The GLA-222-B LPG Gas Leak Detector is a wall-mounted household gas alarm designed to swiftly and reliably detect the concentration of combustible gases or vapors. Using advanced semiconductor technology, this detector ensures a fast response to the smallest gas leaks, providing both visual and audible alarms when the gas concentration surpasses pre-set levels. With integrated LED indicators and a buzzer, it alerts users promptly, allowing for immediate action. This gas leak detector is optimized for efficiency, featuring a diffusion-based gas sampling method and a response time of less than 5 seconds in case of excess leaks, with automatic resumption. The device operates on 24VDC or 230VAC power supply, offering a convenient plug-in design for easy home installation. An optional single alarm relay is available for shutting off the gas valve in case of an emergency.
