Instructions regarding intended installation:
Install the gate operator only if:
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 (1.22 m) above the ground to prevent a 2 ¼ 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.
4. Guarding is supplied for exposed rollers.
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.
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
should not open into public access areas.
The gate must be properly installed and work freely in both directions prior to the installation of the
gate operator. Do not over-tighten the operator clutch, pressure relief valve or reduce reversing
sensitivity to compensate for a damaged gate.
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. A warning 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.
4. No other activation device shall be connected.
Controls intended for user activation must be located at least ten feet (10’) away from any moving
part of the gate and where the user is prevented from reaching over, under, around or through the
gate to operate the controls. Outdoor or easily accessible controls should have a security feature to
prevent unauthorized use.
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.
A minimum of two (2) WARNING SIGNS shall be installed, one on each side of the gate where easily
visible.
For gate operators utilizing a non-contact sensor:
1. See the 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 in the opening direction.
3. One or more non-contact sensors shall be located where the risk of entrapment or
obstruction exist, such as the perimeter reachable by a moving gate or barrier.
