Figure 1.1 - FM-200 Typical System Components

1 GENERAL INFORMATION AND SAFETY PRECAUTIONS

1.1 GENERAL

The Chemetron Beta and Gamma series systems are automatic fire suppression systems. Thesesystems use the FM-200 (HFC-227ea) chemical agent and consist of three basic components. Thebasic components used for these systems are (refer to Figure 1.1):

Storage/Distribution ComponentsControl PanelsDetection and Alarm Devices

1. The storage components consist of the agent containers, container supports (racks), piping anddischarge nozzles for the distribution of the extinguishing agent.

2. The control panel is the brain of the system and is used to monitor the detection and accessories.

3. The detection, alarm devices, and accessories are the external devices that act as the eyes andvoice of the system as they give audible or visual signals.



S/N 30000030


The systems offer fire suppression in accordance with the National Fire Protection Association (NFPA)NFPA 2001 - Standard on Clean Agent Fire Extinguishing Systems, NFPA 70 - National Electrical Code,NFPA 72 - National Fire Alarm Code, and the guidelines contained in this manual. The system andits components should only be used for total flooding applications, not local application protection.A total flooding application can be defined as injecting FM-200 into a room, area, or compartment thathas the structural integrity to retain the agent that has been discharged. The design of such a systemrequires that the FM-200 chemical agent be discharged from its container within 10 seconds and bethoroughly mixed throughout the room or area, reaching a minimum concentration level of 6.25% butnot exceeding 9% in normally occupied spaces.

When designed and installed using the information contained in this manual, the system meets theapproval of Factory Mutual Research Corporation (FMRC), Underwriters Laboratories Inc. (UL), andUnderwriters Laboratories of Canada (ULC). The flow calculation method has been verified basedon an ambient temperature of 70F 10F (21.1C 5.5C). Installation of cylinder/valve assembliesoutside this range for the ambient temperature limits of 32F (0C) to 130F (54.4C) may result inthe calculation not being accurate and consequently, the required quantities of agent may not bedischarged from one or more nozzles.

FM-200 Beta and Gamma series systems can be designed in a variety of different arrangements. Themost basic will be a single storage rack. The controls used for operation can be manual, automatic,or both.

NOTE

MANUAL-ONLY ACTUATION IS PERMITTED ONLY IF IT IS ACCEPTABLE TO THE AUTHORITY HAVING JURISDICTION(NFPA 2001).

The Chemetron Beta and Gamma series systems use FM-200 to suppress fires in specific equipmentor hazards requiring an electrically non-conductive agent and that may be occupied. FM-200 may beused in the protection of the following types of facilities:

Data processingProcess control roomsTelecommunications facilitiesHigh value assets

FM-200 can be used in the hazards previously listed for Class C electrical fires, Class A surface burningfires where the potential for a deep-seated type fire condition does not exist, or Class B flammableliquid fires.

Clean agents shall not be used on fires involving the following materials unless they have been testedto the satisfaction of the authority having jurisdiction:

1) Certain chemicals or mixtures of chemicals, such as cellulose nitrate and gunpowder, that arecapable of rapid oxidation in the absence of air

2) Reactive metals such as lithium, sodium, potassium, magnesium, titanium, zirconium, uranium,and plutonium

3) Metal hydrides

1.2 Physical and Chemical Properties

FM-200 (CF CHFCF - heptaflouropropane) is a compound that consists of carbon, fluorine and3 3hydrogen. It is colorless, odorless, electrically non-conductive, and suppresses fire by interrupting thecombustion process and affecting the available oxygen content in the area of the discharge.

FM-200 is clean, efficient, environmentally acceptable, and leaves no residue, thus minimizing anydowntime after a fire. If exposed to temperatures greater than 1300F, toxic products of decomposition(hydrogen fluoride) are formed. The system should be designed to discharge between a minimumdischarge time of 5 seconds and a maximum discharge time of 10 seconds. The amount of toxic by-products formed during extinguishment of flames is greatly reduced by discharging the agent in lessthan 10 seconds. Most materials contained in areas protected by FM-200, such as aluminum, brass,rubber, plastics, steel, and electronic components, are unaffected when exposed to FM-200.

