The detection cable runs through a series of these hook assemblies on its way back to the release mechanism, and the fusible link bridges each hook, holding the cable under tension at that point. When heat at that location reaches the fusible link's rated temperature, the link separates, the hook assembly releases, and tension relaxes throughout the cable run, tripping the release mechanism's trip lever.\u003c\/p\u003e\n      \u003cp\u003eThis single-item listing is for one scissor-style hook assembly, sold individually to replace a hook at a specific detector bracket location rather than to outfit an entire system. The fusible link itself must be installed with the hook assembly positioned correctly toward the terminal detector side of the bracket, a detail Ansul's own installation documentation calls out specifically since incorrect positioning can affect how reliably the link separates and releases tension.\u003c\/p\u003e\n    \u003c\/div\u003e\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\u003cspan class=\"accordion-title\"\u003eTechnical Specifications\u003c\/span\u003e\u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\u003cdiv class=\"accordion-content-inner\"\u003e\n      \u003ctable class=\"specs-table\"\u003e\n        \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n        \u003ctbody\u003e\n          \u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eAnsul \/ Pyro-Chem\u003c\/td\u003e\n\u003c\/tr\u003e\n          \u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e435545\u003c\/td\u003e\n\u003c\/tr\u003e\n          \u003ctr\u003e\n\u003ctd\u003eComponent Type\u003c\/td\u003e\n\u003ctd\u003eScissor Style Detector Hook Assembly (Single Item)\u003c\/td\u003e\n\u003c\/tr\u003e\n          \u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eAnsul R-102 and Pyro-Chem Kitchen Fire Suppression Detection Systems\u003c\/td\u003e\n\u003c\/tr\u003e\n          \u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eSupports Fusible Link at Detector Bracket and Releases Cable Tension on Separation\u003c\/td\u003e\n\u003c\/tr\u003e\n          \u003ctr\u003e\n\u003ctd\u003eMounting Location\u003c\/td\u003e\n\u003ctd\u003eDetector Bracket within Duct or Header Opening\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003c\/tbody\u003e\n      \u003c\/table\u003e\n    \u003c\/div\u003e\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\u003cspan class=\"accordion-title\"\u003eInstallation and Compliance\u003c\/span\u003e\u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\u003cdiv class=\"accordion-content-inner\"\u003e\n      \u003cp\u003eKitchen suppression systems are pre-engineered systems under NFPA 17A, and replacing a detector hook assembly must be performed by a certified system distributor along with reinstallation of a properly rated fusible link.\u003c\/p\u003e\n      \u003cul\u003e\n        \u003cli\u003e\n\u003cstrong\u003eSemiannual Professional Service:\u003c\/strong\u003e A qualified technician inspects every detector hook assembly and fusible link in the system at each required service interval, checking for correct positioning, secure mounting, and proper fusible link rating for the protected appliance's temperature exposure.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eMandatory Fusible Link Replacement:\u003c\/strong\u003e The fusible link supported by this hook assembly must be replaced, not just inspected, at every semiannual service interval, since links that appear undamaged may have accumulated thermal stress that alters their rated separation temperature.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eCorrect Positioning Required:\u003c\/strong\u003e The hook assembly with the fusible link in place must be located toward the terminal detector side of its bracket, per Ansul installation specifications, to ensure reliable release tension behavior.\u003c\/li\u003e\n      \u003c\/ul\u003e\n    \u003c\/div\u003e\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\u003cspan class=\"accordion-title\"\u003eFAQ\u003c\/span\u003e\u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\u003cdiv class=\"accordion-content-inner\"\u003e\n      \u003ch3\u003eDoes this come with a fusible link included?\u003c\/h3\u003e\n      \u003cp\u003eThis listing is for the hook assembly itself, sold as a single item.
