System Features
Meets the requirements of National Standard GB14287.2-2011 "Electrical Fire Monitoring System"
Connectable with master stations, local branch exchanges, sensors, etc., flexibly build a large-capacity electrical fire monitoring system
The system operates in an open mode, self-managed internally, and transmits information unidirectionally externally.
The output loop can be flexibly expanded through local branch exchanges, accommodating the complex and variable requirements of modern buildings.
Monitor all remaining leakage currents and fault alarm information in real-time, and transmit the working status and alarm information to the host control system display unit.
