temperature sensor configured for vertical mounting. Its rate-compensated operating principle responds to surrounding air temperature while maintaining effective response under both gradual and rapidly developing thermal conditions. The detector incorporates a 300-series stainless steel shell and stainless steel hex mounting head, with its internal contact area hermetically sealed from the surrounding environment. The normally-open switching configuration closes at the nominal 190°F threshold and is suitable for initiating alarms or controlling compatible clean-agent, CO2, water, and dry-chemical suppression equipment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e190°F Activation Point: Factory-set to operate at a nominal temperature of 190°F (88°C). \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eClose-on-Rise Operation: Normally-open contacts close when the specified thermal threshold is reached. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eRate-Compensated Detection: Responds to surrounding air temperature while accounting for different rates of temperature increase. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eVertical Mounting: Model 27121-20 is specifically configured for vertical installation. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eStainless Steel Hex Head: Uses a 300-series stainless steel mounting head for durable installation. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eStainless Steel Shell: Incorporates a 300-series stainless steel outer shell with a hermetically sealed contact area. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eTemperature Tolerance: Rated at +7°F\/-8°F relative to the nominal activation temperature. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eSelf-Restoring Design: Provides repeatable thermal operation without requiring replacement after normal testing or activation conditions. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 12-E27121-020-04 delivers the reliability and precision required for temperature-based fire detection and suppression-system initiation.\u003c\/p\u003e","brand":"Kidde-Fenwal","offers":[{"title":"Default Title","offer_id":52254903304490,"sku":"12-E27121-020-04","price":442.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/s-l1600_46f6b54a-b4d6-4fd3-b661-4d64e2d5b637.webp?v=1786596526","url":"https:\/\/iqelectro.com\/products\/kidde-fenwal-12-e27121-020-04-detect-a-fire-190-f-temperature-sensor","provider":"IQElectro","version":"1.0","type":"link"}
