8. MOUNTING PROCEDURE
8.1.
Requirements to the protected sector preparation and the arrangement of Rx
and Tx.
8.1.1
. The sector, where Tx and Rx are located, should meet the following requirements:
a)
height of irregularities – up to +0,3m.
If irregularities exceed +0,3m, the
sensor characteristics can become worse. Under these conditions the
possibility of the sensor usage is defined by the trial operation.
b)
grass height - up to 0,4m;
c)
snow height - up to 0,9 m; at the sector length less than 50m – up to 1m;
d)
single motionless objects (e.g. posts, tree trunks without lower branches) can
be situated in the detection zone at the distance of 0,5 m minimum from the
detection zone axis;
e)
moving bushes, tree branches, gate wings and etc.
should not be situated
at
the distance of ±1,7 m from the axis connecting Tx and Rx at the sector length
less than 50m; at the distance of ±3,7 m at the sector’s length up to 250m; at
the distance of ±5 m at the sector’s length up to 500m;
f)
the sector width should not be less than the detection zone width (see table
3.1);
The sensor can be mounted if the sector width is less. The alarm of the Rx
output can possibly be very weak or absent.In this case the Rx or Tx antenna
is installed from the other side of the support. Besides, in some cases the
sensors interference immunity can reduce. It can be detected while the trial
operation;
g)
the sector’s length is:
«Forteza-300» - from 10 up to 300m;
«Forteza-500» - from 10 up to 500m;
h)
the sector bias isn’t restricted.
8.2.
Sensor mounting
8.2.1
. Mark the perimeter for the places where the supports will be mounted. To organize
the continuous protected boundary, the installation of Tx and Rx
isn’t permitted
on adjacent perimeter sectors. The right installation on adjacent perimeter sectors
is Tx and Tx, Rx and Rx.
8.2.2.
Mount the supports. It is recommended to use metal or asbestos-cement tubes of
150…200mm diameter as supports. As the sensor doesn’t have «dead» zones, it is
possible to mount two Tx (or two Rx) on every support of adjacent perimeter
sectors.
The supports can be mounted with concreting.
