Passive infrared sensor

Advertisement

Avoid installing the unit in the following places.
Otherwise, non-detection and/or false detection may occur.
• Places subject to strong direct or reflected light (sunlight, spotlight)
• Places subject to rapid temperature fluctuations (air outlets of
air-conditioning equipment, etc.)
• Places where moving objects are included in the protection area
(plants, laundry, etc.)
• Places subject to strong vibration and/or electric noise
• Places where pets, such as dogs and cats, and/or automatic
cleaning robots may pass
• Places where shielding objects (including glass and transparent
resin, etc.) are placed in the protection area (shading parts will not
be detected)
• Places that people can easily touch.
Facing the window
Passive infrared sensors are designed to detect changes of
far-infrared ray energy. Energy changes largely when the human
body moves across the detection area. However, energy does not
change so much when the human body
comes closer in a straight line, or stops.
In addition, if the environment of detection
area generates similar changes due to certain
factors, the unit will issue an alarm without
being able to judge properly.

AREA ADJUSTMENT
The area of protection is adjusted to allow for different mounting hights.
By moving the inner unit upwards, the coverage of the sensor is
decreased.
・The area can be adjusted
independently 90°each side to side
・Hole the inner unit to move.
・Check operation whenever the
protected area is changed.
AREA LOCK
After adjustment, lock the inner unit
with the provided area lock screw.
