ATL-930 Intelligent photo-electric smoke detector

Product features  It can realize electronic coding and rewrite the address via coder in situ.  Within a single-chip microcomputer, it can process the sampling data in real-time, save the latest 144 historical data and realize a curve tracing for the field situation.  It has a temperature, humidity and dust accumulation drift compensation function and a sensor fault detection function (fault reporting to fire alarm control panel).  Non-polarity, two-bus connection that ensures convenient installation and maintenance.  Designed with an upper cover and a lower cover and installed on an independent base, it can be installed, debugged and maintained conveniently.
