KLN-GDQ-15 Gas Leak Alarm Detector with Automatic Cutoff Valve Product Specifications: Model: KLN-GDQ-15 Detection Gas Type: Liquefied Petroleum Gas (LPG), Natural Gas Valve Body Material: Brass Alloy Sealing Material: NBR Maximum Pressure: 10kpa Connection Method: G1/2, G3/4, G1 Closing Method: Current Pulse or Manual Drive Voltage: DC9V-12V Closing Time: Less than 1 second The KONLEN Liquefied Petroleum Gas and Natural Gas Leak Alarm Detector with Electric Cutoff Solenoid Valve (Model KL-GDQ15) is designed to provide enhanced safety against gas leaks. Upon detecting a leak, the device emits a beep alarm sound and automatically triggers the solenoid valve to close the gas supply, effectively preventing potential fire accidents. Compatibility: Suitable for European (EU) and American power plugs. Not compatible with British and Australian (AU) plugs. Installation Instructions: Prepare the pressure relief valve and solenoid valve. Unscrew the nut on the solenoid valve. Screw the nut onto the pressure relief valve. Insert the pressure relief valve into the solenoid valve sealing ring as shown in the figure, and then tighten the nut. Connect the air pipe between the solenoid valve and the gas detector; connect the other end of the pressure relief valve to the household gas bottle to complete the installation. Installation Guidelines: The gas detector should be installed based on the weight of the gas relative to air. For gases lighter than air (e.g., natural gas and coal gas), install the detector within 0.3m to 1.2m from the ceiling and at least 1.5m in diameter from the gas source. For LPG, which is slightly heavier than air, install the detector 0.3 to 1.2 meters above the ground and within 1.5m in diameter from the gas source. Ensure proper installation for optimal performance and safety. Always follow local regulations and guidelines when installing gas detection and control systems.
