5.5 FUNCTIONALITY DURING A SYSTEM FAULT
A system fault is indicated when a processor controlling a function in the panel has a watchdog time out or
processor failure. In the event of a system fault the particular board affected may not be functional. The
following indications may be observed.
Display Board
System Fault LED only continuous and continuous buzzer sound. Display board TPCA03 is halted and no other
indication or control is possible. Fault relay and fault output are activated. If a fire occurs alarm sounders and
outputs will still function.
Main Board or zone extender boards
System Fault LED continous and General Fault LED pulsing and continuous buzzer sound. Main board, or
extender card if fitted are halted. Fault relay is activated. Alarms may be activated on the unaffected board.
Repeater Comms Board
System Fault LED continuous and General Fault LED pulsing and Repeater Fault LED continuous. The Comms
Board TPCA05 is halted. Fault relay and output are active, and repeater panels will cease to function. Fire
alarms can still be detected and controlled by the panel.
System Fault recovery
System Fault LED pulsing and General Fault LED pulsing along with a pulsed buzzer (fault tone) a system fault
has occurred and the affected board has recovered. The indication will remain until the panel is reset.
5.6 USER INSTRUCTIONS
If an alarm condition is present YOU MUST FOLLOW YOUR NORMAL FIRE DRILL PROCEDURES.
A responsible person should then:-
1. Check the control panel to see which area or zone has caused the system to go into alarm. This will be
indicated by a pulsing red LED on the front of the control panel.
2. Go to the area which has caused the alarm to check if a fire exists.
3. Only when it is safe to do so should the alarms be silenced. Activate the controls by turning the key
switch or by entering the four digit code (see Activate Controls in the OPERATING section) and press
the (blue) SILENCE ALARMS button (fig 1). To sound the alarms again press the (red) RESOUND
button (fig 2).
4. In the event of a false alarm look for the device that has caused the alarm. A detector will have a red
LED lit, or check to see if a call point glass is broken (if so replace the glass or call an engineer).
5. When fully satisfied that there is no fire, return to the control panel and press the (green) RESET button,
(fig 3). The panel display should return to normal and only the green SUPPLY HEALTHY LED should be
lit on the control panel.
