ATL-920 Intelligent fixed temperature heat detector

Product features
1 It can realize electronic coding and rewrite the address via coder in situ.
2 Within a single-chip microcomputer, it can realize real-time data acquisition and processing, realize a curve tracing for the field situation.
3 It has a temperature compensation function and a sensor fault detection function (fault reporting to fire alarm control panel).
4 Non-polarity, two-bus connection that ensures convenient installation and maintenance.
5 Designed with an upper cover and a lower cover and installed on an independent base, it can be installed, debugged and maintained conveniently.
