carbon monoxide alarm - help

The CM alarm continues to beep. I have changed out the appropriate batteries, and it still beeps. What do I do?

  • Those alarms are also hard wired to the 12 volt side of your RV.

    Beeping means 'low voltage'.
    Check your coach battery.
  • My goodness, what a great forum site this is! To those of you who replied, I do so appreciate the advice. I didn't know CM units needed replacing. I thought it was just the batteries. Thanks again.
  • Buy a new one
    They only have a 5 year life and that may include shelf life Not that expensive considering your life. Whats it worth? More than $15/18 bucks? Plus the fact that in an RV it's exposed to more CO than in a home because of the travling on the highways with all the other fuel burning stuff out there
  • Check the expiry date. Yes they du expire and will beep and alarm when its time to replace..
