valves are available in sizes from 1/2 in. through 3 in.

PRODUCT NAME

INERGEN agent is a mixture of three naturally occurring gases: nitrogen, argon, and carbon dioxide. As INERGEN agent is derived from gases present in the earth’s atmosphere, it exhibits no ozone depleting potential, does not contribute to global warming, nor does it contribute unique chemical species with extended atmospheric lifetimes. Because INERGEN agent is composed of atmospheric gases, it does not pose the problems of toxicity associated with the chemically derived Halon alternative agents. PRODUCT DESCRIPTION The INERGEN Fire Suppression System, manufactured by Ansul, is an engineered system utilizing a fixed nozzle agent distribution network. The system is designed and installed in accordance with the National Fire Protection Association (NFPA) Standard 2001, ‘‘Clean Agent Fire Extinguishing Systems.’’ When properly designed, the INERGEN system will extinguish surface burning fire in Class A, B, and C hazards by lowering the oxygen content below the level that s combustion. INERGEN agent has also been tested by FMRC for inerting capabilities. Those tests have shown that INERGEN agent, at design concentrations between 40% and 50%, has successfully inerted mixtures of propane/air, and methane/air. The system can be actuated by detection and control equipment for automatic system operation along with providing local and remote manual operation as needed. Accessories are used to provide alarms, ventilation control, door closures, or other auxiliary shutdown or functions. When INERGEN agent is discharged into a room, it introduces the proper mixture of gases that will allow a person to breathe in a reduced oxygen atmosphere. A system installation and maintenance manual is available containing information on system components and procedures concerning design, operation, inspection, maintenance, and recharge. The system is installed and serviced by authorized distributors that are trained by the manufacturer. Basic Use – The INERGEN system is particularly useful for suppressing fires in hazards where an electrically non-conductive medium is essential or desirable; where clean-up of other agents present a problem; or where the

• Computer rooms • Subfloors • Tape storage • Telecommunication/Switchgear • Vaults • Process equipment • All normally occupied or unoccupied electronic areas where equipment is either very sensitive or irreplaceable Composition and Materials – The basic system consists of extinguishing agent stored in high strength alloy steel cylinders. Various types of actuators, either manual or automatic, are available for release of the agent into the hazard area. The agent is distributed and discharged into the hazard area through a network of piping and nozzles. Each nozzle is drilled with a fixed orifice designed to deliver a uniform discharge to the protected area. On large hazards, where three or more cylinders are required, a screwed or welded pipe manifold assembly is employed. The cylinder(s) is connected to the distribution piping or the manifold by means of a flexible discharge bend and check valve assembly. Additional equipment includes – Control s, releasing devices, remote manual pull stations, corner pulleys, door closures, pressure trips, bells and alarms, and pneumatic switches. All or some are required when deg a total system. INERGEN Agent – INERGEN agent is a mixture of three inerting (oxygen diluting) gases: 52% nitrogen, 40% argon, and 8% carbon dioxide. INERGEN gas extinguishes fire by lowering the oxygen content below the level that s combustion. When INERGEN agent is discharged into a room, it introduces the proper mixture of gases that still allow a person to breathe in a reduced oxygen atmosphere. It actually enhances the body’s ability to assimilate oxygen. The normal atmosphere in a room contains 21% oxygen and less than 1% carbon dioxide. If the oxygen content is reduced below 15%, most ordinary combustibles will cease to burn. INERGEN agent will reduce the oxygen content to approximately 12.5% while increasing the carbon dioxide content to about 3%. The increase in the carbon dioxide content increases a person’s respiration rate and the body’s ability to absorb oxygen. Simply stated, the human body is stimulated by the carbon dioxide to breathe more deeply and rapidly to compensate for the lower oxygen content of the atmosphere.

Cylinder Assembly – The cylinder assembly is of steel construction with a red standard finish. One size is available. Each cylinder is equipped with a pressure seat-type valve equipped with gauge. The valve is constructed of forged brass and is attached to the cylinder providing a leak tight seal. The valve also includes a safety pressure relief device which provides relief at 4000-4480 psi (276-309 bar) per CGA test method. Cylinder charging pressure is 2900 psi at 70 °F (200 bar at 21 °C). The cylinders are shipped with a maintenance record card and shipping cap attached. The cap is attached to the threaded collar on the neck of each cylinder to protect the valve while in transit. The cylinder serial number and date of manufacture are stamped near the neck of each cylinder. Electric Actuator – Electric actuation of an agent cylinder is accomplished by an electric actuator interfaced through an AUTOPULSE® Control System. This actuator can be used in hazardous environments where the ambient temperature range is between 32 °F and 130 °F (0 °C and 54 °C). In auxiliary or override applications, a manual lever actuator can be installed on top of the actuator. Manual or Pneumatic Actuators – Three types of manual actuators are available for lever actuation on the cylinder valve. Manual actuation is accomplished by pulling the hand lever on the actuator. Detection System – The AUTOPULSE Control System is used where an automatic electronic control system is required to actuate the INERGEN system. This control system is used to control a single fixed fire suppression or alarm system based on inputs received from fire detection devices. The detection circuits can be configured using cross, counting, independent or priority-zone (counting) concepts. The control system has been tested to the applicable FCC Rules and Regulations for Class A Computing devices.

Nozzles – Nozzles are designed to direct the discharge of INERGEN agent using the stored pressure from the cylinders. Nozzles are available in either 360° or 180° discharge patterns. The system design specifies the nozzle and orifice size to be used for proper flow rate and distribution pattern. The nozzle selection depends on the hazard and location to be protected. Pressure Reducer – The pressure reducer is required in the distribution piping to restrict the flow of INERGEN agent, thus reducing the agent pressure down stream of the reducer. The pressure reducer contains a stainless steel orifice plate which is drilled to the specific size hole required based on the hydraulic calculation. The orifice plate provides readily visible orifice identification. The pressure reducer is available in nine sizes: 1/2 in., 3/4 in., 1 in., 1 1/4 in., 1 1/2 in., 2 in., 2 1/2 in., 3 in., and 4 in. NPT.

person to breathe in a reduced oxygen atmosphere. It actually enhances the body’s ability to assimilate oxygen. The normal atmosphere in a room contains approximately 21% oxygen and less than 1% carbon dioxide. If the oxygen content is reduced below 15%, most ordinary combustibles will not burn. INERGEN agent will reduce the oxygen content to approximately 12.5% while increasing the carbon dioxide content to about 3%. The increase in the carbon dioxide content increases a person’s respiration rate and the body’s ability to absorb oxygen. Simply stated, the human body is stimulated by the carbon dioxide to breathe more deeply and rapidly to compensate for the lower oxygen content of the atmosphere.

APPLICATION INERGEN® extinguishing agent used in Ansul engineered systems is particularly useful for hazards where an electrical, nonconductive medium is essential or desirable; where clean-up of other agents presents a problem; where hazard obstructions require the use of a gaseous agent; or where the hazard is normally occupied and requires a non-toxic agent. The following are typical hazards protected by INERGEN systems: • Computer rooms • Subfloors

• Process equipment • All normally occupied or unoccupied areas where electronic equipment is either very sensitive or irreplaceable ENVIRONMENTAL IMPACT INERGEN agent is a mixture of three naturally occurring gases: nitrogen, argon and carbon dioxide. As INERGEN agent is derived from gases present in the earth’s atmosphere, it exhibits no ozone depleting potential, does not contribute to global warming, nor does it contribute unique chemical species with extended atmospheric lifetimes. Because INERGEN agent is composed of atmospheric gases, it does not pose the problems of toxicity associated with the chemically derived Halon alternative agents. DESCRIPTION INERGEN agent is a plentiful, non-corrosive gas that does not combustion nor react with most substances. INERGEN agent contains only naturally-occurring gases which have no impact on the ozone or the environment in general. INERGEN agent is a mixture of three inerting (oxygen diluting) gases: 52% nitrogen, 40% argon, and 8% carbon dioxide. INERGEN agent extinguishes fire by lowering the oxygen content below the level that s combustion. When INERGEN agent is discharged into a room, it introduces the proper mixture of gases that still allow a

General Information INERGEN® AGENT INERGEN is a plentiful, non-corrosive gas that does not combustion nor react with most substances. INERGEN agent contains only naturally-occurring gases which have no impact on the ozone or the environment in general. INERGEN agent is a mixture of three inerting (oxygen diluting) gases: 52% nitrogen, 40% argon, and 8% carbon dioxide (see MSDS in Section II). INERGEN extinguishes fire by lowering the oxygen content below the level that s combustion. When INERGEN agent is discharged into a room, it introduces the proper mixture of gases that allow a person to breathe in a reduced oxygen atmosphere. It actually enhances the body’s ability to accumulate oxygen. The normal atmosphere in a room contains approximately 21% oxygen and less than 1% carbon dioxide. If the oxygen content is reduced below 15%, most ordinary combustibles will not burn. INERGEN agent will reduce the oxygen content to approximately 12.5% while increasing the carbon dioxide content to about approximately 3%. The increase in the carbon dioxide content increases a person’s respiration rate and the body’s ability to absorb oxygen. Simply stated, the human body is stimulated by the carbon dioxide to breathe more deeply and rapidly to compensate for the lower oxygen content of the atmosphere.

