2.7 Loop Detector Wiring
Loop detectors must be installed to prevent the gate from accidentally closing on vehicles that may be in the path of the gate.
• Install 9410-101 Single Channel or 9409-101 Dual Channel DoorKing plug-in loop detectors (Sold separately).
• If using external loop detectors, use only UL listed (or equivalent) detectors. Use a separate power supply for
external loop detectors. Inputs to circuit board are Normally Open (NO).
• Disconnect power to gate operator before installing any loop detectors.

Reverse Loop
• Loop layout shown is for a typical overhead gate application
with two-way traffic, or one-way exit only traffic.
• Refer to the Loop Information Manual (available from
www.dkaccess.com) for more information on loops and
loop detectors.
Automatic exit loop
lead in wires are
twisted approx. 6
twists per foot.
Reverse loop lead in wires are twisted approx.
6 twists per foot and are wired in series.
