12.5 Battery Restart after Deep Discharge (S3)
The Battery Restart switch (S3) is to be pressed only in case you
need to commission the panel by means of the batteries (if the
mains power is not available). A complete hardware reset will take
place.
The switch turns on the relay in the battery circuit.
If the system is run from battery and the battery is replaced, the
switch must be operated to restart the system
EN54 part 4 states that if the battery voltage drops below a limit
specified by the manufacturer (17V) the battery shall be
disconnected to prevent deep discharge. The battery is
disconnected using a relay.