PERSONAL SAFETY Proper INERGEN system design requires that the design concentrations fall within a design window that limits the upper and lower requirements of both oxygen and carbon dioxide. INERGEN agent has acceptable toxicity for use in occupied spaces when used as specified in the United States Environmental Protection Agency (EPA) proposed Significant New Alternative Policy (SNAP) program rules and NFPA 2001, “Clean Agent Fire Extinguishing Systems.” When design concentrations are in this window, no adverse affects will take place on the human respiratory system. Any exposure outside of these limits requires the use of self-contained breathing apparatus. Respirators will not function in oxygen deficient atmospheres. Because of the decomposed products of combustion generated during an actual fire and extinguishment, it is a good safety rule to ventilate the hazard for at least 15 minutes before entering or if entry is required sooner, wear an approved self-contained breathing apparatus. Refer to NFPA 2001, 2000 edition, Paragraph 1-6.1.3, “Inert Gas Clean Agents,” for detailed exposure conditions. HMIS 1-0-0/very cold discharge. Contents under high pressure.

Avoid direct of the cold, high pressure discharge and avoid direct inhalation of undiluted gas.

WARNING AVOID EXPOSURE TO VAPORS, FUMES, AND PRODUCTS OF COMBUSTION. TYPE OF SYSTEM Total flooding is the approved type of system available. A total flooding system normally consists of a fixed supply of INERGEN connected to piping with nozzles to direct the agent into an enclosed hazard space. In a total flooding system, the enclosure around the hazard must be tight enough to hold the required percentage of INERGEN concentration for a period of time to extinguish the fire.

TYPES OF ACTUATION There are three basic types of actuation for the INERGEN systems: pneumatic, mechanical, and electrical. Electrical Automatic electrical actuation of the cylinder valve, through an approved control , can be accomplished by using an HF actuator for the CV-98 valve. The actuator is energized by an electric signal from the detection/control . When using the electric actuator, pneumatic or mechanical actuating devices can also be attached as a secondary means of actuation. When using electric actuation, a means of manual release shall also be provided. Mechanical Mechanical actuation is accomplished by a lever actuator mounted on top of the cylinder valve or other actuators. By rotating the lever on the actuator, either locally or from a remote pull station, the cylinder valve can be opened, allowing the INERGEN to discharge through the piping and nozzles.

SECTION III UL EX-4510 REV. 1

7-15-02

Page 3-2

General Information TYPES OF ACTUATION (Continued) Pneumatic Pneumatic actuation utilizes gas pressure from a cartridge located in a releasing device such as an ANSUL AUTOMAN II-C release. The gas pressure forces the piston of the pneumatic actuator down, which in turn forces the cylinder valve to open, releasing INERGEN agent from the cylinder, through the piping and out the nozzles. On a CV-98 valve, a 1/4 in. actuation line is attached to the 1/8 in. port on the side of the valve. Pneumatic pressure, from an ANSUL AUTOMAN II-C or another pilot cylinder, opens the valve through this port.

INERGEN FLOW The flow of INERGEN in the system discharge piping is a compressible flow. The agent is a compressed gas, the temperature and density of which changes as the pressure in the pipe decreases. The flow calculation is based on classical energy conservation considerations. For simple systems, an assumption of adiabatic expansion of the agent is sufficient. The ANSUL flow calculation program, however, s for heat transfer from the pipe into the flowing agent. The consideration of heat input to the agent permits a greater degree of flexibility in system design.

compensated heat detectors. NOTE: When deg the system, make certain the type of detector used is appropriate for the type of hazard so proper response is attained in a fire situation. When a detector senses a fire, a signal is sent to the control . The in turn sends an electrical signal to the solenoid actuator located on the pilot cylinder valve. The actuator opens the cylinder valve releasing the INERGEN agent into the manifold. The pressure in the manifold then causes the slave valves to open and discharge INERGEN into the piping network and out the nozzles. Electric Releasing Device The ANSUL AUTOMAN II-C electric releasing device uses approved thermal detectors and actuates the INERGEN cylinders pneumatically, utilizing high pressure nitrogen to operate the cylinder valve.

SYSTEM LIMITATIONS Design Limitations • Unbalanced systems (protecting multiple hazards) operating temperature range: 60° to 80° F (15° to 27 °C) • Unbalanced systems (protecting single hazards) operating temperature range: 32° to 130 °F (0° to 543 °C) • Hazard temperature: –40° to 200 °F (–40° to 93 °C)

The ANSUL “INERGEN” system uses an orifice at the outlet of the storage cylinder manifold to produce a substantial pressure drop before the INERGEN enters the main distribution pipe network. The prediction of conditions immediately after the orifice is based both on classical theory and empirical data taken by ANSUL.

• Spare cylinder storage temperature: 0° to 130 °F (–17° to 54 °C)

Discharge nozzles control the amount of INERGEN which flows into various portions of the protected space. The flow through the discharge nozzles is predicted by classical theory enhanced by empirical data developed by ANSUL.

• Maximum nozzle height above floor level for a single row of nozzles is 20 ft. (6.1 m). For ceiling heights over 20 ft. (6.1 m), an additional row of nozzles is required.

TYPES OF DETECTION There are two approved types of detection available for the INERGEN system: electronic control and electric releasing device.

• Manifolding: All cylinders on the same manifold must be the same size

Electronic Control Electric actuation of the INERGEN system is obtained through the use of electronic control systems which monitor and control various system functions. All detection equipment must be installed according to NFPA 70 and NFPA 72. Detection devices available are: ionization smoke detectors, photoelectric smoke detectors, flame detectors, and rate

Flow Calculation Limitations • Minimum Nozzle Pressure 375 psi (2586 kPa) Pressure: • Maximum Pipe Volume vs. 56% Cylinder Volume: • For unbalanced systems, UL/ULC ratio of nozzle orifice diameter to pipe diameter shall be a minimum of 11.5% to a maximum of 70%.

• For unbalanced systems, UL/ULC ratio of pressure reducer orifice to inlet pipe diameter shall be a minimum of 13% to a maximum of 55%. • In an unbalanced piping system, the time lag in reaching peak pressure at the various nozzles in the system may vary. If the variation is beyond certain programmed limits, an error message is generated indicating that the time to reach pressure at one or more nozzles is too long. This condition may result if the length of pipe leading to a nozzle is extremely long compared to the length of pipe leading to one or more other nozzles in the system. • For unbalanced systems, the INERGEN Designer 5.0.1 Computer Design Program is the only calculation method to be used with Ansul Engineered INERGEN systems. • The INERGEN Designer 5.0.1 Computer Design Program is designed for a +70 °F (+21 °C) cylinder operating/ storage temperature. Therefore, the cylinder operating/ storage temperature must be in the range of +60 °F to +80 °F (+15.5 °C to 26.7 °C) for a single unbalanced system protecting two or more separate hazards. If the cylinder operating/storage temperature is outside this range, an insufficient or excessive quantity of agent may be discharged from one or more discharge nozzles. If cylinders cannot be stored within this range, then each hazard must be protected with its own individual system. • Maximum and minimum flow rates per table. (NOTE: Table entries are rounded to the nearest whole numbers. Computer calculation uses same data in equation form – therefore there may be slight (1 scfm or less) differences in the minimum and maximum values on the computer printout.) This table is for general use only. It can be used for evaluation of a completed flow calculation. • The calculation method has been designed for specific types of fittings, pipe, and pipe inside diameter. When these limitations are not maintained, there is a risk that the system will not supply the required quantity of extinguishing agent.

Planning Planning for design and installation for an INERGEN system should start when the customer is first ed in regards to protecting his hazard with INERGEN. Most of the information gathered for the design of a system is collected during the first meeting with the customer. The information gathered at this point will determine the ease or difficulty of the rest of the project. One of the key elements for fire protection is to correctly define the hazard and conduct a complete survey to determine if the system will properly protect the hazard. Coordination with all parties involved in the project will further improve the flow of the overall project.

Hazard Information:

A thorough hazard analysis is required to determine the protection required. It is important to cover each element and accurately record the information. This information will be used to determine the size and location of the INERGEN system required and also to determine at a later date if any changes were made to the hazard after the system was installed. Information necessary for design of an INERGEN system is listed in the following paragraphs.

• Indicate the quantity and locations of all exits from the hazard on the sketches.

A Proposal Information Form, F-9355, is included in the appendix of this manual to assist in a hazard analysis of the protected areas.

• Identify the hazards normal, maximum, and minimum ambient temperatures.

Initial General Information:

• Identify any openings, or potential openings in the hazard enclosure that may cause loss of agent during or after discharge.

• Are Specifications available? If so obtain a copy. • Who is the “Authority Having Jurisdiction”? the owner? • Will the system need to be approved by any other regulatory or insurance agencies? • Will any special requirements apply to the system design or installation?

• Secure the general arrangement drawings of the areas to be protected. • If the general arrangement drawings do not include the following information then you must obtain it. • Record all dimensions for the hazard areas such as length, width, ceiling height, angles of corners if not 90 degrees, etc. • Draw a sketch including plan and elevation views of the hazard area if drawings are not available.

• Record all dimensions for any structural objects such as beams or columns, built in cabinets, ducts, etc. which may allow a reduction of the hazard volume. • Identify anything unique about the hazard that would affect system design or installation.

• Will the hazard area be normally occupied?

• If possible, determine the maximum strength of the weakest wall, floor, or ceiling. This information will be used to calculate venting requirements. If this information is not available, a conservative number will be used to calculate the required free venting area. This conservative number will probably increase the size of venting required.

