rELEASE CIrCUIT CABLES (Continued)
Install Release Circuit using the following rules (see Figure
5-43 and 5-44):
1. Maximum ten PADs.
2. Maximum length is 250 ft (76.2 m) of Release Circuit
Cable. (Cable dimensions include the connectors.)
3. Use a Release Circuit Tee for each additional actuator.
Additional Release Circuit Cable may be used after the tee
if required.
4. Use Release Circuit Drop Cable at end of circuit for
connection to the Electric-Pneumatic Actuator.
5. Route and secure Release Circuit Cable following instal-
lation instructions under Cable Connectivity / Installation,
page 5-5. (Remove and discard dust cap on Release
Circuit Receptacle.)
6. Do not attach Release Circuit Drop Cable to Electric-Pneu-
matic Actuator at this time. If Release Circuit Drop Cable
is connected, the system could be accidentally actuated
during installation.
CAUTION
DO NOT ATTACH ANY RELEASE CIRCUIT DROP CABLE
TO ANY ELECTRIC-PNEUMATIC ACTUATOR UNTIL
TESTING IS COMPLETE.

rELAY CIrCUIT CABLES
The Relay #1 & #2 Output Receptacle (yellow ID ring) on the
CHECKFIRE 210 ICM is the starting point for the relay circuits.
Each circuit provides connection points to contacts for two
internal SPDT Form C relays. See Figure 5-45. The relays
can be used to activate external notification devices or provide
inputs to vehicle/equipment onboard monitoring systems.
Connections to vehicle/equipment components are made by
others.
Contact Rating for both relays: 30 VDC nominal at 6 amps.
