what alarms on Mountaineer

[twindman]

I know there is a propane detector by the stove, and in my hall there is a smoke(?) detector. And above my bed is another detector. Is it also a smoke detector or CO2??? I need to replace the missing one above the bed. Thanks.

In that position we use a Kidde combination smoke and CO2 alarm. I think we got it on Amazon.