SECTION IV UL EX-4510 REV. 1

7-15-02

Page 4-2

Planning INERGEN Supply Requirements:

Piping and Wiring Information:

• Will the cylinders be located in a dedicated space? If so, record dimensions of that space.

• Determine the cylinder location.

• If the system is unbalanced, is the operating temperature range within 60° to 80° F (15° to 27° C)?

• Indicate any obstructions to the piping or wiring runs.

• Determine if the floor will the cylinders and bracketing. Assume 275 lbs/ft2 for this requirement. • Will the cylinder bracketing be secured to a wall? If so, is the wall strong enough to it and the cylinders? • Will Uprights be required for the bracketing? • Will Manifold s be required to the manifold? • Will a reserve supply of agent be required? If so will it need to be connected to the manifold? • Will a discharge test be required? Actuation and Alarm Requirements: • Will the system be actuated automatically as well as manually? • What type of manual actuation (cable pull or pneumatic) is required? • Will multiple areas be protected by a single system? If so, will the areas be protected separately or simultaneously? • Identify the locations for all Manual Pull Stations. • If automatic detection is a part of the system, provide ceiling details. • What types of alarm devices are required; audible and/or visible? • Where will the system actuation be annunciated? • Does the hazard area require explosion-proof or weatherproof wiring and devices? • What devices need to be shut down or started up? Identify the number of s required.

• Identify preferred supply piping routes. • If the system includes Selector Valves, indicate their location. Ventilation and Leakage Concerns: • Identify any unclosable openings regardless of their size. • Advise the customer of the possible need to seal these openings to prevent agent loss. • Advise the customer of the possible need to provide pressure venting during discharge. • Determine the route venting will need to take to reach outside atmosphere. Consult the INERGEN Pressure Relief Venting Guide, Part No. 422793, for definition of outside atmosphere. • Will the venting route involve venting through other enclosures or ducts? If so, provide details about the rooms or duct routing information. • If the venting will be through other enclosures, will they be protected also? If so, will they be protected separately or simultaneously? • Will dampers be required for Inlet or Exhaust ducts? If so, how will they be operated, electrically or pneumatically?

Design After completing the hazard analysis sub-section in Section IV Planning, proceed with the following elements to work up a complete design and bill of materials. An example is included with each step to help the reader to understand the procedure. The example uses a computer room and subfloor as shown below.

APPLICATION METHOD Total flooding is the only approved application method for INERGEN systems. INERGEN agent is stored and discharged as a gas; it does not create a liquid stream, therefore, local application of INERGEN agent is not possible because the flow of gas cannot be accurately predicted once it exits the nozzles.

If the irregular shape will affect distribution of agent, it may be best to calculate sections of the hazard as separate areas and include nozzles for each of these areas. If the ceiling height exceeds the maximum allowable ceiling height as defined in the General Information Section of this manual, multiple levels of nozzles must be designed into the system. In this case, it is usually beneficial to treat each level as a separate protected area so that proper agent distribution is achieved. Complete this step for each area protected by the system. Example: • Computer Room • 20 ft. 0 in. L x 13 ft. 0 in. W = 260 ft2, x 10 ft. 0 in. H = 2,600 ft3 • Subfloor • 20 ft. 0 in. L x 13 ft. 0 in. W = 260 ft2, x 1 ft. 0 in. H = 260 ft3 STEP NO. 2 – Determine volume of solid, permanent structures, or equipment The volume of solid objects in each hazard area that are not removable can be deducted from the volume of the hazard. This volume may include columns, beams, cut-out room sections, closets that will always be closed, ducts that completely through the area without any openings, and any other large, permanently fixed objects that cannot be removed from the hazard enclosure.

Total Flooding The following steps must be followed, in the order they are presented, to properly design an INERGEN total flooding system. A simple design example will be used throughout the steps to help understand each step. Use the Design Calculations Worksheet on Page 5-17 in this section. STEP NO. 1 – Determine hazard volume(s) The first step in the design of an INERGEN system is to calculate the volume of each area to be protected. Multiply the length times the width to determine the area, and then multiply the area times the height to determine the volume for each hazard area. If any area is an odd shape, the designer may need to divide it up into regular shapes that will allow volume calculations, and then total all of the volumes together to determine the actual volume of that area.

Calculate the volume of all such objects and add them together to determine the amount of space to be deducted from the volume. Complete this step for each enclosure protected by the system. Example Computer Room: • Columns: 2 ft. 6 in. L x 2 ft. 0 in. W = 5 ft2, x 10 ft. 0 in. H = 50 ft3 x 2 Columns = 100 ft3 Subfloor: • Columns: 2 ft. 6 in. L x 2 ft. 0 in. W = 5 ft2, x 1 ft. 0 in. H = 5 ft3 x 2 Columns = 10 ft3

Design APPLICATION METHOD (Continued) Total Flooding (Continued) STEP NO. 3 – Calculate Reduced Volume Subtract the volume of solid, permanent objects (Step No. 2) from each of the hazard’s volumes (Step No. 1). The result is considered to be the Reduced Volume for the enclosure. Volume – Solid Object Volume = Reduced Volume Complete this step for each area protected by the system. Example Computer Room: • 2,600 ft3 – 100 ft3 = 2,500 ft3 Subfloor: • 260 ft3 – 10 ft3 = 250 ft3 STEP NO. 4 – Determine minimum design concentration Minimum Design Concentration is defined by NFPA 2001 as the Extinguishing Concentration plus a safety factor, depending on the fuel. Extinguishing Concentration is the agent concentration required to extinguish a test fire. The Minimum Design Concentration for various fuels is shown in the following table: INERGEN Minimum Design Concentrations Class A Surface Fuels

34.2%

Class B Fuels

Heptane 40.7%*

Class C Fuels

34.2%

* Ansul Technical Ser vices Depar tment for Minimum Design Concentrations for other Class B fuels.

Class A, B ( Ansul for types), and C hazards are UL listed for INERGEN systems. Complete this step for each area protected by the system. Design Concentrations are determined by NFPA 2001, 2000 edition, Paragraph 3-4.2 and UL-2127, first edition, Paragraph 59.2(b): INERGEN cupburner value is 31% for commercial grade Heptane Nozzle distribution test concentration = 31.25%

Calculations: Cupburner or fire test concentration x nozzle efficiency factor x safety factor Nozzle efficiency factor = 31.25 ____ = 1.008 31.0 Safety Factor: Class A = 1.2 Class B = 1.3 Class C = Class A For Class A (determine by fire test) – 28.24% x 1.008 x 1.2 = 34.2% For Class B (commercial grade heptane) – 31.25% x 1.3 = 40.7% For Class B (other Class B fuels) – cupburner x 1.008 x 1.3 = design concentration For Class C = Class A For systems with only manual actuation – cupburner or fire test concentration x 1.008 x 1.3 = design concentration STEP NO. 5 – Determine minimum quantity of INERGEN agent required This step is used to determine the minimum amount of INERGEN agent required to protect each hazard area. The amount of agent calculated during this step is the minimum amount of agent that is required to protect the hazard area. The amount of agent in the system must always be at least this much and may be exceeded. Failure to supply at least the amount of agent indicated in this step may prevent the system from suppressing a fire. To determine the minimum quantity of INERGEN agent required, determine the lowest anticipated ambient temperature for the area being protected and determine the design concentration required for the material to be extinguished. Minimum Ambient Temperature is defined as the lowest anticipated temperature in the enclosure during normal conditions and is usually determined by the environmental conditions or the air handling system. This temperature is used in the design because it is the “worst case,” meaning that it will require the highest amount of agent.

Design APPLICATION METHOD (Continued)

Step No. 6 – Adjust Quantity of Agent with Altitude Correction Factor

Total Flooding (Continued) Using these two variables, the INERGEN agent flooding factor can be calculated in either of two ways: First: The formula in NFPA 2001 can be used. X = 2.303

[ ] VS S

Log10

[

]

100 100-C

X = INERGEN agent flooding factor S = 9.8579 + 0.02143 (T) T = minimum anticipated temperature in the protected volume (°F) C = INERGEN concentration, % by volume VS = Specific volume at 70 °F (cu.ft./lb.) = 11.358 cu. ft./lb. NOTE: This calculation includes an allowance for the normal leakage (efflux) from a “tight” enclosure due to agent expansion. The second option for calculating the required quantity of INERGEN agent is to refer to the “Flooding Factor Chart” on Page 5-18 in to determine the correct flooding factor to use. To do this, star t by locating the Minimum Ambient Temperature in the left column, follow this line across until you reach the column for the Minimum Design Concentration needed for the design. The number listed where the temperature line and the concentration column meet is the Flooding Factor to be used. NOTE: If the minimum temperature, the minimum design concentration, or both are not listed, interpolation will be required. Next, to determine the quantity of INERGEN agent, multiply the Reduced Hazard Volume by the Flooding Factor determined from the table. Complete this step for each area protected by the system. NOTICE The actual design concentration of INERGEN agent cannot be less than the concentration selected in Step No. 4. Example Minimum Ambient Temperature = 60 °F. Flooding Factor = 0.427 Computer Room • 2,500 ft3 x 0.427 = 1067.5 ft3 INERGEN Agent Required Subfloor • 250 ft3 x 0.427 = 106.8 ft3 INERGEN Agent Required

