IMPORTANT SAFETY REQUIREMENTS BY UL STANDARDS

Prior to installation, the following must be
observed: (per UL 325.56.8.4).
a) Install the gate operator only when:
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 mini-
mum of 4 feet (1.22 m) above the ground to prevent
a 2 1/4 inch (57.2 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.
b) The operator is intended for installation only on gates
used for vehicles. Pedestrians must be supplied with a
separate access opening. The pedestrian access opening
shall be designed to promote pedestrian usage. Locate
the gate such that persons will not come in contact with
the vehicular gate during the entire path of travel of the
vehicular gate.
c) The gate must be installed in a location so that enough
clearance is supplied between the gate and adjacent
structures when opening and closing to reduce the risk
of entrapment. Swinging gates shall not open into public
access areas.
d) The gate must be properly installed and work freely in
both directions prior to the installation of the gate opera-
tor. Do not over-tighten the operator clutch or pressure
relief valve to compensate for a damaged gate.
e) 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 as required by 58.1.6 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.
f) Controls intended for user activation must be located at
least six feet (6') away from any moving part of the gate
and where the user is prevented from reaching over, un-
der, around or through the gate to operate the controls.
Outdoor or easily accessible controls shall have a security
feature to prevent unauthorized use.
g) The stop and/or reset button must be located in the line-
of-sight of the gate. Activation of the reset control shall not
cause the operator to start.
h) A minimum of two (2) WARNING SIGNS shall be in-
stalled, one on each side of the gate where easily visible.
i) For gate operators utilizing a non-contact sensor in ac-
cordance with UL 31.1.1:
1. See instructions on the placement of non-contact
sensors for each Type of application.
2. Care shall be exercised to reduce the risk of nui-
sance 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.
j) For a gate operator utilizing a contact sensor in accor-
dance with 31.1.1:
1. One or more contact sensors shall be located where
the risk of entrapment or obstruction exists, such as at
the leading edge, trailing edge, and postmounted 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 landscap-
ing or similar obstruction. A wireless contact sensor
shall function under the intended end-use conditions.
6. 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 con-
tact sensors shall be located on the bottom edge.
7. One or more contact sensors shall be located at the
bottom edge of a vertical barrier (arm).
