Power Over Ethernet
12Vdc 7Ah rechargeable acid/lead or gel cell backup battery.
Europe: CDVI B7AH recommended). Ensure proper polarity. Various (means any type, from any
manufacturer that complies with the “Technical Data and securement means” and meets the “Mark of
conformity” can be used).
The battery charge current can be set to either 250mA (default), 500mA, or 1A. Refer to the ATRIUM
software to modify the battery charging current.

BATTERY BACKUP
The A22K cannot be started on battery power only. Battery
backup time varies with each system. Typical backup time is
between 4 and 20 hours using standard equipment and settings.
Wire a 12Vdc (either 4.5Ah or 7Ah) gel type battery and then
connect it to the BATT “+” and “-” terminals with the battery
leads supplied.
The pre-assembled PoE+ Splitter seperate data
and power coming from PoE+ source, example:
PoE+ switch or injector
