Fire Suppression Sensors

Pressure Sensors in Fire Suppression Application

In Fire Suppression systems, once a fire is detected, fans are energized creating positive pressurization in the stairwell and negative pressure in exhaust shafts to pull smoke out of the area of fire origin. Both the positive and negative pressures are controlled by variable speed fans and are fed signals from differential pressure sensors that are located within the stairwell and exhaust shaft
