We looked into every corner of the house, no smoke, no fire. Hubby checked the attic to verify that the furnace was okay.
7 1/2 hours later, still no smoke, no fire. We dunno what the hell happened.

Sometimes they get flakey over time.

Hubby hit the reset, it took 2 minutes to for them shut off.
New sound: after the reset and before silence, there was another sound that I can only describe as an old fashioned telephone busy signal: 3 buzzes, one beat of nothing, then the 3 buzzes repeated. It was impossible to localize the new sound.

I just googled it and the 2 main reasons for false alarms are dust and old batteries. The 3rd most likely reason is old smoke alarms.
We are going to fix the first 2 by dusting the inside when we put in new batteries. I really don't want to get new smoke alarms.

(296 posts)IIRC eventually they will just blast until the batteries die. - which is a long time.

(7,809 posts)Hubby has changed the batteries in 4 of them, hit them with canned air to get rid of dust, and reset.
Crap crap crap!

So you might just have to replace all of them.

(15,806 posts)I was working from home (pre-pandemic) and Dh had just left to bike to his office. The smoke detector up in one of my boys rooms went off. Hmmm. Ok, no fire. Hit the button on the detector, chalked it up to randomness.
15 minutes later, the one in the basement went off. Sigh. Ok, then I understood what was happening. Theyre all hardwired and we put them in on the same day.
So when we replaced them that weekend, we replaced alllll of the hardwired ones in the house (which is most of them) so that when those go, they all go at once.
Except for the one in the hall outside the main floor bathroom. That one malfunctioned after a few months (the sensor on it read the humidity as smoke) so we replaced that one with a more appropriate detector.
I love those things and yet hate them all at once.
