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 options.
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
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, therefore, replacement is required.
Ground
Fast blinking
indicates a Voltage leakage to Earth.
IMPORTANT:
Check wiring insulation.
Periph.
Fast blinking
indicates communication trouble with peripherals.
Red 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
duly programmed) and [Rn] (if duly programmed) have been manually forced to standby by means of
the respective 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 (termi-
nals [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, therefo-
re, 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.
