Abstract (en)

[origin: EP2508813A2] The method involves supplying air to an area (1) via an air supply duct (2) and exhausting exhaust air from the area via an exhaust air duct (3). The supply air and/or the exhaust air are controlled by a controller (12) and/or air pressure is maintained with a reference value in the area. Quenching gas is introduced into the area in case of fire, and the air pressure in the area is controlled by another controller (13) during introduction of the quenching gas. The former controller is deactivated if the latter controller is activated. An independent claim is also included for a device for controlling air pressure in the area.