It may be necessary at this point to adjust the required initial INERGEN agent quantity for altitude effects. An increase in altitude or pressure causes a gas to expand and occupy more space, which will lead to a higher concentration if the agent quantity is not reduced accordingly. A decrease in altitude will cause the opposite effect, increasing the quantity of agent required. This same effect will apply to increases or decreases in the ambient pressure as could be caused by ventilation systems designed to maintain a positive or negative pressure within the enclosure. To apply the proper adjustment, first look up the altitude or pressure of the hazard on the “Atmospheric Correction Factors Chart” on Page 5-20 in this section. Determine the total INERGEN agent required by multiplying the initial INERGEN quantity by the Altitude Correction Factor. If the altitude is between 3000 ft. below seal level and 3000 ft. above sea level, use of the altitude correction factor is optional. Interpolation of the table may be necessary if the actual altitude or pressure is not listed. Example The hazard altitude is 4000 feet. Referring to the chart on Page 5-20, the altitude correction factor of 4000 ft. is 0.86. Computer Room • 1067.5 ft3 INERGEN Agent x 0.86 = 918.1 ft3 Required Agent Subfloor • 106.8 ft3 INERGEN Agent x 0.86 = 91.8 ft3 Required Agent STEP NO. 7 – Determine the total system INERGEN agent quantity required Add quantities from all areas to determine the minimum total agent quantity required for the entire system. Example 918.1 ft3 + 91.8 ft3 = 1009.9 ft3 Total Agent Required

Page 5-4

Design APPLICATION METHOD (Continued) Total Flooding (Continued) STEP NO. 8 – Determine number of INERGEN cylinders required To determine the number of cylinders required, divide the quantity of INERGEN agent for the entire system by the actual cylinder capacity and then round up to the next whole number. NOTE: The INERGEN cylinder size listed on the Component Sheet is a nominal cylinder size. The quantity entered into the calculation should be the Minimum Fill Quantity in the Cylinder. Refer to the table below for exact quantities. Nominal Cylinder Size _______________ 575 cu. ft.

Actual INERGEN Agent Quantity _____________________ 572 cu. ft.

Example 1009.9 ft3 Total Agent Required ÷ 572 ft3 Cylinder Size = 1.77 = 2 cylinders Required

STEP NO. 10 – Calculate the actual INERGEN agent supplied per area This step is required to split the extra agent evenly between the areas so that they all achieve the same concentration instead of over-concentrating some and under-concentrating others. The calculation is a simple percentage calculation where the area minimum agent quantity is divided by the system minimum agent quantity to determine the percent required for the area in question. Once the percentage is determined, it is applied to the total supplied agent quantity to determine how much of the supplied quantity is to be applied to the area in question. The formula for determining the actual INERGEN agent quantity supplied per area being protected is: (Minimum quantity of agent required for the area in question (from Step No. 6) ÷ the total minimum quantity required for all areas (from Step No. 7)) x the actual quantity of agent supplied (from Step No. 9.) Complete this step for each area protected by the system. Example

STEP NO. 9 – Calculate the actual quantity of INERGEN agent supplied To calculate the Actual Quantity of INERGEN agent supplied, multiply the actual capacity of the INERGEN cylinders chosen by the quantity of cylinders determined in Step No. 8. The result must be higher than the required amount determined in Step No. 7. !

CAUTION

If the INERGEN agent supplied quantity is close to the INERGEN agent required quantity and multiple areas are to be protected the designer may wish to add an additional cylinder to allow enough agent for adjusting of nozzle agent quantities to achieve proper concentrations in all areas. Example 572 ft3 x 2 = 1144 ft3 INERGEN Agent Supplied

Computer Room • (918.1 ft3 Required Agent Per Area ÷ 1009.9 ft3 Total Agent Required) x 1144 lb. Quantity of Agent Supplied = 1040 ft3 Actual Agent Supplied Per Area Subfloor • (91.8 ft3 Required Agent Per Area ÷ 1009.9 ft3 Total Agent Required) x 1144 lb. Quantity of Agent Supplied = 104 ft3 Actual Agent Supplied Per Area STEP NO. 11 – Determine actual INERGEN agent flooding factor This step is necessary to determine the Concentration that the supplied quantity of agent will produce in the protected area as opposed to the Design Concentration. This is required to assure that any of the areas will not be overconcentrated with agent. To determine the actual INERGEN agent flooding factor (this is necessary to complete Step No. 12), divide the ”INERGEN Agent supplied” for each area (from Step No. 10) by the Altitude Correction Factor (from Step 6) and divide the result by the Reduced volume of that hazard area (from Step No. 3). NOTE: If all areas use the same “Minimum Design Concentration” in Step No. 4, the Flooding Factors determined in this step should match for all areas. If this is not the case, a calculation mistake has been made. Review the previous calculations carefully to correct it before proceeding.

Design APPLICATION METHOD (Continued) Total Flooding (Continued) Complete this step for each area protected by the system. Example Computer Room • (1040 ft3 Actual Agent Supplied Per Area ÷ 0.86 Altitude Correction Factor) ÷ 2,500 ft3 Reduced Volume = .484 Actual INERGEN Agent Flooding Factor Subfloor • (104 ft3 Actual Agent Supplied Per Area ÷ 0.86 Altitude Correction Factor) ÷ 250 ft3 Reduced Volume = .484 Actual INERGEN Agent Flooding Factor STEP NO. 12 – Determine the Design Concentration at the Maximum Ambient Temperature for Each Area This step deter mines the Design Concentration of INERGEN agent in each protected area using the Reduced Volume and the supplied quantity of agent for the area at the “Maximum Ambient Temperature.” It is necessary to assure that we do not over-concentrate the area due to the additional agent actually supplied to the area and the increased volume of agent caused by increased temperature. To complete this step, refer to the Flooding Factor Chart on Page 5-11. Star t by locating the Maximum Ambient Temperature in the left column; follow this line across until you find the Flooding Factor determined in Step No. 11. Follow that column up to read the design concentration at maximum temperature. NOTE: If the maximum temperature, the Flooding Factor, the Design Concentration, or any combination of these items, are not listed, interpolation will be required. Complete this step for each area protected by the system. Example Maximum Ambient Temperature = 80 °F Flooding Factor = .484 Design Concentration = 38.9%

STEP NO. 13 – that the actual INERGEN agent concentration is within the design concentration range of 34.2% to 52% This step is used to that the “worst case” design concentration will not exceed limits for fire suppression on the low end and life safety on the high end. 34.2% INERGEN concentration relates to 13.8% oxygen concentration and 2.7% carbon dioxide concentration in a protected area, this is the minimum amount of INERGEN agent required for fire suppression of most fuels. This minimum concentration of INERGEN agent must be met in all cases. Failure to achieve this concentration may prevent suppression of a fire! 52% INERGEN concentration relates to 10.0% oxygen concentration and 4.2% carbon dioxide concentration in a protected space. This is the maximum amount of INERGEN agent allowed for normally occupied areas. NOTE: Normally occupied space is defined as “One that is intended for occupancy” by NFPA 2001. The appendix of NFPA 2001 states ”Spaces occasionally visited by personnel, such as transformer bays, switch-houses, pump rooms, vaults, engine test stands, cable trays, tunnels, microwave relay stations, flammable liquid storage areas, enclosed energy systems, etc., are examples of areas considered not normally occupied.” NOTE: Concentration may be between 52% to 62% in normally non-occupied areas if evacuation of these areas can be accomplished to limit exposure to less than 30 seconds. Refer to NFPA 2001, Paragraph 1-6.1.3, for detailed exposure conditions. Complete this step for each area protected by the system. Example 38.9% < 52%, therefore the system design is acceptable! STEP NO. 14 – Determine the Design Concentration at Normal Ambient Temperature Complete the same procedure as done in Step No. 12 using the Normal Ambient Temperature instead of the Maximum Ambient Temperature. Complete this step for each area protected by the system. Example Normal Ambient Temperature = 70 °F. Flooding Factor = .484 Design Concentration for all areas = 38.4%

STEP NO. 16 – Determine the Estimated System Flow Rate

STEP NO. 15 – Determine the 90% system discharge time

This step is required to estimate the Manifold Orifice Device size, the downstream pipe sizes, and to determine pressure-venting requirements.

APPLICATION METHOD (Continued)

This step is used to determine the discharge time for 90% of the agent. 90% of the agent is used by the flow calculation program instead of 100% because it provides a more accurate flow calculation due to the low pressures and flow rates associated with the final 10% of the agent discharge. NOTE: In most cases 90% of the agent will discharge from the system during the first half of the discharge time, the remaining 10% of agent will require approximately the same amount of time to discharge as the first 90%. The discharge time established in this step will assure that the agent concentration reaches 95% of the Minimum Design Concentration within 60 seconds as required by NFPA 2001. Varying the discharge time based on Design Concentration at Normal Ambient Temperature allows design of a system with lower flow rates and smaller pipe sizes because the extra agent (the amount over that necessary to reach 95% of Minimum Design Concentration) is discharged after 60 seconds. To complete this step, refer to the Discharge Time Chart on Page 5-21 in this section. Locate the Design Concentration determined in Step No. 14 in the left column and read to the right to determine the Discharge Time. Interpolation of the Design Concentration and Discharge Time may be necessary. Underwriters Laboratories limits the 90% discharge time of unbalanced INERGEN systems to 132 seconds. If the time determined from the Discharge Time Chart on Page 5-21 exceeds 132 seconds, and the system must be UL listed, the discharge time must be determined as 132 seconds. Complete this step for each area protected by the system. NOTE: Utilization of these discharge times is necessary to achieve 95% of the minimum design concentration within one minute. Example Design Concentration For All Areas = 38.4% Discharge Time = 84 seconds (Note: Discharge times less than or equal to those shown on the chart are acceptable)

!

