SENSTAR OmniTrax - Separation Distances from Obstacles

Planning the cable path
Page 42 OmniTrax Product Guide
Commonly encountered obstacles include:
•fences
• buildings and other structures
• roads, walkways, storage areas, parking areas
• surface water (including water that collects after a rainfall)
• underground pipes, conduits or electrical cables
• large metal objects
• large rocks, trees, bushes, dense vegetation
Separation distances from obstacles
The required separation distance between the sensor cables and an obstacle depends on the type
of obstacle and the burial medium. The separation distance is measured from the centerline of the
detection zone to the object.
OmniTrax cables should be placed to avoid obstacles. Obstacles in the detection field may pose a
threat to security and can affect system performance. The detection zone centerline should be at
least 1.5 m (5 ft.) from all obstacles both above and below ground.
Separation distances from pipes, conduits and cables
The following separation distances apply both above and below the sensor cables. The separation
distances indicated are minimum requirements. If more space is available, increase the separation
distance.
Note Avoid burying sensor cables close to young trees. As the roots grow,
they can displace and damage the sensor cables.
