(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.
They are probably both about the same age and need replacing. Smoke and carbon monoxide detectors have a finite lifespan, no matter how often you change the batteries. Fortunately they’re not all that expensive, just get new ones. I had the same problem in my apartment last year, and the carbon monoxide detector was over 10 years old. So they just replaced it, problem solved.

Nice theory but it’s disproven by OP’s initial text
I had trouble with them going off in humidity, they were past their expiry date so replacing them fixed the issue.

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
