(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.

Sorry, trying to follow here. Three locations: front door, kitchen and living room. 4 detectors: original front door, new front door, kitchen and living room?

Original front door went off in situ and in the living room while holding it?

New front door went off at front door. Swapped NFD with living room - NFD went off in living room.

Moved NFD to kitchen and it went off in there too?

Where are the K and LV detectors now? Have any of those gone off anywhere in the house? Are THEY functional? (Sorry if you already said, I’m trying to piece the bits together and mighta missed that)
