The construction of the system should follow the requirements of the design documents to prepare a construction plan. The construction site should have necessary construction technical standards, a sound construction quality management system, and an engineering quality inspection system. The construction unit should organize the supervision unit to inspect and fill in relevant records according to the provisions of Appendix B of GB51309.

The communication circuit adopts CAN bus communication technology, and the bus topology structure connects the emergency controller with the distribution devices in each area. The lighting supply circuit adopts two bus communication technology, and the bus topology and free topology connect the distribution devices with the emergency lighting circuit.

Each centralized control emergency lighting fixture in the circuit has an independent ID, which can independently execute instructions and actively report the status information of the lighting fixture. The built-in microcontroller of the lighting fixture can detect the light source situation in real-time.

When there is main power:

The centralized power supply for emergency lighting, AC220V input and output, supplies power to the regional emergency lighting distribution device and also supplies power to the battery

2. When there is no main power:

The battery supplies power to emergency evacuation lighting fixtures through a regional router;
