what invisible thing could set off my smoke detector? (lemm.ee)

(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.

~~Sounds like a bad unit, try replacing it. The fact it’s going off elsewhere and no other detectors go off says it’s the unit.~~

I missed that you changed units, check your wires.

If the new unit starts going off, you may have a switched wire between your signal (red) and your hot (black) that fried the unit.

it's not hardwired, my security system is entirely wireless

Then some signal from the base unit alerts all units that one detector has gone off, to alarm the home. Either the base unit is sending a false signal, or some outside signal is mimicking the signal.

Personally I’d install a standalone detector in that spot.

I'm slowly concluding this might have something to do with my Ring Doorbell and a new Chime I've added to that system, or cobwebs. I've thoroughly dusted this corner of the wall and ceiling now, and the chime stopped working anyway so
