The S5-CGD-20D Conventional Methane Gas Detector is designed to continuously monitor methane (CH₄) levels in residential, commercial, and industrial environments and detect potentially hazardous concentrations. Operating from a 12–24 V DC power supply, the detector monitors increases in methane concentration and provides early warning of possible gas leaks.

When alarm conditions are detected, the device provides audible and visual warnings. LED status indicators and a test button make it easier to check the operating condition of the detector, while the relay output allows connection to auxiliary equipment or compatible conventional fire alarm systems where required.

The S5-CGD-20D is suitable for indoor applications where methane gas may be generated or accumulate. Its compact design and low-voltage DC operation allow easy integration into different applications. The product is designed in accordance with EN 50194-1.
