DD669AM, 20m Ceiling Mount DT Detector with Active IR Anti-Mask (18 Curtains)

DD669AM, 20m Ceiling Mount DT Detector with Active IR Anti-Mask (18 Curtains)

The DD669AM is a dual technology ceiling mount motion  sensor with anti-masking. It will prevent attempts to mask  the sensor while reporting these attempts to the panel.  Its 18 curtains offer maximum detection including full  undercrawl detection capability throughout  a protected  area of up to 20m in diameter.  The unique mirror optics  technology is a step and gliding focus, which creates  continuous curtains that never loses track of the intruder.

The DD669AM features “4D signal processing” which  makes an effective discrimination between intruder and  false alarm signals. Recognizing the diversity in security  applications, the DD669AM also features Bi-curtain  processing for harsher environments.  The combination of  mirror optics with 4D signal processing not only provides  better detection but also increased stability and rejection of  false alarms.
