Smoke & Gas Detector with Digital Display, Combustible Gas Alarm

The wall-mounted smoke gas detector is designed for reliable detection of gas leaks. Advanced semiconductor sensor is adopted to ensure high stability and long life. The smoke alarm is suitable for the safety of residential house, villas, hotels, markets, boarding house etc.

Features

• The smoke gas detector utilizes a high-reliability sensor to ensure accurate and dependable gas leak detection.
• It automatically resets after an alarm to provide continuous monitoring without manual intervention.
• MCU processing technology is adopted for enhanced performance and control.
• The detector includes an auto-detection feature for sensor failure to maintain operational integrity.
• It is designed to detect both natural gas and LPG (liquefied petroleum gas) for versatile safety applications.
• The gas alarm features SMT (Surface Mount Technology) design for improved stability and reliability.

Tips: Precautions for installation of smoke and gas detector

• Installation location: Wall-mounted within 1 meter from the ceiling, no more than 4 meters in height, and no more than 4 meters away from the gas.
• Installation height: Since the POM of the gas is lighter than air, it will rise when the gas leaks. Therefore, when installing the detector, it is generally installed in a higher place, but not too far from the gas source, within 2-4 meters is appropriate, and the radius is about 1.5 meters from the gas source.
• Installation environment: When installing at home, it should be noted that the installation location should not be too close to the gas stove to prevent the detector from being baked by the stove flame, thereby affecting the detector's sensitivity.
