DHB-CW-J7620 temperature measuring electrical fire monitoring detector

Features

The temperature-measuring electrical fire
monitoring detector is a stand-alone intelligent detector. It has the function
of temperature probe fault diagnosis, high alarm accuracy, high reliability,
simple and practical, and convenient installation.

Scope of application

It is suitable for use in complex
facilities such as factories, large warehouses, offices, commercial buildings,
hotels, residential and entertainment venues where electrical fires are most
likely to occur.

working principle

The internal circuit of the temperature
detector consists of a single chip microcomputer, a data memory, a
human-machine dialogue circuit, a loop interface circuit, and a multi-machine
communication interface circuit. The man-machine dialogue circuit is mainly
composed of a key input circuit, a display drive circuit, an indicator display
circuit and a digital tube display circuit. Through these circuits, the fire
alarm threshold of the temperature probe can be set, the measured temperature
value is displayed, and the state of the temperature probe is indicated ( That
is, the fault state, the fire alarm state, and the normal working state), the
loop interface circuit can receive and process the signal transmitted by the
lower terminal temperature probe.
