AGENT QUANTITY AND CYLINDER SELECTION:
After reviewing the hazards and determining the number and type of nozzles that will be required, the quantity
of agent and the number and type of cylinders must be selected. Adding the number of flow points that are
needed for the system will determine the agent quantity and cylinder options.
a.
ONE 2.75 GALLON CYLINDER
(P/N 16921)
WILL SUPPLY SUFFICIENT AGENT FOR UP TO
AND INCLUDING 8 FLOW POINTS.
b.
ONE 3.75 GALLON CYLINDER
(P/N 13334)
WILL SUPPLY SUFFICIENT AGENT FOR UP TO
AND INCLUDING 11 FLOW POINTS.
c.
ONE 4.75 GALLON CYLINDER
(P/N 17379)
WILL SUPPLY SUFFICIENT AGENT FOR UP TO
AND INCLUDING 14 FLOW POINTS.
Cylinders may be used together for multiple cylinder systems with one MRM
,
MRM II or PRM. A
MAXIMUM OF 10 KP 275/375/475 AGENT CYLINDERS MAY BE USED PER MECHANICAL RELEASE
MODULE OR PNEUMATIC RELEASE MODULE.
d.
ONE 6.14 GALLON CYLINDER (
P/N 15196
) WILL SUPPLY SUFFICIENT AGENT FOR UP TO
AND INCLUDING 18 FLOW POINTS.
A MAXIMUM OF 6 KP 600 AGENT CYLINDERS MAY BE USED PER MRM
,
MRM II or PRM. ANY
COMBINATION OF CYLINDERS INVOLVING THE KP600 CYLINDER IS LIMITED TO A TOTAL OF 6
CYLINDERS PER MRM, MRM II or PRM.
ACTUATION NETWORK LIMITATIONS – MRM, MRM II OR PRM
The actuation network for the Amerex Restaurant Fire Suppression System consists of factory supplied hose;
installer supplied copper tubing or pipe that connects the MRM, MRM II or PRM to each cylinder discharge
valve. A single MRM, MRM II or PRM 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).
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.
