{"product_id":"liftmaster-k79-13493-2","title":"LiftMaster K79-13493-2 FDCL Logic Board Replacement Kit — Verify 06-FDCL-500 Charge Circuit","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster K79-13493-2 is the FDCL logic-board replacement kit described in the dedicated manufacturer instruction sheet. Its application requirements specify an FDCL operator with a charge circuit board incorporating firmware version 06-FDCL-500. Confirm that exact requirement and the complete operator electrical configuration before ordering. This is not a universal replacement across similarly numbered FDC, FDCL or FDO fire-door control boards. Select the replacement by the complete part number and the installed equipment configuration. A similar photograph or a shared LiftMaster brand name does not establish interchangeability. Confirm the applicable service drawing before ordering so the repair addresses the correct component and its related mounting, connection and operating requirements.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eCompatibility — Models, Versions and Exclusions\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel or selection point\u003c\/th\u003e\n\u003cth\u003eCompatibility requirement\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFDCL with required charge circuit\u003c\/td\u003e\n\u003ctd\u003eVerify the dedicated application requirement before selection.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther firmware or charge boards\u003c\/td\u003e\n\u003ctd\u003eObtain an explicit current manufacturer service recommendation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSingle \/ three phase\u003c\/td\u003e\n\u003ctd\u003eUse the correct equipment-specific wiring procedure.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSimilar FDC \/ FDO references\u003c\/td\u003e\n\u003ctd\u003eNo cross-family interchangeability is established.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eIdentify the Assembly and Plan the Repair\u003c\/h2\u003e\u003cp\u003eThe charge-board firmware condition is a purchasing requirement, not a general label that can be ignored when boards look alike.

Have the fire-door service provider confirm the current replacement recommendation and whether any separate updates or components are required.\u003c\/p\u003e\u003cp\u003eThe instruction sheet requires isolation of both AC supply and the battery connection and provides different wiring arrangements by phase. Keep the required release, supervision and control functions intact. After replacement, qualified personnel must restore the documented settings and complete the applicable fire-door and operator tests; power-up alone does not establish a completed fire-door repair.\u003c\/p\u003e\u003cp\u003eAn electrical symptom does not identify the failed component by itself. Have qualified service personnel inspect the supply, wiring, connections and equipment condition before replacing parts. Record existing labels and terminal references with power safely isolated. A replacement should restore the documented circuit arrangement; it should not be used to change operating voltage, defeat a protective function or compensate for a mechanical load that the equipment cannot safely move.\u003c\/p\u003e\u003ch2\u003eSpecifications and Product Identification\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrdering reference\u003c\/td\u003e\n\u003ctd\u003eK79-13493-2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent\u003c\/td\u003e\n\u003ctd\u003eFDCL logic-board replacement kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRequired platform\u003c\/td\u003e\n\u003ctd\u003eFDCL operator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstruction-sheet requirement\u003c\/td\u003e\n\u003ctd\u003eCharge circuit firmware 06-FDCL-500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWiring distinction\u003c\/td\u003e\n\u003ctd\u003eSeparate single-phase and three-phase instructions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eBefore Ordering\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIdentify the complete FDCL operator and electrical configuration.\u003c\/li\u003e\n\u003cli\u003eVerify the required charge-board firmware reference.\u003c\/li\u003e\n\u003cli\u003eCompare the exact board service suffix and current kit.\u003c\/li\u003e\n\u003cli\u003ePlan AC\/battery isolation and prescribed fire-door functional testing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThis offer identifies the logic-board replacement kit.
