ST420HF Series Combined Electrical Fire Monitoring Detector
ST420F products through the double test, can be widely used in thousands of industrial, commercial
Device Introduction
The ST series electrical fire monitoring equipment and ST series electrical fire monitoring detectors developed by our company are based on relevant national standards.
690Vthe following TT, TN system design, to meet all kinds of electrical fire monitoring system requirements.
STseries electrical fire monitoring equipment communicates with various ST series electrical fire monitoring detectors on site, receives and forwards its data, realizes fault alarm, and records and stores faultsinformation; ST series electrical fire monitoring detectors monitor and manage the residual current and temperature electrical fire hazard parameters of the distribution circuit to prevent the occurrence of electrical fires.industrial enterprises.
device is suitable for the centralized monitoring and management of electrical fire prevention in places where electrical fire can occur, such as large shopping malls, living quarters, industrial and mining enterprises, office buildings, shopping malls and hotels.

Device Features
※The electrical fire monitoring equipment is connected with the electrical fire monitoring detector through RS485 bus to form an electrical fire monitoring system;
※Electrical fire monitoring equipment can receive and process the residual current and temperature signals sent by various detectors in real time, and display them on the LCD screen at the same time;
※When the residual current, over-temperature alarm and power supply, communication failure, the monitoring equipment can send out sound and light alarm signal, displayed on the screen;
※Electrical fire monitoring equipment has the functions of data storage, query and alarm control signal output;
※Electric fire monitoring equipment shall be powered by dual power supply, and the main and standby shall be switched automatically; the working status of the main and standby power supplies shall be indicated by LED on the panel;
※The electrical fire monitoring equipment has a self-check function. After the monitoring equipment is started, first perform a self-check on the machine, and then enter the main interface;
※Electrical fire monitoring equipment provided8relay output, used to control the protected circuit or other equipment;
※the residual current protection and temperature protection of the distribution circuit by the electrical fire monitoring detector.
