6.13 V3 BBU AND AP ALARM TROUBLESHOOTING
This section provides a guide to troubleshoot each type of individual system alarm for a BBU or Annunciator
Panel. See below for a description of the cause of each alarm and the remedy to troubleshoot/fix the alarm.
Loss Of Normal AC Power
Cause
No AC Power detected, or the AC switches are OFF.
Remedy
Check AC power source. Check AC switches in the BDA and BBU
Battery Low Alarm
Cause
AC Power was lost for an extended period. The Battery capacity is lower than the threshold
(normally 30%). Incorrect wiring between BDA/MU/RU and BBU.
Remedy
1)Login to the WEB GUI to check the specific alarms that caused Battery Low Dry Contact
Alarms.
2)Check that AC Power is normal. Fix if necessary.
3)Check Battery Low threshold and current battery capacity, in Overview – <Internal Charger>
Tab. Adjust threshold if necessary. Default is 30% per most code requirements.
4)Check “RUN on Battery” time and “SOC (State of Charge)”, in Overview – <Internal Charger>
Tab. If the device is running on the Battery, this indicates a Loss of AC Power or a potential
charger failure. Check AC Power source and power-cycle devices.
If the problem persists, call Technical Support.