CAUTION

The flow rates established in this and the following steps are estimated flow rates only. These flow rates are estimate solely for the purpose of estimating device sizes for quotation purposes. The flow calculation program will calculate actual system flow rates. To estimate the system flow rate (CFM), first multiply the total quantity of actual agent supplied by 0.9 (90%), and then divide that number by the total discharge time (in minutes). (Total agent supplied (from Step No. 9) x 0.9) ÷ discharge time (in minutes) NOTE: The flow rate established during this step is an estimated flow rate only. Actual system performance will most likely vary from that calculated here. It is the Designer’s responsibility to determine suitability of this estimate. It may be advisable to increase a pipe size if the estimate approaches the maximum flow rate for a given pipe size. Example 1144 ft3 Total Agent Supplied x 0.9 = 1030 ÷ 1.4 Discharge Time in Minutes = 736 CFM Estimated System Flow Rate STEP NO. 17 – Estimate the pressure reducer size required Using the flow rate established in Step No. 16, refer to the Pipe Sizing Estimation Chart (Manifold Pipe Size) on Page 5-14 to determine the estimated Pressure Reducer size. INERGEN manifolds require the use of Schedule 80 or Schedule 160 pipe depending on the size of pipe and ing methods. Threaded manifolds larger than 2 1/2 in. pipe size will require Schedule 160 pipe, welded manifolds will require Schedule 80 pipe in all sizes. NOTE: It may be in the Designer’s best interest to increase the estimated size if the estimated flow rate approaches the upper limit for the pipe size indicated, especially if Schedule 160 pipe is required. Example 736 CFM = 3/4 in. Pressure Reducer

Design APPLICATION METHOD (Continued) Total Flooding (Continued) STEP NO. 18 – Determine the Nozzle Quantity Nozzle quantity will be determined by many factors, such as size and shape of the hazard area, height of the ceiling, flow rates through the nozzles, available orifice sizes, etc. To determine the quantity of nozzles required, divide the area length by 32 ft. and then round up to the next whole number. Then divide the area width by 32 ft. and round up to the next whole number. Then, multiply the two answers to determine the total nozzle quantity. Complete this step for each area protected by the system. 360° NOZZLE REQUIREMENTS: • Maximum coverage length per nozzle – 32 ft. (9.8 m). • Maximum coverage width per nozzle – 32 ft. (9.8 m). • Maximum radial distance per nozzle – 22.6 ft. (6.9 m). The radial distance is defined as the distance from the nozzle to the farthest point of the area protected. • Nozzle should be placed as close to the center of the hazard as possible. On multiple nozzle systems, the nozzles should be as equally spaced as possible. 180° NOZZLE REQUIREMENTS: • Maximum coverage length per nozzle – 32 ft. (9.8 m). • Maximum coverage width per nozzle – 32 ft. (9.8 m). • Maximum radial distance per nozzle – 35.8 ft. (10.9 m). The radial distance is defined as the distance from the nozzle to the farthest point of the area protected. • Nozzle and/or deflector must be located within 6 in. (152 mm) of the wall of the hazard. • The index mark on the bottom of the nozzle must point at the center of the hazard. REQUIREMENTS COMMON TO ALL NOZZLES: • Maximum nozzle height above floor level for a single row of nozzles is 20 ft. (6.1 m). For ceiling heights over 20 ft. (6.1 m), an additional row of nozzles is required. • Minimum nozzle height above floor of hazard is 7 in. (178 mm). • If nozzle velocity is a concern, the designer may wish to add additional nozzles to lower the individual nozzle velocity to an acceptable limit. • If the room is an odd shape, the designer may wish to increase the nozzle quantity to provide a more even distribution of agent.

• For multiple level hazards, the intermediate levels of nozzles must be positioned at the top of the designed height for each intermediate level. Nozzles mounted at the ceiling must be within 12 in. (305 mm) of the ceiling. Example Computer Room • 20 ft. Length ÷ 32 = 0.625 = 1 nozzle • 13 ft. Width ÷ 32 = 0.406 = 1 nozzle • 1 nozzle x 1 nozzle = 1 nozzle for the computer room Subfloor • 20 ft. Length ÷ 32 = 0.625 = 1 nozzle • 13 ft. Width ÷ 32 = 0.406 = 1 nozzle • 1 nozzle x 1 nozzle = 1 nozzle for the subfloor STEP NO. 19 – Estimate Agent Flow Rate for Each Area This step estimates the total flow rate into each protected space to allow the designer to estimate nozzle sizes for quotation purposes. NOTE: This is an estimate only. It is the designer’s responsibility to assess the correctness of this estimate. If the flow rate approaches the top end of the allowable flow rate for a given size pipe, it may be in the Designers best interest to increase the pipe size. Multiply the actual agent quantity supplied for each area by 0.9 (90%) and then divide that result by the discharge time in minutes for the estimated flow rate for each area. Complete this step for each area protected by the system. Example Computer Room • 1040 ft3 Actual Agent Quantity Supplied x .9 = 936 ÷ 1.4 Discharge Time in Minutes = 669 CFM Estimated Flow Rate Per Area Subfloor • 104 ft3 Actual Agent Quantity Supplied x .9 = 94 ÷ 1.4 Discharge Time in Minutes = 67 CFM Estimated Flow Rate Per Area.

Page 5-8

Design APPLICATION METHOD (Continued) Total Flooding (Continued) STEP NO. 20 – Estimate the Nozzle Flow Rates If all of the nozzles within the hazard area will have the same flow rate, divide the Estimated Flow Rate for the Area (Step No. 19) by the nozzle quantity (Step No. 18). If all of the nozzles within the hazard area will not have the same flow rate, perform a percentage calculation using the volume protected by each nozzle divided by the total volume for the area and then multiply the Flow Rate for the Area (Step No. 19) by the volume percent calculated previously to determine the flow rate for that nozzle. Complete this procedure for each nozzle in the system. If the design includes multiple levels of nozzles, to include all nozzles on all levels in this step. Complete this step for each area protected by the system. Example Computer Room • 669 CFM (Estimated Flow Rate Per Area) ÷ 1 = 669 CFM Nozzle Flow Rate Subfloor • 67 CFM (Estimated Flow Rate Per Area ÷ 1 = 67 CFM Nozzle Flow Rate STEP NO. 21 – Determine the Nozzle Locations and Lay Out the Interconnecting Piping Using a plan view drawing of the protected areas, locate each nozzle and the cylinders. NOTE: Nozzles should be located at the top of the hazard area, aimed downward. Connect the nozzles with piping following the piping guidelines listed in the General Information Section and the Installation Section. After all of the nozzles are connected, lay out the piping to the cylinders and lay out the manifold. Manifold layout limitations can be found in the Installation Section of the Design Manual, including a manifold height chart. When laying out the manifold, that a center outlet manifold will usually allow the use of smaller pipe sizes for the horizontal legs of the manifold where the cylinders are connected, especially if these legs are a single size. “H” shaped manifolds are usually preferable to “end outlet,” “L,” or “U” shaped manifolds. Center to center distances for the cylinders will normally be 12 in. due to the spacing of the brackets. It is normally recommended to keep the Pressure Reducer as close to the manifold outlet as possible to reduce the amount of Schedule 80 or 160 pipe required in the system.

When selecting pipe schedules, keep in mind that the manifold pressure should be assumed to be 2,900 PSI. This will usually dictate the use of Schedule 160 pipe for any size larger than 2 1/2 in. pipe if threaded fittings will be used. If welded or “rolled groove” fittings are used in the manifold, Schedule 80 pipe will be acceptable in most cases for all pipe sizes through 6 in. If the system is a “Balanced” system, review the pipe layout to assure that all legs of the piping are equal in regards to flow and fittings and that the maximum length of pipe for the longest leg from the manifold to the furthest nozzle is not more than 10% longer than the shortest leg from the manifold to the closest nozzle. If the system is an “Unbalanced” system, review the piping arrangement for proper tee splits per the limitations listed in the General Information Section and revise the piping accordingly if necessary. If the system includes Selector Valves, refer to the information later in this section for assistance in laying out the piping for the Selector Valve manifold. STEP 22 – Complete an Isometric Sketch of the Piping Layout Create an isometric sketch of the piping for use in inputting the information in the INERGEN Designer program. After the sketch has been completed, identify all of the pipe lengths. Identify and label all node points, manifold designators, and nozzle designators. The first point on the manifold is considered as the inlet to the cylinder valve inside the cylinder. The second point is considered as the outlet of the discharge hose. This first section of pipe must always be included in any system; therefore the flow calculation program will include it automatically. • Piping Node Points – Piping sections are numbered starting at the inlet to the valve on the cylinder furthest from the manifold outlet. Each point where flow increases, direction changes, or flow splits marks the end of a pipe section and the start of a new pipe section. Nodes must be numbered numerically: 1, 2, 3, etc. Sequential numbering is not required, however, it is recommended to prevent confusion. NOTE: Anytime a tee is added to the piping to take off pressure to operate a pressure trip or pressure switch, a node point should be assigned and the fitting should be entered as a coupling to address the friction loss.


