Planning the cable path
OmniTrax Product Guide Page 41
Single/dual cable set separation, one processor
A single cable set cannot cross over itself to create a fully closed perimeter. If the active cable from
a cable set crosses over active cable from the same cable set both location accuracy and target
resolution are severely compromised. Figure 15:
illustrates this concept. Both cable sets from a
single processor are usually overlapped at the start point of the detecting cable. The minimum
separation between any A-side and any B-side detecting cables is 30 cm (1 ft.) for a maximum
length of 12 m (40 ft.).
Obstacles
Obstacles located on or near the proposed cable path can affect the detection field and can cause
security problems. For example, a tall obstacle may be used to bridge the security system and a
metal obstacle can affect the detection field. There are specific rules, which outline the minimum
separation distances between obstacles and the OmniTrax sensor cables. Any obstacles must be
noted on the site plan and the sensor cable path or spacing may have to be adjusted to keep the
separation distances within tolerance. Uniform detection sensitivity and reliable system
performance depend on correct cable spacing and separation distances from obstacles.
Keep the sensor cables as far away from above and below ground obstacles as possible. The
minimum recommended separation distance between the cable route and any obstacle is 1.5 m
(5 ft.). The separation distance is measured from the detection field centerline to the object (see
Separation distances from obstacles
on page 42).

Note If your site includes obstacles that are not covered in this manual, or
you are having difficulty meeting the separation requirements, contact
Senstar Customer Service as there are mitigating installation
techniques.
