Read the complete user manual before carrying out the installation and activating the system. Keep
the manual for future reference.
1. DESCRIPTION
This flush-mounted secondary detector registers movement via a passive infrared sensor (PIR). It is most
sensitive to movements passing through the detection area. The sensitivity to movements directly towards the
sensor is about 50% less (see Fig. 1).
The duration of activation is extended as long as movements of persons are detected.
This motion detector is used as a secondary detector to increase the detection area of a master.
The detector comes in the following 4 versions:

Reference code of corresponding master
2. USE
The detector is suitable for controlling lighting.
Be aware of the following during installation:
• Only mount the detector on stable ceilings.
• Hide any moving objects in the detection area by shielding the lens.
• Do not place any lighting closer than 1 m from the sensor (see Fig 2).
• Do not mount the detector in the direct path of a cold or hot air flow (see Fig. 2).
• This product needs to be installed in a flush-mounting box with dimensions according to the CEE7 standard
sheet XIII or XV and a minimum flush mounting depth of 40 mm.
3. MOUNTING
The detector is designed for ceiling mounting. The diameter of the detection area depends on the mounting
height (see Fig. 1).
The detector is mounted as follows:
1. Release the detector from its base.
2. Connect the base as shown in the wiring diagram in Fig. 3 (also see § 4).
3. Secure the base in a standard 68 mm flush-mounting box.
4. Configure the detector (see § 6).
5. Place the detector back onto the base.
4. WIRING
Connect the detector as shown in the wiring diagram in Fig. 3.
Via the S input a maximum of 10 secondary detectors can be connected to one master. Limit the length of the
electric wires to a maximum of 100 metres.

5. CONNECTING DEVICES
This secondary detector can only be used in combination with a master. The master controls the activation and
deactivation of the device(s).
6. CONFIGURATION OF THE DETECTION AREA
The detector is ready for use approximately 1 minute after connection to the electricity grid. The detection area
can only be modified with the SENS potentiometer on the device when the detector has been switched on.
7. DISPLAY
The statuses pictured below are shown on the indication LED on the device.

Solution
• The daylight level is too high. Lower light sensitivity.
• Check the lighting and the fuse.
• Check the mode of the master (AUTO/SEMI-AUTO).
• The daylight level is too low. Increase light sensitivity.
• Shield the lens.
• The detection range is too wide. Decrease the detection range.
