4.
With all Backup Alarm connections disconnected from the Interface Board and the buzzer sounding
continuously, disconnect the ribbon cable between the Interface Board and the Main Control
Processor Board. Ignore any faults indicated.
If the buzzer continues to sound after pressing Accept replace the Main Control Processor
Board.
If the buzzer is silenced after pressing Accept replace the Interface Board.
5.
Reconnect the Backup Alarm connection, this shall cause the buzzer to sound continuously.
6.
Isolate all detectors on the associated engine and disconnect all detectors.
If the buzzer stops after pressing Accept the fault is associated with a detector, go to 9.
If the buzzer continues to sound go to 7
In the Junction Box disconnect the Backup Alarm connection to the Control Panel, TB9.
If the buzzer continues to sound after pressing Accept replace the cable between the Control Panel and
the Junction Box.
7.
Reconnect the Backup Alarm connection, this shall cause the buzzer to sound continuously.
8.
In the Junction Box disconnect the Backup Alarm connection, grey wire, from each detector cable.
If the buzzer stops sounding replace the associated detector cable.
If the buzzer continues to sound after disconnecting all of the detector backup alarm
connections replace the Junction Box PCB.
9.
Reconnect each detector one at a time.
If the buzzer sounds continuously replace the associated detector.
With the fault cleared and the buzzer silenced ensure all wiring connections are made, detectors are de-
isolated.
Perform a Backup Alarm test, see 3.5.5.
5.2.11
Control Panel Reset
The Control Panel continually checks both internal power supply and the operation of the software to
ensure that it has not been corrupted or locked up. If the internal power supply is not within specification
or an error in the software operation occurs an automatic reset will be performed to restart the Control
Panel operation.
If the Control Panel restart has been successful restarted the system will continue as normal with no
loss in performance.
If the fault persists the Control Panel will continue to reset every 1 2 seconds.
1.
Using a multi-meter measure the voltage across diode D13 on the Interface Board.
2.
The measured voltage should be between 4.5v and 5.5v.
If the voltage is outside the limits go to 3.
If the voltage is within the limits go to 7.
3.
Remove the power from the system
4.
Disconnect the power and ribbon cables between the Interface board and Main Control Processor
Board.
5.
Switch on the system, ignoring any faults indicated.
6.
Using a multi-meter, measure the voltage across diode D13 on the Interface Board.
If the voltage is outside the limits replace the Interface Board.
7.
Using a multi-meter, measure the voltage across diode D4 on the Main Control Processor Board.
8.
The measured voltage should be between 4.5v and 5.5v.
If the voltage is outside the limits go to 9.
