Its drift compensation and smoothing algorithms help reduce nuisance alarms associated with dust accumulation and RF interference.\u003cbr\u003e\u003cbr\u003eRed and green LEDs provide clear local status indication during power-up, standby, alarm, maintenance, and freeze trouble conditions. In alarm, the sounder produces an 85 dB temporal tone. Compatible i3 systems can provide remote maintenance signaling and synchronized sounder operation when used with the appropriate modules or panel.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003e• Four-wire, plug-in design; base included\u003cbr\u003e• In-line terminals and Stop-Drop ’N Lock base attachment\u003cbr\u003e• Simplified sensitivity measurement with the SENS-RDR\u003cbr\u003e• Isolated thermal sensor, built-in sounder, and Form C relay","brand":"System Sensor","offers":[{"title":"Default Title","offer_id":68544519962845,"sku":"Kaybee-4WITAR-B","price":221.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/9912\/2909\/files\/4WITAR-B-1_ae219ab8-a0fe-4269-ba3d-23540628b10c.jpg?v=1794590688","url":"https:\/\/kaybeesecurity.com\/products\/system-sensor-4witar-b-i3-series-4-wire-photoelectric-smoke-detector-with-isolated-135-f-heat-sensor-sounder-and-form-c-relay-white-1","provider":"Kaybee Security","version":"1.0","type":"link"}
