The dimensions and the detection zone configurations are given for the ideal conditions of
the perimeter area without taking into account the ambient conditions. Practically the
dimensions and the detection zone configurations can differ from the given ones because of
ambient objects, reflecting surfaces and the detection sensitivity.
8.3.6 Take into account that the signal level reflecting from a moving intruder depends on his
visibility (the reflection square). So, for example, the sensor watching from above the
intruder’s movement will be generate an alarm less than the same sensor watching in front or
side -on. That’s why during the sensor installation when the angle between the detection
zone axis and the ground surface is ≥ 45˚, the signal level can be reduced when the intruder
moves in the detection zone. To detect this intruder more exactly, it is necessary to reduce
the operation threshold; it provides the interference decrease.
8.4 Mounting on the wall.
8.4.1 Make the marking in the chosen place as shown in fig.6.2. Fix bracket 2 with screws 6
on wall 1 (3 types of the bracket: indented from a wall at the distance of 120 mm, 350 mm
and 500 mm). Insert the bolt 11 in the slot of ring 8 and fasten the transceiver unit on bracket
2. Loosen nut 9 and point the unit on the necessary direction turning it in a horizontal
surface. Tighten nut 9. Moving the transceiver in a vertical surface relative to ring slot 8,
align the unit in a vertical surface and tighten it with bolt 11.
8.4.2 The sensor can be performed in one of 5 frequency letters L1, L2, L3, L4 and L5 to
eliminate the mutual influence.
ATTENTION!
1. IT IS PROHIBITED TO INSTALL THE SENSORS HAVIG THE SAME
FREQUENCY LETTERS NEXT TO EACH OTHER. Please take into account the
project documents when ordering the sensors with different frequency letters. When
using more than 5 sensors on the object, the application is to prove by trial operation.
2. If the installation method differs from ones given in this User Manual, so the
application is to prove by trial operation.
9 PREPARATIONS FOR THE OPERATION
9.1 Preparation for the operation
9.1.1 Install the sensor according to the item 8 and connect supply and output circuits of the
sensor according to the color marking of cables as shown in Table 9.1.
