The SIEM presence detector from Siemens is a highly advanced passive infrared sensor designed for ceiling mounting. With a horizontal detection range of 360°, it provides comprehensive monitoring of up to 400 m², depending on the mounting height. The detector features an adjustable range setting that allows for individual customization of the detection range. Additionally, the device measures both brightness and temperature, enabling precise adaptation to environmental conditions. The integrated IR receiver and IR decoder allow for control via an IR remote, while an LED display indicates detected movement. Easy commissioning is supported by an easily accessible programming button. The presence detector is designed to operate on bus voltage and can be installed in various mounting options.

• Motion detection up to 400 m², depending on mounting height
• Integrated brightness and temperature measurement
• Range adjustment for customizing the detection range
• IR receiver for remote control operation
• Compatible with KNX smart home systems.
