The natural gas detector is used to detect combustible gas. When trigger the detector, it will alarm with build-in siren Power supply from AC 90V-240V or 9V rechargeable battery Auto detect sensor failure Avoid placement in close proximity to where airborne contaminants like cooking oils can coat and decrease sensor sensitivity. To avoid installing the detector close to the following sources of interference:Direct air flow from vents,fans,doors,windows,sources of steam,oil vapor etc.NOT approach the exhaust of gas vehicles for testing!. The battery and charging device can be used at the same time. Chooseing the suitable position to install the Detector according to the gas specific gravity.Detecting the gas heavier thanair: Installation height from floor 12-40 in,semi-diameter to gas source<60 in. Detecting the gas lighter than air,Installation height from the celling 12-40 in,semi-diameter to gas source<60 in.
