And no there is no fire and I haven't been cooking
The one in one of the bedrooms keeps setting off all the others since they are all wired together. There is no sign that anything could be setting it off, and they are not CO detectors, I have 2 separate detectors for that. I have had no low battery indicator sounding recently either. This has happened several times today and it is starting to make me nervous though! Anyone have this happen?
