It uses a photoelectric detection chamber to identify smoke aerosols associated with both smoldering and some flaming fires. When programmed for high sensitivity, the detector meets NFPA 76 requirements as a VEWFD for telecommunications facility fire protection. It mounts on DB-series bases and communicates over the signal line circuit.\u003c\/p\u003e\n\u003cp\u003eVerify panel\/device family compatibility before ordering.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":52004354457893,"sku":"FDOOT441","price":149.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/7648\/4645\/files\/siemens-smoke-detectors-default-title-siemens-fdoot441-multi-criteria-fire-alarm-smoke-detector-35138090172640.jpg?v=1771296314","url":"https:\/\/fastalarmdistribution.com\/products\/siemens-fdoot441","provider":"Fast Alarm Distribution","version":"1.0","type":"link"}
