6.0 Fault Indications
When the panel has detected a fault in any of the critical operating paths of the system it will display
this on the LCD. The internal buzzer will also pulse slowly.
The General Fault indicator will be illuminated and is always accompanied by other indicator(s)
detailing the exact fault.
In general, fault indicators flash until the fault is accepted (by touching the Accept button) the fault
indicator then illuminates steadily and the internal buzzer will be muted. Further faults activate the
buzzer again.
In the event of any fault the following action should be taken:-
• Investigate the fault, and then accept the fault by touching the Accept button.
• Note the fault down in the Logbook and take action to remedy the fault. In all cases expert
advice should be sought.
When the fault has been rectified the fault indicator will automatically extinguish.
Note: - Some faults latch and once rectified must be cleared by pressing Reset. Any faults that have not
been fixed will reappear.
The following sections give descriptions of each fault indication
6.1 System Fault
The panel performs regular self-tests to ensure the software is working correctly. If a fault is
detected in software operation a System Fault is declared. This is a latching fault and can only
be cleared by touching Clear System Fault. If the fault is still present it will then reappear.
6.2 Alarm Fault
A fault has been detected on one or more of the alarm devices connected to the loop or on
one of the sounder circuits. One or more alarm devices may no longer operate correctly.
6.3 Power Fault
A fault has been detected in the panel’s power supply. This may be because the local mains
supply has failed or because the internal stand-by batteries or circuitry are faulty.
6.4 Aux. Supply Fault
A fault has been detected with the Auxiliary 24V supply output of the panel. There may no
longer be an auxiliary supply to external devices or the auxiliary devices are drawing too
much current. The General Fault indicator will be illuminated accompanied by the ‘Aux Supply
Fault’ indicator.
