A capacitive proximity sensor giving a long front detection range with less erroneous detection. ESD protection is provided by holes through the gasket between the panel and the conductive structure. A card reader is also included and uses one of the magnetic stripes on a debit card. A second fiberglass-based facer that is substantially impervious to the passage of hot gases of combustion through its thickness can form a bottom major surface of the composite. The device according to the present invention is characterized in that it also comprises means for connecting and disconnecting said first plate tofrom said second plate, characterized in that it further comprises a hydraulic system for decompressing said hydraulic lines.
