Gira KNX Motion Detector 1.10m Anthracite 204028

The Gira KNX Motion Detector 1.10m Anthracite is a flush-mounted indoor motion detector for KNX bus systems, offering reliable presence detection and integrated brightness measurement for automatic lighting control. It detects movement within a 180° angle and up to 20 m diameter at the recommended mounting height of 1.10 m.

Advantages

Integrated brightness sensor with adjustable threshold from 10 to 1000 lux enables daylight-dependent switching. Three independent channels can be configured for switching, dimming, or scene control via ETS5 or higher. Logic functions such as AND and OR are integrated, and sensitivity is adjustable via ETS. The anthracite thermoplastic housing fits Gira System 55, E2, Event, Esprit, and ClassiX frames.

Suitable for

• Indoor presence detection in corridors, stairwells, offices, and living areas
• Automatic lighting control based on movement and ambient light
• KNX installations requiring multi-channel control and logic functions
