TESTING FOR GROUND FAULT
After all detectors have been wired into the control panel and you are performing a final
check of the panel, use this procedure for a ground fault test:
• Monitor Card with Ground Fault Indicator Test Switch:
o Disconnect chassis ground from Terminal #4 on the power card.
o Push the Ground Fault Indicator (GFI) Test Switch on the Alarm Monitor Card.
o Release the Test Switch and re-connect chassis ground to Terminal #4 on the
Power Card.
• Monitor Card without Ground Fault Indicator Test Switch:
o Disconnect chassis ground from Terminal #4 on Power Card.
o Connect a jumper between Terminal #1 and Terminal #2 on the Alarm Monitor
Card.
o Disconnect the jumper between Terminal #1 and Terminal #2 on Alarm Monitor
Card.
o Reconnect the chassis ground to Terminal #4 on the Power Card.
NOTE: If there is a ground in the system, the amber Ground Fault Indicator LED (GDF)
will light on the Alarm Monitor Card. There will be no beeper sound.
If there is not a ground in the system, because there is no trouble signal the amber Ground
Fault Indicator LED (GDF) on the Alarm Monitor Card will not light.
