LP only alarm with safety shutoff

[Dodge Guy]

OK, so it's well past time to replace the LP/CO detector in the Georgetown. Mine has the safety shutoff solenoid to shut off propane in the event of a leak inside. I want to replace it with an LP only alarm with auto shutoff but incantation seem to find one. Has anyone Donne this ? I have a CO smoke detector in the bedroom so I'm covers there (actually better since CO rises).

What I currently have is a Safe T plus 70-742 R.

Ok. Got my new LP/CO detector yesterday. Installed the detector in the same spot it was in. I have the new solenoid, but can’t install it until I move the MH over, the tank door is up against my retaining wall. I will try and install it tomorrow before I leave for the weekend.

Thanks again.
