Real Presence Sensors

Presence sensors use 24 GHz radar to detect very small movements, such as breathing or typing, so the lights stay on while someone is in the room and still. An ordinary motion sensor would time out. The hidden version can sit behind a ceiling or panel; the dual version mounts either recessed or on the surface. Both have adjustable range, time delay and daylight threshold.

Variants

Hidden: 220–240 V AC, 180°/360°, up to 6 m on a wall or 1–4 m radius on a ceiling, mounting height 1–2.5 m (wall) or 2–4 m (ceiling). Dual: 110–240 V AC, 360°, 2–6 m diameter, ceiling 2–4 m. Delay 10 s to 12 min; daylight threshold 3–2000 lux.

Applications

• Washrooms and dressing rooms: Lights that stay on while the room is occupied.
• Studies and home offices: No arm-waving to keep the lights on.
• Kitchens, stores and utility rooms: Hands-free switching with daylight hold-off.