7-15-02

Page 5-9 REV. 1

Design APPLICATION METHOD (Continued) Total Flooding (Continued) • Nozzles – Nozzles are indicated with a number between 301 and 499. Sequential numbering is not required; however, it is recommended that the designer use some sort of numbering system to prevent confusion. • Manifold Designator – The manifold designator code is a number between 1 and 299. This code identifies the number of cylinders supplying any given section of the manifold. Example: A system with 38 cylinders supplying a section of pipe would, for that point, have a manifold designator of 38. Another system, having 102 cylinders supplying a section of pipe, would, for that point, have a manifold designator of 102. The first section of pipe chosen as a manifold designator must start with the designator code of 1. STEP 23 – Estimate Pipe Size for All Areas (Optional) To complete this step, start by labeling all nozzle flow rates. Then, working backwards from the nozzles, determine the flow rate for each section of pipe. Using the Pipe Size Estimation Chart on Page 5-14 of this section, estimate the pipe size for each section of pipe and the nozzles. Consider a pipe section as short if it is less than 20 feet in length. Consider a pipe section as long if it exceeds 20 feet in length; that these are estimates only. The designer may wish to judge the merits of selecting a long run if this is necessary. Selection of a long run will increase the pipe size due to increased friction loss encountered in long pipe runs. Flow rates for individual pipes in the manifold can be estimated by dividing the flow rate for the system (Step No. 16) by the number of cylinders in the system. Then multiply the result by the number of cylinders supplying that section of pipe. The flow calculation program will estimate pipe sizes automatically; therefore this step is optional. The designer may wish to use the pipe size estimation charts to estimate the nozzle pipe sizes for quotation purposes. NOTE: This is an estimate only. It is the designer’s responsibility to assess the correctness of this estimate. If the flow rate approaches the top end of the allowable flow rate for a given size, it may be in the Designers best interest to increase the pipe size. Example Computer Room • 669 CFM = 3/4 in. Nozzle Subfloor • 67 CFM = 1/4 in. Nozzle

STEP 24 — Determine the Open Area Required for Pressure Venting During Discharge It is necessary to calculate the opening area needed for pressure venting to determine if the hazard area(s) include sufficient openings or if more openings are required. Refer to the Pressure Relief Venting Guide, Part No. 422793, in the Appendix section for detailed information to determine free vent area required. If the enclosures wall strength cannot be determined, Ansul recommends a maximum wall strength of 5 lbs./ft2 unless the architect or owner provides a different value. See Page No. 3, Steps No. 1 and No. 3 in The Venting Guide for calculations to determine the Free Vent Area required. Example Computer Room • (2.7 x 1040 ft3) ÷ 1.4 = 2006 CFM, (2006 x 0.0855) ÷ sq. rt. of 5 PSF = 76.7 in2 Free Vent Area Required Subfloor • (2.7 x 104 ft3) ÷ 1.4 = 201 CFM, (201 x 0.0855) ÷ sq. rt. of 5 PSF = 7.7 in2 Free Vent Area Required STEP NO. 25 – Perform Flow Calculations With the information developed in Steps No. 21 and 22, run the computer program to determine the final pipe sizes, nozzle orifice sizes, and pressure reducer size. If the system protects more than one area by use of Selector Valves, the flow calculation for the worst system from a hydraulic flow standpoint should be calculated first. Once the pipe sizes for this system are selected, the manifold for all of the other systems must use the same size pipe. These pipe sizes must be entered manually. Pipe sizes starting with the outlet from the Selector Valve manifold, including the section immediately before the Selector Valve, can be estimated by the flow calculation program.

Design APPLICATION METHOD (Continued) Total Flooding (Continued) STEP NO. 26 – Revise the Design Worksheet (Optional) This step is to be completed only if the designer is completing the INERGEN Design Worksheet manually; the INERGEN Designer program automatically revises the Design Worksheet after a flow calculation is completed. Rework the design worksheet for each area starting with the entry for “Actual INERGEN Agent Supplied Per Area, Step No. 10,” and ending with “System Discharge Time, Step No. 15.” Replace the “actual INERGEN agent supplied per area” with the agent quantities determined in the “Nozzle Performance” section of the flow calculation program. STEP NO. 27 – Actual System Performance Once a flow calculation has been completed and the Design Worksheet has been revised (optional), it is important that the designer review all results to system performance. The INERGEN Designer program will flag most errors and prevent a completed flow calculation until they have been corrected. However, this does not guarantee that the systems performance will match what the designer expects. Careful review is an important step in the design of any Fire Protection system, which must be completed before final approval of the system. Review the revised worksheet to that: 1. The agent concentration at maximum temperature is within acceptable limits (34.2% to 52% for occupied spaces). 2. The agent quantity is above the amount required in the Initial INERGEN Quantity box (see Step No. 7). 3. The discharge time from the flow calculation is equal to or less than that listed for all areas on the Design Worksheet.

STEP NO. 28 – Determine the Pilot Cylinder Requirements After all flow calculations have been completed, refer to the following table, “Pilot Cylinder Requirements Table”, to determine if additional pilot cylinders are required in the system. Proper backpressure actuation of the INERGEN cylinder valves requires that the manifold reach a prescribed minimum pressure. If this minimum pressure is not achieved in the manifold, only the cylinder operated by the electric actuator will open. This will result in a system discharge which will not allow enough agent to the hazard enclosure, which may prevent achievement of the proper minimum design concentration and result in the failure to suppress a fire. The pilot cylinder requirements identified on the “Pilot Cylinder Requirements Table” allows pressure from the electric actuator to operate as many pilot cylinders as necessary to assure that the manifold reaches a pressure high enough to open all cylinders attached to that manifold. Example (Estimated Pilot Cylinder Requirement) System Flow Rate = 736 CFM (1) Pilot Cylinder Required

STEP NO. 29 – Complete Layout of the System At this point, all final details of the system can be finalized. These details include: design of the Pilot Cylinder Actuation system, bracketing, actuation components, etc. STEP NO. 30 – Create a Bill of Materials Create a list of all materials necessary to install the system. This can be done by hand or by use of the Bill of Materials Tab in the INERGEN Designer program.

STEP NO. 31 – Create Installation Drawings The final step in the design of an INERGEN system is completion of installation drawings for submittal to the appropriate authority and the customer. These drawings should include all details necessary for installation of this system.

SELECTOR VALVE SYSTEMS The following information must be considered when deg a selector valve system. • Each hazard area must be treated as a separate system design. • Start with the largest system (system with the highest estimated flow rate). This is necessary so that the manifold size will handle the maximum quantity of INERGEN. • After calculating the largest system first, complete additional system calculations on the remaining systems. Use the manifold pipe size calculated from first system design (system with the highest flow rate). • Selector valve systems can be used for multi-hazards when all areas are considered separate fire hazards. • Selector valve can be located either upstream or downstream of the pressure reducer. • The piping located between the pressure reducer and the selector valve must be rated for pressure of 2900 psi (200 bar) or greater. • Maximum distance between selector valve and pressure reducer is 20 ft. (6.1 m). • When deg the manifold for a selector valve system, check valves must be installed in the manifold to separate the actuation of the smaller system(s) from the larger ones. • A minimum of 10 pipe diameters is required between the pressure reducer and the selector valve. The pressure reducer can be located either before or after the selector valve. • If the pressure reducer is downstream of a selector valve, each pressure reducer must utilize its own individual selector valve. The following are four typical examples of selector valve systems:

Design SAMPLE APPLICATIONS Refer to Section XI (Typical Applications) for examples of some typical applications. By reviewing these examples, it may help answer some questions concerning the total design process.

Electric Actuation

ACTUATION REQUIREMENTS

Normal system design requires that only one pilot valve contains an electric actuator. On multiple cylinder systems, the additional cylinders are actuated by the pressure generated within the distribution manifold.

Three types of actuation are available for the INERGEN system: manual, pneumatic, and electric. Manual Actuation Manual actuation can be used with or without automatic detection. When no detection is required, based on acceptance by the authority having jurisdiction, the lever actuator can be mounted on top of the INERGEN cylinder valve. The manual lever release actuator provides a manual means of agent cylinder actuation by direct manual actuation of its pull lever or cable actuation when used in conjunction with a remote manual pull station. One pilot cylinder valve is required on multiple cylinder systems. The pilot valve is the only one that requires a manual actuator. On two or more cylinder systems, the remaining cylinders are actuated by the pressure generated within the distribution manifold. The maximum length of actuator cable which may be used in the remote line is 125 ft. (38 m). The maximum number of corner pulley elbows is 10. Pneumatic Actuation Pneumatic actuation is accomplished by supplying pressure to the pilot port on the INERGEN cylinder valve. The pressure is supplied from an LT-30-R nitrogen cartridge located in the ANSUL AUTOMAN II-C release. The cartridge pressure pneumatically opens the cylinder valve. One pilot valve is required in single or multiple cylinder systems. The rest of the cylinders will be actuated from the pressure of the pilot cylinder. The maximum length of 1/4 in. Schedule 40 pipe is 100 ft. (30.5 m). If it is necessary to have an actuation pipe run which exceeds the maximum allowable 1/4 in. pipe requirements, 1/4 in. O.D. stainless steel tubing with a wall thickness of 0.065 can be used for the actuation line. When this size tubing is used, a maximum of 300 ft. (91.4 m), with no reductions for elbows or tees, is allowed. See NFPA 2001, Paragraph 2-3.4.2 for information on pneumatic control equipment

CV-98 Valve – One or two HF electric actuators, Part No. 73327, can be used on a single release circuit. When using only one electric actuator, an in-line resistor, Part No. 73606, must always be used.

