当楼宇住宅火灾发生时，人员走向是:室内→走廊→前室→楼梯间。当量较大时，电梯前室和楼梯间的防火门会出现同时开启的情况，这时要求正压送风的流向是:楼梯间→前室→走廊，这样才能起到防烟的效果。

压力传感器根据其传感器结构，分为机械式压力传感器和电子式压力传感器。当楼宇住宅火灾发生时，人员走向是:室内→走廊→前室→楼梯间。当量较大时，电梯前室和楼梯间的防火门会出现同时开启的情况，这时要求正压送风的流向是:楼梯间→前室→走廊，这样才能起到防烟的效果。

电梯前室压力传感器

当消防前室或楼梯间的通风压力或压差超过设定值（前室25~30Pa,楼梯间40-50Pa）时，Working principle of itive pressure air supply pressure sensor: under normal circumstances, the itive pressure air supply fan pressurizes the air supply into the air shaft through the air duct (Green Arrow Direction) , the compressed air is then sent to the front room or stairwell of each floor through the shutters or the air valve. When the ventilation pressure or pressure difference in the fire chamber or Stairwell exceeds the set value (25 ~ 30 PA in the Front Chamber and 40-50 PA in the stairwell) , the pressure sensor located on each floor immediately sends a signal to the by-pass pressure relief valve control box, the by-pass Pressure Relief Valve control box opens the by-pass pressure relief valve according to the pressure
