Vehicle Detector Logic Mode Selection
The Detector Logic (DL) menu item, found in the Installer Menu, lets you set the anti-tailgate mode. This menu
item works in conjunction with the Close Timer (CT) when the vehicle detector is triggered. If you plan to use the
anti-tailgate feature, re-check the the Close Timer (CT) setting to make sure it’s compatible.
The two selectable modes for DL are as follows:
Mode 1 (Default): The default setting 1 causes the Close Timer to start when the Center Loop is clear. The Close Timer begins to count
down only after all vehicle detectors are clear and no other open command is present.
Mode 2: A setting of 2 causes the Close Timer to start when the open limit switch trips. The close timer does not wait for vehicle detectors
to clear, but instead it starts running as soon as the open limit is reached.
NOTICE: Using any vehicle detector logic mode other than Mode 1 (default) requires that all the loops be placed
with the geometry and spacing as shown in the layout drawings. See “Reference” on page 7-1.

The Smart DC 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, but HySecurity’s custom HY-5A mini-detector module plugs directly into the Smart DC Controller, making
eld installation much faster and enhancing performance.

common box type detectors:
• Loop frequency is automatically set and monitored by the Smart DC Controller.
• Best operating frequency for each loop is automatically selected.
• Cross-talk between multiple loops is impossible.
• Very low power draw, which is important for maximum UPS capability during a power failure or for solar applications.
• Loop frequency and call strength can be reported on the Smart DC Controller display.
• Loop malfunctions are stored by the Smart DC Controller and appear in code on the display.
NOTE: It is not mandatory to use two separate detectors for inner and outer obstruction detection; however, the
benets of using the additional HY-5A detector are great. Several new features are possible, such as second
vehicle tailgating detection, loitering alert, and selectable non-reversing options.
Four vehicle detector inputs (terminals: EXIT LOOP, IN OBS LOOP, OUT OBS LOOP, CENTER LOOP) exist on the
Smart DC Controller, as well as the four direct plug ins for the HY-5A modules. See “Overview of the SDC and
Power Module” on page 4-2.
