PIR1 Series Ceiling Mount DALI-2 PIR+Photocell Sensor
The PIR1 Series Ceiling Mount DALI-2 PIR + Photocell Sensor combines PIR motion detection and daylight sensing in a single DALI-2 compliant device for intelligent lighting control. Designed for ceiling-mounted installations, it enables automatic lighting control based on occupancy and ambient light levels, helping improve energy efficiency and occupant comfort in commercial and indoor lighting applications.
Product Introduction
-
DALI-2 Compliant Intelligent Sensor
Fully compliant with the DALI-2 standard, the PIR1 Series integrates seamlessly with DALI lighting systems, ensuring reliable communication and compatibility with DALI-2 controllers, LED drivers, and luminaires.
-
Combined PIR Motion & Daylight Detection
The integrated PIR motion sensor and photocell continuously detect occupancy and measure ambient illuminance, enabling automatic lighting control that responds to both movement and available natural light.
-
Reliable DALI Bus Powered Operation
Powered directly by the DALI bus, the sensor requires no additional power supply, simplifying wiring, reducing installation costs, and ensuring easy integration into existing DALI lighting networks.
-
Efficient Ceiling-Mounted Coverage
Designed for ceiling recessed installation, the sensor provides a detection range of up to 5 meters at a 2.5-meter mounting height, making it ideal for offices, classrooms, meeting rooms, corridors, and other indoor spaces.
-
OTA Support for Easy Maintenance
The PIR1 Series supports OTA (Over-the-Air) updates, allowing convenient firmware upgrades and simplified long-term maintenance while keeping the lighting system up to date.
