Having a propane gas leak in your RV is a scary situation that you don't want to even think about let alone experience. But this detector will give you peace of mind knowing that if there are dangerous levels of propane, it'll quickly and accurately warn you and your family so you can get out of the RV and into fresh air.

Hard-to-Miss Visual and Audible Cues

When propane gas is detected, the red LED will come on, and the horn will be constant. And because the sensor is highly selective, it's designed to only sound the alarm for lethal propane gas, reducing the number of false alarms that occur in non-threatening scenarios.

It'll also alert you when the battery is low or when the detector has reached the end of its life and needs to be replaced, so you never have to be without protection.

Easy to Test and Silence

RV Safe Propane Detector

To double check that the detector is operating normally, you can easily use the button on the front to test the propane sensor and battery voltage. You should test your detector every time it's taken out of storage and before it's taken out for each camping trip. This button also lets you silence the horn up to 5 minutes during non-life-threatening situations. So, you can turn off that annoying racket in the middle of the night while you're trying to hunt for a new battery.

Surface-Mount, Bolt-On Installation

The 2 included universal mounting brackets allow this detector to replace 90 percent of all OEM surface-mount and flush-mount detectors. This detector can replace most Atwood and Dometic branded detectors, as well as Safe-T-Alert 20 series, 25 series, 30 series, 35 series, 40 series, 45 series, and 65 series detectors.

Because propane gas is heavier than air, it'll settle near the floor, so this detector should be installed 4" to 18" from the floor to accurately detect the presence of gas. Also make sure that the detector is located in an area that isn't near a window or door, behind furniture or drapes, or in a closet. It also shouldn't be installed with 24" near a stove, oven, fridge, or furnace.

This Propane Detector replaced an old Atwood Protechtor Series 2001 and the larger bezel covered the hole from the old unit. It looks good.


This unit much better than original. Flat design and now my big foot does not bump it being low on the deck! Another happy camper! Thanks etrailer!


Nice detector that does not stick out in the back. This makes for easy replacement of most detectors. It is even made in the USA!


Had to replace my Attwood propane detector at it's 7 year mark and found out that those are hard to find and are not produced anymore. So I decided to go with this one. It was a perfect fit in the original cut out and is nice and sleek looking. Hook up was easy with the 2 wire red/black and testing was as simple as a push of the button. Very pleased with my purchase so far. We'll see if this one last the 5 years it is rated at.


Replaced expired propane detector with this one. Installed easily and has bee working fine.


Received my package very quickly.
I’ve ordered it to replace an existing Gas Detector when the time comes. My current detector is about 5 years old and I want to have the replacement ready. I ordered this model as it has the flange to cover the hole from the older model.


I really liked that this unit came with two different size mounting plates. It made it really easy to replace the old one in our Roadtrek. After a year its worked without any issues.


replaced an atwood with this detector. Easy to install, and small mounting bracket covered existing hole for atwood detector.


Description matched the item perfectly. Installed in less than 10 minutes. The item was delivered well ahead of the scheduled arrival date. Very satisfied.


great price, easy installation. Great replacement for the original.


Easy install. So far so good! Thanks Et railer


Very easy to install. Instructions are clear and test went perfect. Had to install vertically due to the curved wall.


Works great! Exact fit.


Was easy to install and plug in to work.


Definitely will work and the included bezels will cover up the OEM hole.


Much slimmer profile than the RV's original unit. Very easy to install.


Always great service


Good price good quality


Very pleased with customer service and the product. They personally called to confirm an address question and the product adapters insure a great cosmetic fit. Very pleased.

  • What is the Lifespan of the 2-Wire RV Propane Gas Detector
    I reached out to the manufacturer on this and they mentioned that they are required by law to print a date on these units, but they informed me that the 5 year lifespan of the # RS44FR begins when it's connected to the power source. Additionally, this information was provided-"We give an "End-of-Life" signal after 5 years of operation, so the alarm will continue to function normally for at least 5 years after installation." I can see why this would be confusing, and so do they; so hopefully...

  • Can The RV Safe 2-Wire RV Propane Gas and Carbon Monoxide Detector # RS44FR Be Mounted Vertically
    The 2-Wire RV Propane Gas and Carbon Monoxide Detector # RS44FR can be mounted vertically if needed but most importantly should be installed no more than 18" from the floor so that it can accurately detect the amount of gas in your RV. Do not mount this detector within 12" of any opening windows, exterior doors, fans, vents, or areas with a draft. To continue, do not mount on exterior walls, within 24" of any cooking appliances, behind furniture or any areas that would block flow to the...

  • Replacement LP Gas Detector Recommendation For Older Protechtor 2001 Series LP Gas Detector
    I wasn't able to find the Atwood 36720 RV Propane Gas Detector you mention, however I was still able to find the RV Propane Gas Detector # RS64FR in white, or # RS44FR in black to work as a replacement for your Protechtor Series 2001 LP Gas Detector. This replacement will work with virtually any alarm, so it is likely to work with yours as well, and features the same two wire design as your current Protechtor Series 2001.

  • Replacement Gas Detector for an Atwood Series 2001 LP Gas Detector
    I tried finding information on the blinking green light on your Atwood Series 2001 LP Gas Detector but was unable to find anything that mentioned a blinking green light. The Atwood Series 2001 LP Gas Detector you have is no longer available which is likely why it was difficult to find information. The Atwood Series 2001 LP Gas Detector does have a life cycle of 7 years +/- 128 days. This starts once the detector is first started up. If you believe you are close to or passed that 7 year...

  • Replacement LP Gas Detector for a CCI 7770.2 / Pre Tell 22 Detector
    We do have some LP gas detectors available, but none would be a direct replacement for your CCI 7770.2 / Pre Tell 22. From what I could find on your CCI 7770.2 / Pre Tell 22, it has dimensions of 6.25" wide x 3.9" tall. The RV Propane Gas Detector # RS44FR (black) and # RS64FR (white) measure 4-1/4" long x 2-5/8" tall but have two different bracket sizes to fit what you need. Large bracket - 7-1/4" long x 3-3/8" tall Small bracket - 5-3/4" long x 4-1/4" tall
