4.1 Radio optimization
The wireless Bluetooth Low Energy (BLE) interface is based on the Bluetooth 4.0 protocol.
Connectivity range: ≤15m

1) Do not place any mains voltage or LED supply wires within or close to this area
2) Recommended minimal distance to metal parts
3) Placement of integrated radio transmitter antenna
4.2 Guidelines for control placement to optimize the stability and effective range of the BT connection
1. Preferable installation on systems free from metal obstructions or material that heavily weakens the radio frequency
signal (e.g. fiber-reinforced plastic).
2. Do not place inside metal boxes!
3. Keep a distance of at least 1 cm between the antenna area and the mounting surface.
4. Do not wire cables (mains voltage, LED supply wires) near the antenna area and, if possible, outside of the device
border.
5. Consider an installation height above the furniture and people obstacles (e.g.: 1.6 m from the floor). This is important
for the wireless communication between controllers (Swarm). The wireless range between the controllers is smaller
than between a controller and a smartphone because the controllers are partly surrounded by metal housings while
the smartphone is not.

4.4 Function validation
To validate the assembly, the construction must be checked and the connection stability and connection distance tested.
The check should be done using:
—The OSRAM BT app and a mobile device for testing the range of the mobile device to the BT the antenna
—In case of Swarm function: A second BT control unit to test the point-to-point range between Swarm participants
Please note:
The result of the validation is not an index of replicability in all environments and application situations.

5.2 Sensor size and assembly options for luminaires
The sensor has a small size and it is optimized for luminaire
integration.
There are two different covers available, but there is also
the possibility of individually fitting the sensor into the
luminaire housing:
50 mm (± 0,2)
17 (± 0,2)
57 mm (± 0,2)
20 (± 0,2)

A: Cover (2) for installing the sensor externally
through the opening (1) in the luminaire housing
The cover is placed on the sensor prior to installing the
sensor. Then both parts are inserted into the opening
of the luminaire housing together.

B: Cover (2) for installing the sensor internally
The cover is placed on the sensor housing. If the sensor is
in the correct mounting position, the raised surface of the
cover will sit flush in the luminaire opening (1).
C: Internal sensor installation without separate cover
The openings in the luminaire housing (1) must be made to
accurately fit with the sensor (2). For simple assembly on
the corresponding counterpart, there are retaining lugs (9)
on the bottom of the sensor.
5.3 Guidelines for sensor placement to optimize the functionality and the detection area
1. The light sensor measures the sum of daylight and artificial light reflected by a reference surface (e.g. tabletop or
floor). For this purpose, the sensor must be directed as perpendicularly as possible to the reference surface. To
achieve a proper function, the sensor must be placed so that it receives the reflected light of luminaires connected to
the DALI channel.
2. Direct sunlight falling on the sensor has to be avoided, as well as unwanted measurement of the outside brightness
through the sensor. Therefore, the sensor must not be mounted too close to the window. A sufficient change in the
sensor reading through a change in the illumination is only guaranteed if the maximum mounting height is respected.
3. Do not place light directly behind the sensor as the housing is not fully lightproof!

5. Use the integrated shutter mechanism to adjust the
detection pattern according to your individual needs.
4. Keep a distance between each of the sensor-controlled
luminaires of at least the same distance as the installa-
tion height measured from the floor to the sensor.
