SAFETY
» SAFETY INSTALLATION INFORMATION
1. READ and FOLLOW all instructions.
2. The gate operator is intended for use with Class I vehicular swing gates.
Class I denotes a vehicular gate operator (or system) intended for use in a
home of one to four single family dwellings, or a garage or parking area
associated therewith.
Install the gate operator only when the operator is appropriate for the
construction and the usage class of the gate.
3. Gate operating system designers, installers and users must take into account
the possible hazards associated with each individual application. Improperly
designed, installed or maintained systems can create risks for the user as well
as the bystander. Gate system design and installation must reduce public
exposure to potential hazards. Install the gate operator only when the
operator is appropriate for the construction of the gate and the usage class of
the gate. All exposed pinch points must be eliminated or guarded.
4. A gate operator can create high levels of force during normal operation.
Therefore, safety features must be incorporated into every installation.
Specific safety features include photoelectric sensors.
5. The gate must be properly installed and work freely in both directions prior to
the installation of the gate operator.
6. The gate must be installed in a location so that enough clearance is provided
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.
7. The operator is intended for use 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. The pedestrian access
shall be located such that persons will not come in contact with the moving
vehicular gate.
8. Pedestrians should never cross the pathway of a moving gate. The gate
operator is not acceptable for use on any pedestrian gate. Pedestrians must be
supplied with a separate pedestrian access.
9. For an installation utilizing non-contact sensors (photoelectric sensors), see
product manual on the placement of non-contact sensors (photoelectric
sensors) for each type of application.
a. Care shall be exercised to reduce the risk of nuisance tripping, such as when
a vehicle trips the photoelectric sensor while the gate is still moving.
b. One or more non-contact sensors (photoelectric sensors) shall be located
where the risk of entrapment or obstruction exists, such as the perimeter
reachable by a moving gate or barrier.
10. For a gate operator utilizing a contact sensor such as an edge sensor:
a. A hard wired contact sensor shall be located and its wiring arranged so the
communication between the sensor and the gate operator is not subject to
mechanical damage.
b. 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.
11. Never mount any device that operates the gate operator where the user can
reach over, under, around or through the gate to operate the controls.
Controls are to be placed at least 6 feet (1.8 m) from any part of the moving
gate:
• A hard wired control device shall be located and its wiring arranged so that
communication between the control device and the gate operator is not
subject to mechanical damage.
12. Controls intended to be used to reset an operator after 2 sequential activations
of the entrapment protection device or devices must be located in the line of
sight of the gate, or easily accessible controls shall have a security feature to
prevent unauthorized use. Never allow anyone to hang on or ride the gate
during the entire travel of the gate.
13. Each gate operator is provided with two safety warning placards. The placards
are to be installed on the front and back of the gate where they are plainly
visible. The placards may be mounted using cable ties through the four holes
provided on each placard. All warning signs and placards must be installed
where visible in the area of the gate.
14. To AVOID damaging gas, power, or other underground utility lines, contact
underground utility locating companies BEFORE digging.
15. SAVE THE INSTRUCTIONS.
