Motion sensor kit PS-MSK2 (optional)
Do not install the motion sensor kit PS-MSK2 (optional) in the
following places.
It may cause misdetection, undetectable of motion or the
deterioration of the motion sensor.
• Places where ambient temperature changes drastically.
• Places where excessive force or vibration is applied to the
motion sensor.
• Places where static electricity or electromagnetic waves may
generate.
• Places where is interference for infrared light such as
glasses or mist in a detecting area.
• Places where the lens for motion sensor is exposed in high
temperature and humidity for a long time.
• Places where fluid and corrosive gas exist.
• Places where direct lights such as sunlight or headlight affect
the motion sensor.
• Places where hot air from a heater, etc. affects directly the
motion sensor.
• Places where weather affects directly the surface of the
motion sensor.
• Places where the lens surface may smudge or be damaged
such as a dusty environment.
Pay attention that the detecting function will be decreased if the
lens for motion sensor smudges.
In this case, wipe off smudges by a cotton swab soaked alcohol
(Isopropyl alcohol is recommended) or a soft cloth.
When wiping off smudges on the lens for motion sensor, do not
apply excessive force.
If excessive force is applied, the resin lens may be damaged
so that may cause malfunctions such as misdetection or
undetectable of the motion.
