(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.

    I think you said elsewhere that they are new and that they are photoelectric rather than the radioactive ones.

    I’m purely taking a shot in the dark but I’m wondering if you should try sealing up the hole(s) in the wall that you made to run electric and to mount the detector

    My thinking is that dust might be getting caught up in a tiny draft through that hole and it’s so close to the source that it sets it off. Cause like, if wind hits the side of the house, there can be some positive pressure in the crawlspace which often also means inside the walls.

    I guess maybe somehow there could be some stream or condensation as well. If it’s right by the front door and the humidity is high, maybe the hot air from outside meets the AC air and causes a tiny amount of condensation. Or if you live in hellscape temperatures, maybe there could be some vapor generated because of the hot air.
