Pack 2 pcs PNI Safe House 400 Kit Gas Sensor & Solenoid Valve 3/4 Inch, Audible & Light Alarm, 85dB, Detects Natural Gas, Methane Gas (CH4)

Modern gas sensor

The gas detector in the PNI Safe House 400 kit is used for the detection of natural gas (methane), LPG gases (main components: propane, butane) and coal gases.

When the combustible gas leak exceeds the standard (10%LEL), the gas detector will emit a continuous 85dB audible alarm accompanied by the flashing red LED.

The built-in semiconductor sensor has a long service life (up to 5 years), versatility and high tolerance to extreme environmental conditions and corrosive environments.

Note: The sensor cannot detect toxic gases such as carbon monoxide (CO).

Safety and energy saving

The plug-and-play connection mode makes the PNI Safe House 400 kit extremely easy and practical to install. Flame retardant ABS plastic is anti-mildew, anti-pest, anti-corrosion, and is easy to clean.

With a minimum power consumption of less than 3W and a low price, the PNI Safe House 400 kit helps ensure the safety of your home. The kit can be widely used in restaurants, kitchens, hospitals, hotels, oil factories, garages, gas stations, and so on.

Test method

While holding down the lighter button, bring the lighter closer to the gas inlet of the detector and release the gas slowly (do not light the lighter, just let gas out). When the gas concentration around the sensor reaches the standard, it will trigger the alarm that will sound until the volume of gas in the medium drops below the alarm point.

Note: The heating time of the sensor is about 2-3 minutes. During this period, the gas test will not work. At the end of the heating (priming) period, the detector will emit a confirmation sound. After this moment, the detector enters the normal operating state.

Installation

Natural gas is made up of methane gas, which is lighter than air. In the event of a leak, the natural gas will rise towards the ceiling and collect in the surrounding areas of the ceiling. Therefore, for natural gas, the detector will be installed 30 cm below the ceiling and 1.5 m away from the gas source.

LPG gas consists of a mixture of propane and butane, which is heavier than air. If LPG leaks, it will descend to the ground. Therefore, for LPG, the detector should be installed 30 cm above the floor and 1.5 m away from the gas source.

Note: Do not install the gas detector in a place with a lot of water vapor, as this may affect the sensor which can trigger false alarms.
