What To Know Before Buying RV Propane Detector

rv-propane-gas-detector

Since we’re talking about safety here, it’s only essential that you choose the best propane detector for your RV. These devices aren’t just for decoration, but they serve as your protection from harmful gas leaks. Before you shop around, here are essential things that you should be aware of.

The Different Types Of RV Gas Detectors

RV propane detectors can be available in two primary forms, portable and fixed. Portable detectors are usually battery operated RV propane detector models, while the fixed types need to be mounted close to the protected area. These detectors can also fall into different categories depending on their operation mechanism.

  • Electrochemical

Electrochemical detectors are commonly used to detect carbon monoxide and other toxic gases. These units are highly sensitive, and they use electrical currents to send off warning signals. Many of these models come with a digital display.

  • Semiconductors

Also termed as metal oxide semiconductors, these devices also detect carbon monoxide and other poisonous gases. These detectors work through a gas film that consists of tungsten or tin oxides. When exposed to a high temperature, the film generates free electrons to produce current.

Compared to electrochemical models, semiconductors seem to be more efficient as they work in low-humidity scopes. Many of these detectors are RV carbon monoxide & propane gas alarm models because they can detect combustibles aside from toxic gases.

  • Catalytic

Catalytic gas alarms are used to detect combustible gases, like propane and methane. These detectors usually use a platinum treated wire coil to detect these harmful gases. The higher the gas level entering the sensor room, the higher the gas detector reading.

For the catalytic detectors to work correctly, they need oxygen. The gas won’t undergo a reaction process when the oxygen reduces too low.

  • Infrared

In the absence of oxygen, infrared gas detectors are the best solution to measure combustible gases. These devices use the concept of light absorption to gauge the traces of combustible gases in the air. This detector type’s main benefit is its ability to not lose their sensitivity even after extended exposure.

  • Photoionization

For toxic gases and volatile organic compounds, like aromatics, photoionization detectors are a great choice. These units use high energy ultraviolet light to ionize the gas. This type is significant for detecting combustible gases that become a toxic hazard even when present at very low levels.

Benefits And Drawbacks Of RV Propane Detectors

Most RV appliances use propane to fuel energy. To make sure that there are no gas leaks from your propane appliances, getting a propane detector is a good idea. These devices are useful in detecting the existence of poisonous and combustible gases in your RV.

When you have a terrible sense of smell, getting a propane detector is specifically useful. These units will produce sound and light alarms to let you know that there’s gas leaks inside your RV. Even when you’re sleeping, the sound of the alarm won’t fail to wake you up for safety.

Either way, installing this device in the RV gives you peace of mind. You can shut off the propane source right away to stay you away from danger. Keep in mind that inhaling too much propane can suffocate your lungs and make it hard to breathe.

However, not all of these units can be accurate in giving readings. Some of them can be intermittent with their service. More importantly, you have to replace these units every 5-7 years to ensure maximum protection.

Things To Look For When Buying An RV Propane Detector

Getting the right propane detector is essential for the safety of the people inside the RV. Besides what I stated above, here are some essential things to consider when choosing the perfect propane detector.

  • Safety Certifications

To guarantee the optimum performance of gas alarms, look for safety certifications from reputable organizations. Most of the best gas detectors are UL certified. [Underwriter Laboratories of Canada (ULC) is one of the independent organizations that offer reliable inspections for product safety.

  • Multiple Gas Detection

As possible, look for a gas alarm that can detect multiple gases. A carbon monoxide detector is usually common, but if you add a propane detector, you add more safety to your RV. To reap the best of both worlds, search for an RV CO and propane detector. Most models of this list can detect natural gas and propane to add more functionality to the unit.

  • End Of Life

The lifespan of propane detectors is a bit limited. Most models can last from five to seven years. When buying an RV propane detector, look for the manufacturing date. Make sure that it’s dated this year and not the past year, or you’ll end with a model with a shorter life span.

  • Sound Alarm

The detector should trigger an alarm when it detects that the gas has reached a dangerous level. The alarm should be loud and clear that a heavy sleeper can wake up from it. It shouldn’t stop or reset unless you intend to do something.

The best detectors send an alarm that’s at least 80 decibels loud, which is equivalent to a power lawnmower or a noisy restaurant. Anything above 85 decibels can be harmful to your hearing, though. In some models, the sound alarm is accompanied by flashes of red light and even voice warnings.

  • Indicators Lights

For great ease of use, look for indicator lights to take out the guesswork of operation. Typically, detectors show a green indicator light to indicate that it’s working well. A red light means that the unit detects an unhealthy level of propane inside the RV.

An alarm to alert a fault condition is also important because it can make you aware that the unit is falsely showing a safe condition. The last thing you need is your detector showing a zero reading even when harmful gases are looming inside your RV.

An end of life notification is also useful for the best performance of detector units. You’ll know that the unit needs to be replaced when it blinks a yellow color. If you don’t heed the warning, then the detector will shut down and become ineffective.

