Atwood 3-wire Propane and CO2 Alarm Replacement?

[Dirt Duff]

The detector in my LE2 needs to be replaced.   It is a 3-wire Atwood model # 36636.  Atwood is out of business.  More recent revisions (model # 31011 and 36681) can be found on EBay but I wonder what others are using as 3-wire replacements.  What is Oliver installing in new trailers?  Has anyone found a replacement 3-wire detector?

"What is Oliver installing in new trailers?"

Our Hull #1291 (2022) Elite II has an RV Safe Co and Propane Alarm.  See photo.  It appears to be smaller than your Atwood, and installed differently.

Thanks Rivernerd.  Looks like Oliver in now installing 2-wire alarm.  The 3-wire version of your alarm (model RVCOLP-3) is also discontinued and not available anywhere.
