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.
Replace batteries every 3 to 5 years under normal

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 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 D9412GV3/D7412GV3 Approved Applications
Compliance Guide (P/N: F01U143069) for battery
standby time calculations.

5.2.4 Battery
Supervision
When battery voltage drops to 13.8 VDC, the yellow
Charging Status LED illuminates. When the battery
voltage drops to 12.0 VDC to 11.8 VDC, the red Low
Battery LED lights, and the keypad or keypads display
SERVC LOW BATT. The control panel (if
programmed for power supervision) sends a
BATTERY LOW report in the Modem IIIa
Charging Status LED illuminates. When the battery
voltage drops to 12.0 VDC to 11.8 VDC, the red Low
Battery LED lights, and the keypad or keypads display
SERVC LOW BATT. The control panel (if
programmed for power supervision) sends a
BATTERY LOW report in the Modem IIIa
2
communication format. It sends a Low System
Battery (302) report in the Contact ID format.
If the battery is missing or shorted, the red Low
Battery LED flashes at the same rate as the green
Operation Monitor LED. If the control panel is
programmed for power supervision, it sends a
BATTERY MISSING report in the Modem IIIa
Battery (302) report in the Contact ID format.
If the battery is missing or shorted, the red Low
Battery LED flashes at the same rate as the green
Operation Monitor LED. If the control panel is
programmed for power supervision, it sends a
BATTERY MISSING report in the Modem IIIa
2
communication format, or Control Panel Battery
Missing (311) report in the Contact ID format.
When battery voltage returns to 13.7 VDC, the Low
Battery LED turns off and the keypad or keypads
clear the SERVC LOW BATT message. If the control
panel is programmed for power supervision, it sends
a BATTERY RESTORAL report in the Modem IIIa
Missing (311) report in the Contact ID format.
When battery voltage returns to 13.7 VDC, the Low
Battery LED turns off and the keypad or keypads
clear the SERVC LOW BATT message. If the control
panel is programmed for power supervision, it sends
a BATTERY RESTORAL report in the Modem IIIa
2
communication format or a Control Panel Battery
Restored to Normal (302) report in the Contact ID
format. At 13.9 VDC, the yellow Charging Status LED
stops lighting.

Investigate Low Battery reports immediately: If
primary (AC) power is off and the discharge
continues, the control panel becomes inoperative
when the battery voltage drops below 10.2 VDC.
5.2.5 Battery Charging Circuit
Float Charge
The float voltage for the battery charging circuit is
13.9 VDC at a maximum current of 1.4 A, less any
devices connected to the control panel. If the float
voltage drops below 13.8 VDC due to overload or
battery discharge, the yellow Charging Status LED
lights.
Loss of AC Load Shed Relay protects battery:
During an AC power loss, the battery supplies all
power to the security system. If the battery voltage
falls below 10.0 V during an AC power loss, a load
shed relay isolates the battery from the control panel
and disables the control panel. Load shed protects
the battery from being damaged by deep discharge.
When AC power restores, the load shed relay
reconnects the charging circuit on the control panel to
the battery and the battery begins to recharge.
Overcharge Load Shed With AC Present: If more
than 1.4 A of auxiliary current draw from the control
panel occurs, the battery supplies the current and
begins to discharge. If this situation is not corrected,
the battery continues to discharge and at 11.8 VDC to
12.0 VDC, the keypads display Serv Low Batt.
When the battery voltage drops below 10.0 VDC, the
control panel shuts down. Remove all loads to the
control panel and disconnect AC power. Fix the
condition creating the over current. Add a new battery
and reconnect AC power.
A shorted battery condition is created either by a
shorted cell inside the battery or by a short on
Terminals 4 and 5. A shorted battery might cause the
control panel to operate in an unsafe way. This
condition generates WATCHDOG RESET reports.
