Its sensing element consists of a sealed hollow brass chamber with no moving internal parts, surrounded by a protective steel cage and mounting structure. When temperature rises rapidly during a fire condition, expanding air inside the detector creates pressure that is transmitted through copper tubing to the pneumatic control head, initiating system actuation. The pneumatic detection arrangement is vented so that normal gradual changes in ambient temperature do not cause unintended system activation.\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\n\u003cli\u003ePneumatic Heat Detection: Responds to rapid temperature rise by generating increased pneumatic pressure.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eNo Moving Sensing Parts: Uses a sealed hollow brass sensing chamber without mechanical moving components. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e1\/8-Inch Tubing Connection: Interfaces with the system actuation circuit through 1\/8-inch pneumatic tubing.\u003c\/li\u003e\n\u003cli\u003ePneumatic Control Head Interface: Transmits pressure changes to compatible control heads for suppression system actuation.\u003c\/li\u003e\n\u003cli\u003eAmbient Temperature Compensation: Vented system architecture helps prevent gradual environmental temperature changes from initiating discharge. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eSteel Protective Construction: Features steel cages, chambers, and mounting bracket components with a red painted finish. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eIndustrial Configuration: Specifically identified by Kidde-Fenwal as an industrial pneumatic heat detector.\u003c\/li\u003e\n\u003cli\u003eIntegrated Tubing Union: Manufacturer documentation shows a 1\/8-inch tubing union supplied with the detector. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe WK-840845-000 delivers the reliability and precision required for pneumatic heat detection and actuation of compatible industrial fire suppression systems.\u003c\/p\u003e","brand":"Kidde-Fenwal","offers":[{"title":"Default Title","offer_id":52253161029930,"sku":"WK-840845-000","price":499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/s-l1600_0c417ef3-1a66-4d2d-8f76-7a9d9091d6fc.webp?v=1786565743","url":"https:\/\/iqelectro.com\/products\/kidde-fenwal-wk-840845-000-industrial-pneumatic-heat-detector-1-8-inch-tubing","provider":"IQElectro","version":"1.0","type":"link"}
