Where is your Carbon Monoxide Sensor mounted??

[jonnys_walkers]

DW's son and his family did some driveway camping recently while visiting.
He notice and brought to my attention where the Carbon Monoxide Sensor was located. It is about three feet above you head on the front wall while lying in bed.
I was always taught that Carbon Monoxide was heavier than air. We would be dead before the sensor goes off. This came from the factory like this. Now there will be screw holes in the wall when I remount it.
I think I will notify the factory and inform them they are mounting the sensors in the wrong place.
Check yours and make sure mounted at or near the floor.

Ours CMS is located on the ceiling in the bedroom area. Our propane detector is located at floor level. Carbon monoxide is a gas lighter then air, so having the detector up high is safer then at floor level.

Sorry, but you are wrong. Carbon Monoxide is lighter than air. Having the sensor mounted as high as can be is the correct place for it. As for being above your head,while in bed, may be a good location, ours is on the wall, opposite the stove, as high as it will go. The stove is the only thing inside that should produce any carbon monoxide. Water heater, furnace, all have access to outside air for burning and exhaust outside.

nope, CO is lighter than air. it's the propane that's heavier. that's why the CO detector is high and the propane detector is low.

from Wikipedia:

Carbon monoxide (CO), also called carbonous oxide, is a colorless, odorless, and tasteless gas that is slightly lighter than air.

Believe it or not the RV code allows dual use CO/Propane detectors (yea, I did not believe it myself).

They are located at floor level.

They work great for early detection propane. For CO? Not so much.

Don't confuse a CO detector with a SMOKE detector. While they also can be dual use, smoke detectors MUST be located either on the ceiling (no closer than 4 inches from a wall) or on the wall a maximum of 12 inches from the ceiling.

I have a dual one. It goes off for nothing.

At sea level and 20*C...

carbon monoxide is 1.145 g/L
ideal air is 1.2 g/L

Carbon monoxide is slightly lighter than air. The difference is so slight that natural convection currents keep it mixed.

Mine is mounted at the ceiling next to the smoke detector above the stove.
Lpg detector is mounted at the floor by the bedroom step.
I just got done putting batterys in all my remotes and detectors and air mattress pump.

WOW 40 BUCKS for all them batterys.....
