How to work with the D6112 Battery Discharge and Recharge voltage schedule.


  •  The D6112 charging voltage is 13.6 VDC 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 12 VDC a Battery Trouble report is sent to the monitoring station.

  • During an extended AC Power loss, when the battery charge drops below 10.5 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 13.1 VDC, a Battery Restoral Report is sent to the monitoring station.

  • The battery is fully charged when it reaches 13.6 VDC. https://community.boschsecurity.com/t5/image/serverpage/image-id/1027i429E9A6E655C390F/image-size/large?v=v2&px=999
