The flap (5) has a frame (9) defining a ventilation opening, and a flap drive (8) for actuating flap elements (6). A control device is connected with a communication interface for controlling the drive based on control commands of a control center, and the interface is provided for data exchange with a control center. An integrated sensor (10) e.g. gas sensor, detects danger i.e. fire, within a structure e.g. traffic infrastructure such as road tunnel (1). The sensor is connected with the interface for transmitting sensor measured values to the control center. An independent claim is also included for a tunnel comprising air supply- and exhaust ducts. |
