Fire and Gas Fault Alarm
FGP-AI420LO Doesn't distribute 24 Vdc to both of Gas Detector at house filter and heavy duty

In our Fire&gas Promel System the fault alarm is detected we follow the wiring diagrams. we find FGP-AI420LO doesn't distribute 24 Vdc to both of Gas Detector at house filter and heavy duty in GE 5001 GAS TURBINE.
>>> all the other gas detectors have a normal power 24vdc.

Is this normal situation or should to replace the FGP-AI420LO from the system?
