I thought carbon monoxide detectors should be installed close to the ground?

Molecular weight of air (the mixture of gasses) is 29 g/mol, and molecular weight of CO is 28 g/mol. Air is mostly nitrogen, N2, and its molecular weight is 28 g/mol. In a still room, CO would have a slight tendency to rise. In an average house with some activity, CO would be evenly dispersed. Bottom line is that you could put the detector at any height and it should be okay, but higher would be marginally better. Contrast this with carbon dioxide, CO2, which has a molecular weight of 44 g/mol. This is significantly heavier than air. When I ferment my homebrew in a chest freezer, the generated CO2 doesn't come out quickly when I open the top. I can lower a flame into it, and it will extinguish when it hits the CO2 level. Try it, it's fun! M.Hall, Ph.D.

I'm not a "science" guy - just a homeowner who's had CO detectors for years. Mine are up high just where a smoke detector would be. Many friends and "experts" have seen them up there in my house. Nobody ever said it was not the correct location.

The instructions say to mount them on the center of ceilings or on interior walls, lower than 4" from the ceiling. They should not be within 3 feet of a bathroom.

I would make sure the wires are not touching some where , as this could be draining the battery.

Mine was installed about a foot below the ceiling on the wall, and it alerted me to a CO issue perfectly.

It would need to be close to a window for ventilation. Its suggested to be no more then 4 feet away from the vent source.

If you want to do that, just add wiring under the ground to delineate where you want the system working

http://osfm.fire.ca.gov/strucfireengineer/pdf/bml/Frequently%20asked%20questions%20on%20Carbon%20Monoxide.pdf"At what height/location should a CO device be mounted?According to the National Fire Protection Association (NFPA) 720, the location for effective performance is not generally dependent on mounting height. The density of carbon monoxide is similar to that of air at room temperature, and carbon monoxide generally mixes readily with air. The manufacturer's installation instruction should alsobe followed.

You want to place it where you can hear the alarm, even the bedroom, as if a leak happens at night you can hear it.It must be low to the floor as propane is heaver than air. The sensor will sound the alarm at a lot lower concentration than it takes for dangerous level to happen.Also keep it away from drafts- windows, heat resisters, etc.

You posed an interesting question so I thought I would do some research on the internet. According to the user documentation for this model (the documentation can be found under the "Download" tab on the http://www.firstalert.com/component/flexicontent/45-battery/288-battery-operated-carbon-monoxide-alarm web page), the CO detector can be installed "In Mobile Homes: Install CO Alarms on inside walls ONLY. Uninsulated outside walls and roofs of mobile homes often transfer heat and cold from outdoors. The Alarm should be located at least 6 inches (152 mm) from all exterior walls and at least 12 inches (305 mm) from supply or return vents." (I realize a mobile home is not an RV but the above information should be useful in determining if there is a place available given the above requirements.) The document also lists where co alarms should not be installed: "DO NOT LOCATE THIS CO ALARM: * In garages, kitchens, furnace rooms, or in any extremely dusty, dirty or greasy areas. * Closer than 20 feet (6 meters) from a furnace or other fuel burning heat source, or fuel burning appliances like a water heater. * Within 5 feet (1.5 meters) of any cooking appliance. * In extremely humid areas. This alarm should be at least 10 feet (3 meters) from a bath or shower, sauna, humidifier, vaporizer, dishwasher, laundry room, utility room or other source of high humidity. * In areas where temperature is colder than 40 F (4.4 C) or hotter than 100 F (37.8 C). These areas include unconditioned crawl spaces, unfinished attics, uninsulated or poorly insulated ceilings, porches, and garages. * In turbulent air, like near ceiling fans, heat vents, air conditioners, fresh air returns, or open windows. Blowing air may prevent CO from reaching the sensors. * Outside the Mobile Home. * In direct sunlight." I hope this helps.

I have the sensor nailed to a tree about three feet off the ground. It is very sensitive. I think installed at an angle above the garage would work. The receiver in the house works very well and beeps three times everytime something passes the sensor, could be a car, animal, or garbage man. Do not put the receiver near metal like a microwave it seems to block the radio waves. Also when the transmitter is rained on sometimes you get false readings. I put a plastic shroud over the top made from a yogurt container. Overall I am very pleased with the product and for the price it is a very good value. I highly recommend this product.

No it is not, whatever room you have it in make sure to have a carbon monoxide detector in it.

There are holes in the back for a screw or nail. It is very light weight. The sensors are two dime sized metal pads on the base so you can just set it on the surface you want to protect. Unhook the base plate (like a battery cover) and you can put the sensors about 6' feet away on a wire that plays out. If you do this you might want to mount it since the base is now partly removed.

The pamphlet inside the package recommends putting the detector in certain areas of the house that may become susceptible early-on such as stairs, near kitchen, etc. The height on wall is not specified. I have mine plugged in close to the floor. I am assuming it is calibrated to pickup on low CO levels before it becomes dangerous. You might have to call in and talk to their customer service people about the specifics.

I put them on the bottom side of gas tank and bottom side of frame. I used 3m double sided tape to help secure. We wired a separate switch to operate.

At ta minimum: Over the door on the inside of the bedrooms. In the living room, kitchen, and dining room. It is preferable to install CO detectors that plug into the outlet at the floor level in each room...but that can be quite expensive[But then how much is a life or lives worth?]

If there is metal below the surface of the ground it will signal the presence of it. So if you can bring it closer to the ground it should work up to four inches above the ground.

The antenna needs to be placed high next to a window. Make sure that all connections are snuggly tight.

No, the wires run out from the bottom and I believe being under ground would damage them.
