So sorry to LOL,,,,our boy was sleeping right next to the detector and let one go.....he slept right thru DW having a heart attack trying to find the leak
Once she moved the fir butt the alarm calmed down,,this happened twice in the last week
. We had one that used to chirp every so often never really found out why. Have you introduced a new air freshner that has a strong smell.
We also had our Freightliner's fumes get in the trailer and set it off...wind was just right when we were getting ready to move. Does the neighbor stink???? Been with a few carnival trailers....well we will just leave it at that
Hope you find out the problem quick....I know how that particular sound can drive you
