[REDCART]

I searched TOTV but did not find a similar issue. At 2 am all of our 4 smoke and 2 CO alarms went off simultaneously. Six alarms in the middle of the night is unnerving. There was no fire, and our home is all electric, so no likely source of CO. I went from room to room removing the detectors from the wall. When I removed the last CO detector, it caused the remaining alarms to go silent, so I’ll assume that particular CO detector was the cause of our false alarm. Getting on a ladder in the middle of the night is never fun. I also wonder if we were away would the alarms sound indefinitely.

Our home was built in 2015, which makes our CO detectors likely candidates for replacement. I’m also going to replace the smoke alarms while I have the ladder out.

Anyone else have a similar false alarm experience? I’ve had expired CO detectors beep at the end of their useful life but I’ve never had a false alarm like this in my experience.
