STEINEL IR Quattro HD 24m DA läsnäolotunnistin passiivi-infrapuna (88835)

The IR Quattro HD 24m DA stands out with its high-density 4800-zone lens, delivering precise presence detection across a 24 x 24 m radial area while maintaining a compact ceiling-mounted footprint. Unlike basic motion sensors, it combines DALI-2 input device functionality with constant light control and a basic light function, making it a direct replacement for conventional occupancy detectors in DALI lighting systems.

Highlights

• 360° detection with HD lens and 4800 switching zones
• Presence detection area: 8 x 8 m tangential (64 m²)
• Max radial detection range: 24 x 24 m (576 m²)
• DALI-2 IPD interface for direct DALI bus integration
• Constant light control and basic light function
• Twilight setting range: 2–1000 lux; time setting: 30 s–30 min
• Ceiling flush or surface mount, IP20, white

In daily use

Installed at a recommended height of 2.5–4 m (max 10 m), the IR Quattro HD monitors large areas with a single device. It operates directly from the DALI bus (10.5–22.5 V DC, 0.2 W) and provides one DALI output channel for lighting and one for HVAC control. The sensor adapts to changing daylight conditions and occupancy patterns, reducing energy consumption without compromising comfort.
