{"product_id":"liftmaster-lmeolres-10","title":"LiftMaster LMEOLRES-10 End-of-Line Resistor — 10 kΩ","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster LMEOLRES-10 is a 10-kilohm end-of-line resistor identified in the LM21XP release-device accessory information. It belongs to a specified supervised circuit and must be installed only in the arrangement required by the exact system documentation. This is an electrical termination component, not a smoke detector, release device or complete alarm interface. Match the required resistance and application before ordering; a resistor with the wrong value or installed in the wrong location can prevent the system from supervising the intended field wiring correctly.\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\u003eLM21XP arrangements specifying LMEOLRES-10\u003c\/td\u003e\n\u003ctd\u003eFollow the exact release-device and detector circuit documentation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther supervised inputs\u003c\/td\u003e\n\u003ctd\u003eUse only where their instructions call for this specific resistor.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2.2 kΩ or other resistor values\u003c\/td\u003e\n\u003ctd\u003eDifferent electrical selections; not interchangeable with 10 kΩ.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnd-of-line relays\u003c\/td\u003e\n\u003ctd\u003eDifferent components and functions; a resistor is not a relay substitute.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGate safety-edge inputs\u003c\/td\u003e\n\u003ctd\u003eNo universal compatibility based on resistance alone.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003ePreserve the Intended Circuit Supervision\u003c\/h2\u003e\u003cp\u003eAn end-of-line component is part of the circuit design, not simply a way to remove a trouble indication. Have qualified personnel identify why the circuit reports a fault before choosing a replacement. Open wiring, loose connections, damaged devices or incorrect configuration may be the actual cause. Installing a resistor without resolving those conditions can leave the system unable to perform its intended function.\u003c\/p\u003e\u003cp\u003eUse the manufacturer diagram to determine the correct circuit location and connection arrangement. Do not move the resistor to a convenient control terminal merely to make a fault disappear. Document the existing wiring before service, confirm the connected detector and release-device configuration, and perform the prescribed functional and fault-supervision tests after the repair. A matching resistance value does not establish approval for every fire-door or access-control circuit.\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\u003ePart number\u003c\/td\u003e\n\u003ctd\u003eLMEOLRES-10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent\u003c\/td\u003e\n\u003ctd\u003eEnd-of-line resistor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResistance\u003c\/td\u003e\n\u003ctd\u003e10 kΩ \/ 10,000 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDocumented example\u003c\/td\u003e\n\u003ctd\u003eLM21XP release-device accessory guide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeparate items\u003c\/td\u003e\n\u003ctd\u003eDetectors, release device and interface relays\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSelection basis\u003c\/td\u003e\n\u003ctd\u003eExact supervised-circuit diagram and approved accessory list\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\u003eRecord the release-device model and exact circuit being serviced.\u003c\/li\u003e\n\u003cli\u003eConfirm the specified 10 kΩ value and LMEOLRES-10 reference.\u003c\/li\u003e\n\u003cli\u003eInspect field wiring and connected devices for the cause of the fault.\u003c\/li\u003e\n\u003cli\u003eArrange the required post-service release and supervision tests.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThis offer identifies the end-of-line resistor.
