Indoor motion detector
Description
The indoor motion detector detects moving heat sources and activates or deactivates Niko Home Control functions.
Overview
Operation
The indoor motion detector detects moving heat sources by using Passive Infrared Technology (PIR). When motion is
detected, the motion detector activates or deactivates certain Niko Home Control functions. These functions are assigned
whilst programming the installation by linking functions to the unique address of each indoor motion detector.
When a person enters the detection area, the motion detector initiates the starting behaviour. When the person has left
the detection area or remains motionless within the area, the stopping behaviour will be initiated as soon as the switch-off
delay has elapsed.
The indoor motion detector includes a manual mode option. In manual mode, the indoor motion detector will behave as if
there were permanent motion. Press the manual mode button to activate or deactivate this mode. If manual mode is not
deactivated, the function linked to that motion detector will remain active for 4 hours.
Installation
The indoor motion detector consists of two parts: the sensor and the base. The bridge is mounted onto a standard flushmounting
box using screws.

To install the indoor motion detector:
Connect the base to the two-wire bus cable. There are two “B1” contacts and two “B2” contacts at the back of the base. Connect
each individual wire to one “B1” contact and one “B2” contact.
The base is now connected. Use the other “B1” and “B2” contacts to establish a connection to the next control element if required.
Mount the base onto the single flush-mounting box using screws. Use a base with a set of claws if no screw holes are provided in
the flush-mounting box. Two types of bridges are available:
base 60 x 71 mm with claw connection (Belgium)
base 71 x 71 mm with screw connection (the Netherlands)
Press the sensor onto the base until it clicks into place.
Selecting the indoor motion detector settings
Setting the light sensitivity
The indoor motion detector is for indoor use only.
Mount the indoor motion detector at 90 - 110 cm above floor level.
The maximum detection range is 8 m.
Strip the wires of the bus cable 9 - 10 mm.
A maximum of one wire with a diameter of 0.5 - 1 mm can be connected per contact.
In this case, polarity does not matter.

The potentiometer underneath the cover of the sensor can be used for changing the light sensitivity setting to any value
between 5 and 1,200 lux.
To change these settings:
Open the cover.
Use a screwdriver to turn the potentiometer to the desired setting. Turn the potentiometer clockwise to decrease the light sensitivity
(up to a maximum of 1,200 lux or daylight). Turn the potentiometer counter-clockwise to increase the light sensitivity (up to a
minimum of 5 lux or night-time).
Setting the switch-off delay
The switch-off delay can be set in the Niko Home Control programming software. After the installation, the user can adjust this
setting himself in the software.