FM-200 is stored as a liquid in steel containers and superpressurized with nitrogen to 360 psig (2482kPa) to increase its discharge flow characteristics. When discharged, FM-200 will vaporize at thedischarge nozzles and effectively mix with the air throughout the protected area.

1.3 Safety Considerations

FM-200 shall be used in accordance with the proposed United States Environmental Protection Agency(EPA) Significant New Alternatives Policy (SNAP) program rules.

FM-200 has acceptable toxicity for use in occupied spaces as a total flooding agent with specificlimitations. Refer to the proposed SNAP rules for these limitations.

In accordance with NFPA Standard 2001, the following shouldapply:

Any unnecessary exposure to FM-200, even at NOAELconcentrations of 9% or below, and FM-200 decompositionproducts shall be avoided. The requirement for predis-charge alarms and time delays are intended to preventhuman exposure to agents. The following additionalprovisions shall apply in order to account for failure ofthese safeguards:

(a) FM-200 systems for spaces that are normallyoccupied and designed to concentrations up to the NOAELshall be permitted.

(b) FM-200 systems for spaces that are normallyoccupied and designed to concentrations above theNOAEL and up to the LOAEL (above 9% and up to 10.5%)shall be permitted, given that means be provided to limitexposure to no longer than the time specified in Table 1.3corresponding to the given design concentration.

(c) In spaces that are not normally occupied andprotected by an FM-200 system designed to concentrationsabove the LOAEL of 10.5%, and where personnel could possibly be exposed, means shall beprovided to limit exposure times using Table 1.3.

(d) In the absence of the information needed to fulfill the conditions listed, the followingprovisions shall apply:

(1) Where egress takes longer than 30 seconds but less than 1 minute, the FM-200 shall notbe used in a concentration exceeding its LOAEL of 10.5%.

(2) Concentrations exceeding the LOAEL are permitted only in areas not normally occupiedby personnel provided that any personnel in the area can escape within 30 seconds. Nounprotected personnel shall enter the area during agent discharge.

The discharge of FM-200 into a hazard may cause a reduction in visibility for a brief period. Any directcontact with the agent can cause frostbite.

A cylinder containing FM-200 should be carefully handled. All anti-recoil devices must be in placeat all times when the cylinder is not restrained.



S/N 30000030


The Material Safety Data Sheet (MSDS) (see Appendix) covering FM-200 should be read and under-stood prior to working with the agent. Safety items such as personnel training, evacuation plans andfire drills should be considered. Personnel should also be acquainted with the fact that FM-200sometimes presents a noise hazard during discharge.

1.4 Agent Decomposition Consideration

When FM-200 is exposed to a fire or other hot surfaces, the products of decomposition that result area hazard to personnel. The effects of FM-200 decomposition on equipment should be considered inhazards with high ambient temperatures (e.g., furnaces and ovens).

2 SYSTEM DESCRIPTION AND OPERATION

Each FM-200 system is specifically designed to accommodate the individual demands of the areasto be protected. The wide range and design of available components provides the flexibility necessaryfor this custom design.

The following sections describe the operation and function of all controls and indicators that are usedwith Chemetron Fire Systems Beta and Gamma Series FM-200 Systems. The flow calculation methodhas been verified at an ambient temperature of 70F (21.1C). When the FM-200 storage temperaturevaries by 10F (5.5C) from 70F (21.1C), there is a risk that the system will not supply the designedquantity of extinguishing agent.

2.1 Beta System (Refer to Figure 2.1)

2.1.1 Cylinder Assembly

FM-200 is stored in specially designed cylinder assemblies. Beta series cylinders are available in threedifferent capacities and are charged with FM-200 to filling densities from 35 lb/ft (561 kg/m ) to 703 3

lb/ft (1121 kg/m ) of cylinder volume. All cylinders are superpressurized with dry nitrogen to a pressure3 3

of 360 psig (2482 kPa) at 70F (21C). Each cylinder is equipped with an identification nameplateindicating the quantity of FM-200.

The standard cylinder assembly, having a rigid dip tube, is designed for mounting in a vertical positiononly. The cylinder assembly is composed of a cylinder, dip tube, and cylinder valve.

