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, safe-
ty features must be incorporated into every design. Specific safety features include:
Gate Edges Guards for exposed rollers Photo-Electric Sensors
Screen Mesh Enclosed Track Vertical Posts
Instructional and Precautionary Signage
4. Install the gate operator only when:
a) The operator is appropriate for the construction and the usage class of the gate.
b) 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 1/4inch (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.
c) All exposed pinch points are eliminated or guarded, and guarding is supplied for exposed rollers.
5. The operator is intended for installation only on gates used for vehicles. Pedestrians must be supplied with a sepa-
rate access opening.
6. The gate must be installed in a location so that enough clearance is supplied between the gate and adjacent struc-
tures when opening and closing to reduce the risk of entrapment.
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.
9. 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.
10. All warning signs and placards must be installed where visible in the area of the gate.
11. For a gate operator utilizing a non-contact sensor:
a) See instructions on the placement of non-contact sensor for each type of application.
b) 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.
c) 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.
12. For a gate operator utilizing a contact sensor such as an edge sensor:
a) 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.
b) One or more contact sensors shall be located at the bottom edge of a vehicular vertical lift gate.
c) One or more contact sensors shall be located at the pinch point of a vehicular vertical pivot gate.
d) 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.
e) A wireless contact sensor such as the 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.
