Amerex Restaurant Fire Suppression System
(EX 4658)
INSTALLING THE ACTUATION NETWORK, STRIKE™ Releasing Module (SRM)
The SRM is used in conjunction with the STRIKE™ ECS and is for UL Certification only and
cannot be considered for or used in installations of KP/ZD systems in Canada.
Refer to the Design section for limitations of the Actuation Network. Piping for the actuation network
can be ¼” black, chrome plated, galvanized schedule 40 pipe, copper tubing or hose. The network
originates at the pipe outlet of the SRM and continues to the top of each cylinder and valve
assembly. The protective plug on each cylinder valve must be removed. All pipe used for the
actuation network must be reamed and blown clear, mounted to a sufficient structure, adjusted for
level and plumb and fastened in an appropriate manner. Pipe must be fitted
tight (three turns past
hand tight recommended). All threaded connections in the actuation network must be sealed
with Teflon tape (applied to male threads only). Starting with the third thread from the pipe
opening, wrap the Teflon tape clockwise around the threads moving away from the pipe
opening. Make certain that tape does not extend past the end of the pipe – it could dislodge
and possibly block the actuation network.
CAUTION: Do not over tighten the pipe or pipe fittings into the pipe threads on the SRM. Over
tightening can cause the SRM to malfunction.
A single SRM will actuate a maximum of ten (10) agent cylinders. The ten cylinders may be
any combination of 275, or 375, or 475 Agent Cylinders. When a 600 is included in the mix of
agent cylinders the total maximum allowable agent cylinders is lowered to six (6). Outlined
on page 3
-
29a are the maximum amounts of pipe, hose or tubing allowed in the actuation
network. When a network consists of more than one of the media listed, the total allowable
footage is equal to the smallest of the two media limits.
EXAMPLE: An actuation system made up of black pipe and hose would limit the total footage
of pipe plus hose to 22.2 feet.

Note:
A vent plug (P/N 10173) must be
used and placed in an accessible location
anywhere in the actuation network to aid in
relieving pressure after system discharge,
and to keep pressure from building slowly in
the network.