  • Response Time

The propane detector should respond as quickly as possible. However, response time may vary depending on its sensor type, signal processing electronics, and sample transportation. Some models may be slow, while others can respond to the gas buildup faster.

The necessary response time will rely on the area, system’s purpose, and development of the expected issue. Large leaks need a quick response, whereas a slow buildup of gas concentration can suffice with a slower response.

If you want to know the response time of your propane detector, make a test. Try putting an unlit lighter near the device and see how fast it can respond.

  • Warranty

To have peace of mind, look for an extended warranty to cover all defects and malfunctions. Most models offer the basic 1-year warranty while others provide a year more. Other reliable manufacturers even go a step further by offering refunds for your satisfaction.

Troubleshooting And Maintenance

You must never open the device when combustible gas is present. Regularly wipe the detector with a damp cloth to remove any dust. When the sintered metal filter is contaminated with gas or solvent, replace the sensing head and increase the inspection frequency.

Calibrate the propane detector at least once yearly to appease any sensitivity loss. The calibration should be done according to the manufacturer’s given procedures. You can also hire qualified personnel to do the calibration for you.

When your unit shows a non-zero reading, it means that there’s gas detected in the area. You need to calibrate the device if it shows a non-zero reading even when no propane exists or reads too low or too high.

Check the electrical connections, sintered filter, and sensor when the unit shows a zero reading in the existence of gas. A fault signal might indicate that the electrical connection is wrong or the sensor got disconnected.

Furthermore, to keep your RV safe, don’t forget to check our RV propane regulator guide and read our review about propane tank gauge to find the best products.

Who Makes The Best Propane Detector For RV

MTI Industries seems to lead the pack in the propane detector industry. This manufacturer provides several good models of propane detectors, especially on their Safe T Alert series. In particular, the 30-442-P-WT impresses with its rapid recovery sensor and Mute button.

RecPro is another great contender with its extra-long lifespan. While most detectors offer a 5-year lifespan, RecPro adds two more years for more RV security. Best of all, its detector provides a 2-year warranty, which gives more peace of mind.

If you want more advanced technologies, GasKnight never disappoints. This brand includes voice warnings into the alarm system, so you’ll never miss it even when you sleep. The plug-in style makes it even more adorable as installation becomes hassle-free.

How Does An RV Propane Detector Work

RV propane detectors are powered with 12-volt DC and connect straight to the house batteries. Some models are linked t directly to the LP-gas tank’s electric solenoid valve in case of power failures. Others simply activate in the existence of propane gas.

These products detect gas using different sensors, such as electrochemical, semiconductor, and infrared. A propane detector will measure the gas concentration in a particular area through these sensors. If this device detects a high gas concentration, it will sound an alarm.

Why Does My RV Propane Detector Keep Going Off

Since detectors are susceptible to propane, your unit might detect it even when you didn’t smell it. For your safety, shut off any propane supply and leave the premises. See if the alarm stops after ventilating it for several minutes. When it stops, the unit is detecting toxic fumes.

Once you determine the propane leak’s exact source, get it checked and repaired by a trusted technician. In some cases, the detector can go off when you have low house batteries or needs to be replaced. Other things that can activate the alarm are chemical cleaners, dog farts, Febreeze, cooking fumes, and even hair sprays.

Where To Mount Propane Detector In RV

The type of gas may dictate where you should mount the propane detector. For gas lighter than air, like natural gas, mount the detector near to the ceiling. Consider mounting the detector close to the floor if you want to use the detector for heavier gases, like propane, butane, and LPG.

For the case of ammonia, you have to mount two detectors: one near the ceiling and another near the floor. This is because ammonia is lighter than air but gets heavier when it absorbs moisture from the atmosphere.

How Do You Replace A Safe T Alert RV Propane Gas Detector

First, turn off the power to the DC circuit, then remove the fuse to cut the power. Next, open the faceplate and cut the two wires linking to the detector. Strip the detector wires and connect them to the new alarm’s leads.

Rewire the new alarm using the same colors and consider using connectors to get a secure connection. Nylon crimp connectors seem to work perfectly with DC wiring. Once the rewiring is done, fix the new unit back into place and restore the fuse to turn the new unit’s power back on.

How To Set Up And Use

Set up your propane detector near propane appliances, such as heaters and stoves. Place them near the ceiling since propane is heavier than air. To set up, screw the bracket on the wall and hang the detector on the holes.

Hook the propane detector to the power supply. Test the new unit by pressing the test button. You might need to press the button a couple of times and endure the deafening noise before you achieve a solid green light to indicate that all is working well.

Conclusion

Propane detectors are truly a blessing if you want to feel safe throughout your RV outing. These devices detect harmful propane levels filling your RV to help you avoid possible accidents. If I have to pick the best RV propane detector, my choice would be the MTI Industries 30-442-P-WT because it seems to be the most efficient in detecting gas leaks.

If you like a longer lifespan, I recommend RecPro and Atwood 36719 because both offer seven years of service. HSTMYFS and EG propane detectors are outstanding when it comes to digital readings. For the best plug-in detector, I suggest GasKnight.
