Description
The JT-AT2004BII is an energy-saving household bus-type combustible gas detector with a unique 2-wire design, integrating power supply and signal transmission without external 24V power, simplifying wiring and reducing installation costs. Advanced temperature compensation adjusts detection parameters to ambient temperature, ensuring accurate, stable detection of combustible gases and avoiding false/missed alarms. It has an automatic lifetime expiration reminder to prevent risks from expired equipment. A built-in black box records alarms, faults, and logs for quick troubleshooting. Made of V0-rated flame-retardant material with IP31 protection, it resists dust and light water splashes. As a bus-type detector, it has good expandability, connecting multiple units for centralized monitoring, suitable for larger households or multiple gas usage points.
