5.1.5. Free-exit Opening

The Free-exit Opening allows
visitors to exit townhouses,
estates, factories or office parks
easily.
An inductive ground loop is
mounted under the driveway
inside the property a short
distance away from the gate. The
output of the inductive ground
loop detector is connected to the
free-exit input on the controller.
When a vehicle drives over the
loop, a detector senses the metal
in the vehicle and activates the
free-exit function which opens the
gate. The ground loop cannot be
activated by a person or any non-
metallic objects and can be set to
only activate if it detects a large
amount of metal.
Free-exit never initiates a closing
cycle so the Autoclose function
(page 11) must be enabled in
order for the gate to close.
If the gate is already open or opening, triggering the free-exit input will
have no effect other than to reset the Autoclose timer. If the gate is closing,
triggering the free-exit input will immediately stop and re-open the gate.
An infrared beam can be used instead of an inductive ground loop, but the
beam will be activated if a person (or any object) moves through it, so this
option is typically less secure.
Please contact Centurion Systems (Pty) Ltd for more information on
whether a ground loop or infrared beam is better suited to your needs.
