Introduction
The Cerberus Pyrotronics Model FM-350 and FM-500 are
large capacity FM-200TM storage containers with 2½ inch
discharge valves. The FM-350 and FM-500 have a capacity
of 350 or 500 lbs of FM-200TM. The FM-350 and FM-500 are
capable of local or remote manual operation, electric
operation, pneumatic operation or a combination of a
manual and pneumatic operation. The FM-350 and FM-500
cylinder assemblies are designed to meet the requirements
of UL 1058 and are ideally suited for use in all large com-
mercial and industrial hazards.
Technical Description
The FM-350 and FM-500 can be filled with a maximum of
350 or 500 lbs. of FM-200TM and pressurized with nitrogen
to 360 psig at 70°F.
The cylinders are operated by the relief of pressure above
the valve piston which permits the valve piston to travel
upward thus fully opening the valve and permitting the FM-
200TM to discharge through the outlet which is located at
the top of the valve.
The FM-350 and FM-500 can be actuated by one of the
following means:
1. Electric Solenoid Valve — The solenoid valve is
normally closed and opens upon electric energy being
applied, thus relieving the pressure above the valve piston
and causing the cylinder valve to open. The solenoid valve
has a swivel nut for a mechanical connection to the cylinder
valve. For electrical connection it is furnished with 18 inch
pigtails which are fed through flexible metallic conduit to
allow convenient removal of the solenoid valve from the
cylinder valve when servicing.
2. Local Manual Control Head — moving the actuat-
ing lever through 90° causes a pin to depress and open the
pilot check on the valve and releases FM-200TM pressure
above the valve piston.
3. Remote Manual Control Head — Same Actuation
as the local manual, except the lever is controlled by a 1/16
inch diameter stainless steel pull cable enclosed in ½ inch
E.M.T. with corner pulleys at each change of direction. The
cable terminates in a remotely located pull box.
4. Pressure Actuator — The pressure actuator replaces
the local and remote control heads on the valve. It contains
a piston of sufficient area to provide the necessary force to
open the pilot check when pressure from the FM-200TM
discharge of a master cylinder is applied through 5/16 inch

copper tubing or 5/16 inch actuation hose. The pressure
actuator is used on pressure operated (slave) cylinders
which are to be released simultaneously with the control
(master) cylinder.
One master cylinder can be used to pressure operate up to
a maximum of four slave cylinders. If more than five cylin-
ders are required up to 15 may be pressure operated using
a nitrogen pilot cylinder.
All cylinder valves have a pressure actuation outlet port
which is under pressure only while the valve is discharging.
The port has a 1/8 inch pipe thread and is fitted with a pipe
plug, which is removed when the port is to be used, and
replaced with a master cylinder adapter kit. The tubing or
actuation hose is connected to the adapter kit and run to
the pressure actuators on the slave cylinders.
The pressure operating tubing in a multi-cylinder fire
extinguishing system can be supervised with the use of the
model CSS cylinder supervisory switch.
5. Combination Pressure Actuator and Manual
Control — A special pressure actuator is also available to
which either a local or remote type manual control head
can be attached. It is used when both pressure actuation
and manual control is required for the same cylinder.
These steel cylinders are manufactured and tested in
accordance with D.O.T. specifications; 4BW500. The FM-
350 and 500 lb. cylinders are fitted with 2 lifting lugs for
convenience of handling.
The 2½ inch brass discharge valve can be piped or
connected to the piping or manifold via the 2½ inch flexible
discharge hose.
Cylinder bracketing expressly designed for the FM-200TM
cylinder is available for mounting directly onto a wall or with
optional mounting channels.
The FM-500L, 350L and 200L comes equipped with a liquid
level indicator for easy determination of the weight of the
FM-200TM in the cylinder.
Architect/Engineers Specification
The FM-200TM storage container shall be capable of
holding 350 or 500 lbs. of FM-200TM and be pressurized
with nitrogen at 360 psig at 70°F.
The FM-200TM cylinders shall be operated by the relief of
pressure above the valve piston. The valve shall be actu-
ated by local or remote manual operation, electric opera-
tion, pneumatic operation or as combination of a manual
and pneumatic operation.
On pneumatically operated systems, one master cylinder
shall be capable of operating up to 4 slave cylinders if
desired.
If desired, the pressure operated multi- FM-350 or FM- 500
cylinder fire extinguishing system shall be supervised by
the model CSS Cylinder Pressure Supervisory Switch.
The system shall be capable of either being piped or
connected to piping via a 2½ inch flexible discharge hose.
If desired the FM-200TM container shall come equipped with
a liquid level indicator to determine the weight of FM-200TM
in the container.
The FM-200TM container and system shall be listed by
Underwriters Laboratories and approved by Factory
Mutual.
