HySecurity recommends that vehicle detectors be used for free exit and obstruction sensing logic only. The
exception is in parking or barrier arm applications where detectors may also be used to close the gate. In
applications employing our swing, vertical lift, or sliding gate operators, closing logic cannot be used except
when the anti-tailgate logic is employed.
Vehicle detector functions (OR IR, HD, DL ) are configurable through the "Installer Menu: Table 2" on page 34.

TailGate Alert

User relay option 11 is available for notification devices. For example, if a vehicle is tailgating, the relay will be
triggered by the tailgating vehicle crossing the loops. A flasher or audio device, connected to the user relay,
would flash or sound and provide notification. Refer to Table 3.

Anti-TailGate Mode Selection

The Detector Logic (DL) menu item, found in the "Installer Menu: Table 2" on page 34, 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, check the time delay aspect of the Close Timer (CL) setting.
The four selectable modes for DL are as follows:
Mode 1 (Default): An input from either the Free Exit, Outside Obstruction Loop, Inside Obstruction Loop, or the
Center Loop will hold the gate open, reset the close timer, and ignore all close inputs. The close timer begins to
count down only after all vehicle detectors are clear and no other open command is present.
Mode 2: The close timer does not wait for vehicle detectors to clear, but instead it starts running as soon as the
open limit is reached.
Mode 3: When both inside and outside obstruction loops are simultaneously active, the gate will close
immediately once all vehicle detectors are no longer triggered (vehicle loops clear) unless another open
command is present.
Mode 4: Full anti-tailgate logic includes Mode 3 functions. In addition, the gate will stop during the opening
cycle when both OOLD & IOLD are tripped simultaneously. When the OOLD & IOLD loops are cleared, the gate
closes immediately. The OOLD & IOLD can be individually set so that, if tripped while closing, the gate may
either, pause only or reverse to reopen. The free exit detector input is ignored while the gate is closing.
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 on page 62 and 63. The detector
Modes 3 and 4 require use of separate inner and outer obstruction detectors and are not available in swing gate
operators.
