Battery Backup
The 2-Door Controller cannot be started on battery power only. Battery backup time varies with each system.
Typical backup time is between 2 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.
12Vdc 7Ah rechargeable acid/lead or gel cell backup battery (UL/ULC: YUASA #NP7-12 recommended,
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), 320mA, 500mA, or 1A. Refer to the
ATRIUM user interface instruction manual for more information on how to modify the battery charging
current.
