DKS 6002 - 2.8 Loop Detector and Loop Wiring

2.8 Loop Detector and Loop Wiring
• Loops and loop detectors are required to provide protection to vehicular traffic through the
gate system.
• Loop detector wiring is shown for DoorKing model 9405 and 9406 Plug-In loop detectors
only. If other loop detectors are used, refer to the installation instructions supplied with those
detectors for wiring requirements.
• If other loop detectors are used, all inputs to the terminal strip are NORMALLY OPEN. Use a
separate power supply to power external detectors. Be sure that power is turned off prior to
making any connections to the terminal strip.
• Loop layout shown is for a typical swing gate application with two-way traffic or one-way exit
only traffic. For one-way entry only traffic, the open loop is replaced with a second reverse
loop wired in series with the first reverse loop. The 9506 detector is not needed in this
application.
• Refer to the separate Loop Information Manual (available from DoorKing) for instructions on
installing loops or preformed loops.
• For correct SHADOW LOOP operation, jumper wire must be placed from terminal 9 to
terminal 10. SW1 switch 5 must be OFF, SW2 switch 1 must be ON and SW2 switch 2 must
be OFF.
• NOTE: Output of Shadow Loop Detector may be connected directly to terminals 8 and 9
(dotted line - no jumper required between 9 and 10) if SW 1, switch 5 is ON. However, with
this switch ON, terminal 8 becomes a shadow input (active only when the gate is FULL
OPEN) and all reversing devices connected to terminal 8 will operate as shadow
devices. If this is not desirable, wire the shadow loop detector as instructed in the above.

Shadow loop will only hold the gate in the open position when a vehicle is present. Shadow
loop WILL NOT reverse the gate during the close cycle.

Solid line shows connection with terminal 8 setup as a standard reverse input (SW1, Sw 5 OFF). If
terminal 8 is setup as a shadow reverse input (SW1, Sw 5 ON), output of loop detector can be
connected directly to terminals 8, 9 and no jumper between 9, 10.
