The residual pressure transducer is a device used to detect the air pressure of the fire exit. Usually, the air pressure of the fire exit needs to be higher than other rooms and areas to prevent the smoke and harmful gas from overflowing into the fire exit. When the pressure value of the device is lower than the normal value, it means that there is a safety hazard risk in this fire passage.
