4- INPUTS
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.

The chosen site for the mounting of the panel must be clean, dry and not subject to shock or vibration. The panel must not be
mounted near to sources of excessive heat or cold (see the specifications). Mark the position of the fixing holes according to the
respective Annex, ensuring that the wall is flat at the chosen location. Screws or bolts of a minimum of 4mm diameter must be used
to mount the cabinet in all mounting positions. Panel cable entries from back and top of the panel are available for easy mounting.
Drill and plug the wall then fix the cabinet using all fixing points. Open the panel front cover using the key provided.
4.1 MAINS POWER SUPPLY
The system is designed to operate with 220V AC 50Hz. Earth connections must be made to earth terminal and earth resistor must
be less than 10Ω. The mains supply of the panel must be via an independent self-resetting fuse rated 6A 220V AC. This fuse must
be separate from the other fuses and a caution note should be written such as “ATTENTION! FIRE ALARM CONTROL PANEL’S FUSE.
DO NOT REMOVE” to ensure safe operation of the panel. Recommended cable types for mains power supply are 3x2.5 NYM or 3x2.5
NYA. Do not connect or disconnect detection circuits, mains supply input and PCB connections while the panel is energised to avoid
an electric shock.
4.2 BATTERIES
Batteries provide continuity of operation during a failure of the mains power supply. The power supply has an automatic battery
charger circuit, so there is no need for an external charging unit. The panel uses two units of 12V DC 7Ah dry type batteries.
4.3 ZONES
Zone circuits provide supply to detectors and manual call points, and conduct fire, short circuit and open circuit signals. Please refer
to the respective Annex for connection scheme. Each zone is capable of hosting up to 20 fire detectors and infinite number of
manual call points. The characteristics of the cable is dependant on the length of the circuit: for a circuit of 0-500 meter long, use
1x2x0.8+0.8J-Y(st)Y cable, for a circuit of 500-1500 meter long - 1x2x1.5+1.5J-Y(st)Y. A 6.8kΩ resistor must be connected to
unused circuits and after the last device on the circuit as an end-of-line element.
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.
