    Abstract：In this paper，it is suggested to cancel the provision of automatic fire alarm system in the suspended ceiling based on the analysis on combustible types in the suspended ceiling and use of electrical fire monitoring system;The origin and value of the calculation parameters of mechanical pressurized air supply in the stairwell are discussed，including whether the number of floors opened at the same time by the evacuation door is related to the starting mode of fire emergency broadcast.

    Key words：combustibles;electrical fire monitoring system;automatic fire alarm system;number of evacuation doors opened at the same time;mechanical pressurized air supply;evacuation of the whole building;starting mode of fire emergency broadcast;residual pressure monitoring system for positive pressurized air supply

  摘　要：对吊顶内可燃物种类进行分析，结合电气火灾监控系统的使用，建议取消吊顶内设置火灾自动报警系统的规定；对楼梯间机械加压送风量计算参数的来历和取值进行探讨，包括疏散门同时开启楼层数是否与消防应急广播启动方式有关等。
