Residential & commercial applications
The installation recommendations described in this section are intended for sites that do not have
a sterile zone, and where the space available for the sensor cable is often at the limit of the
minimum separation distances. For non-sterile zone applications the following points must be
carefully examined with respect to the site conditions:
• sensor cable selection
• sensor cable spacing
• sensor cable burial depth
• sensor cable path selection
• buried water pipes and electrical cable avoidance
• protection against gardening and landscaping damage
Single vs. dual trench selection
Senstar recommends using dual trench installation with 1.5 m (5 ft.) cable spacing, whenever
possible. However, for applications where the available installation space is limited and the
required separation distances from obstacles cannot be met using dual trench installation, it is
recommended that narrow cable spacing be used. Both OC2 and SC2 sensor cable can be
installed in a single trench, using 10 cm (4 in.) cable spacing.
Sensor cable burial depth
For most natural soil areas, including lawns a burial depth of 23 cm (9 in.) is recommended (see
Sensor cable burial depths
on page 36). A shallower burial depth of 15 cm
(6 in.) is recommended for installation in heavy soil types. For installations where the cable burial
depth has to be raised slightly to avoid a pipe or cable, the change in depth should be made
gradually over a distance of 1 m (3 ft., 3 in.).
Sensor cable path selection
A compromise must sometimes be made between the need for a detection zone which affords the
maximum advanced warning, and the avoidance of obstacles which can impair the system’s
performance.
Note Contact Senstar Customer Service if you are considering using SC1
sensor cable.
Note Monitor the accuracy of the burial depth closely during the sensor cable
installation.
Note Avoid burying sensor cables close to young trees. As the roots grow,
they can displace and damage the sensor cables.
