Aritech DD669AM 20m Ceiling Mount Dual Technology Detector With Active IR Anti-Mask 18 Curtains. NC Relay Grade 3
Aritech DD669AM 20m Ceiling Mount Dual Technology Detector With Active IR Anti-Mask 18 Curtains. NC Relay Grade 3The DD600 series complement the successful EV600 series PIRs with dual technology motion sensors. The 18 curtains offer a maximum detection capability including full under crawl detection throughout a protected area of up to 20m in diameter.The unique mirror optics technology is a gliding focus which creates continuous curtains that never loses track of the intruder.4D signal processing4D signal processing makes an effective discrimination between intruder and false alarm signals. Recognizing the diversity in security applications the DD600 series features both 4D signal processing and Bi-curtain processing for the 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.Range controlled radarThe DD600 sensors incorporate a unique radar technology that is range controlled and operates on 5.8 GHz frequency. The range control means that no nuisance alarms are generated for movements beyond the detection pattern.Key FeaturesDual motion sensorAutomatic reporting of all masking attemptsStep Gliding Focus Multi Curtain mirror opticRange controlled radar on 5.8 GHzPlug-in electronicsSealed optics4D processing for reduced nuisance alarmsSelectable coverage pattern using mirror masksAdditional bi-curtain processing for harsh environmentNo adjustment required for different mounting heightsEN50131-2-4 Grade 3 certifiedSeveral European approvals