In auxiliary or override applications, a lever actuator can be installed on top of the CV-98 valve or on top of HF electric actuator. Multiple Manifold Actuator A maximum of 40 cylinders can be installed on a single manifold and actuated from a single actuated main pilot valve. When more than 40 cylinders are required, up to 12 additional pilot valves (12 additional manifolds each having a maximum of 40 cylinders) can be pneumatically actuated from the “pilot” manifold. See Installation Section VI for detailed piping requirements. “Secondary” Pilot Cylinders On some very large systems, because of the manifold size, “secondary” pilot valves are required to be actuated from the single “main” pilot valve in order to produce enough manifold pressure to operate the remaining cylinders on the manifold. See “Pilot Cylinder Requirement Table” in Step No. 28, Page 5-10, for detailed secondary pilot cylinder information.

Design ACCESSORIES

Pressure Switch

Specific selection and placement of accessories that may be used with the INERGEN system are:

The pressure switch is operated by the INERGEN agent pressure when the system is discharged. The piping to the pressure switch is normally run from the distribution manifold but can also be run from an ANSUL AUTOMAN Release Cartridge. The pressure switch can be used to open or close electrical circuits to either shut down equipment or turn on lights or alarms or to signal the control .

Mechanical Manual Pull The mechanical manual pull station allows the INERGEN system to be manually operated at some point distant from the control system or cylinders. The pull station should be installed at a maximum height of 60 in. (15.2 cm) and located in the path of exit. The total length of wire rope used for each mechanical manual pull station within a system must not exceed 125 ft. (38 m). The maximum number of pulley elbows that may be used per pull station is 10. Parts that are required for installation of a remote manual pull station, either electric or mechanical are:

The piping required to connect from the system manifold to the pressure switch is 1/4 in. Schedule 40 (if connected to distribution piping), or Schedule 80 (if connected to manifold). Maximum length of 1/4 in. piping from INERGEN manifold to all accessories must not exceed 100 ft. (30.5 m). Pressure switches that may be used on system are: Description

The pressure trip is connected to the actuation or discharge line of a INERGEN system. By either pneumatic or manual actuation, the pressure trip can release spring or weight powered devices to close doors and windows, open fuel dump valves, close fire dampers or close fuel supply valves. Piping to the pressure trip must be determined based on the maximum pressure at point of connection. Refer to Estimation Chart (Pipe Pressure) in Appendix Section to determine required schedule and grade. Pressure trip piping connection must be made to the system piping at the point where the system piping is closest to the pressure trip installed location. Maximum length of 1/4 in. piping to all accessories must not exceed 100 ft. (30.5 m). Pressure trip that may be used on system is: Description

Design ACCESSORIES (Continued) Alarms Several types of electric alarms are available. Each of these operate on 24 VDC and must be used on the alarm circuit of an AUTOPULSE Control System. Refer to appropriate AUTOPULSE Control System installation, maintenance, and recharge manual for detailed design information. 120 VAC alarms are also available to use with an ANSUL AUTOMAN II-C Releasing Device. Control s The AUTOPULSE Control System is the only approved detection and alarm system for use with the INERGEN fire suppression system. Several styles of AUTOPULSE s are available. Refer to appropriate AUTOPULSE Control System installation, maintenance, and recharge manual for detailed design information.

– Protection of other hazards if selector valves are involved and multiple hazards are protected by the same set of cylinders. See selector valve information on Page 5-11. If a full complement of charged cylinders cannot be obtained, or the empty cylinders recharged, delivered and reinstalled within 24 hours, a third complement of fully charged spare cylinders should be maintained on premises for emergency use. The need for spare cylinders may depend upon whether or not the hazard is under protection of automatic sprinklers.” When deg a system, always determine if, and what kind of, reserve system is required. NOTE: Usage of reserve systems with primary system may make hazard area unsafe for normal occupancy.

DEVELOP BILL OF MATERIALS RESERVE SYSTEM Normally the authority having jurisdiction will determine whether a hazard requires a reserve set of INERGEN cylinders, either connected or spares. NFPA 2001, Standard on Clean Agent Fire Extinguishing Systems, states: “Where required, the reserve quantity shall be as many multiples of the primary supply as the authority having jurisdiction considers necessary.” “Where uninterrupted protection is required, both primary and reserve supply shall be permanently connected to the distribution piping and arranged for easy changeover.” IRI (Industrial Risk Insurers) requires the following: “In high pressure systems an extra full complement of charged cylinders (connected reserve) manifolded and piped to feed into the automatic system should be provided on all installations. The reserve supply is actuated by manual operation of the main/reserve switch on either electrically operated or pneumatically operated systems. A connected reserve is desirable for four reasons: – Protection should reflash occur. – Reliability should the main bank malfunction. – Protection during impairment when main tanks are being replaced.

After completing the subsections of the design section, finalize the system design by completing a bill of material for the system. The bill of material, hazard sketches, hydraulic calculations, and any notes, should be kept on file for future reference.

Installation

®

All installations are to be performed in accordance with the parameters of this manual and all appropriate codes and standards from the local, state, and federal authority having jurisdiction. Before the INERGEN system is installed, the qualified installer should develop installation drawings in order to locate the equipment, to determine an actuation and distribution piping routing, and to develop a bill of material. For successful system performance, the INERGEN system components must be located within their approved temperature ranges. The ambient temperature range is 32 °F to 130 °F (0 °C to 54 °C). All AUTOPULSE Control Systems are designed for indoor applications and for temperature ranges between 32 °F to 120 °F (0 °C to 49 °C).

MOUNTING COMPONENTS Cylinder/Bracket Assembly INERGEN cylinders may be located inside or outside the protected space, although it is preferable to locate them outside of the space. They must not be located where they will be exposed to a fire or explosion in the hazard. When they are installed within the space they protect, a remote manual control must be installed to release the system safely from outside the hazard area. The cylinders should be installed so that they can be easily removed after use for recharging. Cylinders must be installed indoors. Do not install the cylinders where they are exposed to direct sun rays. Cylinders may be installed horizontal if properly bracketed. See Figures 1 through 4 for detailed mounting height information for all cylinder bracketing.

Installation MOUNTING COMPONENTS (Continued) 1. Mount each INERGEN cylinder by completing the following: !

Before installing any actuation piping, the piping design must be determined. This will confirm that the lengths of actuation piping does not exceed the maximum allowable.

CAUTION

General Piping Requirements

Do not remove the safety shipping caps at this time. They are provided to prevent accidental actuation and discharge during shipping and handling. If valve assembly is accidentally operated, velocity of unrestricted escaping gas is forceful enough to cause injury, especially about the face and head. a. Assemble bracket components. See Parts List, located in the Appendix Section, for details of cylinder bracketing and component assembly. b. If a reserve system is being installed, mount the reserve cylinder(s) directly next to the main system cylinder(s). !

INSTALLING ACTUATION PIPING

CAUTION

Proper fasteners must be used when mounting cylinder bracketing to wall or . Failure to properly mount could cause cylinder movement upon discharge. c. Securely mount bracketing to rigid wall or . d. Fasten cylinder(s) securely in bracketing. Releasing Devices Different types of Releasing/Detection systems are available with the INERGEN system: – ANSUL AUTOMAN II-C release using thermal detectors with pneumatic actuation. – AUTOPULSE Control System using electric detection with electric actuation. – AUTOPULSE Control System with electric detection utilizing an ANSUL AUTOMAN II-C release for pneumatic actuation. For detailed information on detection systems, refer to the following: Ansul Detection and Control Application Manual NFPA 72–National Fire Alarm Code NFPA 70–National Electrical Code

1. Use only 1/4 in. Schedule 40 black iron, hot-dipped galvanized, chrome-plated, or stainless steel pipe/braided hose and fittings conforming to ASTM A120, A53, or A106. 2. The maximum length of all 1/4 in. Schedule 40 pipe is 100 ft. (30.5 m). 3. Before assembling the pipe and fittings, make certain all ends are carefully reamed and blown clear of chips and scale. Inside of pipe and fittings must be free of oil and dirt. 4. The piping and fitting connections must be sealed with pipe tape. When applying pipe tape, start at the second male thread and wrap the tape (two turns maximum) clockwise around the threads, away from the pipe opening. NOTICE Do not allow tape to overlap the pipe opening, as this could cause possible blockage of the gas pressure. Thread sealant or compound must not be used. 5. Cast iron pipe and fittings are not acceptable. 6. Actuation piping must be rigidly ed by UL listed hangers as described on Page 6-6.

Manual actuation is accomplished by pulling the valve hand lever. The lever design contains a forged mechanical detent which secures the lever in the open position when actuated.

CAUTION !

Make certain actuator is reset before installing on cylinder valve. Failure to do so will cause system actuation. Pneumatic Actuation For CV-98 Valve To install pneumatic actuation, complete the following steps: 1. Remove the 1/8 in. pipe plug from the 1/8 in. actuation port. 2. Attach adaptor (Part No. 873236), male elbow (Part No. 832334), and 1/4 in. high pressure hose (depending on length required, Part No. 31809, 32335 or 32336) to 1/4 in. actuation port. See Figure 11. Securely tighten.

