Functional description
The motion detector sends out signals in the 5.8 GHz range (much like a radar). These
signals are reflected back from surfaces located within the detection range.
The integrated electronic system evaluates the received signals. If there is a motion
within the detection range (no matter if it is a human, animal or objects), the signals
received will change and the switching output of the motion detector is activated.
The range for detecting motion is determined by several factors:
• The motion detector's mounting height
• The size of the object
• The settings of the control dial "SENS" (sensitivity) on the motion detector
• The distance from the object to the motion detector
• The speed of the motion
• Metal objects in the vicinity of the motion detector
The detection range of the motion detector can
be seen in the image on the right .
The horizontal detection angle is 360°, the range
is up to 8 m.
The recommended mounting height from 2.5 m to
3.5 m results thus in a very large detection range,
which extends through the vertical detection an-
gle of 180° up to the room ceiling.
Preparations for installation
• Only install the motion detector on a stable surface. Only use the motion detector
when it is securely mounted.
Important!
If there are metal objects behind/under the mounting location (e.g. steel
beams, plates or similar), the motion detector will not function properly
In addition, the flow in water or sewage pipes may trigger a switching pro-
cess.
If you plan to mount several motion detectors, they must have a minimum
distance of 2 m to each other.
• Walls, furniture or the like will not inhibit the motion detection due to the high fre-
quency technology used. Depending on the material thickness and humidity level,
the degree of permeation can vary or the high frequency signal may be attenuated.

These values should only be seen as guideline values. There may be large
variations depending on the materials and the environmental conditions.
• Ideally, the motion detector should be mounted on a ceiling at a height of 2.5 m to
3.5 m.
Depending on the room type and the desired function, it is also possible to mount it
on a wall.
Make sure in any case that the product is mounted out of the reach of chil-
dren. Children might otherwise open the motion detector, which could cause
a fatal electric shock!
• Keep a distance of at least 1 m to the walls when mounting the motion detector on a
ceiling. A larger distance is recommended for thin walls; otherwise, persons on the
other side of the wall may also trigger a switching process.
The control dial "SENS" can be used to reduce the range if false activations
occur.
Installation and connection
• Make sure you fix the motion detector to a solid base, e.g. masonry. Use screws and,
if necessary, screw anchors that are suitable for the surface.
• Start the installation by removing the large outer cover. In order to remove it, turn it
a little counter-clockwise.
• Remove the insulation on the mains cable and the connection cable connected to the
device. The individual wires of the cables must be stripped over a length of 8 - 10 mm.
• Pass the cables through both openings of the motion detector. The two transparent
360°
rubber gaskets can be pierced directly with the cables.
• Fasten the motion detector with two screws and plugs to the room ceiling.
Caution!
• Connect the individual wires of the mains cable and of
the cable connected to the device with the terminal at-
tachments in the motion detector.
To do this, insert the stripped cable into the corre-
sponding terminal (cable cross section 1.5 mm²).
Only one cable must be inserted into each terminal!

• The protective earth wire (PE, yellow-green cable) must be connected to a different
place (e.g. to an external terminal box) since there is no corresponding attachment
in the motion detector.
Attenuation
• After setting the control dials (see the next chapter), replace the cover you removed
5 - 10%
earlier in this step properly and lock it by turning it clockwise on the motion detector.

Please refer to the chapter "Safety instructions" and "Preparations for in-
stallation"!
The motion detector must be installed only when it is voltage-free. It is not
sufficient to just turn off the light switch!
First switch off all poles of the mains supply by removing the fuse or switch-
ing off at the circuit breaker and then also switch off the associated residual
current circuit breaker. Secure it against unauthorised reconnection, e.g.
with a danger sign.
Check that the mains cable is free of current, e.g. with an appropriate tester.
Pay attention when drilling and tightening the screws that no cables or pipes
are damaged!

If the terminal needs to be disconnected, press the lock with a suitable
screwdriver. Afterwards, the cable can be pulled out again.
Make sure that the function LED and the brightness sensor are behind the
opening of the cover and visible!
The brightness control will not work otherwise!
