APC Schneider Electric KNX ARGUS Presence 180 Motion Detector 630419

The KNX ARGUS Presence 180 is a flush-mounted presence detector that combines precise motion sensing with constant light control, making it an intelligent choice for automated lighting and HVAC management in modern buildings. Its 180° detection angle and three independent channels allow flexible control of lighting, heating, and alarm systems based on occupancy and ambient brightness.

Advantages

This presence detector integrates seamlessly into KNX bus systems, providing reliable detection for both presence and movement. With a passive infrared sensor and adjustable brightness threshold from 10 to 2000 lux, it ensures lights activate only when needed, reducing energy consumption. The time delay can be set from 1 second to 255 minutes, offering versatility for different room usage patterns. Its polar white, UV-resistant thermoplastic housing blends discreetly into ceilings, while the IP20 rating makes it suitable for indoor applications.

Suitable for

• Offices and conference rooms requiring automatic lighting and climate control
• Corridors and staircases with short-term presence needs

Recommendations

For optimal performance, install at a height of 2.2 to 2.5 metres in rooms with ceiling heights up to 3 metres. Configure the three channels via ETS software to match specific room functions, such as constant light control for workspaces or short-term presence for corridors. Combine with KNX actuators for seamless integration into your building automation system.
