Troubleshooting
The following are common methods to solving Circuit Troubles, Ground Fault, Battery and Common troubles.
Circuit Trouble
Normally when a circuit trouble occurs, the Trouble LED will be illuminated and the common trouble relay will
be active. Usually a relative event can be shown on the LCD event list view. Use these indications to correct the
fault, check for open wiring on that particular circuit loop.
In Addressable Loop Circuit
In Notification Appliance Circuit
In Auxiliary Power Circuit
Ground Fault
This panel has ground fault detection. To correct the fault, check for any external wiring touching the chassis or
other Earth Ground connection.
The maximum resistance for testing ground fault detection for extended wirings other than the network is 6.6
kohm.
The maximum resistance for testing ground fault detection for network wiring is 60 ohm.
Battery Trouble
Check for the presence of batteries and their conditions. Low voltage (below 20.4V) will cause a battery trouble.
If battery trouble condition persists, replace batteries as soon as possible.
Common Trouble
If only a common trouble is indicated on the main panel and none of those above confirming trouble indicators
are on, then check the following for possible fault
Any missing interconnection wiring
Improperly secured cabling
