Vehicle Detectors and the Smart Touch Controller
The Smart Touch Controller provides an interface for up to four different vehicle detector functions.
NOTE: Standard box type 11 pin (24 VDC or 24 VAC) vehicle detectors may be connected in the traditional manner to the controller,
but HySecurity Hy5B mini-detector modules plug directly into the board, making eld installation much faster and enhancing
performance.
The Hy5B detector communicates with the Smart Touch Controller microprocessor to achieve the following
benets:
• Automatic Sensitivity – The Hy5B monitors vehicle trafc over the loop and automatically adjusts the loop sensitivity based on
vehicle type and volume.
• Automatic Gate Compensation – The Hy5B discerns gate travel over the loop and automatically compensates for its effect. The
compensation allows the Hy5B to operate with a higher sensitivity which provides better detection capability.
• No Loop Crosstalk – Exclusive use of Hy5B vehicle detectors in HySecurity gate operators, completely eliminates crosstalk and the
need to set frequency levels.
• Vehicle Counting – Hy5B detects passenger vehicles and motorcycles.
• Automatic Lightning Suppression - Where lightning strikes occur often, connecting to the ground terminal minimizes the chance
of activation or lock-up.
• Health Scores for Loop – Hy5B monitors the loop for changes that are indicative of possible problems. A score is accessible
through the event log, LG menu item.
• Automatic Hy5A emulation mode for backward compatibility.
Hy5B Installation
To install an Hy5B vehicle detector, you will need to take
the following steps:
• Test the vehicle loop
• To use all the features of Hy5B, update the software version
on the gate operator to the latest version using S.T.A.R.T.
and a PC laptop. Access free software updates from the
HySecurity website: www.hysecurity.com
• Install the Hy5B vehicle detector
• Fully cycle the gate at least 2 times to allow the detector to
adjust to the effects of the gate during travel. Drive a test
vehicle over the loops.
Test the Vehicle Loop
Run diagnostic tests on the vehicle loops before
installing Hy5B vehicle detectors to ensure the loops
are in good working condition. The following tests
cannot guarantee a functioning loop, but failure of
either test means that the loop may be damaged or
need to be replaced.
1. Test – Measure the resistance of the loop and
lead-in wire. It should not exceed 4.0 ohms.
2. Test – Measure the resistance to earth ground with a Megohmeter (Megger). It should be 100 Megohms
or more. Below 50 mega-ohms, install a new loop.
NOTE: Loops may function at 100 Megohms or less, but will not be reliable (for example, when the ground is wet from rainfall). A low
megohm reading on the resistance to earth ground usually occurs due to broken or moisture saturated insulation. Be sure to use wire
with a direct burial jacket such as XLPE or XHHW wire. Do NOT use THHN wire.
