If HySecurity HY-5A mini detector modules are used, the Smart Touch Controller has ability to store and report detector
and loop fault information for performance diagnostics. If The Smart Touch Controller senses a loop or detector problem,
the LCD display will flash the abbreviation for the affected detector (ELd – ioLd – ooLd – SLd) then it will flash the
appropriate Alert Code (ALE_) to disclose the nature of the problem and the buzzer will chirp.
Loop detector freq change alert
Loop shorted or open alert
Loop detector failed alert
Loop detector active >5 minutes
Loop detector comm. alert
Loop detector function alert
Loop detector failed
Even if the loop problem self heals, historical data about detector/loop performance and a log of Alerts, Faults and Errors
can be retrieved from the Smart Touch Controller by downloading from the RS232 communications port. Optional
HySecurity "START" software, a PC computer, and a special download cable are required to retrieve and read this data
(see bottom of page 31).
Frequency:
Knowing the exact frequency of a loop can be useful as a diagnostic tool, and verifying that the loop frequency is stable is
also very valuable information. To view the actual loop frequency of a specific vehicle detector, go to the setting for that
detector, then switch the selection to 1 and press the PROGRAM button. The display will flash between [F_xx] which are
the high digits, then the low digits of the loop frequency counter. For example: [F_05] + [3413] would represent a
frequency of 53,413 Hertz. The highest digit will probably be only a single digit because loop frequency is usually a five-
digit number, between 20,000 to 80,000 Hertz.
Changing the Loop Frequency:
HY-5A detectors can never crosstalk. If for any reason, you want to manually change the loop frequency, change the
menu selection to a flashing 4 and then press the SELECT button. Each detector has a choice of four frequencies. To
exit, press the PROGRAM button and the controller will perform a reset and tune to the new frequency setting.
Call Strength Level:
Knowing the strength level of a detector call is valuable because it provides information about how well the loop is actually
"seeing" a specific vehicle. For example, it may be useful to check to see if the loop is easily detecting the middle of a
high bed semi-truck. The strength of a detector call can be displayed in real time, on a scale of 1-7. As indicated in the
table below, when a detector's menu setting is set to 2, and the PROGRAM button is pressed, the LCD display will read
[LE_x]. If the call strength is level 4 or less, consider increasing the sensitivity level, by adjusting the rotary switch on the
HY-5A detector.
