CO detector beeping

I have not completely removed it yet it is hanging from the wires still beeping. The coach is parked at the rear of our property under an RV cover. I bought a battery powered one to replace it I just need to cut the old one in the clear they did not leave enough wire to unplug it:M

Ours beeped when it "expired". It started at 1am and beeped about every 5 minutes! We got up and and took if off the wall and replaced it the next morning with the same thing.

The coach is in storage and not in use but I keep hearing a faint beep I removed it thinking it needed a new battery but it is hard wired. The coach is plugged in and there is nothing running that should trigger the alarm I am guessing it has gone bad. I need to get it fixed we will be using the coach staring the 22nd of this month. The existing detector is a Costar brand.

Should I get another one that is hard wired or a battery operated model?

I don't know where you're located, but It may be too cold for the detector to work properly. Most CO detectors only work within a fairly small temperature range. The widest range I am aware of is from +40*F to 100*F. More often it's +50*F to 100*F

We have one at the family cottage that needs to be unplugged during the winter months. If the temperatures go below 50*F a red light comes on and it starts beeping.

I was in a recent continuing ed. class for my trade license and a guy who seemed to know a lot about smoke and CO detectors had some interesting info. For the CO detectors, they start to lose effectiveness after just a few years and by 5 years they should be replaced. This seems especially important given the confined space of an RV and the cold temps the detectors are subjected to.

I personally put both smoke and CO detectors in each area (where doors can close) in my RVs.

I checked the date it is a July 2009 so I guess it has lived out its life. The battery charger is on so it is not a battery issue. Thanks Mike

Some beep because they are old and tired
Some beep because they are hungry and the battery is low

Since yours in in storage.. I'm going with option 2.
Crank up Generator for oh say six hours or hook up to shore power (same time).

It is stored at my house and hooked up to shore power all the time.

Our first one lasted that long but I don't think they last that long anymore or at least, I think they have something in them that makes them age out at 5 years now. The last two I bought seem to die at EXACTLY 5 years.
I'm trying a little experiment with out new trailer. I'm going to disconnect it in the off season (about 4~5 mos a year) and see if it lasts long than 5 years.
