消防应急照明设计若干问题探讨

Discussion on Some Problems of Fire Emergency Lighting Design

对消防应急照明和疏散指示系统工程设计中存在的过度设计问题给出优化建议方案。建议有备用照明的场所在非火灾状态下不应使用消防应急照明;给出非火灾状态下使用消防应急照明时蓄电池电源持续供电时间推荐值;对防烟楼梯间或封闭楼梯间消防应急照明的配电回路设计进行分析,提出优化做法。

The optimization scheme is given for the over‑design problems existing in the engineering design of fire emergency lighting and evacuation indication system.The paper suggests that fire emergency lighting shall not be used in places with standby lighting under non‑fire conditions;provides the recommended value of battery power supply duration when using fire emergency lighting in non‑fire condition;and analyzes the design of power distribution circuit for fire emergency lighting in smoke‑proof stairwells or closed stairwells,and puts forward optimization methods.
