carbon monoxide

If I read the posts correctly, they're both CO detectors. One is run off the house battery, the other off a regular 9V.

Both were going off.

Either it's an odd, unlikely coincidence that both the house battery and 9V died at the exact same time, or there's CO in the camper.

I am very curious what the OP finds.

Bingo!

I'm sure one of those alarms is a propane leak detector.

Bumpyroad,

Your probably right. But I wasn't going to bring that up.

He said "in her sleep" and my wife told me that females never do that, only males.

Sorry, didn't mean to hijack this thread. Back on subject.

sure, blame the dog.

We've had several things set off the CO detector. It seems to be quite sensitive.

Lysol disinfectant, spray paint fumes, Easy Off oven cleaner, and insect spray. Low voltage cause a slow beep. Makes you wonder if it works with CO.

These also set off the gas detector. I've checked this one and gas does set it off.

Lucky I don't have a dog.

It's definitely not a power/battery issue if two separate detectors with two separate power supplies were both going off.

Somehow, CO got into your camper and set them off. Tread carefully because CO will knock you out before you even know something is wrong, and anyone that comes in after you to rescue you may also be overcome.

It could have been the truck. Just because the alarms didn't go off immediately doesn't mean anything. Fumes don't travel instantly. It might be an hour or two before enough fumes infiltrated the camper to set off the alarms. For that to happen, though, you'd need some sort of ventilation pulling the outside air into the camper.

Strange it is a 2015 AF990 I have had about 1 yr the hard wired detector and the battery 1 I installed were both going off. nothing is turned on not even the heat in the shop. battery shows 13.1 volt. I had run a truck in the shop about 12 hr earlier and nothing happened.anything else set of carbon monoxide detector like sewer gas battery gas ect.
