Mini detector


The mini detector detects movement and changes in light intensity. Using this information Niko Home Control functions can be activated or deactivated. The product is suitable for ceiling mounting in suspended ceilings, both indoors and outdoors.


1    Lens

2    Spring clips

3    Shields

4    Cord end terminals



The mini detector detects movement by using Passive Infrared Technology (PIR).

Whenever the detector detects movement the start behaviour of a programmed action will be carried out. If no movement is detected after a set time (e.g. once everyone has left the room) then the programmed stop behaviour will be activated. The start and stop behaviour for the actions is programmed using the Niko Home Control programming software.

The mini detector is also equipped with a photo cell measuring incoming light intensity. When programming you decide whether only to take incoming light or movement into consideration or both of these aspects. This means you can choose to start an action every time movement is detected or only during the day or in the evening. Alternatively you can choose only to take incoming light intensity into consideration and not movement.

A few optional applications:

  • as a presence detector (automatic on/off using mini detector): the mini detector switches on the lights automatically, depending on the chosen lux value and/or whether it detects movement.
  • as an absence detector (manual on using push button /off automatically using mini detector): you switch on the light with a push button and the mini detector switches off the lights when no more movement is detected over a set period.
  • as a light sensor (automatically on/off using mini detector): the mini detector automatically switches on the lights once the light in the room goes below a set lux value and switches off again on reaching the set value.

More information about this and other programming can be found on

The detector calibrates automatically once connected to the bus. After about 40 sec. it is ready to use. The programming remains intact even after a disruption to the current and the detector will continue to work properly.

Detection area

The recommended mounting height is 2 to 3 m. When installed at a height of 3 m the mini detector has a detection range of m diameter (when the sensitivity to movement is set to “high”).

The above table is relevant to the “high” setting. Should the detector's sensitivity be set to “medium high”,“medium low” or “low”, then the detector will be less sensitive to movement (heat transfer) and the detection area will be reduced.

The mini detector is most sensitive to movements passing through the detection area.

Detection angle

The mini detector has a detection angle of 360°. The detection angle can be reduced to 180° by using the shields supplied (in white or black). The shields may be rotated 360° around the lens and can be cut down to size.


The mini detector is designed for flush installation in suspended ceilings

To install the mini detector:

1    Make an opening with a diameter of 3 cm in the ceiling.

2    Connect the mini detector to the two-wire bus cable using a standard connector (not included). To do this use the two wires that emerge from the top of the detector. These are 50 cm long, have a diameter of 0.5 mm² and the ends are fitted with cord end terminals with a diameter of 1 mm and a length of 8.8 mm.

3    Bend the spring clamps upwards and insert the mini detector carefully into the opening in the ceiling. The spring clips make it easy to fix the device.

Do not install the mini detector in the vicinity of heat sources, air currents from ventilation systems or moving objects. These may set off the mini detector.


You can determine and modify the settings of the mini detector in the Niko Home Control programming software. The following three settings can be modified:

  • the light level (2 – 25,000 lux)
  • the sensitivity to movement (“low”,“medium low”,“medium high”, “high”)
  • the switch-off delay.

In the software you can determine which action should be carried out upon reaching a particular light intensity and/or with movement.

Once in operation, users are free to adjust the light sensitivity and switch-off delay of their mini detector in the Niko Home Control user settings software.


Once you have installed the mini detector in the ceiling and followed the steps "Project information", "Creation" and "Cabinet set-up" in the programming software you end up in the step “Realisation”. Here you will be asked to address all inputs individually.

As soon as you start the addressing the green light on the mini detector will start to flash. The mini detector will only pass on an address when detecting a significant difference in light intensity. This kind of difference in light intensity is made by shining a torch onto the mini detector (when there is little light in the area) or by covering it (when there is lots of light in the area). As soon as the address has been sent correctly the green LED will start to shine continuously.

Addressing is also possible by entering the unique MAC address manually in the programming software. You can find this MAC address on the mini detector.
