CO2 detector

I have had mine trip when there was a lot of dirty exhaust from another vehice and one time from the exhaust of a forklift that was near the camper. The monitor cannot discriminate as to the source of the CO. It could even occur from being downwind of someone's barbeque or generator.

Buzzcut, you're right of course, but don't tell the global warmers that:)

There are no CO2 (carbon Dioxide) detectors. CO2 is what you exhale after each breath

There are CO (Carbon Monoxide) detectors. CO is from incomplete combustion and will block O2 from binding to the hemoglobin in your blood and kill you.

Sorry it took so long to get back, and I appreciate all the tips.
I just learned something: It's NOT a CO2 detector, It's a PROPANE detector, and yes, it's down by the floor, so I'm going to be doing some checking. It's down by the floor for a reason, propane is heavier than air and it pools, so maybe I've got a propane leak. I just wanted to pass on the tip that the one by the floor is NOT a CO2 detector. Thanks again guys.

Mine gave up the ghost after 2 years of use. I put a switch in the new one's power line so that it's only on when we need to depend on it. Did the same with the propane detector. These things are vAMPires needlessly sucking up power when you're not occupying the camper. Of course, we are now taking full responsibility for our own protection. But then, we feel that we are responsible adults and can look out for ourselves. -Mark.

While it might be only 1-1/2 years since you installed it, it may be much older than that from date of manufacture. Carbon monoxide alarms do have relatively short useful lives from date of manufacture. So if you are sure it's got proper power, constant false alarms mean it is used up, time to replace with a new one.

Had to replace mine in the t/c. Was 5 years old. Expiration date was right on the front of the unit. Bought a new one and now no false alarms.

Carbon MONoxide (CO) detectors do come with a shelf life, it should say something about a "replace by" date right on the unit itself.

Is this the detector on the floor? My old and nearly deaf dog when lean against it while sleeping. He kept pressing the test button. Of course it didn't wake him.
