2.1.2. The detector can be mounted if the width of the sector is less. In this case if
“Calibration mode” voltage is less than 10 mV, it is necessary to change Rx and Tx position
relative to the support. For example, if Rx and Tx are at the left from the support, turning the
wall bracket relative to the support at 180º, fix Rx and Tx at the right from the support. If it
is not successful and “Calibration mode” voltage is less than 10 mV, it is necessary to realize
the trial operation and according to its results to make a decision about the possibilities of the
detector operation in these conditions.
2.1.3.
Moving objects influenced by wind: wings of gate, bushes, trees branches, etc.
should not be situated
in the detection zone and at the distance of:
± 1,7 m
from the axis connected Rx and Tx at the perimeter length
from 10 to 50 m
;
± 2,2 m
from the axis connected Rx and Tx at the perimeter length
from 50 to 100 m
;
± 2,6 m
from the axis connected Rx and Tx at the perimeter length
from 100 to 200 m
.
2.1.4.
Sector width should not be less than the detection zone one (see
Table 1.1
).
The sensor can be mounted if the sector width is less. In this case the sensor application is
determined by trial operation.
2.1.5.
The range of the sector’s slope is 40˚ maximum.
2.1.6. The sensors
with different channels should be
mounted on the neighbor sectors.
When the sensor is mounted one after another on the sectors, a number of the channels
should be repeated successively from 1 to 4 providing the maximum distance of the sensors
with the same letter.
2.1.7. To increase the detection zone in the height, it is possible to align the sensors in
two tiers. The sensors should have different channels; two transmitters should be installed
from one side of the protected area, two receivers – from another one. The sectors lengths
should be identical.
2.1.9. The sensor can limit the maximum intruder’s speed. If the maximum intruder’s
speed is reduced, the interference immunity will be increased. The manufacture produces the
sensors with the maximum intruder’s speed of 10 m/sec (“high”). You can reduce the
maximum intruder’s speed up to 4 m/sec (“middle”) and up to 1 m/sec (“low”)*. You can
change the intruder’s speed with PC. After that it is necessary to set the alarm sensetivity
again.
e.g. open perimeter area – high intruder’s speed; the zone between a fence and an
auxiliary one (an intruder can’t rush) – middle intruder’s speed; sensor mounting on the
top of the fence – low intruder’s speed.
2.2. TX and RX mounting
2.2.1. Mark the perimeter area for the places where the supports will be mounted. To
generate a 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. To generate the continuous protected boundary, it is necessary to provide the
