Release Circuit (Continued)
2. If Release Circuit Fault clears, the CHECKFIRE 110
Control Module is functioning properly. Re-install complete
release circuit to the control module release circuit lead
and complete an SDR (Self Diagnostic Routine: Press and
hold “DELAY/Reset/Silence” button for 3 seconds; Power
LED and Sounder quickly pulse 3 or 5 times, then Power
LED remains GREEN steady-on).
3. If Release Circuit Fault does not clear, continue testing
the release circuit at each set of connectors starting at the
next set from the control module. Separate connectors and
install Release Circuit Terminator on control module side.
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 new component (cable, tee,
etc.) at a time to help identify the specific part causing
the fault.
4. 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.
5. After checking a Release Circuit Tee, continue testing
components to the end of the drop line.
6. To test the Release Circuit Drop Cable at the end of a
drop or end of the main trunk, reconnect cable to the
original location. If there is no fault indication, the Release
Circuit Drop Cable and PAD are working properly.
7. If the Release Circuit Drop Cable causes a fault, remove
cable from the Electric-Pneumatic Actuator and replace
the PAD with the Release Circuit Test Plug.
If the fault clears, replace the PAD.
If the fault continues, replace the Release Circuit Drop
Cable.
