4 Mounting instructions for BT controls

4.1 Radio optimization

The wireless Bluetooth Low Energy (BLE) interface is based on the Bluetooth 4.0 protocol.

Connectivity range: ≤15m

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.

4.3 Best practice examples

General mounting rules:

 Metal surrounding the antenna

 Wires over antenna area

 No space for free BT transmission

Non-metallic surrounding material

>1 cm of free space around antenna

Space for free BT transmission

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)

0,5 - 2,4

R 0,6 mm (max.)

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!
