6. If Release Circuit fault clears, the ICM is functioning
properly and the fault is in the cabling or connectors.
Re-install complete release circuit to the ICM Recepta-
cle. Reset to Normal: Press and hold “DELAY/Reset/
Silence” button for 3 seconds; Green and Red LEDs are
steady-on for 1 second; then Amber LEDs are steady-on
for 1 second; at end sounder quickly pulses 3 times.
7. If Release Circuit fault does not clear, continue testing the
release circuit at each set of connectors starting at the
next connection point from the ICM. Separate connec-
tors and install Release Circuit Terminator at the end of
the cable connected to the ICM. If fault does not clear,
replace non-functioning component with an identical new
part and retest. If fault clears, part is good; re-install and
move to next set of connectors. Note: Be sure to add
only one additional component (cable, tee, etc.) at
a time to help identify the specific part causing the
fault.
8. At a Release Circuit Tee remember to first check the
main trunk connector leading to the tee; then re-connect
to check the tee. Install a Detection Circuit Terminator on
each side of tee. If fault clears tee is good. If fault does
not clear replace tee.
9. After checking a Release Circuit Tee, continue testing
drop line to the end of the Release Circuit Drop Cable.
10. Test Release Circuit Drop Cable using a Release Circuit
Test Plug. If the Release Circuit Drop Cable causes a
fault, replace it with an identical new part and retest.

7. IF FAULT CONTINUES,
TEST EACH CONNECTION,
REPLACE COMPONENTS
AS NEEDED
8. AT TEE, TEST
MAIN TRUNK
CONNECTION FIRST
8. THEN INSTALL
TERMINATORS ON DROP AND
MAIN TRUNK CONNECTORS
6. IF FAULT CLEARS,
RECONNECT AND RESET
TO NORMAL
9. AFTER TEE, CONTINUE
