Symptoms Possible Cause
Circuit
Trouble
When a circuit trouble occurs, its designated trouble indicator will be illuminated, as well
as the Common Trouble LED and trouble buzzer. To correct the fault, check for open
wiring on that circuit, and check that the circuit is not disconnected or bypassed. For
information about bypassing and disconnecting, see sections , , and .
Note: Disconnecting a circuit will cause a system trouble (off-normal position).
Remote Fail
Remote Fail is indicated on the main panel display for any failure reported by, or failure
to communicate with a remote annunciator or other remote device.
Ground Fault
The panel has a common ground fault detector. To correct the fault, check for any
external wiring touching the chassis or other earth ground connection.
Battery
Trouble
Check for the presence of batteries and their conditions. Low voltage (below 20.4 V) will
cause a battery trouble. If the battery trouble condition persists, replace the batteries as
soon as possible.
Walk Test
Mode
If the LCD display indicates a walk test, the system is in walk test mode. See .
Common
Trouble
If only the Common Trouble LED is illuminated on the main panel and none of the
above trouble indicators are on, check the following for possible fault:
• Any missing interconnection wiring.
• Any missing module that was part of the configuration.
• Improperly secured cabling.
