SAFETY
IMPORTANT SAFETY INFORMATION
To reduce the risk of SEVERE INJURY or DEATH from an incorrect installation:
1. Vehicular gate systems provide convenience and security. Gate systems are comprised
of many component parts. The gate operator is only one component. Each gate
system is specifically designed for an individual application.
2. 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 systems design and installation must reduce public exposure to potential
hazards.
3. A gate operator can create high levels of force in its function as a component part of a
gate system. Therefore, safety features must be incorporated into every design.
Specific safety features include:
• Gate Edges • Guards for exposed rollers • Photoelectric Sensors
• Screen Mesh • Vertical Posts • Instructional and Precautionary Signage
4. Install the gate operator only when:
a. The operator is appropriate for the construction and the usage of the gate.
b. All openings of a horizontal swing gate are guarded or screened from the bottom of
the gate to a minimum of 4' (1.2 m) above the ground to prevent a 2 1/4" (6 cm)
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.
c. All exposed pinch points are eliminated or guarded, and guarding is supplied for
exposed rollers.
5. The operator is intended for installation on gates used for vehicles. Pedestrians should
be supplied with a separate access opening.
6. 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.
7. The gate must be properly installed and work freely in both directions prior to the
installation of the gate operator.
8. Controls must be far enough from the gate so that the user is prevented from coming
in contact with the gate while operating the controls.
