ARCM200-J4 fire detectors Product Overview electric fire alarm system (hereinafter referred to as the system) for on-line detection AC220 V/380 V distribution line residual current (ie, leakage current), when any one of the monitored circuit leakage current Over leakage at pipe value, the system that is audible and visual alarm signal, indicating the size of the leakage current, indicating leakage position. At present, the domestic electrical fire monitoring system are electronic products, used in low voltage distribution systems are vulnerable to other components in the distribution system or line electromagnetic interference. Electrical fires for the following reasons: (1) spark and arc; (2) electrical equipment or electrical lines to generate heat; (3) due to line terminals poor contact with the terminal wires produced dangerous temperatures. Distribution system to produce over-current and residual current (leakage current) often does not immediately result in a fire, but the line has been the long-term overload operation or a residual current distribution lines can cause fever, insulation aging and eventually cause a fire. ARCM200-J4 fire detectors can be set to protect the performance characteristics of multi-leakage protection, you can set the overcurrent protection, overvoltage, undervoltage, phase, ambient temperature, etc. Multifunction Protection; power management functions of the monitoring system to achieve the right supply line phase voltage, phase current, three-phase power, apparent power, useful power and other electrical parameter measurement; remote monitoring using a common standard modbus communication via RS485 reliable, the information will be transmitted to the master site points to decision-making control; tripping control with manual and automatic tripping function. Need to manually reset after tripping; Emergency Operations Control Panel can be directly fault tripping electricity transmission, and accompanied by an alarm buzzer; rich reality interface LED, LCD and many other good man-machine interface, do not let the operator will be able to read hands Learn all the information; audible alarm sound alarm states have different functions, while providing live recording function; overhaul maintenance tips can provide prompt warning; fault memory of the monitoring system can record in real time without missing any moment of failure, for the analysis of site to provide strong strong basis, you can scroll through the records more than 100 times the FIFO failures and power down to save; fire linkage can accept or provide external fire control;
