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

    •  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.
