  • 4 things come to mind:

    If stand alone unit, either the internal battery is dead/low or the unit itself has gone bad. They DO wear out.

    If hard-wired, check the voltage of the big batteries, the output of the converter could be low or non-existent. Or, the unit itself has gone bad. They DO wear out.
  • Low battery on mine detectors give small beep, while CO gives constant alarm for reference.
    Other explanation might be neighbor idling his engine.
  • what year is the camper? Our CO detector went bad and we had to replace it. When it went bad, it beeped.

    About the only way I can think of to test for CO is to put a canary in the camper and see if it dies.

    Don't let the animal people (PETA) see this post. :E

    Maybe the OP should check his battery voltage first.
  • Two things: Low voltage, or carbon monoxide.

    Just because it's plugged in does not mean the converter is working correctly and providing power to the detectors. They could be pulling off a slowly-draining battery.

  • are you sure it was the carbon monoxide alarm going off and not the propane sensor?
