This manual introduces the concept of pressure difference, the necessity of fire emergency evacuation pressure monitoring system design, system composition, working principle, installation and debugging.
The GST-SCS series is a fire emergency evacuation residual pressure monitoring system that combines industrial computer technology, communication, anti-electromagnetic interference, digital sensing technology and a fire two-bus. It uses high-sensitivity differential pressure sensors to automatically inspect and collect residual pressure changes in monitored areas 24 hours a day, issue alarm signals for over-standard residual pressure and record them.
When the residual pressure in a smoke-proof stairwell or front room exceeds the monitored value, the detector sends an alarm and the controller opens the bypass valve in the positive-pressure air supply system through the electric pressure relief air valve actuator. The system includes a monitor, controller, detector, electric pressure relief air valve actuator and dedicated monitoring software, and the document also lists design standards and technical parameters for the GST-SCS-M101 monitor and GST-SCS-C201 controller. This manual is written in Chinese.

It is the pressure difference between the front room or enclosed refuge floor/room and the corridor, and between the stairwell and the corridor.
GB51251-2017 states a pressure difference of 25 Pa to 30 Pa.
GB51251-2017 states a pressure difference of 40 Pa to 50 Pa.
It can connect and manage up to 110 residual pressure controllers.
