1.1.3 Electrical specifications
• Earthing
Earthing must be carried out in compliance with electrical safety regulations; the total resistance of the circuit must be lower
than 10Ω.
The earth wire must be connected to the “earth” input of the fire panel terminal.
• Main power supply
In normal conditions, the fire panel is powered by the mains electricity supply. If the mains power is cut off, the power supply
is guaranteed by means of a rechargeable backup battery. The electrical specifications of the main power supply are provided
below:
◊ Main power supply - 110-230 VAC
◊ Frequency - 50/60 Hz
◊ Backup power supply - for 4 Loops 1 x 12 V / 18 Ah SLA (Sealed lead-acid)battery; 2 batteries for 8 Loops
◊ Internal battery resistance - <0.3 Ohm
◊ Max. continuous output current Imax.a - 2.7A
◊ Max. output current (batteries not charged) Imax.b - 5.0A
◊ Min. output current lmin. - 0.2A
◊ Output voltage (U) - from 10.2 V to 14.3 V (13.65 V @ 20°C)
◊ Electrical output - 4 loops 14.8A / 8 loops 29.6A
◊ Operating temperature - from -5°C to +40°C
◊ Protection rating - IP 30
• Consumption
From the electricity mains in standby mode:
◊ Configuration with 1 loop: 65 mA AC
◊ Configuration with 2 loops: 75 mA AC
◊ Configuration with 3 loops: 85 mA AC
◊ Configuration with 4 loops: 95 mA AC
Only with backup power in “Fault” condition, generating the message “AC loss”:
◊ Configuration with 1 loop: 285 mA DC
◊ Configuration with 2 loops: 360 mA DC
◊ Configuration with 3 loops: 435 mA DC
◊ Configuration with 4 loops: 510 mA DC
• Power supply and battery
◊ Output voltage (U): 13.8 V
◊ Output current: 20A
◊ Internal rechargeable battery resistance Ri: <0.3 Ohm
◊ Battery: 1 x 12 V/18 Ah, SLA (Sealed lead-acid) type
◊ Battery dimensions: 167х181х76 mm
◊ Battery connection type: with ring terminal Ø5 mm (M5)
• List of fuses
◊ Main power supply: 4А, Type Т
◊ Outputs: 0.1А, Type PTC (3); 0.3A Type PTC (1); 1A, Type PTC (1)
◊ Battery: 15А, Type PТC
CAUTION: the fire alarm panel should not be installed near sources of strong electromagnetic fields (radio
transmitters, electric motors, etc.)!
CAUTION: the panel should only be installed by qualified personnel.
The electronic components in the panel are vulnerable to electrostatic discharge.
NEVER make hardware changes when configuring the panel while the main or backup power supply is
enabled!