A. Cylinder: The steel cylinders are manufactured to the requirements of the Department of Transpor-tation (DOT) for compressed gas and have external neck threads for cylinder valve connection.

B. Dip Tube: A flanged dip tube extends from the cylinder neck down to within approximately 5/8in. (16 mm) of the bottom of the cylinder. The flange, clamped between the top of the cylinder neckand the cylinder valve, supports the dip tube.

C. Cylinder Valve: A pressure operated cylinder valve having a forged brass body and cap is attachedto the cylinder neck and serves to control the flow of FM-200 from the cylinder. A synthetic rubberseat disc and disc carrier are connected by a stem to an operating piston at the top. The pistonto valve ratio is approximately 3 to 1.

The cylinder valve has five connections, as follows:

1. Manual-Pneumatic actuator Connection: This is a threaded connection housing a check valveand serves as the attachment point for the manual-pneumatic actuator and for cylinder fillingoperations.

2. Pressure Gauge/Solenoid Pilot Valve Assembly Connection: This is a threaded connectionhousing a check valve and serves for the attachment of:

a. Solenoid pilot valve assembly (with pressure gauge) for pilot cylinders.

b. Pressure gauge assembly for all other system cylinders.

3. Safety Burst Disc Connection: A frangible safety disc is connected to the valve body and servesas a pressure relief device to protect the cylinder against excessive internal pressure. Its disc rupturepoint is in the range of 850 psi to 1000 psi (5860 kPa to 6895 kPa).

4. Discharge Connection: A 1-1/2 in. O.D. flare connection serves as the discharge port.

5. Pilot Connection: A 1/4 in. (6 mm) NPT tap in the cylinder valve cap provides a means of applyingpilot pressure above the operating piston.

2.1.2 Discharge Tube Assembly

A formed, 1-1/2 in. O.D. steel tube assemblywith a flare nut at each end is used toconnect the cylinder valve to a maleconnector (refer to Figure 2.1.2), whichcan then be connected to the dischargepiping system.

2.1.3 Discharge Connection Fitting

A 1-1/4 in. (32 mm) male connector is usedto attach a cylinder to the discharge pipingsystem (refer to Figure 2.1.3a).

OR Check Valve

(Refer to Figure 2.1.3b) A check valve is used betweenthe cylinder valve discharge outlet flexible connection andthe discharge manifold. The check valve prevents backflow from the manifold in the event that the system isdischarged when one or more cylinders are disconnected,such as for weighing or general servicing. A check valveis not required on single cylinder systems.

2.1.4 Solenoid Pilot Valve Assembly

(Refer to Figure 2.1.4) The system utilizes a solenoidpilot valve assembly to provide pilot pressure foractuation, whether system actuation is by automatic(detection device) or manual-electric (pushbutton) means.

The solenoid pilot valve assembly includes a pressuregauge and adapter with swivel nut, vented elbow, and O-ring seal that is attached to the pressure gaugeconnection of the cylinder valve. The adapter upsets theSchrader valve when the swivel nut is almost tight, atwhich time the O-ring seal prevents agent loss. With theSchrader valve open, pilot cylinder pressure is applied to the normally closed solenoid valve and thepressure gauge. The pressure gauge provides for visual surveillance of the pressure condition withinthe cylinder. Where cylinders are located in areas not readily accessible for pressure gauge observation,or where supervision is a requirement, a supervisory pressure switch can be supplied as part of thesolenoid pilot valve assembly to continuously monitor the cylinder pressure and to transmit an alarmsignal in the event the pressure falls below an acceptable level.

2.1.5 Pressure Gauge Assembly

(Refer to Figure 2.1.5) In systems requiring morethan one cylinder, a pressure gauge assembly isrequired for each cylinder other than the pilotcylinder as a means of visual surveillance of thepressure condition within the cylinder. The assem-bly contains a swivel nut and O-ring seal forattachment to the gauge connection of the cylindervalve. A pin in the assembly upsets a Schradervalve when the swivel nut is almost tight, at whichtime the O-ring seal prevents agent loss. Thepressure gauge can be removed for replacementor checking without loss of agent since theSchrader valve closes as the gauge assembly isremoved.

