STEINEL Dual HF Wireless Ceiling White

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. DALI-2 input device enables sensors to communicate collected sensor data to higher-level lighting management systems.

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