Its infrared beam detects smoke through light obscuration, while the combined transmitter and receiver connect directly to a conventional detector circuit. Single-ended wiring means only one side of the installation requires wiring.\u003cbr\u003e\u003cbr\u003eDirectional LED crosshair arrows make beam alignment fast and intuitive. The detector offers a 12° field of view and standard coverage from 5–100 m (16–328 ft), with no separate long-range kit required. Automatic sensitivity threshold setting, resistance to building movement and solid-object intrusion, and operation without alarming when saturated by sunlight support dependable performance. The beam can be adjusted 50° horizontally and 20° vertically, and a built-in imager heater is included.","brand":"System Sensor","offers":[{"title":"Default Title","offer_id":68542082875613,"sku":"Kaybee- OSI-R-SS","price":1956.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/9912\/2909\/files\/OSI-R-SS-1.jpg?v=1794561685","url":"https:\/\/kaybeesecurity.com\/products\/system-sensor-osi-r-ss-4-wire-reflected-beam-smoke-detector-with-8-inch-reflector","provider":"Kaybee Security","version":"1.0","type":"link"}
