Sleep soundly in your RV knowing that your family will be better protected with this accurate propane and CO detector. When either gas is detected, an LED and a loud horn immediately alert you so you can get to safety more quickly.

Specs:
Having a propane or carbon monoxide 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 either, it'll quickly and accurately warn you and your family so you can get out of the RV and into fresh air.
When carbon monoxide is detected, the red LED will flash, and the horn will blare 4 times. When propane gas only or both propane and CO are detected, the red LED will come on, and the horn will be constant. And because the sensors are highly selective, they're designed to only sound the alarm for lethal gases, 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.
To double check that the detector is operating normally, you can easily use the button on the front to test the propane sensor, carbon monoxide 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.
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.

Ratings & Reviews
It was an easy upgrade from the 10 year old propane detector. The included face plates made for a nice look.
Easy to install and peace of mind knowing both propane gas and CO detector is in place.
Perfect replacement for 2016 Lance 865 camper. Lined up with existing screw holes. Very easy DIY fix. Seems to use less battery power too.
Exact fit replacement for our original propane/CO sensor. Easy installation in our unit, works great. Our original sensor started going bad about a year early and would start chirping in the middles of the night.
Exact match replacement
Perfect replacement and easy installati on.
works as described
Nice to have the additional plates to cover up old screw holes
With the large cover plate, everything was a perfect replacement to OEM part.
I haven`t installed the carbon monoxide detector just yet, but I`m sure it will be just fine & will work as intended. I`ve never had any issues of any kind with any product I`ve purchased from etrailer & will always do business with them. They`re great ppl & extremely easy to work with.

Thanks Robert, we really appreciate your business!!!
Everything I have purchased from ETrailer has been great. Thanks
Exact OEM replacement for our rig. Little more expensive than competitors. Shipping was good. Actually arrived a day earlier than expected.
This will be installed Friday. As always eTrailer very helpful and easy to work with.
Excellent product! Perfect fit replacement with the included adapter plate.
The RV Safe propane gas and carbon monoxide detector was a perfect replacement for another model that came with our RV. The trim back plate covered holes that were there nicely. Easy to install, two wires connected to existing 12V wiring with wire nuts, 4 screws and done. It tested out perfectly. So far there have been no false alarms (big plus). Packaging and delivery was perfect.

That is great to hear! I am glad you got it quickly and the installation was a breeze. How often are you able to get that Airstream out?
Looking for a replacement for original CO & propane detector. Works great. Easy replacement with two different size trim plates included to choose from.
Received this yesterday and installed it immediately. The dual mounting plates are a big plus, and the smaller plate worked great for our Airstream. Very happy with the purchase, quality, and ease of installation.
Fast shipping, easy to wire in and good replacement for old detector
This was easy to install and fit the space of my old detector that had aged out. I appreciated having two trim pieces to work with. As usual, etrailer service and shipping was excellent! I really appreciate the effort they put into everything they do!
My order arrived quickly. This sensor was an exact replacement and worked great. Very happy with my purchase.

That is great to hear! I am glad you got it in time and it was a direct replacement. What kind of trailer did you install it in?
Thanks for reaching out George. Sorry I didn’t leave a review one year ago. Can’t believe time flew by so fast. This product is operating just the way I expected, looking forward to not replace this product for years to come.
So my factory sensor started to act up, and I read the reviews and let me tell you the reviewers know what they’re talking about! So here’s a pic of my original one, and of course my new replacement

Hey Ron! Happy to hear that the sensor is a good replacement to your factory one! What kind of camper do you have?
I recently learned that there's an expiration date printed on these devices, so I checked mine. Two years out of date! I ordered this and it's the perfect replacement. Installation instructions were clear, making it easy to swap out the old one. As always, eTrailer delivered as promised.
Easy replacement for Atwood 31013 RV Propane detector in 2018 27’ Airstream International. Fits in existing hole, just had to drill two small holes for new mount. This new detector does carbon monoxide in addition to propane which I appreciate.
I bought a replacement CO/propane detector; last year on line. It failed after 1 year. The unit I bought was supposed to be the "lastest" model. It was a knock off. There are certain RV items that you should NOT buy from large generic market sites. CO/propane detectors is one one them! This was a drop in replacement. It is "LOUD" but so are my home smoke alarms. Peace of mind is key!
Easy installation. The larger of the two mounting plates is the same size as my old unit. Even the mounting screws align with the old screw holes. It's flush mounted so nothing but the two wires extend through the panel. And it's made in the USA! Well done.

Glad you like it, Bob! Gotta love when things fit like they are supposed to and are American made! ^___^ Was the unit you replaced an Atwood by chance?
Do you have a question about this RV Gas Detector?
