Connecting Hy5A Vehicle Detectors - HySecurity StrongArm 14F Programming And Operations Manual

Four vehicle detector inputs (terminals: 8, 10, 11, and 12) exist on the Smart Touch Controller, as well as the
four direct plug ins (FREE EXIT, INSIDE OBSTR, OUTSIDE OBSTR, SHADOW/RESET) for the Hy5A modules.
Refer to Overview of the STC and Power Supply Board on page 76.
The vehicle detector input functions are as follows:
• Free Exit Loop Detector - Opens a fully closed gate.
• Outside Obstruction Loop Detector (Out Obs Loop) - Triggered by the outside (public side) vehicle
detector loop
• Inside Obstruction Loop Detector (In Obs Loop) - Triggered by the inside (secure side) vehicle detector
loop
• Center/Reset/Shadow Loop Detector - On barrier arm gates, prevents closure when active. On swing
gates, prevents gate from opening or closing when the vehicle detector is active.
NOTE: Use of any combination of Hy5A detectors and box detectors is acceptable. On occasion, multiple
obstruction detectors may be mandatory. For example, an area greater than 200 square feet (61 square meters)
of vehicle loop cannot be connected to any one detector because the sensitivity becomes inadequate.

NOTE: For illustrations and detailed instructions, refer to the literature supplied with the Hy5A vehicle detectors. The installation
instructions are also available online at
Install each Hy5A vehicle detector module, one at a time using the following steps:
1. Turn off the AC power switch on the Control Box.
2. Insert the locking end of the two white plastic standoffs into the
mounting holes on the detector.
3. Plug the detector into the appropriate socket along the right
edge of the Smart Touch Controller. Be careful to align the six
detector pins into the socket correctly (the screws for tightening
the terminals should face toward the board), and then snap the
standoffs into the holes in the control box.
4. Route the loop wires through the holes provided in the control
box and connect the loop leads to the two terminals on the
Hy5A detector. Tighten the terminal screws securely.
5. To enable the detector, turn on power. The detector will
immediately tune if it is connected to a vehicle loop. Make
sure no cars or other metal objects are over the loop.
6. Repeat Steps 1 through 5 for each Hy5A detector.
7. If the detector module is unplugged after it is enabled, a communications alert (ALERT 10) will be
triggered. If the fault is not resolved, an error message, ERROR 3 "Detector Failed" is displayed.
NOTE: If there is any detector fault, the gate operator functions as if the detector is triggered.
Pressing the RESET button:
• Clears any errors
• Tunes the detectors on connected loops
• Un-installs any detectors that have been removed
