The regulator is the component that controls the flow of nitrogen expellant gas from the cartridge into the agent tank at system actuation, and like Ansul's equivalent R-102 hardware, it is designed to deliver a constant, specified gas flow so the agent discharges at the pressure and rate the system was engineered around.\u003c\/p\u003e\n      \u003cp\u003eBecause the regulator setting directly affects how effectively the agent reaches the nozzles during an actual discharge, rebuilding it is not a routine annual task. It is performed during the system's 12-year maintenance examination, using a dedicated test kit to verify the regulator setting and gas flow afterward, confirming the rebuilt regulator performs to specification before the system is returned to service.\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\u003ePyro-Chem\u003c\/td\u003e\n\u003c\/tr\u003e\n          \u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e551061\u003c\/td\u003e\n\u003c\/tr\u003e\n          \u003ctr\u003e\n\u003ctd\u003eComponent Type\u003c\/td\u003e\n\u003ctd\u003ePressure Regulator Rebuild Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n          \u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003ePyro-Chem Kitchen Fire Suppression Release Mechanism\u003c\/td\u003e\n\u003c\/tr\u003e\n          \u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eRebuilds Regulator Controlling Nitrogen Expellant Flow to Agent Tank\u003c\/td\u003e\n\u003c\/tr\u003e\n          \u003ctr\u003e\n\u003ctd\u003eService Interval\u003c\/td\u003e\n\u003ctd\u003e12-Year Maintenance Examination\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 regulator rebuild work must be performed only by a certified Pyro-Chem distributor as part of the system's mandatory 12-year maintenance examination.\u003c\/p\u003e\n      \u003cul\u003e\n        \u003cli\u003e\n\u003cstrong\u003e12-Year Maintenance Examination:\u003c\/strong\u003e This is the scheduled interval at which the regulator is rebuilt using this kit, alongside the broader teardown and inspection of the release mechanism and agent tank required at this stage of the system's life.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003ePost-Rebuild Verification:\u003c\/strong\u003e After rebuilding the regulator, the technician must use the manufacturer's regulator test kit to verify the regulator delivers gas flow within specification before the system is recharged and returned to service.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eDocumentation:\u003c\/strong\u003e The 12-year examination, including regulator rebuild work, must be documented per NFPA 17A recordkeeping requirements.\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\u003eWhy does the regulator need rebuilding at 12 years specifically?\u003c\/h3\u003e\n      \u003cp\u003eThe 12-year mark is when Pyro-Chem and comparable kitchen suppression systems require a full maintenance examination of the release mechanism and agent tank, including the regulator.
