(I have carbon monoxide detectors that are not going off)
I have smoke detectors that are incorporated into my home alarm system. The other day, the one by my front door went off for no apparent reason, twice, and when I changed the batteries, it started alarming again immediately.
there was absolutely no reason for it, there were no open windows or doors nearby, it just went off. so, my alarm company replaced it. installed the new smoke detector yesterday and… it just went off again. completely different smoke detector.
there’s absolutely nothing in my house that could produce carbon monoxide, but I have separate CO detectors anyway that aren’t going off. there’s no smell, there’s nothing visible, and these are those electro optical photoelectric style ones.
A ghost 👻
Look for an expiration date. Radionucleotide style detectors end up failing with false positives when they reach end of life. You might need to have all the old ones replaced.
I used the wrong word, but this is a photoelectric detector. The manufacturer date is less than one year ago
Dust maybe? Dust can have the same particles as smoke.
Spiderwebs or insects can mess with the sensors, likewise with dust. Try spraying some canned air inside. Or if it’s a few years old, you may want to replace it.
now there’s an idea. I live in south Florida and my house was built in the 1950s. I wonder if some spider has decided that the inside of this detector is a good place to hide. blowing it out isn’t going to help though, because I replaced the entire detector and if there’s a spider going in there, they just went back into the new one immediately. I’m going to have to set up a security camera on this thing
Mine went off in high humidity when I showered and forgot to turn on the fan
