The system (1) has a sliding leaf (2) driven by a drive device, which is controlled by an electronic control device. The drive device is arranged such that the sliding leaf is opened after controlling a control device for opening an escape route, when the system is used in the escape route and an emergency route. The control device has a change-over device e.g. program switch (10), for changing a escape direction (11). A sensor (6) e.g. motion detector, cooperates with the program switch for the escape direction. |
