1.2.2.1
The protected area (site) should meet the following requirements:
a)
maximum height of irregularities shouldn`t 0,3 m;
b)
height of the grass cover shouldn`t exceed 0,2 m;
c)
height of the snow cover shouldn`t exceed 0,3 m;
d)
on the site avoid tall grass (higher than 0,5 m), bushes and trees at a distance less
than 5 m from the boundary of the detection zone;
e)
don`t direct the sensor to surfaces with high reflectivity (metal, reinforced
concrete, etc.), since sensitivity to vibrations and movements against the
background of such surfaces increases essentially;
f)
to exclude getting people and animals into the detection zone, it is recommended
to use a fence around the protected area with a height of 1 m minimum.
g)
when installing the sensor, exclude the water flow near the sensor. The water
sheets should be excluded throughout the detection zone.
h)
it is necessary to exclude traffic movement at a distance of 20 m beyond the
detection zone in the direction of the microwave radiation.
1.2.2.2
A secured room should meet the following requirements:
a)
don`t mount sensors on walls subjected to constant vibrations;
b)
animals, small birds, vibrating or moving objects (vent lights, doors, air-
exhausters, etc.) should not be in the secured room.
1.2.3
Operation frequency is from 9,2 to 9,6
GHz.
1.2.4
To avoid the mutual influence of sensors, they have frequency letters L1, L2, L3, L4,
and L5.
1.2.5
By the sensor the signal should exceed the noise 10 times.
1.2.6
The sensor is ready for operation within 15 seconds after applying power.
1.2.7
The alarm duration is minimum 3 seconds.
1.2.8
The sensor goes back to the standby mode within 5 seconds after alarm.
1.2.9
The sensors ZEBRA-9.30 and ZEBRA-9.30.BT are powered from 10 up to 30 V DC
with the maximum pulsation of 0,03 V. The maximum power consumption is 1 W.
