7.0 System Fault Indications
When the 3100 has detected a fault in the critical operating path of the system it will display
this on the front panel display. The internal buzzer will also sound intermittently (slowly).
The ‘General Fault’ indicator will be illuminated and is always accompanied by other
indicator(s) detailing the fault.
In general, fault indicators flash until the fault is accepted (by pressing the ‘Mute Buzzer’
button) the fault indicator then lights steady 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:
• Mute the fault by pressing the ‘Mute Buzzer’ button on the panel.
• Note the fault down in the Log Book 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.
The following sections give descriptions of each possible fault.
7.1 Zone Faults
The 3100 shows any faults on the detection zones on row 2 of the front panel display. The
‘General Fault’ indicator will be illuminated accompanied by the relevant zone indicator.
Pressing ‘Mute Buzzer’ will mute the buzzer but WILL NOT make the zone indicator go
steady.
7.2 System Faults
The 3100 performs many self tests to ensure the software is working correctly.
The fault should be cleared by pressing ‘Silence Alarms’ then ‘Reset Panel’ whilst in access
level 2.
If the fault re-occurs with 3 minutes the 3100 has a microprocessor fault, and the
maintenance manager must be alerted.
7.3 Alarm Faults
A fault has been detected on one or more of the four sounder outputs. One or more of the
sounder circuits may no longer operate correctly.
7.4 Power Supply Faults
A fault has been detected in the power supply module of the 3100. This may be because the
local mains supply has failed or because the internal stand-by batteries or charger are faulty.
7.5 Fire Link Fault
A fault has been detected on the monitored fire link path. This may be a wiring fault of the fire
link interface fault. The connection to the fire station link is no longer reliable. Expert advice
should be obtained immediately.
7.6 Aux 24V Fault
A fault has been detected with the Auxiliary 24V supply output of the panel.
7.7 Repeat Panel Fault
A fault has been detected on a 3100 repeat panel connected to the 3100 main panel, or the
wiring to the repeat panel is faulty.
