The battery backup is designed to step in if the power goes out and charged by the power adapter until fully charged.
In certain circumstances, there is an issue wherein once fully charged, the charging stops and the charging of batteries does not re-start unless the power to unit is turned off and on. Once charged the Batteries will hold power for 4 months and then will no longer work as expected.
There is a potential fire emergency hazard where the Flash Receiver is connected to the Visit Alerting System smoke alarm and a fire occurs at the same time as a power cut or outage; as in this situation the back-up batteries may be empty and not able to alert the user of a possible fire.
What to do...
Disconnect and reconnect the receiver. This will recharge the receiver and provide another approximately four months back-up functionality. Repeat every 3-4 months until the repair is available.
