To reduce the likelihood of nuisance alarms, all i3 detectors are equipped with both drift compensation and smoothing algorithms. These capabilities minimize both short- and long-term causes of nuisance alarms, such as RF interference and dust accumulation. When connected to the 2W-MOD2 loop test\/ maintenance module or an i3 Ready™ panel, 2-wire i3 detectors can generate a remote maintenance signal when in a maintenance or freeze trouble condition.\u003c\/p\u003e\n\u003cp\u003eTo measure the sensitivity of any i3 detector, the SENS-RDR displays the reading, in terms of percent-per-foot obscuration, within seconds. i3 has red and green LEDs to simplify local status indication during power-up, standby, alarm, maintenance, and freeze trouble conditions. When in alarm, i3 sounder models generate an 85 dB temporal tone. If connected to the RRS-MOD reversing relay\/synchronization module, all i3 sounders on the loop will activate when one detector is in alarm. The RRS-MOD also synchronizes i3 sounder output to ensure a clear audible signal\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eMain Features\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e85 dB sounder\u003c\/li\u003e\n\u003cli\u003eForm C relay\u003c\/li\u003e\n\u003cli\u003eIsolated thermal sensor\u003c\/li\u003e\n\u003cli\u003ePlug-in design (base included)\u003c\/li\u003e\n\u003cli\u003eIn-line terminals\u003c\/li\u003e\n\u003cli\u003eFlexible mounting options\u003c\/li\u003e\n\u003cli\u003eStop-Drop ’N Lock™ attachment to the base\u003c\/li\u003e\n\u003cli\u003eRemovable cover and chamber\u003c\/li\u003e\n\u003cli\u003eRemote 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\u003eDual-color LEDs\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"System Sensor","offers":[{"title":"Default Title","offer_id":43247309127745,"sku":"BK-4WITARB","price":95.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/2465\/9009\/files\/c51c4c6a-1029984286_lg.jpg?v=1770769506","url":"https:\/\/www.fireandsafetyplus.com\/products\/system-sensor-4witar-b-4-wire-photoelectric-i3-smoke-detector-with-isolated-thermal-sensor-built-in-sounder-form-c-relay","provider":"Fire and Safety Plus","version":"1.0","type":"link"}
