Has anyone found good smoke/fire/co2 alarms to use onboard? The FirstAlert ones we have keep going off randomly, sometimes in the middle of the night. Maybe due to humidity?

For CO alarms our e36 had wired in alarms. The attached pic shows the replacements we found. Marine approved and work well. No issues or false alarms. One is installed in the salon near the Nav station, the other is in the aft cabin.

Do you have lead acid batteries? Or stored solvents? Are the alarms near them? Outgassing batteries and solvents will cause false CO alarms. I don't think humidity plays a part unless it is actually steam in the air.

Otherwise, I think we have the same combined units as you do, and don't get false alarms (no lead acid batteries and solvents all stored outside living space).

I installed a Fireboy-Xintex CO Alarm several years ago. No issues with false alarms like I had with a unit from a big box store.
