The supplied motion detector can
“see” up to a distance of about 40 feet
with a 90 degree field of view. It can be
placed up to about 100 feet away from
the console.
You can place the motion detector on
a counter top or use the included
mounting bracket. The bracket lets you
swivel the motion detector for the best
coverage.
Note:
The motion detector senses mo-
tion by detecting temperature chang-
es. To help prevent false alarms, do
not place the motion detector near a
heating or air conditioning vent.
Secure the bracket to the detector’s
bottom using the supplied machine
screw. Then secure the bracket to the
wall. Finally, loosen the screw on the
hinge and adjust the detector to be lev-
el, then tighten the screw to hold the
detector in position.
For the best coverage, place the mo-
tion detector at a height of 6 feet, then
position the lens so an intruder walks
across its path rather than toward it.
Approx 40 ft.
