Why are my smoke detectors making so much noise?

Question

I was at home, and all of a sudden all the smoke detectors started beeping at the same time, and when they stopped, they all stopped at the same time.

Answer 1

Are they going off, or are they "chirping"?  If they're chirping it means their battery is low and are asking to be replaced.

I'm guessing here, but did they go off during a thunder storm? I once had lightning strike very close to my house, the explosive boom set off my smoke detectors and security system all at once.

Answer 2

Live in California Do You?

Thick with smoke lately!

Answer 3

I would guess they are hard wired and the power went off for a short time.  The smoke dectors were trying to let you know they had no power, and all of a sudden it came back on.

Good Luck

Answer 4

I am guessing that your alarms are all hard wired into your electrical wiring?? that would be the only reason they would all go off if there was no smoke. Do they also detect carbon monoxide? Perhaps you should find your manual or call the manufacturer

I am no electrician, but it sounds like it could be an electrical  problem!!!