Where cylinders are located in areas not readilyaccessible for pressure gauge observation, orwhere supervision is a requirement, a supervisorypressure switch can be supplied as part of thepressure gauge assembly. It can be used tocontinuously monitor the cylinder pressure and totransmit an alarm signal in the event the pressurefalls below an acceptable level.

2.2 Gamma System

(Refer to Figure 2.2) The Gamma System permitshigher discharge rates and is particularly adaptableto areas requiring larger quantities of FM-200 or discharges of short duration.

A description of the various equipment components unique to the Gamma System follows.

2.2.1 Cylinder Assembly

Gamma Series cylinders are available in four different capacities and are charged with FM-200 to afilling density from 35 lb/ft3 (561 kg/m3) to 70 lb/ft3 (1121 kg/m3) of cylinder volume. All cylinders aresuperpressurized with dry nitrogen to a pressure of 360 psig (2482 kPa) at 70F (21C). Each cylinderis equipped with an identification nameplate indicating the quantity of FM-200.

The standard cylinder assembly, having a rigid dip tube, is designed for mounting in a vertical positiononly. The cylinder assembly is composed of a cylinder, dip tube, and cylinder valve.

A. Cylinder: The steel cylinders are manufactured to the requirements of the Department of Transpor-tation (DOT) for compressed gas and have internal neck threads for cylinder valve connection.Each Gamma cylinder is provided with a boss to accommodate an optional liquid level locator orindicator. (The indicator must be installed prior to assembly of the cylinder components.)

Operating instructions and weight conversion charts for the use of liquid level indicators can befound in the Appendix.

Figure 2.2.1 - Gamma Cylinder Valve

B. Dip Tube: A threaded dip tube extends from the cylinder valve down to within approximately 1-1/2in. (38 mm) of the bottom of the cylinder. The steel tube has a 2-3/8 in. O.D. and 1/8 in. (3.2 mm)wall thickness. The threads are 2-3/8 in. 12UN-2A.

C. Cylinder Valve: A pressure release type cylinder valve having a forged brass body is attachedto the cylinder neck and serves to control the flow of FM-200 from the cylinder. The valve is securedto the cylinder by means of 4.5-12UN-2A screw threads and is sealed by a cylinder O-ring. Asynthetic rubber seat is attached to a steel seat retainer, which is screwed into the bottom of thevalve. The seat retainer also supports the dip tube.

The cylinder valve has six connections, as follows: (Refer to Figure 2.2.1)

1. Manual-Pneumatic Actuator Connection: This is a threaded connection housing a check valveand serves as the attachment point for the manual-pneumatic actuator.

2. Pressure Gauge/Solenoid Pilot Valve Assembly Connection: This is a threaded connectionhousing a check valve and serves for the attachment of:

a. Solenoid pilot valve assembly (with pressure gauge) for pilot cylinders.

b. Pressure gauge assembly for all other system cylinders.

3. Pneumatic Actuator Connection: This is a threaded connection housing a check valve locatedon top of the cylinder valve. It serves as an attachment point for the pneumatic actuators.

WARNING

IF THE PNEUMATIC ACTUATOR CONNECTION IS LOOSENED TO RELEASE PRESSURE FROM ABOVE THE MAINOPERATING PISTON, THE CYLINDER WILL DISCHARGE. NEVER ATTACH THE SOLENOID PILOT VALVE ASSEMBLYOR THE PRESSURE GAUGE ASSEMBLY TO THIS CONNECTION, AS THIS COULD CAUSE THE CYLINDER TO DISCHARGE.

PLEASE NOTE: THE PNEUMATIC ACTUATOR CONNECTION IS A THREADED INSERT [1/2 IN. (13 MM) NPT] IN THECYLINDER VALVE BODY, AND IS REPLACEABLE (PROVIDED CYLINDER IS EMPTY) IF FAULTY OR IF THE EXTERNALTHREADS ARE DAMAGED.

4. Safety Disc Connection: Two frangible safety discs are located on opposite sides and serve toprotect the cylinder against excessive internal pressure. The discs are designed to burst in a rangeof 850 psi to 1000 psi (5860 kPa to 6895 kPa).

