• A minimum of two (2) warning signs shall be installed, one on each side of the gate that is easily
visible.
• The gate must have sufficient room when opening and closing. The gate must be properly installed
and move freely in both directions.
•
Inspect your gate to confirm
: 1) The operator is appropriate for the construction of the gate
and the
usage class of the gate, 2) All openings of a horizontal slide gate are guarded or screened
from the
bottom of the gate to a minimum of 4 feet (1.2 m) above the ground to prevent a 2-1/4
inch (57.15
mm) diameter sphere from passing through the openings anywhere in the gate, and in
that portion of
the adjacent fence that the gate covers in the open position, 3) All exposed pinch
points are
eliminated or guarded, and 4) Guarding is supplied for exposed rollers.
• For gate operators utilizing Type D protection: 1) The gate operator controls must be placed so that
the user has full view of the gate area when the gate is moving, 2) The placard shall be placed
adjacent to the controls, 3) An automatic closing device (such as a timer, loop sensor, or similar
device) shall not be employed, and 4) No other activation device shall be connected.
• The gate operator is intended for installation only on vehicular gates. Pedestrians must access a
separate entrance. The pedestrian entrance shall be designed for pedestrian usage. The gate must be
installed in a location so that pedestrians will not come in contact with the vehicular gate during the
entire path of travel of the vehicular gate.
• For gate operators utilizing a non-contact sensor, see instructions on the placement of non-contact
sensors for each Type of application, 2) 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, and 3) 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.
• For a gate operator utilizing a contact sensor, one or more contact sensors shall be located at the
leading edge, trailing edge, and post mounted both inside and outside of a vehicular horizontal slide
gate. 2) One or more contact sensors shall be located at the bottom edge of a vehicular vertical lift
gate. 3) One or more contact sensors shall be located at the pinch point of a vehicular vertical pivot
gate. 4) 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.
5)
A wireless contact sensor such as 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.
