A Guide to Common Loops
The following types of loops are commonly used:
Reversing Loop:
Used to stop or reverse direction of an automatic
gate or barrier operator.
Free Exit (Egress) or Free Entry (Ingress):
Used to open an automatic gate or raise the arm of a
barrier operator.
Shadow Loop:
Used in
swing gate applications. This loop is placed inside the
swing area of the gate, is only active when the gate is
in the full open position, and will not allow the swing
gate to close.
Close Loop:
Used in barrier operator applications. This loop is
placed directly under the arm of the operator. When the
vehicle clears the loop, the arm automatically lowers.
Arming loop:
Used to control access to a site.
The vehicle must drive onto the arming loop before using
an access device such as a transmitter or card. |
