The floorboard of emergency lighting lamps. The fire emergency lighting system mainly includes accident emergency lighting, emergency exit signs and indicator lights, which are set to guide the trapped people to evacuate or launch fire fighting and rescue operations when the power supply in normal lighting is cut off.

However, in the daily inspection, it is found that there are many problems in the selection, installation and use of fire emergency lights. Therefore, the reasonable selection of power supply control mode and wiring mode and daily maintenance of emergency lighting system will directly affect the function of fire emergency lighting system.

Extended data:

Precautions:

1. Accurately grasp the characteristics of various wiring modes, avoid blind wiring, and fail to play its due role.

2. If emergency lighting is a part of normal lighting, three-wire controllable connection mode should be adopted.

3. For multi-storey public buildings, if there is no fire control center, the emergency lighting lamps in all parts can be controlled centrally by installing local switches (single-lamp single control or multi-lamp control) or connecting three wires in the distribution box.

4. For the project with fire control center, the fire control center should be able to turn on the fire emergency lighting requirements on the fire floor and related floors.
