ATL-920 Intelligent fixed temperature heat detector

ATL-920 Intelligent fixed temperature heat detector

DC 24V; standby current≤300μA alarm current consumption≤1.5mA; External dimension: Φ100x47mm;

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.
