Installation and maintenance of emergency lights
1. In the engineering design, in order to facilitate the maintenance and management at ordinary times, the fire emergency lighting should preferably be powered by a dedicated feeder circuit by floor.
2. In order to ensure the reliability of the power supply for fire emergency lighting, the power supply should be supplied by the low-voltage emergency bus section of the substation, that is, when the diesel generator set is used as the emergency power supply, as long as the generator is put into use, it will have electricity to continue to ensure powered by.
3. In a fire state, there is less smoke and more oxygen near the ground, and the instinctive response of people to evacuate is to bend over or crawl forward, so local high-intensity lighting is higher than high-level lighting.
The uniform illumination brought by the installation is more effective. Therefore, low-level installation should be promoted, that is, emergency lighting for evacuation should be provided close to the ground or at ground level.
4. The emergency lights are all discharged from the factory and must be charged for 20 hours before use.
5. The performance of emergency lamps in use should be checked regularly, and the continuous switch test should be passed every half month or one month to check the circuit conversion and the emergency function of the battery, and discharge it to prolong the service life of the battery.
6. Do a good job of fire protection for power distribution lines, lay them in the non-combustion body structure when laying in the dark, and the thickness of the protective layer is not less than 30mm; wear metal pipes when laying openly, and brush fire-retardant paint on the outside of the steel pipes or take other fire-proof measures; Use fire-resistant cables or fire-resistant cables and wires.
