3 Connecting the mains power

The fire alarm control panel must be connected to the 230 V AC mains via a double-pole circuit
breaker in the electrical distribution cabinet.
The cable must be at least 2 x 1.5 mm
panel wiring as much as possible. Strip the outer sheath of the cable as little as possible, so that
should one of the conductors become loose it cannot touch the control panel's 5 V or 24 V parts.
Fasten the cable in the place provided.
The installation may only be switched on during its commissioning.

4 Connecting the batteries

The batteries are sealed lead-acid batteries rated at 1.2, 3 or 7 Ah. Two 12 V batteries are
connected in series to provide 24 V.
The control panel has an integral automatic battery charger. The charging current is limited to
0.86 A and the charging voltage is regulated according to the temperature in order to maximise
battery life. The battery fuse is F2 on the main PCB: 3AT
The charging current is cut off in the event of an alarm, as allowed by EN54-4, which means that
there is more power available for the external devices.
The batteries are tested every 8 minutes. If a battery can no longer be charged or its connection
is loose, or if its internal resistance is very high, then a battery fault is indicated automatically.
Battery testing is also performed 30 seconds after every reset.
Sealed lead-acid batteries have an average service life of 5 years in this application, after which
their capacity falls drastically or they become faulty. It is therefore best to replace them within
this period. Write the date on a battery when it is installed as a replacement.
Batteries may only be connected during the commissioning of the installation.
If no batteries have been connected, the battery charger will switch on briefly at regular intervals.
If the batteries are nearly discharged and there is a high current demand, the charger will switch
to an on/off regime in order to limit internal heating.
