5.2.3 Replacing the Battery
Replace batteries every 3 to 5 years under normal use.
Record the date of installation directly on the battery.
Caution: Exceeding the maximum output
ratings or installing the transformer in an
outlet that is routinely switched off causes
heavy discharges. Routine heavy discharges
can lead to premature battery failure.
D8132 Boost Battery Backup: Adding a D8132
Battery Charger Module supports additional batteries
of up to 27 Ah capacity, if required. The D8132 Battery
Charger Module can be used to connect two additional
batteries for a total of four.
The control panel plus any connected D8132 Modules
and auxiliary power supplies must be on the same AC
circuit to discharge evenly if AC power fails. The
number of D8132 Modules is determined by the
number of available outlets on the same circuit. Refer
to the Standby Battery and Current Rating Chart in the
D9412GV2/D7412GV2 Approved Applications Compliance
Guide (P/N: F01U003639) for battery standby time
calculations.
In applications where the supervision of two
batteries is required by the AHJ, use a D113
Battery Supervision Module.
