Read the complete manual before carrying out the installation and activating the system. Keep the
manual for future reference. Consult the online programming guide on www.niko.eu for detailed settings.
1. DESCRIPTION
The 360° KNX presence detector with continuous daylight control is ideal for flush-mounted installation in the
ceiling and use in integrated solutions with other KNX system components. The device detects movement and
the presence of persons with the aid of Passive InfraRed technology (PIR). The detector is most sensitive to
movements passing through the detection area (see fig. 1). The sensitivity to movements directly towards the
sensor is about 50% less.
The presence detector is provided with a (2-channel) continuous daylight control function, which adjusts the
light intensity based on the incoming daylight. The detector can also be used for the control of sun blinds, HVAC
and alarm systems, creation of lighting scenarios, etc.
The detector is designed for indoor applications and has an integrated light sensor. It is suitable for use in offices,
production premises, schools, hospitals and public buildings and can be used in both large and small rooms.
The detector is supplied with power by the KNX bus. Communication on the KNX bus follows the KNX principle.
The detector can be configured with the ETS software.
2. USE
The presence detector responds to the heat of moving bodies. As soon as someone approaches the detection
range, the programmed action will be executed. When this same person leaves the detection range, the action
will be stopped after an adjustable switch-off delay. If the standby light is activated, the lamp will stay on at a
lower intensity for an adjustable period of time.
The detector is suitable for use in integrated solutions with other KNX system components.
Be aware of the following during installation:
• Only mount the detector indoors and 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).
• The light source of this luminaire is not replaceable; when the light source reaches its end of life the whole
luminaire shall be replaced.
3. MOUNTING
The detector is designed for ceiling mounting. The diameter of the detection area depends on the mounting
height (see Fig. 1).
Mounting:
1. Connect the black (-) and red (+) bus terminal to the KNX bus (see Fig. 4a and 4b).
2. Secure the detector in a standard 68 mm flush-mounting box.
3. Configure the detector with the ETS software (see § 5).
Meaning LEDs:
• Red LED: glows upon pressing the programming button
• Green LED: flashes once with each motion detection.
4. WIRING
This detector is suitable for connecting to the KNX bus and is powered by a KNX power supply.

Minus (black bus terminal) -
5. CONFIGURATION
The detector is ready for use approximately 1 minute after connecting the KNX bus voltage. Press the programming
button (see Fig. 4c) to activate the detector's programming mode (red LED is burning). The settings can only be
modified while the detector is in programming mode. The detector should be configured with the ETS software.
The product details for configuration of this detector can be downloaded from the product database on our
website (www.niko.eu).

Solution
• The threshold value is set too low. Increase the threshold value.
• Check the lighting and the fuse.
• Check the detection area for possible causes for this error: a draft,
animals, heating etc can all cause erroneous detections
• Check the distance to any lamps (heat reflection or direct incident light).
• If necessary, shield the lens.
• The detection range is too wide. Decrease the detection range.
• The threshold value is set too high. Decrease the threshold value

8. OPERATION AND MAINTENANCE
Dirt affects the operation of the motion detector. The lens must always be clean. Use a damp cloth for cleaning
the lens. Use water mixed with normal cleaning agent. Avoid pressing hard on the lens. If the lens or other
components of the motion detector are defective, it/they must be replaced.
