The battery charger section works as follows:

In case of power supply missing, the control panel is fed by the backup batteries. The
green LED turns off.

If the battery voltage drops below the low-battery threshold, an acoustic (buzzer) and
visual (on-screen message) signal are activated

In this situation, to restart the control panel, restore the network power supply.

If no battery is installed, at the first battery control carried out periodically by the
control panel, an acoustic (buzzer) and visual (on-screen message) signal are
activated to signal that the batteries in the control panel are missing.

If the battery's internal resistance (including the resistance due to contacts and cables)
is higher than 8
00 mΩ, the control panel will emit an acoustic (buzzer) and optical (on-
screen message) alarm.
The value of internal resistance is refered to 7,2Ah batteries.
As far as the ope24 V power supply section for external loads is concerned:

The voltage output is protected against short circuits.

In case of a short circuit an acoustic (buzzer) and visual (on-screen message) signal is
activated.
7.9 Panel internal cabling
The panel internal cabling has to be done in such way to be easily accessible in case of
future maintenance.
The cables can enter into panel unit through the holes provided on the upper part of the box
and on the back.
Cable outlet for 22 mm diameter must be use.
It is important to connect the cable shields to an earth terminal in the panel mechanics.
For closed loops, connect only one side of the shield, leaving the other side disconnected.
