The evacuation indication system is an important component of the fire emergency lighting system,used to ensure that evacuation routes,safety exits,and other evacuation routes can be effectively identified and used in the event of a building fire,maximizing the protection of personnel's life safety.In the electrical design work of buildings,in addition to strictly following the current design specifications such as national standards and landmarks,this article intends to discuss some specific problems encountered in the design of evacuation indication systems based on engineering examples,and propose solutions to provide some reference for future engineering practice.
