With the terminal controller, regional extension, regional repeater, sensors, etc., flexible construction of large-capacity electrical fire monitoring system, the system adopts non-open operation mode, self-management within the system, external one-way transmission of information by centralized power supply, to provide DC24V safety voltage power supply to the field sensor, effectively ensure the stability and safety of the system;

The system can be flexibly expanded through the regional extension to adapt to the complex and changing requirements of modern buildings to monitor the line current value and temperature value information of all monitored fire control boxes in real time, and transmit the working status and alarm information to the graphic display device of the fire control room. The monitor can output 2 communication loops, the communication capacity is 2x512 =1024 sensor system adopts F-BUS fire two bus as the communication platform to ensure the reliable and stable operation of the system in various electromagnetic environments.
