Co2 alarm

[drb1984]

So here's my 2 week old 26rr that hasn't even been used yet sitting in my driveway and the co2 alarm goes off and stays in. Nothing is running, propane is isolated...I don't get it. I owned up all the windows and let her air out and it went away but not sure why it came in

Give us some info:

Is it plugged into AC?
Inside temp?
Coach battery run down?
You say propane isolated, do you mean turned off?

[drb1984]

No not plugged in currently, battery was run down, inside temp was probably about 78. Propane is turned off

may have just been low voltage . charge battery , keep plugged in if you do not the co2 and smoke and a few other items will drain the battery over a short amount of time

Low trailer battery will trigger alarm, since it's hard wired to the battery.
Either keep trailer hooked to shore power or install a battery disconnect switch.

The CO ( Carbon Monoxide) detector is powered by the RV battery and is designed to alarm if the voltage is too low. As mentioned, if you do not have the RV plugged in the battery will be drained by parasitic loads ( CO detector etc). You need to keep unit plugged in or add a battery disconnect switch to eliminate the parasitic loads.

Ok. Thanks guys

Thanks for this question and answers, this is exactly what happened to our unit this morning. We did not know the CO2 was hard wired directly to the house battery.
Yes, our house battery is low.

So grateful for knowledgeable people on this forum.

Another reason, since it is also a Propane sensing alarm. My old camper had problems when it was first new. The propane alarm would go off, and the propane was off and I could not smell anything. I contacted the dealer and they told me it might be sensing the solvents, chemicals used for the sealants. They seal all the seams etc. as part of the dealer prep. I noticed my new camper had that done too. Might be that, if you can open up a window to let it air out.
Several months later, I bumped the knob on the stove releasing propane into the rig. And the propane detector, of course, did not go off...

Just to be clear in case you go to the dealer, it is a CO, Carbon Monoxide, detector, not a CO2, Carbon Dioxide, detector. CO can kill you and is serious. CO2 usually makes you happy, as that is what makes soda and beer and other carbonated beverages go phsssssh when you open them. The best CO2 detector is my wife as she hears one too many beers opening and tells me, "you're going to kill yourself!" Have a short winter. Spring is around the corner and can't get here soon enough!
