Steinel DALI-2 APC UP

Twice as vigilant. High-frequency corridor sensor Presence Control PRO DUAL HF DALI for indoors, ideal for passageways and long corridors, installation height up to 3.5 m, with digital DALI interface for controlling 2 lighting channels. DUAL-HF technology allows for radial detection of 20 m in two directions, detecting movement regardless of temperature. HF-sensor technology also detects movement through glass, wood, and stud walls, switching light on almost instantly.

A corridor sensor that points the way, both in technology and design. The Dual HF corridor sensor works with particularly advanced high-frequency technology. The system is fitted with 2 sensors, each covering one corridor direction. Together, they cover a good 20 metres in walking direction for complete and reliable detection without blind spots. Tangential reach is deliberately limited to corridor width to avoid detecting movements behind closed doors, for instance.
