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.
