Discharge Cycle AC Off AC Fail Report when AC fails, if the control panel is programmed to report AC failure at occurrence. 13.9 VDC Charging float level. 13.8 VDC Charging status LED on. 12.0 VDC Low Battery and AC Fail Reports if programmed. Low battery LED on. 10.0 VDC Battery load shed (processing functions continue if AC is present). Recharge Cycle AC On Load shed relay reset; battery charging begins; Battery Trouble and AC Restoral Reports are sent. 13.7 VDC Battery Restoral Reports are sent. Low battery LED off. 13.9 VDC Changing status LED off; battery float charged.                                                        Charging Status and Low Battery LEDs Type LED Action Color State Charging Status LED Yellow   Shows the charging status of the battery.   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. Indicates the combined current draw from all outputs exceeds 1.4 A. This is normal under alarm conditions for non-fire systems with sirens or bells drawing more than 1.4 A. If the LED lights regularly for extended periods or does not go out, check the current draw for devices connected to the power outputs.   Yellow Flash once per minute System is checking the battery. Low Battery LED Red   Shows the condition of the battery.   Red Off Battery is fully charged.   Red On Battery voltage dropped to between 12.0 VDC and 11.8 VDC.  LED turns off when voltage reaches 13.7 VDC.   Red Flash Battery is missing or shorted.   ...

 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.   ...

 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. ...
