1, In engineering design, in order to facilitate the usual maintenance and management, the best fire emergency lighting according to layer to feed the automatic emergency lighting circuit power supply.
2, In order to ensure the fire emergency lighting power supply reliable, conditional by the substation of the low-voltage emergency bus section power supply, that is, when using diesel generating sets as emergency power supply, as long as the generator put into use and the emergency light battery supply enough , It will have electricity to continue to ensure power supply.
3, In a fire state, less smoke near the ground, more oxygen, the evacuation of the instinctive reaction is bending over or prostrate forward, and thus local high-illumination than the high-level installation of uniform illumination is more effective. Low-level installations should therefore be promoted, ie emergency evacuation lighting should be provided near the ground or at ground level.
4, Emergency lights are discharged state factory, before use must be charged for 20 hours before discharge.
5, The use of emergency lighting should be regular performance checks, every half month or month through a continuous switch test to check the circuit switching and battery emergency functions and discharge to extend the life of emergency light battery.
6, Do a good job in the distribution line of fire protection, concealed when laid in the non-combustion body structure, the protective layer thickness of not less than 30mm; Ming Fu wear metal pipe, and outside the steel brush or use other fire retardant coating; Fire-resistant cable or fire-resistant cable, wire.
