OB-1501 iDim Orbit
The OB-1501 iDim Orbit with five movement detectors is a standalone, flush-mounted sensor that provides easy
installation and configuration of lighting control applications.
This document describes how to connect the sensor and how to mount it into a ceiling. For information on how to
configure it, see the iDim Orbit App Guide.

Due to the nature of PIR technology, when someone walks directly towards the centre of the sensor, the detection
distance from the sensor is reduced. The point at which the sensor will detect movement is affected by site-specific
conditions, such as speed of movement, clothing and air temperature. Hence it is not possible to guarantee the point at
which the sensor will trigger the loads when someone walks directly towards the centre of the sensor.
When someone walks ‘across’ the detection area, the sensor range is greater than when someone walks towards the
centre of the sensor. Therefore, in applications where occupants are free to move in all directions, such as classrooms
and offices, the detection range shown in the preceding figure can be used when planning sensor positions.

for the manual switch’, on page5.
4. Plug the mains connector and the DALI connector(s) into the sensor.
5. If required, plug the input connector for the manual switch into the sensor.
6. Mount the sensor into the ceiling as shown in section 3.4,‘Mounting the sensor into the ceiling’, on page5.
7. Power the sensor up.
8. Download the iDim Orbit app to your iOS device (iPod Touch, iPhone or iPad).
9. Connect the iDim Orbit app to the required OB-1501 iDim Orbit via Bluetooth®Smart™.
10. Configure the sensor using the app. The default passcode is 00000. For information, see the iDim Orbit App Guide.
3. Installation
Installation Notes
3.1. Mounting the mains connector
• Position the sensor so that the occupants of the room are normally inside the detection zone.
• Do not fix the sensor to an unstable or vibrating surface.
• Do not install the sensor within 1 m of any lighting, forced air heating, or ventilation equipment.
• The external supply must be protected. External protection must not exceed 16 A Type C MCB.

You can use either single-pole or double-pole switches to control DALI channels. This is configured
via the iDim Orbit App. The default is for ‘switch control’ using single-pole switches. For details, see
the iDim Orbit App Guide.
As an example, the following diagram shows:
• A single point of control (switch inputs 2 and 3) using a double-pole switch for DALI channel 1
• Two points of control (switch inputs 5 and 6) for DALI channel 2 using single-pole retractive switches connected in
parallel
• A single point of control using a single pole switch on the relay channel (switch input 4)
