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.
