PNI GD-01 gas sensor, with audible and light warning, for LPG, natural gas, coal gas compatible with PNI V-02 solenoid valve

Semiconductor gas sensor

The PNI GD-01 gas detector is used to detect natural gas (methane), LPG gas (main components: propane, butane) and coal gas .

When the combustible gas leakage exceeds the standard (20％LEL), the gas detector will emit a continuous 70dB audible alarm accompanied by the red LED flashing.

The embedded semiconductor sensor has a long lifespan (up to 5 years), versatility and high tolerance to extreme ambient conditions and corrosive environments.

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

Sound and light alarm

When the gas concentration reaches the preset level, the device emits a visual and audible alarm. The red LED will flash rapidly accompanied by a continuous sound. If the detector is connected to the solenoid valve, it will send an electrical impulse to it. The solenoid valve will close the gas flow.

The alarm sound of at least 70dB reduces the risk of explosion and protects the life and safety of your property and family.

To stop the audible alarm, unplug the detector or wait until the gas concentration that triggered the alarm has decreased. After removing the cause that triggered the alarm, you can reopen the gas flow by lifting the red button on the solenoid valve (solenoid valve not included).

Never ignore an alarm!

Test method

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

Note: The sensor warm-up time is approximately 2-3 minutes. During this period, the gas test will not work . At the end of the warm-up (priming) period, the detector will emit a confirmation sound. After this time, 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, natural gas will rise to the ceiling and collect in the areas surrounding 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 sink 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 may trigger false alarms.