CAUTION

Before mounting the lever actuator(s) on the cylinder valves, make certain the lever actuator is in the “SET” position. If the lever actuator is not in the “SET” position, cylinder will discharge when lever actuator is installed. See Figure 12 for installation details. MUST BE IN THE SET POSITION BEFORE INSTALLING

3. If necessary, perform an enclosure integrity (door fan) test prior to running the INERGEN system discharge test. This will confirm that total venting area is not too great for the hazard to adequately contain the desired INERGEN agent concentration. 4. Set up the recording equipment outside of hazard area. Ansul recommends using the following equipment: – Nova Model 308 BWP portable oxygen and carbon dioxide analyzer – M-Tek Model 312 two pen, four in., multi-range, multi-speed chart recorder Ansul recommends that the oxygen and carbon dioxide concentrations be monitored from a single point within the protected space. The source for the monitoring point will be the hazard most likely considered the fire source. In the case of total room protection with multiple hazards, the monitoring point should be halfway up at the center of the room. 5. NOTE: If the system is to be fired manually, disconnect the electric actuator to prevent firing from a pressure switch and control . Actuate INERGEN system and monitor recording equipment. In order to meet the design concentration, the Oxygen and CO2 levels must meet the values in Table 1. The oxygen concentration must not exceed 15% throughout the hold time determined by the AHJ.

TESTING SELECTOR VALVE When utilizing selector valves in the distribution piping network, make certain all selector valve internal actuators are in the “SET” position.

INERGEN % 34.2

Oxygen % (Equal to or Less Than) 13.8

Inspection Inspection is a “quick check” that a system is operable. It is intended to give reasonable assurance that the system is fully charged and will operate. This is done by seeing that the system has not been tampered with and there is no obvious physical damage, or condition, to prevent operation. The value of an inspection lies in the frequency, and thoroughness, with which it is conducted. Systems should be inspected at regular monthly intervals, or at more frequent intervals when circumstances require. The following visual checks should be performed during an INERGEN system inspection: – Visually inspect the hazard area to that it has not changed. Look for different fuels, new equipment, blocked open doors or dampers. – Check detectors to make certain they are in place, not damaged or coated with dirt, grease, paint, or any contaminating substance. – Check all manual pull stations to assure they have not been tampered with and are not blocked from use. – Check all alarm devices for damage, dirt, corrosion, etc. – Check that the piping is secure and nozzles are in place. Make certain the nozzles are not covered with dirt, grease, or paint and that there is nothing structural blocking the discharge. – Visually inspect all components for signs of damage, such as disconnected or loose parts, corrosion, twisted or dented components, etc. – Check each INERGEN cylinder indicator (gauge) to determine that the cylinder pressure is in the operable range. – that all pressure switches are in place and are in the correct, nonoperated, position. – Visually that control and/or releasing device is functioning properly. – Perform any other checks that may be required by the authority having jurisdiction. – that the pressure reducer/union contains an orifice plate by visually noting the presence of the orifice indicator tab on the side of the union.

– If applicable, push green poppet valve near solenoid on selector valve to relieve any pressure. – Visually check solenoid or electric actuator wiring on selector valve to make certain it has not been disconnected. – Make certain lever actuator on selector valve is in “SET” position. – Record that the system has been inspected and inform the proper personnel.

Maintenance ANNUAL MAINTENANCE EXAMINATION General Systems shall be maintained at regular intervals, not more than one year apart, or when specifically indicated by an inspection. (Exception: Cylinder pressure must be checked every six months per NFPA 2001.) Maintenance is a “thorough check” of the system. It is intended to give maximum assurance that a system will operate effectively and safely. It includes a thorough examination and any necessary repair, recharge, or replacement. It will reveal if there is a need for hydrostatic testing of the cylinder. The procedures listed in this section are the minimum that is necessary to maintain a system. If circumstances warrant them, a more thorough procedure should be followed to assure system performance. Make certain that all people affected by the maintenance are informed before you start. This may include the owner, security personnel, the local Fire Department, and possibly local workers that may be affected by equipment shutdown or start up. NOTICE If the system includes an ANSUL AUTOMAN II-C releasing device, before proceeding with annual maintenance examination, insert lock pin in ANSUL AUTOMAN II-C release and remove nitrogen cartridge. Install safety shipping cap on cartridge. 1. Survey the hazard to make certain it has not changed from what the system was designed to protect. While surveying the hazard, look for different fuels, loss of hazard integrity, new hazards, etc. 2. Check all nozzles to make certain they are in place, that the orifice plates are in place and with the proper orifice. Check the condition of the nozzle for corrosion or damage and make certain it is not obstructed internally or externally. 3. Check the condition of the piping to make certain that it is properly secured in the hangers and that all fittings are connected tightly. 4. Check all warning nameplates throughout the area. Make certain they are in place, mounted securely, readable, and are not damaged. 5. Check all cylinder bracketing. Make certain all cylinders are secured in the brackets. Check for corrosion, damage, or missing components.

6. Check the condition of all cylinders. Look for signs of damage or corrosion, and check the cylinders last hydrotest date. (NFPA 2001 states “Cylinders continuously in service without discharging shall be given a complete external visual inspection every five years or more frequently if required. The visual inspection shall be in accordance with Compressed Gas Association Pamphlet C-6, Section 3; except that the cylinders need not be emptied or stamped while under pressure.”) Using the Pressure Test Gauge Assembly (Part No. 427953 for CV-98 valves), check each cylinder to determine if pressure is within the acceptable range. See Pressure Correction Chart in the Appendix Section. To use the pressure test gauge assembly, first make certain cylinder is properly bracketed. Before attaching assembly, make certain stem is completely backed out by turning hand wheel counterclockwise until it stops. Attach the assembly to the fill inlet por t of the INERGEN cylinder valve. Wrench tighten. To read the cylinder pressure, turn handwheel completely clockwise until it stops, then back it off 1/4 turn. This will open the fill port. After pressure has been read, close fill port by turning handwheel completely counterclockwise. Slowly loosen the adaptor nut to remove the pressure test gauge assembly from the fill port. While removing this, you may hear a small hiss of pressure remaining in the assembly. This is normal and will not last long. You will also notice the gauge pressure will drop to zero. Record the cylinder pressure for reference on the next pressure test. Visually note the location of the indicator needle on the cylinder valve to determine if it is in close proximity to the actual reading of the test gauge. 7. Check condition of all cylinder discharge hoses. Look for signs of structural problems like abrasions or weather checking. Make certain all hoses are connected properly. All hoses must be tested every 5 years. Refer to NFPA 2001 for detailed testing requirements.

Example – Computer Room and Subfloor

Electronic data processing involves storage, recall and use of information via electronic equipment. Electronic data processing equipment is found in almost every industry today. The equipment is very sensitive and operates within minute tolerances. Additionally, many computer installations are designed with a subfloor area containing data and power cable bundles.

Thermal detectors are used as a backup automatic system.

Because of the high dollar valve of the equipment, the data managed by that equipment and the productivity provided by electronic data processing, rapid detection and efficient fire protection are imperative. Time lost to cleanup and ventilation of a computer room means lost time throughout the company, so these areas require a clean, no residue gas agent that disperses easily.

A subfloor having dimensions of 20 ft. x 13 ft. x 1 ft.

The authority having jurisdiction may have additional requirements. HAZARD A computer room having dimensions of 20 ft. x 13 ft. x 10 ft. No unclosable openings. Ventilation to be shut down at system actuation. No. 1 – Sketch of Hazard. Do an accurate sketch of the hazard area and record all dimensions and solid objects.

The computer room and subfloor space can be protected with an INERGEN suppression system, even when the computer room is normally occupied.

No. 2 – Preliminary Drawing – Complete a draft sketch of the piping layout to determine pipe lengths and number of fittings. Locate and number all node points, manifold designators, and nozzles.

Fires can occur within the computer electrical insulation and in the cable bundles in the subfloor. Paper debris that has been allowed to accumulate in the subfloor is also a source for ignition.

No. 3 – Pipe Input Section – Complete the Pipe Input Section (tab) of the INERGEN Designer Program. Once completed, print out the pipe input results.

Computer room/subfloor protection can be accomplished by installation of a total flood INERGEN system. The INERGEN system is designed in accordance with the Ansul design, installation manual and NFPA Standard 2001, “Standard for Clean Agent Fire Extinguishing Systems,” which states, “the design concentration must be achieved within 1 minute. It is important that an effective agent concentration not only be achieved, but shall be maintained for a sufficient period of time to allow effective emergency action by trained personnel.” The INERGEN system consists of a cylinder bank, a piping arrangement and discharge nozzles located in the room and subfloor space. Occasionally, drainage is installed in the subfloor area. Provisions must be made for making the drain piping a closed system unless water is present to assist in assuring the necessary concentration. When the computer room is normally occupied, personnel safety is of first concern. Alarms or warning devices must be located in the room to provide sufficient annunciation of INERGEN agent discharge. The room and subfloor must be tight to prevent loss of INERGEN agent. All air handling equipment must be shut down and dampered prior to system discharge. Smoke detectors, operated by an electronic control , are usually employed with an INERGEN system to provide detection and thus suppression of a fire before it has a chance to do serious damage.

No. 4 – INERGEN Flow Calculation – Perfor m the INERGEN Flow Calculation and print out the Flow Report and the Nozzle Performance Report from the INERGEN Designer Program. No. 5 – Review Design Concentration and Discharge Time – Return to the Design Section (tab) of the INERGEN Designer Program and review the design concentration and discharge time for each hazard area to system performance. Also, at this point, that the piping used in the down stream piping is acceptable for the pressures identified as maximum down stream pressure on the INERGEN Designer Flow Report.
