220 Series 7
Technical specifications
The power for the communicator is supplied by the panel to which it is connected (10.7 V to 27.6 V) or by an external power supply
which also recharges an optional backup battery, if necessary. The sole purpose of the battery is to supply power in case of failure
of the primary power source (8 hours stand-by).

When the communicator is powered by the battery, ONLY communicator events are transmitted.
The primary power and (optional) battery voltages are supervised.
The power supply for communicator models BGS-220 and B3G-220/EU must be SELV, with power limited to 1 A.
