STEINEL True Presence COM1 High-Frequency Ceiling Presence Detector, Surface-Mounted, IP54, 360°, Relay Output, 2000 W, White 85537

Detect even the slightest movements with the STEINEL True Presence COM1, a high-frequency presence detector that senses micro-movements like breathing or typing, ensuring lights stay on when someone is present. With a 360° detection angle and a range of up to 9 m diameter (64 m²) for true presence, it's ideal for offices, classrooms, and meeting rooms.

Overview

The True Presence COM1 uses 5.8 GHz high-frequency technology to detect the smallest movements, even through thin walls or partitions. It is surface-mounted on ceilings and offers a relay output for controlling lighting loads up to 2000 W (resistive) or 1000 W (LED). The detection range extends to 15 m diameter (177 m²) for larger movements, and the mounting height is recommended between 2.5 and 4 m. With adjustable time settings from 30 seconds to 30 minutes and twilight levels from 2 to 1000 lux, it adapts to various environments.
