safety.
Note: this conformity is also valid for the AF45342 activation point and the AF45339 electronic keys.
POWER SUPPLY UNIT
The power supply unit inside the control panel has two outputs:
• Output for the system power supply and the internal battery recharge, 13.8 Vdc (terminal 1).
• Output for recharging the self-powered siren battery 14.5 Vdc (terminal 12)
The power supply unit output is electronically protected against overloads; The total current at the two
outputs must not exceed the maximum value of 280mA. Three protection fuses are also provided for;
• Fuse Fu1 - 0.5A - to protect the siren circuit
• Fuse Fu2 - 0.5A - to protect the system (detectors and remote activation points)
• Fuse Fu3 - 1A - to protect against battery inversion
To make the total rating calculation easier, refer to the following table:
Note: To guarantee autonomy to the system, without mains power, for 24h, do not exceed
the maximum rating value of 50 mA.
