The general term for emergency lighting fixtures. The fire emergency lighting system mainly includes accident emergency lighting, emergency exit signs, and indicator lights. It is set up to guide trapped personnel to evacuate or carry out firefighting and rescue operations after the normal lighting power is cut off in the event of a fire. However, in daily inspections, it was found that there are many problems in the selection, installation, and use of fire emergency lighting fixtures in the unit. Therefore, the reasonable selection of power supply control and wiring methods for the emergency lighting system, as well as daily maintenance work, directly affects the effectiveness of the fire emergency lighting system. In daily life, it is necessary to conduct regular examinations and take precautions.
