Abstract

The surrounding fence has a wire mesh structure in which an electrical resistance is incorporated. This electrical resistance can be, for example, a resistance wire (4) which is surrounded by a plastic sheath (5) of the wire mesh structure. In order to reinforce the wire mesh structure, a steel wire (6') can be incorporated in the plastic sheath (5) in addition to the resistance wire (4). The resistance wire (4) is arranged in an electrical resistance measuring circuit (R1, R2, R3, R4, 3) so that an alarm signal is triggered by the resultant change in the electrical resistance values (R1, R2) if the wire mesh structure is damaged. Such a wire mesh structure makes it possible to trigger an alarm signal even if only a single mesh is damaged.
