The LiftMaster LMEOLRES-2-2 RESISTOR, 2.2K OHM is a genuine end-of-line (EOL) resistor used to properly terminate and supervise monitored safety circuits on select LiftMaster commercial door and gate operators and accessories. By providing a fixed 2.2K ohm load at the end of a monitored input, it allows the control board to differentiate normal conditions from wiring faults such as opens or shorts, supporting UL 325–compliant monitored safety inputs. It’s commonly used as a replacement part when installing or servicing monitored wired safety edges, photo eyes, or control interfaces that specifically call for a 2.2K ohm EOL resistor.
Installation is straightforward: connect the LMEOLRES-2-2 across the designated EOL or sensor input terminals at the end of the supervised wiring run, following the wiring diagram in the operator or accessory manual; polarity is not required for a resistor. Use only where the documentation specifies a 2.2K ohm EOL—using the wrong value can trigger a constant fault or prevent operation. Compatibility depends on the operator model and firmware; typical applications include select industrial and commercial door operators and vehicular gate operators that support monitored resistive edge or photoelectric inputs. This component is not a safety sensor and does not provide entrapment protection by itself; it must be used with approved monitored devices and tested after installation by a qualified technician.
