(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.
UPDATE: so they kept sending me the same model of smoke detectors so I didn’t remove the old bracket, I would just mount the new detector in the old one. well, today, I see a moth larvae crawling out from behind it. I take the bracket off, and there we are; two moth nests. I think we’ve discovered the issue
