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.

B520 Auxiliary Power Supply Module: The
addition of a B520 used to power any devices
that the control panel is unable to support will
increase the battery level back up to 36 Ah.
Use of a D8132 increases the battery level back
up by up to 27 Ah, and requires that the D8132
and control panel be connected to the same AC
branch circuit to allow for an even discharge.
Refer to the Standby Battery and Current Rating
Chart in the 17.0 Approved Applications of this