5. Discharge Connection: This connection (2 in. nominal pipe size) (51 mm) is in the form of an outletfitting which threads into the valve body and is sealed with an O-ring. The exposed end is groovedfor attachment of grooved fittings (Victualic, etc). The outlet fitting can be removed for replacementis necessary.

2.2.2 Discharge Connection Fittings

A 2 in. (51 mm) grooved elbow, nipple, andcompanion coupling and gasket are used toextend the discharge outlet fitting of the cylindervalve to the piping system (refer to Figure2.2.2a).

These fittings ease assembly and accommo-date some minor differences in align-ment.

Check Valve

(Refer to Figure 2.2.2b) A check valve is used between thecylinder valve discharge outlet flexible connection and thedischarge manifold. The check valve prevents back flowfrom the manifold in the event that the system is dischargedwhen one or more cylinders are disconnected, such as forweighing or general servicing. A check valve is not requiredon single cylinder systems.

2.2.3 Pneumatic Actuator

(Refer to Figure 2.2.3) This device, attached to theconnection on top of the cylinder valve, is the finalstep in pilot operation to open the cylinder valve. Ithas a piston connected to a probe to upset theconnection check valve when pilot pressure isapplied to the piston. With the check valve open,pressure above the piston of the cylinder valve israpidly vented to atmosphere, thereby causing thecylinder valve to open. The pneumatic actuator isdesigned to reset automatically when pilot pressureis removed. The pneumatic actuator piston area tocheck valve area ratio is approximately 10 to 1.

2.2.4 Solenoid Pilot Valve Assembly

(Refer to Figure 2.2.4) The system utilizes a solenoid pilot valve assembly to provide pilot pressurefor actuation, whether system actuation is by automatic (detection device) or manual-electric(pushbutton) means.

The solenoid pilot valve assembly includes a pressure gauge and adapter with swivel nut, elbow, andO-ring seal that is attached to the pressure gauge connection of the cylinder valve. The adapter upsetsthe check valve when the swivel nut is almost tight, at which time the O-ring seal prevents agent loss.With the check valve open, pilot cylinder pressure is applied to the normally closed solenoid valveand the pressure gauge. The pressure gaugeprovides for visual surveillance of the pressurecondition within the cylinder.

Where cylinders are located in areas not readilyaccessible for pressure gauge observation, orwhere supervision is a requirement, a supervisorypressure switch can be supplied as part of thesolenoid pilot valve assembly to continuouslymonitor the cylinder pressure and to transmit analarm signal in the event the pressure falls belowan acceptable level.

Actuation of the solenoid pilot valve assemblypermits pressure to be applied through a flexibleconnector connected to the manual-pneumaticactuator, which in turn applies cylinder pressureto its operating piston.

A flexible electrical conduit is required for connection of the solenoid pilot valve assembly to the systemconduit. The flexibility facilitates removal of the assembly, as well as the cylinder, for servicing.

2.2.5 Pressure Gauge Assembly

(Refer to Figure 2.2.5) In systems requiring more thanone cylinder, a pressure gauge assembly is requiredfor each cylinder other than the pilot cylinder as ameans of visual surveillance of the pressure conditionwithin the cylinder. The assembly contains a swivel nutand O-ring seal for attachment to the gauge connectionof the cylinder valve.

When cylinders are located in areas not readilyaccessible for pressure gauge observation, orwhere supervision is a requirement, a supervi-sory pressure switch can be supplied as partof the pressure gauge assembly. It can be usedto continuously monitor the cylinder pressureand to transmit an alarm signal in the event thepressure falls below an acceptable level.

2.2.6 Bleeder Valve

(Refer to Figure 2.2.6) A bleeder valve is used in the pilot lineto prevent accumulation of pressure due to accidental leakagethrough a solenoid pilot valve assembly, which, if unvented,could cause a false discharge of the system. The valve isnormally open to atmosphere and closes at approximately 50psig (345 kPa) when full pilot pressure is applied during normalsystem operation. It is attached to the pneumatic actuator bymeans of a branch tee.

2.3 Beta/Gamma System

The components that follow are common to both the Beta and Gamma Series FM-200 Systems.

