Frequency:
Knowing the exact frequency of a loop can
be useful as a diagnostic tool, and verifying
the stability of the loop frequency is valuable
information. To view the actual loop frequency
of a specic vehicle detector, go to the setting
for that detector in the Installer Menu, switch
the selection from 0 to 1, and press the Select
button. The display will show the loop frequency.
The frequency is usually between 20,000 to 80,000
Hertz.
Changing the Loop Frequency:
Hy5B detectors can never crosstalk. If for any
reason, you want to manually change the loop
frequency, change the Installer Menu option
for the desired loop from 0 to 3, and then press
the Select button. Each detector has a choice of
four frequencies. Press the Select button when
the desired frequency setting is found, and the
controller will perform a reset and tune to the new
frequency setting.
Call Strength Level:
Knowing the call strength of a detector is valuable
because it provides information about how well
the loop is actually “seeing” a specic 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 0 to 7.
As indicated in the table below, when the Installer
Menu setting for a given detector is set to 2, and
the Menu button is pressed, the LCD display will
read Level 0 - 7 Call Level. If the call strength on
the display appears as a level 4 or less, consider
increasing the sensitivity level by adjusting the
rotary switch on the Hy5B detector.
