Does the fire alarm react to flame only or smoke/dust? Did you have a window opened? If so, could any smoke come through it??

Do you have back-up batteries in it?  Sometimes ours makes noise when the batteries are getting low.  If not, maybe get it checked out by an electrician to make sure there is no faulty wiring.

Maybe an electrical surge? Dust? We had our fire alarms go off a couple years ago in the middle of the night for no reason, only to find out the next day that so did DH’s cousins at the same time! So weird!!!

How old is the alarm? If over 10 years, it could be faulty and you should replace it.

Also, check for dust/spiderwebs on it. Build up can cause it to go off.

It could be the batteries are getting old.  Does the alarm test for carbon monoxide too?

@fivemonthsnotice:   That’s really strange.  Now that you mention it, ours “chirps,” too.  I’ve also heard that dust can cause it, as PP’s said.  Maybe it’s defective or worn out?

Any thunderstorms in the area that could have knocked the power out and back on?

Did you guys have any rain or anything last night? When I was in college, one of our smoke detectors kept going off in the night, and when we pulled it out of the ceiling, a bunch of water came pouring out of the ceiling, too. We had a small leak in the roof above our apartment, and the water pooling in/near the smoke detector caused it to go off.

My parent’s fire alarms would go off sometimes in the middle of the night and it always scared the crap out of me.

I don’t remember what they did to fix it, but they tested the house for carbon monoxide.  It didn’t fix their problem as there wasn’t a high level of carbon monoxide in the house, but checking your house might be a good idea!

It could have been from moisture as well. We have a fire alarm in our finshed attic at my parents’ house, and sometimes during storms, some moisture will get in there causing the alarm to go off in the middle of the night.

Like other PPs said, it could also be from dust.

OMG Mine did that a month ago– at 2 am!

Nothing like a half asleep fog of ear piercing madness!!!!

We did the same thing, and a few mins later they went crazy again.

My honey just took them down, we removed the batteries and have been stumped ever since. My boss told me the batteries were low and that’s why they went nuts.


I have new batteries now, but haven’t installed them yet…. I don’t want another middle of night heart attack unless it’s the real deal….
