See instructions on the placement of non-contact sensor for each type of
application.
Care shall be exercised to reduce the risk of nuisance tripping, such as when
a vehicle trips the sensor while the gate is still moving.
One or more non-contact sensors shall be located where the risk of
entrapment or obstruction exists, such as the perimeter reachable by a
moving gate or barrier.
A hardwired contact sensor shall be located and its wiring arranged so that
the communication between the sensor and the gate operator is not
subjected to mechanical damage.
A wireless contact sensor such as the one that transmits radio frequency
(RF) signals to the gate operator for entrapment protection functions shall be
located where the transmission of the signals are not obstructed or impeded
by building structures, natural landscaping or similar obstruction. A wireless
contact sensor shall function under the intended end-use conditions.
One or more contact sensors shall be located on the inside and outside
leading edge of a swing gate. Additionally, if the bottom edge of a swing gate
is greater than 6 inches (152 mm) above the ground at any point in its arc of
travel, one or more contact sensors shall be located on the bottom edge.
