SAFETY REQUIREMENTS
VEHICULAR TRAFFIC ONLY
WARNING
This automatic gate operator is not designed nor is it intended for pedestrian tra
ffi
c. Vehicular gate operators must by
their nature be powerful to function reliably. This power can cause injury or death. Accordingly, direct all pedestrian tra
ffi
c
to a separate walk-through gate.
Install this gate operator only when:
The operator is appropriate for the construction of the
gate and the usage Class of the gate.
All openings of a horizontal slide gate are guarded or
screened from the bottom of the gate to a minimum of
1.83 m (6 ft) above the ground to prevent a 57.2 mm (2-1/4
in) 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.
All exposed pinch points are eliminated or guarded.
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 shall 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 or pressure relief valve
to compensate for an improperly installed, improperly
functioning, or damaged gate.
Permanently mounted controls intended for user activation
must be located at least 1.83 m (6 ft) 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.
Exception: Emergency access controls only accessible
by authorized personnel (e.g.
fi
re, police, EMS) may be
placed at any location in the line-of-sight of the gate.
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,
in the area of the gate. Each placard is to be visible by
persons located on the side of the gate on which the placard
is installed.
For gate operators utilizing a non-contact sensor (Photo
Eye):
See instructions on the placement of non-contact
sensors for each type of application.
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.
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.
For a gate operator utilizing a contact sensor (Edge):
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.
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.
A wireless device 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 landscaping
or similar obstruction. A wireless device shall function
under the intended end-use conditions.
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 152 mm (6 in) but less than 406 mm (16 in) above
the ground at any point in its arc of travel, one or more
contact sensors shall be located on the bottom edge.
USE OF VEHICLE DETECTORS
Use of vehicle detectors (loop detectors) is strongly
encouraged to prevent damage to vehicles caused by gates
closing on them. This is not considered to be a safety item as
vehicle detectors cannot provide protection to pedestrians.
In some situations, photoelectric devices may be used as
vehicle detectors, but should be wired accordingly.
GATE CONSTRUCTION AND SAFETY
Gate construction plays a very important role in ensuring
the safety of any automated gate system. The standard for
gate construction is ASTM F2200. Below are key areas to
address in gate design for safety. For complete information
consult the standard. Copies of the standard are available at:
