Belimo EXT-TN-1066869: Ceiling Multi Sensor, Ambient Light + Motion, 0-10 VDC (light), Relay (motion)
The Belimo EXT-TN-1066869 is a ceiling-mounted multi-sensor designed for measuring light and motion in room and office spaces, primarily used in lighting applications to enhance energy efficiency through lighting control. It has a low-profile design and offers various output signals compatible with Building Management System (BMS) manufacturers.
Key Considerations for Installation:
- Mounting Height: The optimal mounting height for this motion detector is 9 ft (2.70 m), as it directly affects the detection range.
- Fixed Mounting: Ensure the motion detector is securely mounted on a stable surface to prevent false alarms caused by any detector movement.
- Distance to Switched Luminaires: Avoid positioning luminaires within the motion detector's detection area to prevent unintended activation. Also, refrain from mounting the detector above a luminaire to avoid heat interference, which could trigger false detections.
- Mounting Sideways to Walking Direction: For optimal motion detection, mount the detector to the side of the detection area to ensure a vertical cut of detection zones. Directly approaching objects reduce the detection range.
Detection Range Details:
The Belimo EXT-TN-1066869 sensor detects changes in infrared radiation resulting from movement, where the temperature of the person or object differs from the ambient temperature. The specified detection ranges are approximate values and may vary with changing temperature conditions. To ensure reliable detection, there should be at least a 5K temperature difference between the object and its background, and the object's speed should range from 1 to 3.3 ft/s. Avoid placing the sensor near heat sources such as lamps, radiators, and fans to prevent false triggering. The ideal target is a human body approximately 28x10 inches in size.
