The i3 family is founded on three principles:\ninstallation ease, intelligence, and instant inspection. The i3 line redefines\ninstallation ease with its plug-in design. This allows an installer to pre-\nwire bases (included with heads). The large wire entry port and in-line\nterminals provide ample room for neatly routing the wiring inside the base.\nThe base accommodates a variety of back box mounting methods as well as direct\nmounting with drywall anchors. To complete the installation, i3 heads plug\ninto the base with a simple Stop-Drop ‘N Lock action. i3 detectors offer a\nnumber of intelligent features to simplify testing and maintenance. Drift\ncompensation and smoothing algorithms are standard with the i3 line to\nminimize nuisance alarms. 2-wire i3 detectors can generate a remote LED\nindicated maintenance signal when connected to the 2W-MOD2 loop\ntest\/maintenance module or a panel equipped with the i3 protocol. The SENS-\nRDR, a wireless device, displays the sensitivity of i3 detectors in terms of\npercent-per-foot obscuration. The i3 series provides wide-angle red and green\nLED indicators for instant inspection of the detector’s condition: normal\nstandby, out-of-sensitivity, alarm, or freeze trouble. When connected to the\n2W-MOD2 loop test\/maintenance module or a panel with the i3 protocol, the EZ\nWalk loop test feature is available on 2-wire i3 detectors. This feature\nverifies the initiating loop wiring by providing LED status indication at each\ndetector.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003e12\/24VDC\u003c\/li\u003e\n \u003cli\u003e2 CABLE\u003c\/li\u003e\n \u003cli\u003eDEDECTOR\u003c\/li\u003e\n \u003cli\u003eI3 SERIES\u003c\/li\u003e\n \u003cli\u003eTHERMAL\u003c\/li\u003e\n \u003c\/ul\u003e","published_at":"2026-03-21T17:16:46+11:00","created_at":"2026-03-21T17:16:42+11:00","vendor":"System Sensor","type":"Smoke Detectors \u0026 Fire Alarms","tags":["home_improvement_Apr2026"],"price":28400,"price_min":28400,"price_max":28400,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":47453901095063,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"B084KHGBQZ","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"SYSTEM SENSOR 2WT-B 12\/24 VDC, 2-Wire, Thermal, with Base, I3 Series, Detector","public_title":null,"options":["Default Title"],"price":28400,"weight":231,"compare_at_price":null,"inventory_management":"shopify","barcode":"2WT-B","requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/newnestshop.com\/cdn\/shop\/files\/B084KHGBQZ.jpg?v=1775812727","\/\/newnestshop.com\/cdn\/shop\/files\/71RVipYTlDL.jpg?v=1774073805","\/\/newnestshop.com\/cdn\/shop\/files\/71-8li3OOeL.jpg?v=1774073805","\/\/newnestshop.com\/cdn\/shop\/files\/71_ZpCDq5PL.jpg?v=1774073805","\/\/newnestshop.com\/cdn\/shop\/files\/71jFcjydi1L.jpg?v=1774073805","\/\/newnestshop.com\/cdn\/shop\/files\/714DH-Y0nuL.jpg?v=1774073805","\/\/newnestshop.com\/cdn\/shop\/files\/715vCBqfCSL.jpg?v=1774073805"],"featured_image":"\/\/newnestshop.com\/cdn\/shop\/files\/B084KHGBQZ.jpg?v=1775812727","options":["Title"],"media":[{"alt":null,"id":41170327502999,"position":1,"preview_image":{"aspect_ratio":0.75,"height":1600,"width":1200,"src":"\/\/newnestshop.com\/cdn\/shop\/files\/B084KHGBQZ.jpg?v=1775812727"},"aspect_ratio":0.75,"height":1600,"media_type":"image","src":"\/\/newnestshop.com\/cdn\/shop\/files\/B084KHGBQZ.jpg?v=1775812727","width":1200},{"alt":null,"id":41170327535767,"position":2,"preview_image":{"aspect_ratio":0.75,"height":1600,"width":1200,"src":"\/\/newnestshop.com\/cdn\/shop\/files\/71RVipYTlDL.jpg?v=1774073805"},"aspect_ratio":0.75,"height":1600,"media_type":"image","src":"\/\/newnestshop.com\/cdn\/shop\/files\/71RVipYTlDL.jpg?v=1774073805","width":1200},{"alt":null,"id":41170327568535,"position":3,"preview_image":{"aspect_ratio":0.75,"height":1600,"width":1200,"src":"\/\/newnestshop.com\/cdn\/shop\/files\/71-8li3OOeL.jpg?v=1774073805"},"aspect_ratio":0.75,"height":1600,"media_type":"image","src":"\/\/newnestshop.com\/cdn\/shop\/files\/71-8li3OOeL.jpg?v=1774073805","width":1200},{"alt":null,"id":41170327601303,"position":4,"preview_image":{"aspect_ratio":0.75,"height":1600,"width":1200,"src":"\/\/newnestshop.com\/cdn\/shop\/files\/71_ZpCDq5PL.jpg?v=1774073805"},"aspect_ratio":0.75,"height":1600,"media_type":"image","src":"\/\/newnestshop.com\/cdn\/shop\/files\/71_ZpCDq5PL.jpg?v=1774073805","width":1200},{"alt":null,"id":41170327634071,"position":5,"preview_image":{"aspect_ratio":0.75,"height":1600,"width":1200,"src":"\/\/newnestshop.com\/cdn\/shop\/files\/71jFcjydi1L.jpg?v=1774073805"},"aspect_ratio":0.75,"height":1600,"media_type":"image","src":"\/\/newnestshop.com\/cdn\/shop\/files\/71jFcjydi1L.jpg?v=1774073805","width":1200},{"alt":null,"id":41170327666839,"position":6,"preview_image":{"aspect_ratio":0.75,"height":1600,"width":1200,"src":"\/\/newnestshop.com\/cdn\/shop\/files\/714DH-Y0nuL.jpg?v=1774073805"},"aspect_ratio":0.75,"height":1600,"media_type":"image","src":"\/\/newnestshop.com\/cdn\/shop\/files\/714DH-Y0nuL.jpg?v=1774073805","width":1200},{"alt":null,"id":41170327699607,"position":7,"preview_image":{"aspect_ratio":0.75,"height":1600,"width":1200,"src":"\/\/newnestshop.com\/cdn\/shop\/files\/715vCBqfCSL.jpg?v=1774073805"},"aspect_ratio":0.75,"height":1600,"media_type":"image","src":"\/\/newnestshop.com\/cdn\/shop\/files\/715vCBqfCSL.jpg?v=1774073805","width":1200}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eSYSTEM SENSOR 2WT-B 12\/24 VDC, 2-Wire, Thermal, with Base, I3 Series, Detector\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eThe System Sensor 2WT-B is a 2-wire, photoelectric i3 smoke and heat detector.\nSystem Sensor i3 series smoke detectors represent a significant advancement in\nconventional detection.
