CAUTION
Install EMA(s) as the first component(s) on the Detection Circuit
and on a single use branch. Failure to comply may cause the
system to not function properly. (see Figure 4-9, and 4-10).

Release Circuit Cable (Blue Connectors)
Connects Electric-Pneumatic Actuator(s) (for agent tank expel-
lant gas cartridges(s)) to CHECKFIrE 110 Control Module.
• system activates a maximum of 2 Electric-Pneumatic Actua
-
tors (one per tank).
• For electrical actuation 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 two actuators.
• 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 list on page 2-2.
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 control
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 possi

ble from vehicle 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 vehicle service and mainte

3. Select appropriate cable lengths for area of installation.
see section 2 - Components, page 2-5, for available sizes.
Maximum 50 ft (15.2 m) allowed.
4. If more than one Electric-Pneumatic Actuator is required,
add a release Circuit Tee and appropriate length release
Circuit Cable to interconnect release circuits.
