Battery Discharging
Indicates battery is beginning to discharge and DC output voltage is below factory alarm setpoint
(see Table 13) or the configured level if setpoint is adjusted using keypad or SENS Setup Utility.
The BATTERY DISCHARGING alarm is the first to trigger of three low output voltage alarms and is
followed by LOW DC and then END OF DISCHARGE. Alarm setpoint must be set higher than LOW
DC and END OF DISCHARGE alarms. Activates solid yellow DC LED. Alarm/communications circuit
board BATTERY DISCHARGING relay contacts change to Fail state after delay when alarm is
assigned to relay contacts.

Low DC Voltage
Indicates battery has discharged and DC output voltage is below factory alarm setpoint (see Table
14) or the configured level if setpoint is adjusted using keypad or SENS Setup Utility. Alarm
setpoint must be set lower than BATTERY DISCHARGING and higher than END OF DISCHARGE
alarms. Activates solid yellow DC LED. Alarm/communications circuit board LOW DC relay
contacts change to Fail state after delay when alarm is assigned to relay contacts.
