BEFORE INSTALLATION
PROTECTION DISTANCE
Protection distance (between sensor/reflector)
*
should not exceed the rated range.
Outdoor protection distance may be reduced due to
the possible effect of mist, fog, frost, rain, or
condensation on the sensor unit cover and reflector
unit, which can cause false alarms.
φA = 0.2×L
<Example>
L = 10m (33ʼ ) : φA = φ2.0m (6.6ʼ)
L = 30m (100ʼ) : φA = φ6.0m (20ʼ)
HEIGHT OF INSTALLATION
Install the sensor at a height of 80 to
100cm(31"to 39") to catch a human
target. (Install vertically so that the
center of the sensor lens and middle
part of the reflector assembly are
placed at the same height.)
POSITION OF INSTALLATION
The optical unit can be adjusted horizontally (±90 degrees) and
vertically (±10 degrees) for various installation types.
(example 1 to 3)
Example 1
INSTALLATION OF MULTIPLE SENSORS
● Multi-level / straight line installation
Do not perform multi-level protection or straight line protection
(3 spans or more), to avoid malfunction or lost alarm.
Straight line protection
(by mounting sensors
back-to-back)

Example 3

Multi-level
protection
In order to use this sensor correctly, thoroughly read this instruction manual and
select the mounting position and protection distance.

OUTDOOR 0.5 to 30m (1.7ʼ to 100 ft.)
INDOOR 0.5 to 40m (1.7ʼ to 135 ft.)
CAUTIONS ON INSTALLATION
Center of
the reflector
※Align the center of the sensor with the center
of the reflector (the middle of the three reflector
plates) and mount them both keeping the
protection line horizontal. When mounting on
a pole, fix each pole mounting plate at the same
height to align the center of the sensor/reflector.
Install the reflector directly, facing the front of the optical unit
as much as possible.
Reflection efficiency of the reflector, due to its nature, decreases
as the angle from the directly facing position increases.
Make sure that angle remains within ±15 ° even if angled
installation is needed. When exceeding this, the amount of
reflected light will be insufficient and it will not operate correctly.
Sensor
MAX15°
In above case, keep the
angle within ±15 °
● Parallel installation
In order to avoid malfunction or lost alarm caused by
interference, keep the distance between each sensor
when installated in parallel as below.
