Typical Smoke Control System Solution.
In case of a fire on Floor 2:
Ventilation system: fire-resisting dampers KP and block the floor 2 (closed), thus containing the fire and smoke at the ignition floor, fire-resisting dampers KP and remain open enabling pressurisation of the adjacent floors 1 and 3 by the supply ventilation system while fire-resisting dampers KP and in the exhaust ventilation branch remain closed.
Smoke control system: smoke extraction is handled by the VKDV (VKDH) fan via the open KPDU , damper, the supply air is fed from the air pressurisation system via the open damper while dampers , , and remain closed.
