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.

Hard-to-Miss Visual and Audible Cues

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.

Easy to Test and Silence

RV Safe Propane and CO Detector

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.

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.

Average Customer Rating:  4.8 out of 5 stars   (278 Customer Reviews)

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.


The detector installed easily and was quite invisible/flat against the wall. I tested it with an unlit propane burner and also with 2 large garbage bags filled with car exhaust. Both worked perfectly and we now feel more at ease when going to sleep, knowing that we will be warned in the event of a propane or carbon monoxide exposure.


Excellent replacement. Nice that a couple cover plates are included to cover preexisting cutout.
Easy ordering and quick delivery by etrailer as always


Placed order on Monday product received on Thursday. Installation was easy only needed use of a bottle jack and socket wrench. The ride was improved and side to side sway in windy conditions is much less. Test conditions wind 15mph with 30mph gusts.


Great item for the price and EZ install. Replaced old faulty unit that would go off all hours of the day and night with this low profile unit. Tammie at etrailer was a great help with selecting the correct item with fast and free shipping.


Easy Peasy Lemon Squeezy! After 6 years, Atwood detector finally decided it was done. Found this little number and was so easy, I was done in 5 minutes (most of which was finding a pair of pliers). Cross my fingers it never detects anything but feel much better that we have a working one now.


Great product and easy to install, we are happy with the detector!


This unit was easy to install and works perfectly! Highly recommend as a replacement for original from factory.


Great customer service from initial order to delivery!! Detector/alarm arrived several days early and in great condition... Good instructions and easy to install... Alarm was tested and is working as designed... Great experience all around - Thanks!


This detector worked perfectly as a replacement for the original detector in my 2019.5 LTV Unity MB24+.


Arrived when expected and exactly as described. Perfect fit replacement. Thank you.


This is a replacement for a bad alarm. Only thing that kept it from a 5 star is that I had to get a white color replacement instead of the black color.


Does what it is made to do


Great price and great product


Fits over the old recessed hole. Looks great.


Quick delivery in safe packaging. Perfect fit, no plastic adaptors needed. Worked as intended. I trust E-Trailer.


Slim and nice fit.


Good product, arrived quickly and on time. Ordering was easy and fast. upgraded shipping at no additional charge. will use again. New to RVing.


An overlooked aspect of RV ownership, update these on a regular basis.


The original propane detector in our camper is now obsolete. This model fit over the original cut out. Looks clean.


Received unit that came with two adapter covers to fit existing hole. Hooked up and worked right away. Simple instructions and good looking piece of equipment. Arrived on time, thank you.


Very compact design that fit perfectly in its designated space with one of the two adapters provided.


Perfect for what I needed


This was a great replacement for the failed Atwood model that was installed.


Easy installation. Rar instructions.
made, exactly as described.


Inclusion of two mounting plates, one square-ish and the other more stretched out allowed me to pick the one that filled the hole left by the old Atwood it replaced. Functionality is good, but only 5 yr lifespan is a little disappointing.
