Amerex Restaurant Fire Suppression System
(EX 4658)
Actuation Network Limitations, 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.
The actuation network for the Amerex Restaurant Fire Suppression System
consists of factory supplied hose; installer supplied copper tubing or pipe that
connects the SRM to each cylinder discharge valve. A single SRM is capable of
actuating up to ten (10) 2.75 / 3.75 / 4.75 gallon agent cylinder discharge valves
or six (6) 6.14 gallon agent cylinder discharge valves by discharging a single 10
in
3
nitrogen cylinder (P/N 12856) through the actuation network. If the network is
a combination of any of the 2.75, 3.75 and or 4.75 with a 6.14 gallon cylinder,
then maximum number of cylinders is six (6).
Note:
A vent plug (P/N 10173) must be placed in an accessible location
anywhere in the actuation line to aid in releasing pressure after the system
has discharged. See the RECHARGE Section 7.
LIMITATIONS (SINGLE OR MULTIPLE CYL SYSTEMS)
Copper tubing
– ¼” O.D. refrigeration type with a
minimum wall thickness of .049 inches. Use with
brass or steel compression style fittings (with brass
or steel sleeves or ferrules). Maximum length
(including all fittings) 100 feet (30.48 m)
High Pressure Hose
– ¼” I.D. wire braid hose that
is factory supplied. Maximum length (including all
fittings) 54 feet (16.46 m) or a maximum number of
40 hose assemblies P/N 12854, 20 hose
assemblies P/N 16448, or any combination that
does not exceed a total of 54 feet (16.56 m)
Pipe
– ¼” NPT schedule 40 made of stainless
steel,
galvanized, chrome plated or black iron pipe:
Maximum length – 22.2 feet (6.77m)
Maximum tees – 9
Maximum elbows – 9 (note: 2 – 45° elbows = 90°)
Note: Different methods of constructing the
actuation network may be mixed provided that the
shortest limitations are followed,
Example: A mix of ¼” copper tubing and ¼” high
pressure hose requires that the hose limitations be
followed (no more than 54 feet [16.46m]) for the
complete network. A mix of ¼” high pressure hose
and ¼” pipe requires that the pipe limitations be
followed (no more than 22.2 feet [6.77m]) for the
complete work.
