5.1 SOUNDER OUTPUT
The panel has two supervised sounder output rated 0.5А 24V DC. Overloading the output will cause a sounder output fault and fuse
activation. A 2x1.5 mm2 cable must be used as a sounder circuit. 10кΩ resistor, located on sounder output from factory default is
used as end-of-line element.
5.2 AUXILIARY POWER SUPPLY OUTPUT
The panel is equipped with an auxiliary 0.5А 24V DC power supply output. The output is used for energising external devices such
as telephone dialler or gas detector. Connecting an external device with improper voltage requirement or overloading the output
will cause device malfunction or output fault. The output provides continuous power supply. In case of mains power supply failure,
the batteries provide power supply to the output.
5.3 RELAY OUTPUTS
The panel has two relay outputs with volt free changeover contacts rated 1A 30V DC, NC and NO. If a relay output would be used
in an application requiring continuous high current - even below the rated values - an appropriate terminal should be used between
the device and the relay output.
6- CONTROLS
7- INDICATORS
Button Control key
To use the buttons, the Button Control key must be positioned to the Enable position. Enabling the buttons will cause the buzzer to
sound intermittently every 10sec.
Silence / Sound Alarm button
Pressing the button in normal condition will cause activation of the sounder output, the buzzer and the fire relay output as well as
illuminating of general FIRE LED.
Silence Buzzer button
Pressing the button will silence the buzzer.
Lamp Test button
Pressing the button will activate all LEDs and the buzzer thus testing their proper functioning.
Reset button
Pressing the button will reset fire and fault conditions as well as fire and fault relay outputs to return the panel to normal condition.
Processor Reset buton
Pressing the button will reset system.
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.

5.3.1 FIRE RELAY:
The fire relay activates on fire condition. The output is returned to its initial position by pressing Reset button provided no fire
condition is available. The fire relay is normally not energised.
5.3.2 FAULT RELAY:
The fault relay activates on fault condition. The output returns to its initial position automatically as soon as fault condition ends.
Fault relay is normally energised; this enables conveying a fault signal to a remote control unit when the panel goes out of power
supply.
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.
