Key Features

■ Complies with the national standard GB14287.4-2011 "Part 4: Faulty Arc Detectors of Electrical Fire Monitoring Systems" requirements

Connects with master stations, local branch exchanges, sensors, etc., for flexible construction of a high-capacity arc fault monitoring system

The system operates in an open mode, self-managed within, and transmits information unidirectionally externally.

■ Utilizes distributed power supply, with the detector powered independently, ensuring the system's stability and safety effectively.

The output loop can be flexibly expanded through local branch exchanges, adapting to the complex and variable requirements of modern buildings.

Real-time monitoring of all tested circuit currents, voltages, arc states, and fault information, and transmitting working status and alarm messages to the display device.
