LED Indication
The operation of the LED indication on the front of the control panel is described below.
Description
Colo
ur
State Reason
1. ‘FIRE’ LEDs Red Continuous The control panel is in the fire state. Other indicators
will show the origin
2. ‘DETECTOR ALARM’ LED(s)
Red Flashing A smoke or heat detector is in the alarm state and
sending an alarm signal to the panel. The Multipoint
LED will be on continuously.
3. ‘CALL POINT ALARM’ LED(s)
Red Continuous A manual call point is in the alarm state and sending
an alarm signal to the panel. The manual call point
LED will be flashing.
4. ‘FAULT’ LED
Amber Continuous This indicates the status of the multifunction
FAULT/DISABLE/TEST LED.
5. ‘DISABLE’ LED
Amber Continuous This indicates the status of the multifunction
FAULT/DISABLE/TEST LED.
6. ‘TEST’ LED
Amber Continuous This indicates the status of the multifunction
FAULT/DISABLE/TEST LED.
7. ‘FAULT/DISABLE/TEST’ LED
with ‘FAULT’ LED continuous
Amber Flashing at
same time as
buzzer.
Flashing twice
in between
buzzer pulses.
No ‘End of Line’ signal is being received, eg:
EOL not switched on
An open or short circuit exists on the wiring.
A device is signalling a fault condition, or more than
one device is set to ‘End of Line’, eg:
Optical Chamber removed.
Optical Chamber contaminated or dusty.
Output Module fault loop open circuit.
Output Module has no 24V DC supply.
8. ‘FAULT/DISABLE/TEST’ LED
with ‘DISABLE’ LED
continuous
Amber Continuous The zone has been disabled at Access Level 2
(User).
9. ‘FAULT/DISABLE/TEST’ LED
with ‘TEST’ LED continuous
Amber Continuous The zone is in test mode.
10. REMOTE FIRE OUTPUT ‘ON’
or ‘ACTIVE’ LED
Red Continuous The Remote Fire Output (monitored relay circuit) has
been activated by the control panel.
11. REMOTE FIRE OUTPUT
‘FAULT/DISABLE’ LED
with ‘FAULT’ LED continuous
Amber Flashing The Remote Fire Output (monitored relay circuit) has
detected a fault condition, eg:
An open or short circuit exists on the wiring.
The 4K7 EOL resistor is not fitted.
A device fitted is not dioded for polarisation and
suppression
12. REMOTE FIRE OUTPUT
‘FAULT/DISABLE’ LED with
‘DISABLE’ LED continuous
Amber Continuous The Remote Fire Output (monitored relay circuit) is
disabled.
13. ‘REMOTE FIRE INPUT’ LED
Red Continuous The Remote Fire Input is in the fire state.
14. ‘SOUNDER FAULT’ LED Amber Continuous The Remote Fire Output (monitored relay circuit) has
detected a fault condition, eg:
An open or short circuit exists on the wiring.
The 4K7 EOL resistor is not fitted.
A device fitted is not dioded for polarisation and
suppression
This only relates to the conventional sounder circuit,
not the 2-wire zones.
