stair pressurization fan control diagram

The pressurization is used to push back on smoke, keeping the smoke out of the escape route. In case of fire in a high rise building, a Stair Pressurization Fan (SPF) uses clean outside air

If a stairwell pressurization system is being activated by a fire alarm relay module, the wiring to that module must carry a two-hour fire rating (IBC 909.20.6.1). For low-voltage systems, there are fire-rated wiring products available that can still be installed in a raceway system like any other standard fire alarm cable.
