7.1 Front case indicators
Power On
Continuous illumination indicates that the panel is energised. Flashing indicates fault in mains or battery power supply.
General Fault
Illumination indicates any fault condition. This would typically be:
- Mains power supply or battery voltage is low,
- Leak from ‘+’ or ‘-‘ wire to earth,
- Open or short circuit on the sounder circuit,
- Open or short circuit on the zone circuits,
- Overloading of the auxiliary power supply output.
Power Fault
Illumination indicates power supply fault condition.
Earth Fault
Illumination indicates current leakage from ‘+’ or ‘-‘ contacts to earth.
Alarm / Buzzer Silenced
Flashing indicates that sounder output or both sounder output and buzzer are silenced. Continuous illumination indicates that only
the buzzer is silenced.
9- PANEL CONDITIONS
Page 6/16 KK-642.042 Rev.No:0 01.11.12 ML-221XX User Manual
Disable
Flashing indicates any disablement condition.
Sounder Fault
Illumination indicates open or short circuit on the sounder output.
Zonal faults
Illumination indicates;
Short circuit on the zone cabling,
Open circuit,
Connection problems between detector and base,
End of line resistor wiring problems
8- FUSES
SOUNDER OUTPUT FUSE (F2,F3)
The self-resetting fuse activates on 0.5А current overload on the sounder circuit. The overloading would typically be caused by
connection of too many devices to the output.
BATTERY FUSE (F4)
The self-resetting fuse activates on 0.5А overload or a short circuit on battery inputs.
AUXILIARY POWER SUPPLY OUTPUT FUSE (F1)
The self-resetting fuse activates on 0.5А overload on the auxiliary power supply output. The fuse activation causes illumination of
the General Fault LED and buzzer sounding.
MAINS FUSE
The glass type fuse activates on 5А current overload, a short circuit or exceeding 230V AC on mains supply input. On activation of
the mains fuse the batteries energise the panel.
9.1 NORMAL
In normal condition, only the Power On LED should illuminate.
9.2 FIRE
Upon receiving of a fire signal from detector or manual call point, respective zonal FIRE LED(s) illuminate(s) with the main FIRE
LED. The sounder output, the buzzer and the fire relay output activate. In this condition, first of all, position the Button Control key
to Enable and press the Silence / Sound Alarm button. The sounder output will silence. The zone, from which the fire alarm signal
has been received, should be checked immediately. On fire signal confirmation, press the Silence / Sound Alarm button to reactivate
the sounder output. If there is no fire, eliminate the cause of the false alarm and press the Reset button to return the system to
normal condition.
9.3 FAULT
Upon receiving any fault signal, General Fault LED illuminates, the buzzer sounds and the fault relay activates. Respective zonal
Fault LED illuminates if the signal is received from specific zone. The system returns to normal condition automatically as soon as
fault condition ends.
