Battery lead supervision
The battery charging float level occurs at 13.65 VDC. If the battery voltage drops below 12.1
VDC, the B465 sends a LOW BATTERY report, and indicate a Low Battery on the LED if
programmed to do so. The B465 (if programmed for battery supervision) sends a Battery Low
report. It sends a Low System Battery (302) report in the Contact ID format. It also lights the
LOW BATTERY LED.
If programmed for battery supervision, the B465 adds a missing battery event to the event log.
If programmed for battery fault reports, the control panel sends a BATTERY MISSING report,
or Control Panel Battery Missing (311) report in the Contact ID format.
When battery voltage returns to 13.4 V or higher, the B465 turns the LOW BATTERY LED off. If
the B465 is programmed for battery supervision, it sends a BATTERY RESTORAL report, or a
Control Panel Battery Restored to Normal (302) report in the Contact ID format.
Investigate LOW BATTERY events immediately. If primary (AC or DC) power is off and the
discharge continues, the B465 becomes inoperative when the battery voltage drops below
10.2 VDC, and the battery cutoff relay deactivated.
