STEINEL True Presence COM1 High-Frequency Flush-Mount Presence Detector, Master, 230 V, Relay Output, 360° Detection, 9 m Range, IP20, Bluetooth Configuration, White 85575

The STEINEL True Presence COM1 is a high-frequency presence detector for flush-mount installation in walls or ceilings. Its True Presence technology detects micro-movements such as breathing, ensuring lights stay on even when occupants are stationary.

Advantages

True Presence detection prevents false switch-offs during quiet work. The 360° detection angle covers up to 9 m in diameter from a mounting height of 2.5 to 4 m. Bluetooth configuration via app allows precise adjustment of time and light thresholds. As a master unit, it can be networked with slave devices for larger areas.

Suitable for

• Offices and meeting rooms
• Classrooms and lecture halls
• Corridors and restrooms
• Any space where occupants remain still for long periods
