AbsoluteInspector Posted January 8, 2014 Report Share Posted January 8, 2014 I did a home inspection yesterday and when I tripped one of the GFCI outlets in the bathroom all the smoke detectors went off. (It did this once and I could not get it to happen again on purpose). The smoke detectors are wired into the electrical system and I was wondering if this is a common false positive or signs of a greater problem??

Charlie R Posted January 10, 2014 Report Share Posted January 10, 2014 You sure someone else wasn't testing a smoke detector while you were busy tripping the GFCI? Quote Link to comment Share on other sites More sharing options...
John Kogel Posted January 10, 2014 Report Share Posted January 10, 2014 The electrician ran a feeder from a bathroom plug up to a smoke alarm in the hall. The alarms are daisy-chained together. I don't know why they would not ring again but maybe you pushed a standy by button. Or the GFCI wasn't reset or tripped again. AFAIK, the bathroom receptacles are not normally shared with any other outlets. That's what I'd report. It is easy enough for an electrician to find a new power source for the alarm.

Why would cutting power to the smoke alarms cause them to sound? My house loses power at least once each winter and our smoke alarms don't holler.

There is at least one type that beeps when power is cut. Maybe the alarms that are tied to home alarm systems will do that. There might be another situation, the alarm will beep when AC is cut because the backup battery is low, in which case it will beep again and keep beeping at 1 minute intervals, but if you restore AC power it shuts up.
