The Genie 112228.0001.S is a end-of-line resistor pack for use with Genie commercial door operators. Pack of 10 x 2.2K ohm end-of-line resistors for supervised safety loop circuits in commercial door operators. Notable features include: 2.2k ohm (2200 ohm) resistance value for supervised safety loop circuits; pack of 10 resistors for multi-zone or service stock use; enables three-state loop supervision: normal, open, and short fault detection. Compatible with: Genie commercial door operators with supervised safety loops, Access control and gate operator systems requiring end-of-line resistor supervision, Monitored safety edge and loop detector circuits using 2.2K ohm EOL resistors. This is a genuine OEM replacement component for qualified service technicians.
A: EOL (End-of-Line) resistors are placed at the end of a supervised safety circuit. The controller monitors the resistance to detect open circuits (broken wire or triggered device) and short circuits (tamper or fault), providing a three-state supervised loop.
A: 2.2K ohms (2200 ohms) is the specific resistance value required by the supervised loop circuit in compatible Genie operators. Using an incorrect value will cause the controller to read the loop as faulted or unsupervised.
A: The resistor is typically installed in parallel or series with the safety device contacts at the far end of the wiring loop, away from the controller. Refer to the operator wiring diagram for the correct configuration.
A: The pack contains 10 resistors, providing spares for multi-zone installations or future replacements. Resistors are inexpensive and fragile, so having extras on hand is practical for service technicians.
A: A failed or incorrect EOL resistor causes the supervised loop controller to detect a fault condition, which may prevent the operator from running or trigger a fault alarm. Replace with the correct 2.2K ohm value and verify loop supervision restores normal operation.
