Taut wire system


SYSCO’s PROTECTIVEFENCE taut wire system is an electronic detection system for the detection of penetration or climbing-over of mechanical barriers. Horizontal wires are stretched between mechanical fixed points and run along the routes. Movements and changes in length of these tension wires are picked up by a sensor post mounted in the center of the zone. Each tension wire has a separate sensor integrated into the post (max 32) that accurately detects the slightest movement.

The evaluation unit monitors the incoming data of each sensor separately and triggers an alarm when certain time and value criteria are exceeded. Our modern microprocessor technology allows alarm threshold and temporal behavior to be separately programmed for each sensor individually. Weather-related influences such as wind and change in length of the tension wires are detected by the electronics and adjusted accordingly. The evaluation unit has four signal outputs, which can be freely assigned to the sensors, allowing several logical sectors to be formed and put out separately. Each sensor has an integrated event counter.
