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


RV Safe Detector Installed

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.

  • Propane Detector Replacement For Older Atwood 33535E
    Hey Justin, The propane detector by Atwood is no longer available, even with Dometic. The best option for a replacement I recommend is # RS54FR, this is a propane and carbon monoxide detector. If you are just looking for propane I recommend # RS44FR as a replacement. This may not be the exact size as your original detector, so you may have to use something to fill in the gaps of the mounting hole if needed. It comes with 2 mounting brackets for different size openings. The smaller being...

  • Recommended Replacement For An Atwood Propane Gas Detector 31013
    Hi Brenda, The Atwood 31013 unfortunately has been discontinued so you'd need to go with a completely new LP gas detector. We have a couple of surface mount style detectors that come with trim rings that will cover the old unit's cutout hole so you won't have any ugly gaps to try and fill. They can come with either just LP detection or with Carbon Monoxide detection as well; and can be purchased in either white or black. Propane Gas Detection: White # RS64FR Black # RS44FR Propane Gas...

  • Recommended Replacement For An Atwood 33535E RV LP/CO2 Detector
    The closest option we'll have to your Atwood 33535E LP/CO2 Detector is going to be the RV Propane Gas and Carbon Monoxide Detector # RS54FR that you were already looking at. It comes with two mounting plates to try and eat up some of your old cutout hole. The dimensions are as follows: The long plate measures 7-1/4" wide, 3-3/8" tall and hole to hole measurements of 6" (center of hole to center of hole) The short plate measures 5-3/4" wide, 4-1/2" tall and hole to hole measurements of...

  • Does the RV Propane Gas and Carbon Monoxide Detector 5 Year Lifespan Start at Install?
    Hey Jeff, thanks for reaching out! Yes, if you buy the RV Propane Gas and Carbon Monoxide Detector # RS54FR right now in 2025 and install it, it will last until 2030. Did your last detector go out, or are you just looking to get your RV ready for camping season?

  • Troubleshooting/Replacing The ProTECHtor LP Gas Detector
    The first thing you will want to do is try resetting the detector. This can be done by holding the test button. If the Red alarm light is still on after a reset, and there are no gas leaks, it is going to be time to replace the detector. They generally last around 7 years so it is not uncommon for them to go bad. Our best option for replacing the ProTECHtor LP Gas Detector is the RV Propane Gas and Carbon Monoxide Detector part # RS54FR. This will be a nice upgrade as it can detect Carbon...

  • Replacement Carbon Monoxide Detector For An Atwood 33535e In A 2019 Grand Design Imagine 2400BH
    Hi Doreen! We have been getting quite a few requests for this as it is getting to be about the time the Atwood detectors need to be replaced. Unfortunately, Atwood isn't around anymore, but we still have you covered. You will want one of the two I have listed below: RV Safe RV Propane Gas and Carbon Monoxide Detector - 12 Volt - 2 Wire - Black # RS54FR RV Safe RV Propane Gas and Carbon Monoxide Detector - 12 Volt - 2 Wire - White # RS34FR Other than the color, these are the same part....

  • Correct Atwood LPCO 36636 Wires to Connect to RV Propane Gas and Carbon Monoxide Detector
    Hey Dan! Yes, you'll connect the red to red and black to black for installing the RV Propane Gas and Carbon Monoxide Detector # RS54FR in your situation. That extra red wire should be for a backup power source so the detector can still function if something happens to the first source.

  • Need Carbon Monoxide Detector To Replace Model 900-0140-LPM
    Hello Brad, thanks for reaching out. We do have a carbon monoxide detector that can be used to replace your old unit. Here is what I recommend: - RV Propane Gas and Carbon Monoxide Detector - 12 Volt - 2 Wire - Black # RS54FR This detector is for CO2 and propane so it does need to be mounted between 4" and 18" off the floor. It comes with a small and large bracket which cover most applications. It is also available in white as part # RS34FR if you prefer that. It has a 5-year lifespan...

