DHB-CW-J7620 Temperature Measuring Electrical Fire Monitoring Detector Parameters
Product Name: DHB-CW-J7620 Temperature Measuring Electrical Fire Monitoring Detector
Product 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.
