This sensor is a DALI-compliant device developed to operate seamlessly with the latest DALI-2 specification, enabling precise monitoring of both ambient light levels and occupancy within indoor spaces. Its wide detection angle of up to 125° allows coverage of areas measuring up to 141 m², making it suitable for offices, meeting rooms, corridors, and other commercial or institutional interiors. The device supports remote control via infrared interaction, allowing users to adjust settings conveniently without direct access to the sensor. Additional configuration is possible through dedicated software, which provides individual parameter adjustments to match specific application requirements.
Power is supplied directly via the DALI line, simplifying installation and integration into existing lighting control systems. The sensor is compatible with a wide range of accessories, enabling extended functionality and flexibility for various lighting scenarios. Its compact dimensions allow for discreet integration into luminaires, maintaining aesthetic continuity while providing intelligent lighting control. The SSM version (28004637) offers a pre-configured bundle combining the SFI sensor (28003808) and ACU IP20 housing (28001874), facilitating a simplified setup and quick deployment.
The device features a PIR sensor capable of detecting motion with a 125° angle and measuring light with a detection range between 0.5 and 2000 lux and angles between 80° and 150°. It operates at a supply voltage of 9.5–22.5 V via the DALI cable, with a starting time of ≤30 seconds. The sensor is designed to work effectively at mounting heights of 2–4 meters, with luminaire hole diameters of 23 mm and compatible housing thicknesses ranging from 0.75–4 mm. It is capable of detecting temperature differences of ±4 °C between ambient and target objects, ensuring accurate motion detection.
The housing of the sensor combines durability with a sleek design. The body is made from polycarbonate (PC) in black, while the lens is polyethylene (PE) in white, providing both robustness and unobtrusive aesthetics. The device is rated up to IP54, making it suitable for indoor environments with occasional dust or moisture exposure. Storage conditions range from -25 to 60 °C, and the sensor comes with a five-year guarantee, emphasizing its reliability and long-term performance in professional lighting applications.
Overall, this sensor delivers comprehensive occupancy and light monitoring capabilities in a compact, versatile, and fully DALI-compliant form factor. Its combination of wide coverage, flexible configuration, remote control functionality, and accessory compatibility ensures suitability for a broad range of indoor lighting installations while maintaining ease of integration and aesthetic discretion.
