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.