  • Replacement For Atwood 36720 Propane Gas Detector
    For a replacement you could use the RV Propane Gas Detector # RS64FR (white) or # RS44FR (black). These are made in the USA with imported parts. If you want the version that also detects CO we have the # RS34FR or # RS54FR as well.

  • Replacement Recommendation for a Costar Model 12RV-D Monitor
    Hey Craig, thanks for reaching out! I recommend using either the RV Safe Gas and Carbon Monoxide Detector which comes in Black # RS54FR as well as White # RS34FR. These only install with two wires (red for power and black for ground) so whatever function your third wire carries won't be needed.

  • What Propane Gas will Replace My CCI Controls Model No. 7719 LP Gas Leak Detector?
    Hello Greg, The CCI Controls model number 7719 LP gas leak detector is an older model and it is recommended to replace it due to its age and potential for sensor failure. For a Propane gas detector replacement, I would go with the RV Propane Gas Detector - 12 Volt - 2 Wire - Black # RS44FR, or for white # RS64FR. If you needed one with a carbon monoxide detector as well, # RS54FR, or for white # RS34FR. These are the best options that we have for a replacement. It is an easy 2 wire...

  • Replacement and How to Remove a 900-0143-LPM Co2 Detector
    Hey Jeff, thanks for the picture. There's a locking tab on the top of the mounting plate behind your 900-0143-LPM detector. If you push it down you can slide the detector up and then you'll need to remove the two mounting screws to get the entire assembly off the wall. To replace it, I recommend the RV Propane Gas and Carbon Monoxide Detector item # RS34FR in white or item # RS54FR in black. It measures 4-1/4" long x 2-5/8" wide x 1/2" thick so it won't stick out nearly as much. It comes...

  • Is There Downside to Replacing RV Propane Detector with Propane/Carbon Monoxide Detector
    Hey Carlos, there's no reason you couldn't go with a propane and carbon monoxide detector like the part # RS54FR to replace just your propane detector. There's really no downside to having a way to monitor if there's a carbon monoxide leak as well.

  • Does the RV Safe Propane Alarm RS64FR Use the Same Wiring as a Safe-t-alert RV Propane Gas Detector?
    Yes, it is Sharon. The RV Propane Gas Detector item # RS64FR also uses a 12v DC power source and has an identical 2-wire setup. It's also available in black item # RS54FR. How old is your current Safe-t-alert RV Propane Gas Detector? You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.

  • What Carbon Monoxide Sensor do You Have to Replace My Costar 12RV-DB C0 Sensor?
    Hello John, Our carbon monoxide detectors also have the propane tester and they are installed near the floor since propane gas is heavier. Even though your propane tester sensor is green, they do have any expiration date on them (I attached an image showing that there is a date) so I recommend checking that as well. The RV Propane Gas and Carbon Monoxide Detector - 12 Volt - 2 Wire - Black # RS54FR is just a 2 wire system. All you would need to do to install is connect the Keystones...

  • Recommeneded Replacement Converter Charger and Carbon Monoxide Detector for a Forest River R Pod
    It looks like you're looking for a replacement converter charger for your WFCO-8955 55, in which you can use the Progressive Dynamics 9300 Series RV Converter Charger # PD79RR for lithium or # PD9260C for lead acid batteries. If you're wanting to just replace the entire power center, then I'd recommend using the Progressive Dynamics 4000 Series RV Converter w/ Charge Wizard and AC/DC Distribution Panel # PD4060K.

  • LP Gas And Carbon Monoxide Detector For An Atwood LP DOB 31013 LP Gas Detector
    Since the Atwood LP DOB 31013 is no longer available, your best option is to do a full replacement. I recommend going with the: -RV Propane Gas and Carbon Monoxide Detector # RS34FR for white, or the: -RV Propane Gas and Carbon Monoxide Detector # RS54FR for black. Both of these carbon monoxide detectors are flush mounted, measure 4-1/4" long, 2-5/8" wide, and 1/2" thick, and when either gas is detected a LED light and a loud horn will sound.
