Detection and Actuation System
Detection Circuit (Continued)
4. If Detection Circuit #1 fault does not clear, continue
testing the detection circuit at each set of connectors
starting at the next connection point from the ICM. Sepa-
rate connectors and install EOL Device or DCT 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 new component (cable, tee, EMA, etc.) at
a time to help identify the specific part causing the
fault.
5. At a Detection 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 Branch Termi
-
nator on branch side of tee, and the EOL Device or DCT
on main trunk side. If fault clears tee is good; if fault does
not clear replace tee.
6. After checking a Detection Circuit Tee, continue testing
components to the end of the branch line.
If a non-functioning component is found and replaced on
a branch line, reconnect the complete detection circuit to
determine if that is the only fault in the circuit.
If reconnecting the remaining detection circuit causes
a fault, return to the last connection that was good and
continue testing the main trunk and any branch lines in
the same manner until detection circuit fault clears.
Cancel Isolate mode by returning the Isolate switch to the
normal position.
If all faults are clear, verify proper operation of the
CHECKFIRE 210 System by completing Section 6 –
Operational Test and Place in Service.
When Detection Circuit #2 is part of the system, troubleshoot
and correct faults on Detection Circuit #2 in a similar manner
to those described above.
Note: Specific jurisdictions or customer procedures may
require documentation of all components replaced. Keep a
record of all changes to the system as required.
