There are four vehicle detector inputs available on the Smart DC Controller as well as via the direct plug in
modules. The vehicle detector input functions are as follows:
• Free Exit Loop Detector - This opens a fully closed gate.
• Outside Obstruction Loop Detector (Out Obs Loop) - This is for the outside reversing loop
• Inside Obstruction Loop Detector (In Obs Loop) - This is for the inside reversing loop
• Center Loop Detector - This is also known as a Shadow Loop and is used for swing gates only to prevent a
gate from starting open or closed when a vehicle is in the path of the gate.
NOTE
Use of any combination of HY-5A detectors and box detectors is acceptable. On occasion, mul-
tiple obstruction detectors may be mandatory. For example, an area greater than 200 square feet
(61 square meters) of loop cannot be connected to any one detector because the sensitivity
becomes inadequate.

ONNECTING
Install the HY-5A Vehicle Detector modules according to the following procedure;
1. Turn off both AC and DC power switches.
2. Insert the locking end of the two white plastic standoffs into the mounting holes on the detector.
CAUTION
During performance of the next step, carefully align the six detector pins into the socket. Failure
to comply may damage the mating connectors.
