Doorking 9409-010 Dual Channel Loop Detector

The DoorKing 9409-010 is a dual-channel plug-in vehicle loop detector for DoorKing gate operators. It plugs into the loop detector port on the operator control board. Loop 1 feeds the control board directly and loop 2 switches a dry contact relay. Self-tuning circuitry tracks loop drift and weather changes. Four frequency and four sensitivity settings. Sensitivity boost raises sensitivity once a vehicle is detected so high-bed vehicles are not lost. Fast-Trak, a loop fault monitor with a flashing LED, a frequency readout on the LED at power-up, and a reset button. Before You Order DoorKing lists the 9409, 9410 and 9411 plug-in detectors for its legacy operators. Check the operator manual for the correct detector. Loop not included.

Set nearby loops to different frequencies. Low-power version for solar operators: 9415-010. Family: 9410-010 single channel, 9409-010 dual channel, 9411-010 single channel with aux relay.
