Replacing 12V Propane Gas Alarms in an RV or Trailer

Question about replacement 12 volt propane gas alarms for a motorhome.

Q:" How do I choose the correct 12 volt propane alarm for my motor home? The brand that was in my motorhome is no longer available?" Thanks. Joe

Answer: Currently, we are selling Safe-T-Alert propane alarms, USA manufactured, that meet all RV standards. Unfortunately, we are unable to locate a manufacturer that sells a unit with the third wire, that one that closes the propane gas valve if a leak if detected.

Choose a unit by answering these questions:

Is the current propane alarm mounted flush with the wall? If so, measure the opening. The units we sell are:

  • 30-442 (Flush Mount)Case Dimensions:6.375"W x 2.875"H x 1"D
  • 40-442RV Flush Mount Gas Alarm: Case Dimensions Recessed portion = 3"H x 4"W. Depth = 1 1/8". Flush mount portion = 4"H x 4 7/8"W. Screw Holes = centered, 4 1/2" apart.

Is the current propane alarm surfaced mounted, ie. not flush with the wall?

  • 30-441 (Slim Line Surface Mount): Case Dimensions: 6"W x 1.875"H x 1.5"D
  • 40-441RV Case Dimensions: Bottom (where mounted) = 3"H x 5 3/8"W. Top = 3"H x 5"W. Depth = 1 3/8". Screw holes = centered, approx. 5" apart.

Do you want a brown unit?

  • 40-442A-BR is chocolate brown and a flush mount. The 40-441A-BR is the corresponding surface mount unit.
  • The 30-441A=BR is the chocolate brown surface mount propane alarm and the 30-442A-BR is the chocolate brown flush mount model.

What is the maximum amp draw you want?

  • Both the 40-441 and 40-442 draw 46 milliamp (0.046 amp.)
  • The 30-441 and 30-442 draw 76 mA. This 30-442 can replace the CCI-7770 Propane Alarm that is discontinued.

The warranties are longer on the 40 series units. If you are interested in the product manuals, we have them listed below the pictures of each product.

I hope this helps answer your question. We do recommend that you test your propane alarms and your RV carbon monoxide alarms at least once per month.

Sincerely, Barbara
