NX-480 Wireless Motion Sensor
Figure 1. Overhead (Bird’s Eye View) Detection Path
■
For best coverage, mount the sensor from 5 to 8
feet high in the corner of the area you want to
protect. See the Animal Alley lens guidelines for
mounting the Animal Alley lens. Higher mount-
ing provides better range (up to 35 feet), and
lower mounting provides better protection close
to the motion sensor (see Figures 2 and 3).
Animal Alley Lens Guidelines
The animal alley lens provides protection in installa-
tions where pets move about freely.
■
Allowed mounting height is between 3 and 5 feet.
■
Position the sensor to have a clear line of sight
across the protected room.
■
For best results, install the sensor higher than the
highest point that the pet might reach in the
detection area.
■
If the detection area contains furniture or other
objects upon which the pet could climb or jump,
either remove these objects, mount the PIR a safe
distance above these objects, or mask these areas.
