Interlogix DD669-U 20 m Ceiling Mount Dual Motion Sensor

20 m Ceiling Mount Dual Motion Sensor NO/NC Alarm Output, USA. Incorporating advanced mirror optics technology, the Aritech DD669-U Ceiling Mount Dual Motion Sensor uses a unique step and gliding focus feature to create a continuous curtain that ensures sensors never lose track of objects. The DD669-U features 18 curtains for maximum detection capability, including under crawl detection, throughout a protected area up to 65 feet in diameter. Using the combination of mirror optics with 4D signal processing, the DD669-U motion detector effectively differentiates between intruders and false alarm signals. This combination also optimizes the sensor for performance in harsh environments. By incorporating unique, range-controlled radar technology, the DD669-U eliminates nuisance alarms generated by the movement of objects beyond the detection pattern. The combination of mirror optics, 4D processing and unique radar technology provides high sensitivity detection while minimizing false alarms for optimal performance.
