FIELD
1. The position of the sensing field is determined by the vertical angle of the planar antenna. The angle is
adjusted in 3
°
increments by gently rotating the antenna forward or back. The default mounting angle is 30
°
-
Patterns shown in diagram below are those at 30
°
.
2. The tilt angle will be greatly determined by the position of the sensor with relation to the face of the door. A 15º
angle will result in the pattern being drawn back towards the door, where as the 45º will place the pattern
farther away. Be certain to walk-test detection field and insure compliance with current applicable ANSI
standards.
1. Insert the desired microwave planar antenna for a narrow or wide field of detection. Refer to the
diagram below for approximation of field size for each pattern.
7’-0” height = [13’ (W) X 6’ 6” (D)] [6 6” (W) X 8’ 2” (D)]
•
The optional narrow-field antenna is located in a slot behind the mounted antenna as shown.
•
To remove the antenna, carefully remove the protective cover and change antenna.
•
Once proper antenna is in place, adjust angle of antenna as necessary.
