Product Description
This AC powered gas and carbon monoxide detector is designed for both single-station use and for connection to fire alarm or security alarm panels. Using a high-quality, durable sensor and MCU-based self-diagnostic technology, it continuously monitors for leaks of natural gas (methane), LPG/LNG, town gas, coal gas and carbon monoxide. When the gas concentration reaches the preset threshold, the unit activates a loud 80 dB alarm and red LED indicator to warn occupants at an early stage.
Compact in size and finished in ceiling white, the detector is suitable for wall mounting in homes, small commercial properties and recreational vehicles. It supports AC110V or AC220V input with low power consumption and includes optional relay output (NO/NC/COM) and DC12V pulse or steady voltage output, making it easy to interface with exhaust fans, gas shut-off valves or external alarm panels. With wide operating temperature and humidity ranges, quick warm-up time and clear status LEDs for power, fault and alarm, this gas/CO detector is an ideal choice for kitchen safety and small project integration.
