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/stairwell of each floor through the shutters/the air valve. when the ventilation pressure/pressure difference in the fire chamber/stairwell exceeds the set value (25 ~ 30 pa in the front chamber&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