2.3.1 Manual-Pneumatic Actuator

` (Refer to Figure 2.3.1) This device is required for the manual actuation of a cylinder and is attachedto a check valve connection port. This is a dual purpose device, having an actuating piston connectedto a pin to upset the fill check valve when pilot pressure is applied to the piston. With the check valveopen, cylinder pressure is applied through the pilot connection to the operating piston of the Beta valveor the piston of the pneumatic actuator used on the Gamma valve, thereby opening the cylinder todischarge its contents.

A manual lever and cam arrangement on the actuator permits actuation of the device on a manualbasis, thereby overriding and independent of electric power or pilot pressure. A pullpin and seal preventsaccidental operation of the manual lever.

A swivel nut and O-ring seal on the device provides for attachment and seal at the connection point.

2.4 Beta System Operation

2.4.1 Cylinder Valve Operation

The Beta cylinder valve is designed to maintain cylinder pressure below the seat assembly (C) (Referto Figure 2.4.1). The pressure exerted by the spring (D) and the internal pressure forces a seal betweenthe elastomer in the seat assembly (C) and the machined seat ring in the cylinder valve (A). An O-ringin the bottom of the cylinder valve provides a seal between the cylinder valve and the threaded cylinderoutlet.

Figure 2.4.1 illustrates diagrammatically the two valve modes; namely standby, where the valve isawaiting actuation, and automatic actuation, where the valve has been electrically actuated by a firedetection control panel.

A. Standby

Pilot pressure is applied continuously to a normally closed solenoid pilot valve assembly. Thesolenoid pilot valve assembly is connected to the Schrader valve port (E) through a speciallymachined adapter fitting. A pressure gauge is part of the assembly to provide visual indication ofthe pressure in the container. In the standby mode, pressure is maintained below the seat assembly(C) and upstream of the seat of the pilot solenoid valve assembly (F).

B. Automatic Actuation

The solenoid pilot valve assembly is energized by the control panel output of the system, causingpressure to flow through a 3/16 in. flexible connector to the B port of the manual pneumatic actuator(H). The pilot pressure is applied to the piston of the manual pneumatic actuator (H), causing afill check (I) in the cylinder valve to upset, allowing a greater flow rate of pilot gas to the top of thecylinder head via a 3/16 in. flexible connector (G). The pressure fills the chamber, exerting pressureon the piston (B), causing the seat (C) to be pushed downward, allowing the FM-200 to flow aroundthe seat to the outlet of the cylinder valve. The manual-pneumatic actuator (H) keeps the cylindervalve open until the entire cylinder capacity is discharged.

2.5 Gamma System Operation

2.5.1 Cylinder Valve Operation

The valve is designed to have equal pressure both above and below the piston (A) in standby mode(Refer to Figure 2.5.1). The greater area of pressure exposure on top of the piston compared with thatbelow provides the force, in combination with the spring (B) force, to maintain the piston in sufficientcontact with the elastomer seat (C) to provide a tight seal. An O-ring (D) around the outer surface ofthe piston provides a seal between the piston and the valve body inner surface, thereby preventingleakage to the discharge outlet.

Cylinder vapor pressure is applied to the space above the piston through a filter (E) and ball check(F) at the base of the piston. The annular area around the stainless steel ball provides a limiting orificearea between the cylinder and space above the piston. The passage permits equalization of pressureabove and below the piston due to changes in cylinder pressure in response to ambient temperaturechanges. Flow through the passage under this condition is not sufficient to cause the ball to block thepassage.

Figure 2.5.1 illustrates diagrammatically the two valve modes, namely standby, where the valve isavailable for actuation, and automatic actuation, where the valve has been actuated electrically froma fire detection system.

A. Standby

In this mode, equal pressure exists above and below the piston. Pressure is exposed tot he solenoidvalve and pressure gauge of the solenoid pilot valve assembly (G). Pressure is also exposed tothe seat of the fill check valve (I) related to the manual-pneumatic actuator (H) and pneumaticactuator (J). The outlet of the solenoid valve is connected by a 3/16 in. flexible connector (K) tothe B port of the manual-pneumatic actuator. The A port of the manual-pneumatic actuator isconnected to the pneumatic actuator by another 3/16 in. flexible connector (L).

