GENERAL INFORMATION
The Chemetron Fire Systems Gamma Series Systems are
automatic suppression systems using the FM-200 chemi-
cal agent and consisting of four basic components and
their associated accessories.
FM-200 Components
Control Panels
Detection and Alarm Devices
Completer Kits
Features
The FM-200 components consist of agent containers,
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.
The detection, alarm devices, and accessories are the
3
external devices that act as the eyes and 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.
The system and its components are agency tested for total
flooding applications and should be used in accordance
with the guidelines contained in National Fire Protection
Association 2001. A total flooding application can be de-
fined as injecting FM-200 into an enclosure or volume
having the structural integrity to retain the agent during
and after discharge. The design of 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
The Gamma System permits higher discharge rates and is
particularly adaptable to areas requiring larger quantities
of FM-200. A description of the various equipment com-
ponents unique to the Gamma System follows.
Cylinder and Valve Assembly
Gamma Series cylinders are available in
four different capacities and are
charged with FM-200 to a filling densi-
ty up to 70 lb/ft (1121 kg/m ) of cylin-
3
3
der volume. All cylinders are super-
pressurized with dry nitrogen to a
pressure of 360 psig (2482 kPa), at
70°F (21°C). Each cylinder is equipped
with an identification nameplate indi-
cating the quantity of FM-200.
The standard cylinder assembly, hav-
ing a rigid dip tube, is designed for
mounting in a vertical position only.
The cylinder assembly is composed of
a cylinder, dip tube, and cylinder
valve.
