It's 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.\u003c\/p\u003e\n\u003cp\u003eThe DD669 features \"4D signal processing\" which makes an effective discrimination between intruder and false alarm signals. Recognizing the diversity in security applications, the DD669 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.\u003c\/p\u003e\n\u003cp\u003eThe DD669 sensors incorporate a unique radar technology that is range controlled and operates on 5.8GHz frequency. The range control means that no nuisance alarms are generated for movements beyond the detection pattern. The DD669 motion sensors can be flush mounted with the optional accessory 360FM.\u003c\/p\u003e\n\u003cp\u003eThe 360FM ensures a neat integration in the ceiling, making only the top part of the sensor visible.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDual motion sensor\u003c\/li\u003e\n\u003cli\u003eStep \u0026amp; Gliding Focus Multi Curtain mirror optic\u003c\/li\u003e\n\u003cli\u003eRange controlled radar on S-band\u003c\/li\u003e\n\u003cli\u003ePlug-in electronics\u003c\/li\u003e\n\u003cli\u003eSealed optics\u003c\/li\u003e\n\u003cli\u003e4D processing for reduced nuisance alarms\u003c\/li\u003e\n\u003cli\u003eSelectable coverage pattern using mirror masks\u003c\/li\u003e\n\u003cli\u003eAdditional bi-curtain processing for harsh environment\u003c\/li\u003e\n\u003cli\u003eNo adjustment required for different mounting heights\u003c\/li\u003e\n\u003cli\u003eComplies with EN50131-2-4 Grade 2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIf you are matching this to an existing installation, work from the DD669 part number rather than the description.\u003c\/p\u003e","brand":"Aritech","offers":[{"title":"Default Title","offer_id":57549085409653,"sku":"DD669","price":230.6,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0050\/1216\/0612\/files\/DD669.jpg?v=1788539698","url":"https:\/\/wmestore.co.uk\/products\/aritech-ceiling-mount-motion-sensor-dd669","provider":"WME","version":"1.0","type":"link"}
