TABLE 9-5: SPECIFIC CIRCUIT TESTING PROCEDURES (Continued)
Detection Circuit (Continued)
3. If Detection Circuit Fault does not clear, continue testing
the detection circuit at each set of connectors starting at
the next set from the control module. Separate connectors
and install EOL Device or DCT 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,
EMA, etc.) at a time to help identify the specific part
causing the fault.
4. 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 Termina
-
tor 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.
5. After checking a Detection Circuit Tee, continue testing
components to the end of the branch.
If a non-functioning component is found and replaced on a
branch and the entire branch is not causing a fault, recon-
nect 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.
If all faults are clear, verify proper operation of the
CHECKFIRE 110 System by completing Section 6 – Test
and Place in Service.
Note: Specific jurisdictions or customer procedures may
require documentation of all components replaced. Keep a
record of all changes to the system as required.
3. IF FAULT CONTINUES
TEST EACH
CONNECTION, REPLACE
COMPONENTS AS
NEEDED
5. IF FAULT IS CORRECTED IN BRANCH
LINE, RECONNECT ENTIRE CIRCUIT;
IF FAULT OCCURS, CONTINUE
TESTING CIRCUIT FROM LAST GOOD
CONNECTION UNTIL FAULT CLEARS
4. AT TEE TEST MAIN TRUNK
CONNECTION FIRST
THEN INSTALL BRANCH
TERMINATOR AND
EOL DEVICE (OR DCT)
