The JT-AT2004A / JY-AT2004A Series is an intelligent household combustible gas detector providing all-round family safety protection. Equipped with advanced temperature compensation, it adjusts detection parameters according to ambient temperature changes, avoiding false/missed alarms for natural gas and LPG. It has an automatic lifetime expiration reminder to prompt timely replacement. Supporting wireless solenoid valve connection, it cuts off gas sources quickly when leakage occurs, with clear valve status indication. A built-in black box records alarms, faults, and logs for maintenance. Unique in supporting NB-IoT/4G CAT1, it enables remote gas status monitoring via mobile devices. Made of V0-rated flame-retardant material with IP31 protection, it resists dust and light water splashes. Compact, lightweight, and easy to install, it is an essential intelligent safety helper for modern households.
