agent and consisting of four basic components and their associated accessories FM 200 Components Control Panels Detection and Alarm Devices Completer Kits Features TheFM 200componentsconsistofagentcontainers 1 container supports racks and discharge nozzles The control panel is the brains of the system and is 2 used to monitor the detection and accessories Thedetection alarmdevices andaccessoriesare the 3 externaldevicesthatactastheeyesand voice of the system as they give audible or visual signals The completer kits consist of warning signs hoses 4 connection fittings pressure gauges or solenoid valves and the actuator required to operate the cylinder valve Thesystemanditscomponentsareagencytestedfortotal flooding applications and should be used in accordance withthe guidelines contained in National Fire Protection Association2001 Atotal flooding application can be de fined as injecting FM 200 into an enclosure or volume having the structural integrity to retain the agent during andafterdischarge Thedesignof such a system requires that the FM 200 chemical agent be discharged from its container within 10 seconds and be thoroughly mixed throughout the protected volume reaching a minimum concentration level of 7 but not exceeding 9 in normally occupied spaces GAMMA SERIES SYSTEM EQUIPMENT DESCRIPTION TheGammaSystempermitshigher

consists of carbon fluorine and hydrogen It is colorless odorless electrically non conductive and suppresses fire by interruptingthecombustionprocess 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 any downtime after a fire If exposed to temperatures greater than 1300 F toxic products ofdecomposition hydrogenfluoride areformed The system is designed to discharge in 10 seconds or less to minimize the amount of toxic byproduct formed during extinguishment of flames
