(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.

Are they networked? Mine are somehow connected and the one that beeps doesn't always seem to be the one that detected the issue.

~~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.~~

Heat or carbon monoxide. Check what type of detector you have, it could save your life
