CO monitor issues

I'm getting an alarm from my monitor when it's out of the water at home on the trailer. My batteries are fully charged, so I don't think that's the issue.

I thought it could be the butane canister leaking, so I removed it, I know that butane isn't CO, but anyway.

The alarm still goes off! Could it be the monitor itself?

Any ideas?
 
I had my monitor go off once when a cloth bag was up against it. I don't know if that is a safety feature or how it could tell that something was up against it, but it could clearly detect more than just CO.

A couple weeks ago I was idling downwind and could smell my exhaust once in a while. After a few minutes the CO monitor went off. I guess I should take the exhaust smell more serious.

Batteries fresh? Even when I've thought new batteries were fresh, I've found out by putting them in a smoke detector that they weren't up to snuff.

How old is it and which make and model? I consider them disposable after a couple of yeats If under warranty, return for replacement, I like KIdde Co and always felt they stay behind theri products.m2cw
 
The magic in the CO detector runs out after awhile. Something like 5 or 10 years, depends on the model. When that happens the alarm will start making noise and you can't cancel it, at least with the Kidde one I have.
 
My CO alarm went off several times this year while on shore power at my marina. I never could figure it out. But it scared me; its an eerie feeling the first time you hear it and you're sleeping!!
 
I have had my CO alarm go off a few times. Glad for that, and never when I was sleeping, Glad for that too. :wink:

First question. How old? Most CO alarms have an End of Life alarm, and it cannot be reset or turned off.You have to take the batteries out. I had to deal with that one afternoon at the dock in Reid Harbor. I have had it go off at the dock another time, because some goofball set hes Honda 2000 generator on his swimstep, turned it on and left to go for a hike. And Yes, I was just aft a few feet, downwind, and sitting in my cockpit when he did it. AND NO, I did not give his generator a swimming lesson :shock: , but I was tempted.

I have had a couple of times when doing slow cruise, with the cabin door open and a light breeze, most from behind, and I only had my Starboard window open. Didn't smell any fumes, but did open both the center and other side window and it cleared in a couple of minutes.

The CO alarm gets new batteries every year at the beginning of the season, and it gets replaced ever 4 years since I had the EOL alarm situation and had the rest of the week to be out (without a CO alarm).

So far the only time my CO alarm has gone off is when the house battery gets low (sometimes happens if we anchor out and the refrigerator is being used). I have two, one on the house battery and one on internal batteries.
 
Thanks for the input.

My house batteries are new, and The charge monitor shows 100%. The CO alarm is 9 years old, so it sounds like I'll be getting a new one.

Thanks again Brats
