1, in the engineering design, in order to facilitate the normal maintenance and management, fire emergency lighting is best based on the layer to the special feeder circuit power supply.
2, in order to ensure the reliability of fire emergency lighting power supply, conditional should be the substation of the low-voltage emergency bus section power supply, that is, when using diesel generator set to do emergency power supply, as long as the generator put into use, it will have electricity to continue to ensure power supply. 3, in the fire state, near the ground less smoke, more oxygen, the instinctive response of people evacuated is bent or creeping forward, so the local high illumination illumination is more effective than the uniform illumination brought by the high installation.
Therefore, low installation should be promoted, that is, to provide evacuation emergency lighting close to the ground or at ground height.
4, emergency lights are discharged in the state of the factory, before use must be 20 hours of charging, in order to discharge.
5, the use of emergency lamps should be regularly checked for performance, every half or one months through continuous switch test, to check the circuit conversion and battery emergency function, and discharge, in order to extend the battery life.
6, do a good job of power distribution line fire protection, when the dark compress in the non-burner structure, the thickness of the protective layer is not less than 30mm, when the metal pipe is worn, and in the outside of the steel pipe to brush fireproof paint or the use of other fire prevention measures; the line uses fireproof cable or refractory cable, wire.
