We are on the road for next couple of weeks. This is fourth night in our 2004 Fleetwood. Every night carbon monoxide monitor is the bedroom beeps after we are in bed for at least couple of hours or so. This is just single beeps. The monitor in the living is functioning fine light is green. These are single beeps with few minutes intervals. I am running all appliance on electric water heater and frig. I stop the beep by pushing and holding down the button for couple of times. Any ideas? no batteries

These have a life of 5-7 years. There should be a date on the back of it. It's time to replace it. I got a replacement from FW recently.

When you say "no batteries" I assume you mean it is hard wired to the 12 volt system. However, some hard wired alarms still have a back up battery in case of a power failure. The other reason could be that the alarm has reached its end of life date. I bought a combination smoke/CO alarm recently and it has a 5 year life span on the label. It will beep a certain sequence when it needs replaced. If this alarm is the original one on your 2004 coach then its 9 years old.

Edit: Cliff beat me to it on the expiration date!

Verify. Our front detector is a hard-wired LP detector on the kickboard under the cooktop. On the ceiling is a 9v battery smoke detector. In the bedroom is a hard-wired CO detector (neither hard-wired are battery backed up). I made the mistake since ours was beeping that I needed two units. Turns out, 2 mistakes. 1)Only one CO (other was LP although they look simiar at a distance). 2)Although they were both beyond their 5-yr life expectancy, it was beeping due to low voltage. My CO was wired to the Chasis batteries (around the storage shutoff switch/relay so it was still powered). My chasis batteries were drained to 8.4v as the solar, generator, converter and alternator all charge the house batteries but only the alternator charges the chasis batterys. Learning more each trip.
