While bulk packs are optimized for full-facility overhauls, the 551059-P001 is the strategic choice for precision field service and emergency go-bag inventory. This individual 16-gram cartridge provides the stored kinetic energy required to actuate a single agent cylinder. Upon a manual pull or a thermal link melting, the system's firing pin punctures the hermetic seal, releasing high-pressure gas to drive the fire suppressant through the discharge manifold.\u003c\/p\u003e\n        \u003cp\u003eFor facility managers overseeing small-scale kitchen infrastructure such as small cafes, food trucks, or dedicated server closets, this individual format ensures exact inventory control. It allows for post-incident system restoration following a localized hazard suppression event or a functional test without the overhead of surplus stock. By maintaining a single 551059-P001 on-site, technicians can perform a spot replacement, ensuring the facility's fire defense remains active with the exact OEM tolerances required for a full-volume discharge.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 2: Technical Specifications --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eTechnical Specifications\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003ctable class=\"specs-table\"\u003e\n          \u003cthead\u003e\n            \u003ctr\u003e\n              \u003cth\u003eFeature\u003c\/th\u003e\n              \u003cth\u003eDetails\u003c\/th\u003e\n            \u003c\/tr\u003e\n          \u003c\/thead\u003e\n          \u003ctbody\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eManufacturer\u003c\/td\u003e\n              \u003ctd\u003ePyro-Chem (A Johnson Controls Brand)\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003ePart Number\u003c\/td\u003e\n              \u003ctd\u003e551059-P001 (Single Item)\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eAgent Type\u003c\/td\u003e\n              \u003ctd\u003eCarbon Dioxide (CO2)\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eCharge Weight\u003c\/td\u003e\n              \u003ctd\u003e16 Grams\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eCompatibility\u003c\/td\u003e\n              \u003ctd\u003eKitchen Knight II and Monarch Systems\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eActuation Method\u003c\/td\u003e\n              \u003ctd\u003eFiring Pin Puncture Interface\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eWeight Tolerance\u003c\/td\u003e\n              \u003ctd\u003eReplace if more than 1\/4 oz below stamped gross weight\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eCertifications\u003c\/td\u003e\n              \u003ctd\u003eUL Listed, FM Approved\u003c\/td\u003e\n            \u003c\/tr\u003e\n          \u003c\/tbody\u003e\n        \u003c\/table\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 3: Installation \u0026 Compliance --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eInstallation \u0026amp; Compliance\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003cp\u003eThe 551059-P001 must be installed by a certified fire suppression technician in accordance with the Kitchen Knight II or Monarch system design manual and NFPA 17A.

Every individual cartridge must undergo a gross weight verification during its semi-annual inspection.
