Seven levels of sensitivity are available for each individual sensor, ranging from 0.2% to 3.7% per foot of smoke obscuration. Sensitivity is monitored and selected at the fire alarm control panel. The sensor head design provides 360° smoke entry for optimum response to gray or black smoke from any direction. A built-in screen keeps insects from entering the smoke chamber. Due to its photoelectric operation, air velocity is not a factor, except as it affects area smoke flow.\u003c\/span\u003e\u003c\/p\u003e","brand":"Simplex","offers":[{"title":"Default Title","offer_id":52768470565184,"sku":"4098-9701","price":129.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/6466\/0032\/files\/4098-9701.webp?v=1783613521","url":"https:\/\/firealarmsys.com\/products\/simplex-4098-9701-truealarm-smoke-detector-addressable-head","provider":"FIRE ALARM SYS","version":"1.0","type":"link"}
