  • Security enclosures
    Patent number: 5224430
    Abstract: A security enclosure comprises a flexible sheet of insulating material extending over the whole of the area of the enclosure and carrying lines of electrically-responsive material on each side. The lines on one side of the sheet extend obliquely relative to the lines on the other side of the sheet and are connected thereto at edge portions of the sheet to form a plurality of conductors so dividing the sheet into a number of relatively small areas so that attempted opening of the enclosure changes an electrical characteristic of the conductors. Connectors are provided at an edge portion of the sheet for individually connecting the conductors to a detector for detecting the changes in the electrical characteristic of the lines. The connectors include a switch arrangement which is selectively configured to connect further connectors associated with the detector with selected conductors.
