d) Handling, operation
• Use the product only in a temperate climate, never in a tropical climate.
• Do not use the product if it is damaged. There is a risk of a life-threatening electric
shock!
• If it can be assumed that safe operation is no longer possible, the device must be
turned off and precautions are to be taken to ensure that it is not used unintentio-
nally. Do not touch the product.
First switch off the mains voltage to all poles (switch off the connected circuit
breaker or remove the fuse and then switch off the connected RCD).
After this, arrange for a skilled electrician to check the product.
• Safe operation can no longer be assumed if:
- the product shows visible signs of damage
- the product does not work at all or well (flickering light, leaking smoke or a
smell of burning, the light flickers, audible cracking noises, discolouration to the
product or the adjacent surfaces.)
- the product was stored under unfavourable conditions
Function of the ceiling-mounted motion detector
The PIR sensor integrated in the ceiling-
mounted motion detector responds to tem-
perature changes within the detection range,
e.g., if a person or an animal, with a tempe-
rature different from the background, enters
the detection range.
Installing it at a height of approx. 2.4 m crea-
tes a conical detection zone with the diame-
ter of approx. 6 m at the ground.
The range for detecting motion is determined by several factors:
• The ceiling-mounted motion detector's installation height
• The temperature difference between the moving object and the background (ambient)
• The size of the object
• The distance of the object from the ceiling-mounted motion detector
• Direction and speed of the movement
• Ambient Temperature
The detection range can be restricted by covering the concave diffusion panel of the ceiling-
mounted motion detector with an opaque cover such as a strip of black insulating tape.
After switching on the mains voltage, it takes about 30 seconds until the PIR sensor in the
ceiling-mounted motion detector has adjusted itself to the background temperature and is able
to recognise changes in temperature within the detection range.
Preparations for installation
Please observe the chapter „Safety instructions"!
• Only install the motion detector on a stable surface. Use screws and plugs that are suitable
for the surface. Only use the ceiling-mounted motion detector when it is firmly mounted.
• When mounting, ensure an adequate distance to heat sources (e.g. a lighting fixture).
• The ceiling-mounted motion detector must be installed such that it is out of the reach of
children.
• The ceiling-mounted motion detector has to be protected by a 10/16 A fuse on the sub-
distribution board. An earth fault circuit interrupter must be installed before this (FI protective
switch).
• The ceiling-mounted motion detector must be installed only when it is voltage-free. It is not
sufficient to simply turn off the light switch!
Switch off all the poles of the mains cable by removing the corresponding fuse or switching off
at the circuit breaker. Then, switch off the associated earth fault circuit interrupter (breaker).
Secure it against unauthorised reconnection, e.g., with a danger sign.
• Check that the mains connection is free of current, i.e. with an appropriate tester.
Installation and connection
Pay attention to the information in chapter „Preparations for installation"!
• Start the assembly by turning the cover on the under-
side a bit to the left counter clockwise (see the arrow in
the figure on the right) and removing it.
• Remove the outer insulation of the power supply cable
for a length of about 2 cm.
• Remove the insulation of individual wires for a length of approx. 5 mm.
• Guide the cables through the openings in the ceiling-mounted motion detector (pre-cut plastic
parts may have to be removed carefully).
If both cables are laid beneath the plaster, break out the two round plastic parts in
the bottom.
If cables are laid on plaster, you can break out the two round plastic parts on the
edge.
• Fasten the ceiling-mounted motion detector with
two screws and plugs to the room ceiling (interval
between holes 64 mm).
When drilling mounting holes or screw-
ing into place, ensure that no existing
electrical wires, gas or water pipes are
damaged.
• Connect the mains cable and the cable to the consumer
with the spring clips in the ceiling-mounted motion detec-
tor.

Caution!
The ceiling-mounted motion detector is designed according to protection class II and
does not require a protective earth wire.
However, if the device connected to the output of the motion detector requires a pro-
tective earth wire (device is designed according to protection class I), the protective
wire must be connected to the device.
Due to the small size of the motion detector there is no space for corresponding
screw terminals inside the motion detector.
Important!
A device designed according to protection class I must be connected to a protective
wire. Failure to observe this poses a danger to life from electric shock in the fault
case!
Carry out connection and installation of the device and motion detector correspon-
dingly.
• After setting power-up time to „TIME" and brightness control to „LUX" by the dial (see next
chapter) replace the cover removed at the beginning; turn it a bit to the right clockwise until
it locks in place.
• Switch on the power. The device will switch on briefly, switch off and then switch on for 30
seconds. In this time, the PIR sensor in the motion detector adjusts itself to the background
temperature.
• After 30 seconds the motion detector switches off; now it is ready for operation.
• If the PIR sensor detects a change of temperature in the coverage area, the device is activa-
ted (depending on settings of the dial, see next chapter).
