The method involves using valves (6.1-6.n) or ventilators (5), which are inserted in main (1) or branch lines (2.1-2.n) of the ventilation unit, simultaneously as fire protection devices. In the case of a fire, the ventilators or valves are automatically controlled to bring them into a position that prevents the transfer of smoke or fire between the individual areas (4.1-4.n) to be ventilated through the lines. An Independent claim is included for a ventilation unit for a building.
