4.2.6 Battery Discharge/Recharge Schedule
Discharge Cycle
AC OFF AC fail report when AC fails if panel is
programmed to report AC failure at
occurrence.
13.9 VDC Charging float level
13.8 VDC Charging Status LED on
12.1 VDC Low Battery & AC fail reports if
programmed; Low Battery LED on
10.2 VDC Battery load shed (processing
functions continue if AC is
present)
Recharge Cycle
AC ON Load shed relay resets, battery
charging begins, battery trouble
and AC restoral reports sent.
13.7 VDC Battery restoral reports sent, Low
Battery LED off
13.9 VDC Charging Status LED off, battery
float charged

Yellow Shows the charging status of the battery. Figure 6 shows its location.
Yellow Off Battery is fully charged.
If the battery is missing, shorted, or reversed: The Charging Status
LED is off, but the red Low Battery LED is flashing.
Yellow On
Battery float charge is below 13.8 VDC. If AC is present the battery is
charging.
When the combined current draw from all outputs exceeds 1.4 amps.
This is normal under alarm conditions for non-fire systems with sirens or
bells draw more than 1.4 amps. If the LED comes on regularly for
extended periods or doesn’t go out, check the current draw for devices
connected to the power outputs. See section 5.0
Power Outputs for
