Replacement Propane Gas Detector For CCI Controls 7719

Updated 03/30/2026 | Published 03/24/2026

Question:

I need to replace a very old CCI Controls 7719 3-wire LP Alarm with solenoid valve control. My preference would be to simply bypass the valve control need to ensure the valve remains open and use any of the standard 2-wire detectors. Your recommendation? TIA Mitch

Hey Mitch! You can use the RV Propane Gas Detector - 12 Volt - 2 Wire - Black # RS44FR to replace your existing detector. However, you will need to remove the old detector and valve, then reconnect the line with the appropriate fitting.

There isn’t a reliable way to bypass the old setup long-term. That valve is normally closed and requires constant power from the detector to stay open, so simply removing the detector would shut off your propane flow.

Where are you headed next with your Dynamax once you get the detector replaced?

I wouldn't bypass it unless for a temporary situation. The replacement couldn't be easier to install

Just replace the detector. Very easy, just be sure to mark your wires before disconnecting so you hook up the new one properly. I took a picture before I got started. Ez pz.
