VEHICLE DETECTOR
HySecurity recommends that vehicle detectors
be used for free exit and obstruction sensing
logic only. The exception is in parking or gate
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 "Table 12. Smart DC
Controller - Installer Menu Functions" on page
ANTI-TAILGATE MODE CLOSING LOGIC
The Detector Logic (DL) installer menu item 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 antitailgate 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 counting
down 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 (unless another open command is
present) once all vehicle detectors are no longer
sensing active loops (i.e. vehicle loops are clear).
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 loop layout drawings. The
detector Modes 3 and 4 require use of separate
inner and outer obstruction detectors. Mode 4
is not available in HydraWedge SM50 or gate
operators functioning with HydraSupply XL.
