SYMPTOM
PROBABLE CAUSE
CORRECTIVE ACTION
Component not connected or
damaged harness in gas
detection circuit
Check gas detectors’ LED
indicators. If any are not
illuminated this is an
indication that power is not
being received.
Check harness connections at
the gas detectors.
Check for the correct voltage
values on the gas circuit. (Pin
A: 22-26 volts, Pin B: Ground,
Pin C: 11-15 volts).
NOTE: The gas detectors will
not be powered if Pin B is not
equal to Ground.
If the voltage at Pin A or C is
low, use an EOL and starting
at the first connection in the
gas circuit systematically
check the voltage at each
connection until the section
where the fault exists is
identified.
