4.3 Fault Condition
When the system registers a fault condition:
 Common FAULT LED will be illuminated
 Corresponding front panel fault LED will illuminate
 Assigned zone fault LED will flash
 Panel buzzer will sound intermittently
 Fault condition to be reported to the LCD.
 The fault event will be logged and printed, where a printer is fitted.
 The panel fault output will activate
 All outputs configured to operate under a fault condition will operate
The fault condition will be displayed on the LCD in the following format:
Zzzz FAULT
<zone descriptor>
<date> <time> CONTROL*
FAULT XXX OFXXX DEVICE►
Only zoned input types shall be displayed collectively as a zone.
<point location> FAULT
<point descriptor> <type>
<date> <time> CONTROL*
FAULT XXX OF XXX ◄DEVICE
Faults originating from sounders, outputs and un-zoned modules on loops, add-ons or the panel
main termination board shall be displayed individually as shown here.
Pressing the “DEVICE►” forward button will allow the panel to display all the individual inputs,
outputs and modules in fault.
Selecting “CONTROL*” will allow direct entry into the control menu for the current point or zone
being displayed (This operation is only available at access level 2).
4.3.1 System Fault Condition
(EN54.2:1997: 8.5, 13.4, 13.6, 13.7a)
The System Fault condition is activated if the FACP fails to provide mandatory functions. When a
system fault condition occurs, the panel buzzer, System Fault and General Fault indicators shall be
activated.
Mandatory functions failures include:
 Critical hardware failure on Main Termination Board (MTB) – The system fault condition is
driven by hardware for this failure and can be cleared by hardware reset or power cycle of
the MTB if the hardware is not damaged.
 Reset of the CPU on the MTB while the MTB maintains power – The panel shall re-initialise
if possible and the system fault condition shall be driven by software. In this case the fault
buzzer is silence-able at access level 1 or higher by using the SILENCE BUZZER control
and the system fault can be cleared by activating the RESET control at access level 2 or
higher. If the RESET control is activated at access level 1, the user shall be prompted to
enter a password; successful entry of an access level 2 or 3 password shall complete the
action.
 Loss of communications with the Front Panel (FP) – The system fault condition shall be
hardware driven on the FP via the software in MTB and can be cleared by hardware reset or
power cycle of the FP if it is not damaged. The system fault condition is not resettable or
silence-able whilst the condition is driven by hardware. Upon successful reset of the FP, the
system fault condition shall remain latched and shall be driven by software. In this case the
condition is silence-able at Access level 1 by using the SILENCE BUZZER control and reset-
able at access level 2 or higher by using the RESET control.
 Memory corruption (checked hourly) – The system fault condition shall be driven by
software. The panel shall be forced to diagnostics mode and all outputs shall be switched
off. The system fault buzzer may be silenced in this instance by using the SILENCE
BUZZER control access level 1 or higher and cleared by activating the RESET control at
access level 2 or higher.
