SuperDuct detectors feature removable dust filters, conformally coated circuit boards, and optional water-resistant gaskets to keep contaminants away from components. They include industry standard sampling tube mounting holes to simplify retrofit applications. SuperDuct detectors use differential sensing to prevent gradual environmental changes from triggering false alarms. A rapid change in environmental conditions, such as smoke from a fire, causes the detector to automatically signal an alarm condition but dust and debris accumulated over time does not change alarm sensitivity.\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003eThe relay output may be configured for operation independent of the duct detector. A dedicated dirty\/trouble LED on each unit offers immediate at-a-glance information even when the cover is closed. The controller can be installed up to 15 feet from detector and one controller can support up to two detectors. Up to 15 controllers can be interconnected for multiple fan shutdown. Remote Test\/Reset stations are available to provide alarm testing and indication from a remote location. Two-wire SuperDuct detectors are also compatible with 5956A remote alarm LEDs.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch4 class=\"item-header\"\u003e\u003cstrong\u003eMain Features\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cul class=\"mainfeatureslist\"\u003e\n\u003cli\u003eLess than 2\" deep\u003c\/li\u003e\n\u003cli\u003ePCB mounted photoelectric detector with on-board intelligence\u003c\/li\u003e\n\u003cli\u003eEnvironmental compensation with patented differential sensing\u003c\/li\u003e\n\u003cli\u003e100 ft.\/min. to 4,000 ft.\/min. air velocity rating\u003c\/li\u003e\n\u003cli\u003eStandard RJ45 modular interconnection\u003c\/li\u003e\n\u003cli\u003eStatus LEDs visible through clear cover\u003c\/li\u003e\n\u003cli\u003eCover tamper reed switch for added security\u003c\/li\u003e\n\u003cli\u003eStandard sampling tube and mounting holes\u003c\/li\u003e\n\u003cli\u003eInstall in tandem with the controller assembly, or remotely from it\u003c\/li\u003e\n\u003cli\u003eMagnet-activated test\/dirty\/reset switch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Edwards Signaling","offers":[{"title":"Default Title","offer_id":43247312404545,"sku":"ED-SDST","price":117.4,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/2465\/9009\/files\/2d9afd8e-ed-sdst.jpg?v=1770768198","url":"https:\/\/www.fireandsafetyplus.com\/products\/edwards-signaling-sd-st-sd-series-superduct-4-wire-smoke-sensor-with-terminals","provider":"Fire and Safety Plus","version":"1.0","type":"link"}
