Display Cable (Black Connectors)
Connects Display Module to CHECKFIRE 210 ICM.
• Communicates commands, and system status with ICM
• No tees or branch lines on this circuit
• Only one display module allowed for each CHECKFIRE 210
System
1. Determine location of display module for specific cable
end points.
2. Plan route for the display cable from the ICM to the
display module end point (note end points for cable
lengths). Choose a path in accessible locations providing
protection from undue wear, damage, and heat. Keep
cables as far away as possible from equipment electric
cables, particularly power cables to and from generators
and electric motors; also avoid:
• Antennas and associated cables
• Fire hazard areas
• Areas exposed to mechanical damage
• Proximity to moving parts
• Areas subject to debris accumulation
• Areas exposed to high temperatures (turbo chargers,
exhaust equipment, etc.)
• Areas requiring access by equipment service and main
-
tenance personnel
3. Select appropriate cable lengths for area of installation.
See Section 2 - Components, page 2-2, for available
sizes. Maximum circuit length is 50 ft (15.2 m).
Release Circuit Cable (Blue Connectors)
Connects Electric-Pneumatic Actuator(s) (for agent tank expel-
lant gas cartridges(s)) to CHECKFIRE 210 ICM.
• System activates a maximum of 10 Electric-Pneumatic Actu
-
ators (one per tank).
• For electrical activation include a Release Circuit Drop Cable
and a Protracting Actuation Device (PAD) (Part No. 439448)
for each actuator. Release Circuit Tee (Part No. 439434)
required for each additional actuator.
• For optional pneumatic actuation install a pneumatic manual
actuator near the operator and/or in path of egress at a point
accessible from ground level. Refer to appropriate system
manual (latest edition):

1. Determine location of agent tank(s), expellant gas
cartridge assembly(s), and actuator(s) for specific cable
end points.
2. Plan route for the release circuit cable from the ICM
module to the agent tank expellant gas cartridge end
point(s) (note end point(s) for cable lengths). Choose a
path in accessible locations providing protection from
undue wear, damage, and heat. Keep cables as far away
as possible from equipment electric cables, particularly
power cables to and from generators and electric motors;
also avoid:
• Antennas and associated cables
• Fire hazard areas
• Areas exposed to mechanical damage
• Proximity to moving parts
• Areas subject to debris accumulation
• Areas exposed to high temperatures (turbo chargers,
exhaust equipment, etc.)
• Areas requiring access by equipment service and main

tenance personnel
3. Select appropriate cable lengths for area of installation.
See Section 2 - Components, page 2-9, for available
sizes. Maximum 250 ft (76.2 m) allowed.
4. If more than one Electric-Pneumatic Actuator is required,
add a Release Circuit Tee and appropriate length Release
Circuit Cable for each additional actuator.
