SENSTAR OmniTrax - Mid-cable Obstacles (Cable Bypasses)

Planning the cable path
Page 46 OmniTrax Product Guide
Mid-cable obstacles (cable bypasses)
If there is an obstacle in the cable path along the length of the active cable, you can splice in a
section of non-detecting cable to bypass the obstacle. PVC conduit should be used to protect the
non-detecting cables, if they pass through the obstacle. Some obstacles that may be encountered
include roadways, trees, fences, storage buildings, culverts, streams, ponds, etc.
If it is not possible to go through an obstacle, it may be possible to go around the obstacle. If you
go around the obstacle, be sure to follow the recommended separation distances from obstacles.
Otherwise, cut and terminate the cables 7 m away from the obstacle.

Note The full length of an OmniTrax cable bypass must be defined as a cable
segment and set to Zone 0 via the UCM software.