B. Automatic Actuation

The solenoid pilot valve assembly is energized by the system detection control panel output, causingit to open and apply pressure through port B of the manual-pneumatic actuator (H). This, in turn,applies pilot pressure to the piston of the manual-pneumatic actuator (H), causing a fill check (I)in the cylinder valve to upset, allowing a greater flow of pilot gas. With the check valve open, cylinderpressure from port A is applied to the piston of the pneumatic actuator (J) at the top of the cylindervalve. This pressure forces the pneumatic actuator piston down so that its probe unseats the checkvalve (I), which results in venting pressure rapidly from above the piston of the cylinder valve.Reduced pressure above the piston enables cylinder pressure below the piston to force the pistonup, resulting in discharge of agent from the cylinder. Complete evacuation of the cylinder dependson a raised piston, which requires maintaining a reduced pressure above the piston. The manual-pneumatic actuator locks itself in actuation mode once it is actuated, either pneumatically by thesolenoid pilot assembly or manually by its own actuation lever.

The bleeder valve (M) insures that slight leakage at the seat of the solenoid will not build up in thepneumatic actuator and cause an unintentional operation of the pneumatic actuator.

3 SYSTEM DESIGN

The information contained in this section covers the design of engineered systems.

The inlet and outlets of the tee branches must be in the same horizontal plane to avoid an imbalancefrom the gravitational effects of the liquid and vapor separation.

The design of the system consists of selection and proper placement of the following equipment:

Container(s)Mounting bracket(s)Nozzle(s)Pipe and fittingsControl panel(s)DetectionOptional accessories

Proper FM-200 system design requires completion of the following seven steps to determine theselection, placement and installation of the containers, mounting brackets, nozzle(s), pipe and fittings.Selection and placement of the alarm and control devices are discussed in other publications.

3.1 Step 1 - Agent Requirement

The first step in designing an FM-200 total flooding system is to determine agent weight requirementsfor the desired concentration in the area(s) protected. The minimum design concentration for a ClassA surface fire hazard shall be the extinguishing concentration times a safety factor of 1.2. A minimum6.25% volumetric concentration is required for Class A surface burning type fires, such as wood orother cellulose type materials. The Class B flammable liquid type fires require a minimum designconcentration at 30% above the extinguishing concentration of the fuel or 30% above the cup burnervalue established for the fuel. Design values for particular fuels are given in the Appendix of this manual.The minimum design concentration for Class C hazards shall be at least that for Class A surface firesand the minimum design concentration for a manually actuated system shall be the extinguishingconcentration times a safety factor of 1.3. The agent concentration should be based on the lowestambient temperature expected within the area. When calculating the concentration levels for normallyoccupied spaces, care must be taken to insure that at its highest expected ambient temperature, thespace does not exceed the NOAEL value of FM-200 of 9% as stated in National Fire ProtectionAssociation Standard 2001.

To determine the agent required for any space for a specific concentration, the volume of the areamust be known. Any environmental factors that require additional agent for compensation, such astemperature and leakage, also must be known. By using the agent factor from Appendix Tables AP-1or AP-2, or weight requirement formula, we can determine the quantity of FM-200 for any space volumeand select the required equipment. Volume is defined as the capacity of an area and can be foundby multiplying its length x its width x its height. Volume = (L x W x H).



S/N 30000030


The amount of FM-200 required to achieve the design concentration at a specific temperature canbe calculated from the following formula.

Where: W = Agent weight in poundsV = Hazard volume in cubic feetC = FM-200 Agent volumetric concentration, percent by volumes = Specific vapor volume in cubic feet/pounds

s = 1.885 + (0.0046 x T), where T = temperature F

Therefore: s = 1.885 + (0.0046 x 70) = 2.207

Using the formula above (a 6.25% design concentration for a 22,150 cubic foot room at 70F), theequation would look like this:

-Or-

Example: To determine the FM-200 agent required to provide a 6.25% concentration using tablesAP-1 or AP-2, the factor is matched from the temperature required. In our example, theroom temperature is 70F; using table AP-1, our factor is 0.0302. The volume is multipliedby this factor to determine the amount of FM-200 required for our 6.25% concentration.

22,150 cu.ft. X 0.0302 lbs/ft = 668.93 lbs.3
