System Sensor i3 series smoke detectors represent a significant advancement in conventional detection. The i3 family is founded on three principles: installation ease, intelligence, and instant inspection. The i3 line redefines installation ease with its plug-in design. This allows an installer to pre-wire bases (included with heads). The large wire entry port and in-line terminals provide ample room for neatly routing the wiring inside the base. The base accommodates a variety of back box mounting methods as well as direct mounting with drywall anchors.\u003c\/div\u003e\n\u003cdiv class=\"sc-bczRLJ iwaCMW\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"sc-bczRLJ iwaCMW\"\u003eTo complete the installation, i3 heads plug into the base with a simple Stop-Drop ‘N Lock action. i3 detectors offer a number of intelligent features to simplify testing and maintenance. Drift compensation and smoothing algorithms are standard with the i3 line to minimize nuisance alarms. 2-wire i3 detectors can generate a remote LED indicated maintenance signal when connected to the 2W-MOD2 loop test\/maintenance module or a panel equipped with the i3 protocol. \u003c\/div\u003e\n\u003cdiv class=\"sc-bczRLJ iwaCMW\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"sc-bczRLJ iwaCMW\"\u003eThe SENS-RDR, a wireless device, displays the sensitivity of i3 detectors in terms of percent-per-foot obscuration. The i3 series provides wide-angle red and green LED indicators for instant inspection of the detector’s condition: normal standby, out-of-sensitivity, alarm, or freeze trouble. When connected to the 2W-MOD2 loop test\/maintenance module or a panel with the i3 protocol, the EZ Walk loop test feature is available on 2-wire i3 detectors. This feature verifies the initiating loop wiring by providing LED status indication at each detector.\u003c\/div\u003e\n\u003ch3 class=\"TypographyStyle--11lquxl bMPEkV titleText\" data-test-selector=\"OverviewTitle\"\u003e\u003c\/h3\u003e\n\u003ch3 class=\"TypographyStyle--11lquxl bMPEkV titleText\" data-test-selector=\"OverviewTitle\"\u003eMain Features\u003c\/h3\u003e\n\u003cdiv class=\"sc-bczRLJ iKBAtS\"\u003e\n\u003cul class=\"mainfeatureslist\"\u003e\n\u003cli\u003ePlug-in detector line, mounting base included\u003c\/li\u003e\n\u003cli\u003eLargeWire entry port\u003c\/li\u003e\n\u003cli\u003eIn-line terminals with SEMS screws\u003c\/li\u003e\n\u003cli\u003eMounts to octagonal and single-gang back boxes, 4-square back boxes, or direct to ceiling\u003c\/li\u003e\n\u003cli\u003eStop-Drop ’N Lock attachment to base\u003c\/li\u003e\n\u003cli\u003eRemovable detector cover and chamber\u003c\/li\u003e\n\u003cli\u003eBuilt-in remote maintenance signaling\u003c\/li\u003e\n\u003cli\u003eDrift compensation and smoothing algorithms\u003c\/li\u003e\n\u003cli\u003eSimplified sensitivity measurement\u003c\/li\u003e\n\u003cli\u003eWide-angle, dual-color LED indication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"System Sensor","offers":[{"title":"Default Title","offer_id":43247294021697,"sku":"BK-2WTB","price":52.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/2465\/9009\/files\/66393866-bk-2wtb.png?v=1770772395","url":"https:\/\/www.fireandsafetyplus.com\/products\/system-sensor-2wt-b-photoelectric-i3-series-smoke-detector-2-wire-135f-fixed-thermal-sensor-white","provider":"Fire and Safety Plus","version":"1.0","type":"link"}
