Principle of Operation
Lights, alarms, and many
other things triggered by
movement – for your con-
venience and safety.
At the front door, garage,
terrace or carport, in a
stairway, storeroom or
basement, this SensorLamp
can be installed and ready
for operation quickly any-
where.
The built-in pyroelectric
infrared detector detects
the invisible heat radiation
that is emitted by moving
bodies (people, animals,
Focal points and angle of

etc.). This thermal radiation
is converted electronically,
and switches on the light
fixture. No thermal radiation
is detected through bar-
riers such as walls or
planes of glass. The fixture
is not switched on.
The most reliable motion
detection is achieved by
mounting or pointing the
unit to aim across the
direction in which a person
would walk, and so that no
hindrances such as trees or
walls obstruct the line of
sight.
Important:
Teh max. reach
is best achieved if the top
row of lens segments is
positioned directly under
the housing.
