    How to use:

    Gas Leakage Detector

    • Please confirm the induced gas is heavier or lighter than air. Heavier gas than air such as LPG etc. Lighter gas than air such as natural gas, marsh gas etc
    • Choosing the proper position to install the Detector according to the gas specific gravity. Detecting gas is heavier than air: Installation height from floor: 0.3-1.0m, Semi-diameter to gas source: <1.5m;Detecting gas is lighter than air: Installation height from ceiling: 0.3-1.0m, Semi-diameter to gas source: <1.5m
    • Fix the screw into the wall firmly, then hang the detector
    • Avoid installing the detector too close to the following sources of interference: direct air flow from vents, fans, doors, windows, sources of steam, oil vapor, etc
    • All wires installation must accord with the National and Local effective laws and criteria. The wires must have suitable size and colorful marks to avoid connecting error. And unseemly connection of wires will result in the alarm error while gas leaking happened

    Smoke Detector:

    • A smoke detector is a device that detects smoke, typically as an indicator of fire. Commercial, industrial, and mass residential devices issue a signal to a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible and/or visual alarm from the detector itself
    • Smoke detectors are typically housed in a disk-shaped plastic enclosure about 150 millimetres (6 in) in diameter and 25 millimetres (1 in) thick, but the shape can vary by manufacturer or product line. Most smoke detectors work either by optical detection (photoelectric) or by physical process (ionization), while others use both detection methods to increase sensitivity to smoke. Sensitive alarms can be used to detect, and thus deter, smoking in areas where it is banned such as toilets and schools. Smoke detectors in large commercial, industrial, and residential buildings are usually powered by a central fire alarm system, which is powered by the building power with a battery backup. However, in many single family detached and smaller multiple family housings, a smoke alarm is often powered only by a single disposable battery

    Carbon monoxide and carbon dioxide detection:

    • Some smoke alarms use a carbon dioxide sensor or carbon monoxide sensor in order to detect extremely dangerous products of combustion. However, not all smoke detectors that are advertised with such gas sensors are actually able to warn of poisonous levels of those gases in the absence of a fire
    • Performance differences
    • Optical or "toast-proof" smoke detectors are generally quicker in detecting particulate (smoke) generated by smoldering (cool, smokey) fires. Ionization smoke detectors are generally quicker in detecting particulate (smoke) generated by flaming (hot) fires
    • According to fire tests conformant to EN 54, normally the CO2 cloud from smoke can be detected before particulate
    • Obscuration is a unit of measurement that has become the standard definition of smoke detector sensitivity. Obscuration is the effect that smoke has on reducing visibility. Higher concentrations of smoke result in higher obscuration levels, lowering visibility

    Package Included:

    • 1 x High Security Wireless Gas Leakage Detector

good buy

Seems to work ok. No false alarms. I assume it's working but I haven't tested it with the gas stove, etc. I installed it on upper wall for natural gas detection as per instructions. The extension electrical wire plug is handy. I think its a good buy.

Wonderful product
00:00:00 04-12-2011
Our old LP gas detector quit working and we were looking for one that we could just plug into a 110 volt outlet in our RV so that we wouldn't have to cut holes in the wall, hire an electrician to hard wire it in, etc. And this one fit the bill precisely! All we had to do was to unpack it and plug it in to an outlet that was close to the floor. It does stick out 2-3 inches from the wall, but it has never become unplugged accidentally.

It's cool
00:00:00 03-30-2011
Haven't had a scare yet, so I'm guessing since it's on, it gets the job done. I just wish there's a better way to power it (using a battery so that you don't have to hide an ugly cord).

Gas CO detector
00:00:00 03-22-2011
Excellent unit and I have purchases 4 over the past year. <br/>I put one near every gas appliance in the house including a gas furnace & hot water tank, gas stove, gas fireplace and a gas space heated in the reck room. Better safe than sorry ! <br/>Best price I could find anywhere, plus fast delivery, and free shipping no tax.

No false alarms, drains battery
00:00:00 03-07-2011
I guess the detector is working. I've had no false alarms or readings on the screen. As others have said, I don't think one unit with a dual purpose is a good idea. I have this unit placed directly beside my gas furnace and water heater. Then I have a dedicated CO detector in the bedroom. <br/> <br/>And as someone else said, the unit drains the battery while it is plugged in. Why? Who knows, but the battery must be replaced every few months.

Works so far!
00:00:00 02-17-2011
I havent had it go off. I assume that I dont have a leak anywhere. I use it for LP and you have to mount it close to the floor. THe design is top notch. I really like how they put the power cord in the back so if you just need to plug it into a outlet you leave it in, but if you need to mount it high you pull the cord out. Display is easy to read and if it would happen to come unplugged there is a battery backup as well. Also if it does come unplugged it beeps to let you know.
