Detection and Actuation System
TABLE 9-4: MULTIPLE CIRCUIT FAULTS
Multiple Circuit Faults
Detection Circuit Fault, Release Circuit Fault, “PUSH to
Activate / Alarm When Lit” LEDs, and Sounder pulsing 1 x
10 seconds indicate Post Discharge Mode, Detection Circuit
fault, and/or Release Circuit fault.
When multiple fault conditions exist, check each circuit as
previously described (clear circuit faults in this order: Power,
Release, Detection). Determine fire system status.
• Check connections on all cables
• Check Release Circuit Cables for an open circuit or a
ground fault; replace cables as needed
• Check Detection Circuit Cables for an open circuit or a
ground fault; replace cables as needed
• Check for activated or missing PAD(s); replace as needed
following Section 8 – Recharge instructions
Note: The Power LED could also be pulsing AMBER if there
is a fault in the External Power Circuit.
TABLE 9-5: SPECIFIC CIRCUIT TESTING PROCEDURES
General Instructions
Test the connecting cables if faults are indicated on the
CHECKFIRE 110 Control Module, and end of circuit devices
(EMAs, EOL Device, branch terminators, PADs, etc.) are
properly connected to the system.
Before testing specific circuits, confirm completion of a thor-
ough visual inspection. Inspect all cables for damage and
replace if there are visible and mechanical signs of damage
(brittleness, deformation, discoloration, etc.). Test all connec-
tions for loose or disassembled connectors.
Note: Once all faults are cleared, confirm proper operation of
the entire CHECKFIRE 110 System by completing Section 6 -
Test and Place in Service.
If faults cannot be cleared, test each circuit and cable individ-
ually with the following procedures.
