How to work with the D4112 Battery Discharge and Recharge voltage schedule.

David · ‎08-27-2018

The D4112 charging voltage is 13.5VDC at a maximum current of 700mA. Actual current may be lower due to auxiliary power draw.
After a loss of AC voltage, when the battery voltage drops below 11.3 VDC a Battery Trouble report is sent to the monitoring station.
During an extended AC Power loss, when the battery charge drops below 9.5 VDC, the bell output voltage is disabled to protect the battery from deep discharge.
When AC restores and the battery reaches a charge voltage of 12.5 VDC, a Battery Restoral Report is sent to the monitoring station.
The battery is fully charged when it reaches 13.5 VDC.
