From the safety point of view, the grounding wire (connected to the fire emergency fluorescent lamp shell) should be connected according to the requirements of the specification.
Usually, the red line is connected to the long bright line, the black line is connected to the switch live line, and the blue line is connected to the zero line. The installation is the same as the ordinary downlight, except that an emergency power supply is added to the ceiling.
Wiring: the switch wire is connected to the lamp holder, and the Changming wire is connected to the emergency power cord.

Installation and maintenance
1. In the engineering design, in order to facilitate the usual maintenance and management, it is best for the fire emergency lighting to be supplied by a special feeder circuit layer by layer.
2. In order to ensure the reliability of fire emergency lighting power supply, the power supply should be provided by the low-voltage emergency bus section of the substation, that is, when the diesel generator set is used as emergency power supply, as long as the generator is put into use, there will be electricity to continue to ensure power supply.
3. In the state of fire, there is less smoke and more oxygen near the ground, and the instinctive reaction of evacuation is to bend over or crawl forward, so local high-intensity lighting is more effective than uniform lighting brought by high-rise installation. Therefore, low-rise installation should be advocated, that is, evacuation emergency lighting should be set up near the ground or at the height of the ground.
All emergency lights are discharged from the factory and must be charged for 20 hours before use.
5. The performance of emergency lights in use should be checked regularly, and the circuit conversion and emergency function of the battery should be checked by continuous switch test every half month or one month, and discharged to prolong the service life of the battery.
6, completes the fire protection of distribution lines, dark apply laying in incombustible structure, the protective layer thickness is not less than 30mm；; Wear metal pipes when exposed, and brush fire retardant coatings or take other fire prevention measures outside the steel pipes; The line adopts fire-resistant cables or fire-resistant cables and wires.
