Operation/Maintenance
The Infrared Sensor is
suitable for switching light
on and off automatically.
The unit is not suitable for
special burglary alarm
systems since it lacks
the tampering protection
prescribed for this purpose.
Weather conditions may
affect the way the motion
detector works. Strong
gusts of wind, snow, rain
or hail may cause the light
to come on when it is not
wanted because the sensor
is unable to distinguish
sudden changes of tem-
perature from sources of
heat. The detector lens may
be cleaned with a damp
cloth if it gets dirty (do not
use cleaning agents).
