Mechanical Adjustments
A. THE WIDTH OF THE SENSING FIELD IS DETERMINED BY THE CHOICE OF THE PLANAR ANTENNA (OPTION)
Wide sensing field:
3-element antenna
Narrow sensing field:
6-element antenna
SENSING FIELDS ACCORDING TO THE TYPE
OF ANTENNA
The sensing fields above correspond to the
following adjustments:
vertical angle of the antenna: 30°
sensitivity: 9
Mounting height: 7’
B. THE POSITION OF THE SENSING FIELD IS DETERMINED BY THE VERTICAL TILT ANGLE OF THE ANTENNA
SENSING FIELDS ACCORDING TO THE
VERTICAL TILT ANGLE OF THE ANTENNA
The sensing fields on the right correspond
to the following adjustments:
wide sensing field antenna
vertical angle of the antenna: 0°, 20°, 45°
sensitivity: 9
Mounting height: 7’
Carefully remove the
protective cover of the antenna
with a screwdriver.
Change the antenna and
replace the protective cover.
Sensing field as close to the door
as possible:
-antenna set at the position of 0°
Sensing field close to the door:
-antenna set at the position of 30°
Sensing field far from the door:
-antenna set at the position of 45°
