DALI Light Sensor with PIR Motion Detection (Ceiling Mounted) 
The SRDA9030APIR is a ceiling-mountable DALI light sensor designed for intelligent lighting control within DALI-2 compliant systems. Configurable via a DALI Master program, it provides automated lighting control based on both occupancy and ambient light levels. 

This DALI light sensor connects directly to the DALI bus, meaning no additional power supply is required. Once installed, it can be fully programmed through the DALI Master to suit a wide range of lighting control applications. 

DALI Motion Sensor Functionality and Light Level Detection 
This device functions as both a DALI motion sensor and an illuminance detector, combining PIR movement detection with smart ambient light sensing. 

PIR motion detection triggers lighting control based on occupancy  

Light level sensor measures ambient brightness for automated adjustment  

LED indicator shows system status:  
Red flash = motion detected  
Green flash = DALI signal received from controller  

The integrated design ensures reliable performance in dynamic lighting environments where both occupancy and daylight levels must be considered.

Applications for DALI Motion Sensor Systems 
These DALI sensors are ideal for commercial and professional installations, including: 

Hospitals  
Schools  
Retail environments  
Conference rooms  
Office buildings  
Other commercial lighting control applications  

By using a DALI motion sensor system, lighting is only activated when required, improving energy efficiency and reducing running costs. 

The on-time delay and control behaviour are fully configurable via a DALI-2 compliant central controller or DALI Master system.
