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

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 sound alarm accompanied by red LED on.

The built-in semiconductor sensor has a long life (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 frequently accompanied by a continuous beep. If the detector is connected to the solenoid valve, it will send an electrical pulse to it. The solenoid valve will shut off 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 concentration of the gas 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 closer to the gas inlet of the detector and release gas slowly (do not light the lighter, just let gas escape). 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 moment, the detector enters the normal operating state.

Installation

Natural gas consists 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 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 go down to the ground. Therefore, for LPG, the detector must 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 can damage the sensor which can trigger false alarms.
