Addressable heat detector BP-FD-AHD302

It can realize electronic coding and rewrite the address via coder in situ.
Within a single-chip microcomputer, it can realize real-time data acquisition and processing, realize a curve tracing for the field situation.
It has a temperature 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.
Built-in remote indicator output terminal, drive remote indicator lit when fire alarm
