Linsheng – Information About Fire Emergency Lighting
The fire emergency light has the advantages of reliable operation, high stability, long service life, etc. It is suitable for high-rise buildings such as factories, hotels, shopping malls, buildings, etc., for public use for power failure for emergency lighting, metal lamp head or flame-retardant plastic lamp head, with wall-mounted , portable, hanging installation. The emergency time is ≥90min, the principle can refer to the principle of electromagnetic relay, which is similar.

The fire emergency lighting system mainly includes accident emergency lighting, emergency exit signs and indicator lights, which are set up after the normal lighting power supply is cut off in the event of a fire, guiding the trapped personnel to evacuate or launch fire fighting and rescue operations. However, in daily inspections, there are many problems in the selection, installation and use of fire emergency lighting fixtures. In response to this, reasonable selection of the power supply control mode and wiring mode of the emergency lighting system and daily maintenance work directly affect the function of the fire emergency lighting system.

linsheng pointed out that compared with the power supply independent control type emergency lighting, the centralized power centralized control emergency light has the advantages of convenient centralized management, user inspection, fire inspection, extended lamp life, and improved emergency evacuation efficiency. The system is reliable and used. Long life, convenient maintenance and management, and low system price. However, centralized power supply centralized control type emergency luminaires have no backup power supply (battery) in each emergency luminaire. If the power supply line fails, it will directly affect the normal operation of the emergency lighting system, so special fire protection requirements are applied to the power supply line. .

Since the power supply independent control type emergency luminaire has a backup power supply (battery) in each emergency luminaire, there is no special requirement for the power supply line, and the power supply line failure does not affect the standby power supply. When the emergency light fails, it generally affects only the lamp itself, and has little effect on the whole system.

When selecting emergency lighting, the emergency lighting system should be selected according to the specific circumstances. Generally speaking, new construction projects or projects with fire control room should be unified in the construction process as much as possible, and centralized power supply centralized control type emergency lighting should be selected; for small sites, later rectification or secondary decoration renovation projects should be selected with power supply. Independently controlled emergency lighting.
