The Status LEDs
The following section describes how the Control panel
LEDs operate, and the actions that can be taken during
the various phases signalled on the LEDs. During
standby status ONLY the GREEN Mains LED should
be On (glowing).
+
Some LEDs indicate more than one status, howe
-
ver, in most cases the LEDs signal as follows:
ON (glowing) indicates DISABLED status;
Fast blinking indicates a FAULT condition;
Slow blinking indicates an ALARM/FAULT event
in memory.

LED DESCRIPTION
Alarm Glowing indicates Alarm status. In the event of an Alarm, the Control panel will activate the unbypas
-
sed alarm outputs..
Pre-al. Glowing indicates Pre-alarm status.
Test Glowing indicates Test conditions on at least one zone.
Disab. Glowing indicates the Disabled status of the NAC,Telecom, Zone and Extinguishment outputs, or inhi
-
bition of Manual or Automatic Extinguishment
Telecom Glowing indicates that the Telephone device output is active (negative pull-down to 0 V on terminal
[DL]).
Green
Mains
OFF indicates Mains failure (230 V).
IMPORTANT: Power must be restored before the batteries empty.
Fault Glowing indicates one of the following Faults: Blocked Control panel; Shorted 24V or 24R output;
Empty Batteries; Disconnected Battery; Ground Fault; Mains Failure; Zone Trouble; Shorted or Open
NAC or DL output; Extinguishment Module Trouble; Peripheral Trouble.
Logic Unit Glowing indicates Blocked Control panel. IMPORTANT: Maintenance required.
NOTE – When the Control panel is switched on for the first time, this LED will flash until a Reset has
been performed.
24V/24R Fast blinking indicates Shorted 24V or 24R output.
Battery Fast blinking indicates Batteries empty, disconnected or faulty. If this condition persists, the batteries
will be unable to function as intended in the event of blackout, IMPORTANT: New batteries required
Ground Fast blinking indicates a Voltage leakage to Earth.
IMPORTANT: Check wiring insulation.
Periph. Fast blinking indicates communication trouble with peripherals.
Amber
Mains
Fast blinking indicates Mains failure (230 V) or Switching Power supply fault. During this condition,
the Control panel will be powered by the batteries. Mains failure is also signalled on the Green Mains
LED (OFF), however, this LED also signals Mains Failure in Memory (Slow blinking).
Silence Glowing indicates that Silenceable outputs (terminals [NAC1], [NAC2], [DL], [TROUBLE], [ALARM] (if
programmed) and [Rn] (if programmed) have been manually forced to standby by means of the re
-
spective key.
Ack./Evac. Glowing indicates that the programmed Investigation time is running.
Reset Glowing indicates that Reset operations cannot be carried out.
Night Mode Glowing indicates that the Control panel is operating in Night Mode.
Disab./Fault
NAC
Glowing indicates that the Supervised, Silenceable Fire Alarm outputs (terminals [NAC1] and
[NAC2]) have been disabòled by means of the respective key, therefore, in the event of alarm will not
be activated.
Fast blinking indicates that at least one of the Supervised, Silenceable Fire Alarm outputs (terminals
[NAC1] and [NAC2]) is shorted or open.
Disab./Fault
Telecom
Glowing indicates that the telephone device output (terminal [DL]) has been disabled by means of the
respective key, therefore, in the event of an alarm will not be activated.
Fast blinking indicates that the telephone device output (terminal [DL]) is shorted or open.
Disabled/
Fault/
Test
Glowing indicates that the respective zone has been disabled by means of the respective key, there
-
fore, will be unable trigger alarms. Fast blinking indicates that the respective zone is shorted or open,
therefore, unable to detect alarm conditions.
Zone Alarm Glowing indicates that the respective zone has detected alarm conditions.
