ECS Series Engineered Fire Suppression Systems
4-2.4 Other Conditions
4-2.4.1 OPERATING/STORAGE TEMPERATURE
RANGE
Kidde FM-200 ECS Series Engineered Fire Suppression
System equipment listed herein is designed to operate within
a temperature range of 32°F to 130°F (0°C to 54°C). The
Kidde ECS Series FM-200 Flow Calculation Program as-
sumes a temperature of 70°F (21°C). Therefore, the con-
tainer operating and storage temperature must be in the
range of 60°F to 80°F (16°C to 27°C) for a single unbal-
anced system protecting two or more separate hazards. If
the container operating/storage temperature is outside this
range, an insufficient quantity of agent may be discharged
from one or more discharge nozzles.
4-2.4.2 STORAGE TEMPERATURE
Kidde FM-200 ECS Series Engineered Fire Suppression
System equipment is suitable for storage from 32°F to 130°F
(0°C to 54°C).
4-2.4.3 SYSTEM OPERATING PRESSURE
The normal system operating pressure for Kidde FM-200
ECS Series Engineered Fire Suppression System equip-
ment is 360 PSIG at 70°F (25 bar gauge at 21°C).
4-2.5 Pressure Actuation Limitations
Four modes of pressure actuation of the Kidde FM-200
ECS Series Engineered Fire Suppression Systems cyl-
inders are available.
Note: When cylinders are all connected to a common
manifold, they shall be at the same size and
fill density.
4-2.5.1 CYLINDERS CLOSE COUPLED USING
PRESSURE FROM A MASTER
Note: See Figure 4-5.
For cylinders close coupled (reach of one flex hose, max.
30 in.) using pressure from one master FM-200 cylinder, a
maximum of fifteen slave cylinders close coupled can be
actuated from that one master cylinder, using pressure op-
erated control heads on the slave cylinders. The slave cyl-
inder operation will be through pilot flexible hoses.
4-2.5.2 CYLINDERS NOT CLOSE COUPLED
USING PRESSURE FROM A MASTER
Note: See Figure 4-6.
For cylinders not close coupled using pressure from one
master FM-200 cylinder, a maximum of four slave
cylinders (maximum five cylinders in a group) can be actu-
ated by that one master cylinder using pressure operated
control heads on the slave cylinders. The slave cylinder
operation will be through a 5/16" O.D. x 0.032" wall copper
tubing actuator line having a maximum total length of
100 ft. (30.5 m).
4-2.5.3 CYLINDERS NOT CLOSE COUPLED
USING NITROGEN PRESSURE
Note: See Figure 4-7.
For cylinders not close coupled using nitrogen pressure
from one pilot nitrogen cylinder, from one to fifteen slave
FM-200 cylinders can be actuated from the one pilot nitro-
gen cylinder using pressure operated control heads on the
slave cylinders.
Slave operation will be through a 5/16 O.D. x 0.032"
wall stainless steel tubing actuator line having the
following limitations:
Maximum total length of tubing is 320 ft. (97.5 m).
Maximum length of tubing between cylinder #1 and
the last cylinder is 220 ft. (67 m).
The nominal min./max. length of tubing between
the nitrogen pilot cylinder and FM-200 cylinder #1
is up to 100 ft. (30.5 m).
If required, the nitrogen pilot cylinder can be lo-
cated at a distance greater than 100 ft. (30.5 m)
from FM-200 cylinder #1. In this instance, tubing
length can be taken from the line between the
slave cylinders and added to the line between
the nitrogen cylinder and slave cylinder #1, pro-
vided that the maximum total length of tubing
does not exceed 320 ft. (97.5 m).
The tubing actuation line must be designed for a
minimum working pressure of 1800 PSIG
(124 bar gauge).
