Do not install in an
environment subject to
electrical noise or intense
vibration.
Do not install the unit by an
air conditioning exhaust
vent.
Remove all obstructions
Do not install the sensor in
a location in which it is
subject to direct light
sources such as sunlight or
automobile headlights.
The sensor is rainproof,
but not waterproof.
Do not hose or
otherwise directly apply
water to the sensor.
This sensor is set to detect changes in far infrared
radiation energy given off by moving bodies.
Accordingly, please be aware that if there is a
similar change in the detection environment for a
different reason, the sensor may not be able to
make this distinction, resulting in a false
detection.
Depending on their
positioning, zones may or
may not detect people
easily. Position the sensor
so that people pass across
the detection area. If
people enter straight into
the detection area, or
stand still in the detection
area, they may not be
detected.
This sensor is designed to be
mounted on the wall of a
building or on a pole.
Ensure the sensor is installed
the right way up.
Install the unit at the height of
the ground.
Remove all obstacles

Make sure that downward
zone will not be affected by
sun light reflected by water
on the road etc.
Caution
The mounted sensor is inclined upwards.
The detection area slopes downwards

Non detection area
Mount the sensor so that when viewed from the front, the
horizontal zone is parallel to the ground. Additionally,
ensure that the sensor is not at an angle when viewed
from the side.
The detection distance may change because of the following.
higher mounting will increase detection distance).

background heat, therefore detection distances may vary
depending on the season, or upon environmental
conditions.
Please confirm the area layout and detection in
accordance with the actual mounting location by a walk
test before configuring.
Difference in detection distance
Low temperature
difference
If the far edge of the area has a road upon which vehicles
pass, then set the area and detection distance so that
vehicles are not detected.
If there is a road at
the edge of the
detection area, then
cars and motorcycles
that are larger
sources of infrared
radiation than
human body may be
detected even if
people are not.
Adjust the area and
set detection distance
in order that other
than the desired
objects are not
detected.
