We had a power outage last night. When the power came on, the battery backup was beeping and the “alarm silence” button was not doing anything. Does anyone know how to stop the beeping? Please don’t tell me the battery is dead. They replaced it last year and moved it last month.
Thanks in advance.
30 plus years as power lineman. If your power outage was from a storm trees down or a car through a pole slapping the wires together the voltage on the 120 volt circuit can surpass 200 volts. Your battery is supplying the beeping should be ok however the circuit board in the ont probably took a hit and is now a problem. Unplug it say for a hour and then try it might work? Any surge plug in bar (cheap) are useless after the first surge event. During lightening storms unplugging the electronics is the only way to save things. High end surge (whole House ones) work but they have to be tested and replaced after a period of time.
When the power company circuit breaker trips because of storm or accident the voltage always tends to spike and spikes are normally higher the closer you are to the fault. When they turn it back on it tends to drop lower than (sometimes) 100 volts because every ones load is coming on. Best give a 15 to 30 minute before turning on more stuff until the load on the wires settle down. It will save you added grief with your stuff. Weather conditions affect all of this..Polecat
