4. Installation
The Luxa 103 S360-100-12 is designed for ceiling mounting. Ensure the chosen location provides optimal coverage for the desired detection area.
4.1 Mounting Location
- Mount the detector on the ceiling at an optimal height between 2.5 and 3.5 meters for best performance.
- Avoid mounting near heat sources, ventilation systems, or direct sunlight, as these can interfere with detection.
- Ensure the detection area is clear of obstructions.
4.2 Wiring
- Disconnect power at the main circuit breaker.
- Connect the electrical cable to the detector terminals as per the wiring diagram (refer to the product's specific wiring diagram, not included in this general manual).
- Ensure all connections are secure.
4.3 Detection Area and Parallel Connection
The detector provides a 360° circular detection area with a diameter of 12 meters (113 m²) when mounted at 3 meters. For larger areas, multiple detectors can be connected in parallel to extend the detection range.

Figure 3: Detection Area and Features. This diagram shows the 360-degree circular detection area with a 12-meter diameter (113 m²) and confirms the single light channel. It also mentions passive infrared detection for ceiling mounting and the option for detection range extension via parallel switching.

5. Setup and Configuration
The Luxa 103 S360-100-12 comes factory pre-set for immediate use. Fine-tuning and advanced settings can be configured using integrated potentiometers, an optional remote control, or a dedicated mobile application.
5.1 Operating Modes
- Fully Automatic: The detector automatically switches the light ON and OFF based on presence and ambient light levels.
- Semi-Automatic: The light is switched ON manually (e.g., via a connected push-button) and switched OFF automatically by the detector when no presence is detected for a set period.
5.2 Advanced Functions
- Teach-in Function: Allows the detector to learn and adapt to the ambient light conditions.
- Pulse Function: Provides a short pulse signal, useful for controlling external devices.
- Test Function: For verifying the detection range and functionality during installation.
- Staircase Light Function: Specific settings for staircase lighting control.
- Detection Area Limitation: Use the provided protective clips to precisely define the detection zone, preventing unwanted triggering.
5.3 Configuration via Mobile App
The Theben programming app allows for convenient adjustment of various parameters.

5.4 Configuration via Remote Control
Optional remote controls (sold separately) provide an alternative method for adjusting settings.

Figure 7: Compatible Remote Controls. This image displays three different remote control models: theSenda B (Item no. 9070985), theSenda P (Item no. 9070910), and theSenda S (Item no. 9070911), which can be used for configuring the presence detector.
6. Operation
Once installed and configured, the presence detector will operate according to its programmed settings. In fully automatic mode, lights will switch on when presence is detected and ambient light is below the set threshold, and switch off after a set delay when no presence is detected. In semi-automatic mode, lights are manually switched on and automatically switched off.
7. Maintenance
The Theben Luxa 103 S360-100-12 requires minimal maintenance.
- Periodically clean the detector lens with a soft, dry cloth to ensure optimal detection performance.
- Do not use abrasive cleaners or solvents.
- Ensure no objects obstruct the detection area.
8. Troubleshooting
If the detector is not functioning as expected, consider the following:
- No Detection: Check power supply. Ensure the detection area is clear. Verify sensitivity settings.
- Lights Stay On: Check the light switch-off delay setting. Ensure no continuous presence is detected. Verify ambient light threshold.
- Lights Don't Turn On: Check ambient light threshold. Verify power supply. Ensure presence is detected.
- Intermittent Operation: Check for environmental interferences (e.g., heat sources, drafts).
For persistent issues, consult a qualified electrician or contact Theben customer support.
