My husband bought a new smoke alarm about a year or two ago. I can't find the instructions that came with it.
I have 4 electronic smoke detectors with battery backup on the same line. One detector beeps every 50 seconds non stop.
I have a smoke detector problem. It keeps beeping off and on. I changed the batteries and it still will beep off and on.
My smoke alarm is connected to electric supply and has started going off for no reason at all the last few days.
