Carbon monoxide alarm

[Off The Grid]

We were docked at our marina plugged into shore power when one of our carbon monoxide alarms went off in the guest cabin. We have had this happen before when anchored in a bay overnight and the house batteries died. It has never happened when plugged in. Any suggestions for why this would happen or how to fix it?

It's a low battery voltage warning. Think of it, the detector would do you no good, if your battery died. Even though you're plugged in, that doesn't mean your batteries are charging sufficiently, or holding a good charge. You will want to check them, for starters (no pun intended).

Was a boat nearby running its generator or engines? Could have been actual CO from that as well.

Check you battery water level as the fumes can set off the CO detector.

Thank you both, Seatech is where I was leaning too. I took a picture last night and all I can see printed on the fitting is "INCH" and "15mm"
