USAutomatic gate operators are certified to UL325 Vehicular Class I, II, III and IV swing gate standards.
UL325 identifies four different classes of gate operators. These classes are:
Class I
: Residential vehicular gate operator- 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.
Class II
: Commercial/General access vehicular gate operator- vehicular gate operator (or system)
intended for use in a commercial location or building such as multi-family housing unit (five or
more single family units), hotel garages, retail, or other buildings servicing the general public.
Class III
: Industrial/Limited access vehicular gate operator- vehicular gate operator (or system)
intended for use in an industrial location or building such as a factory or loading dock area or
other locations not intended to serve the general public.
Class IV
: Restricted Access vehicular gate operator- vehicular gate operator (or system) intended
for use in a guarded industrial location or building such as an airport security area or other
restricted access locations not servicing the general public, in which unauthorized access is
prevented via supervision by security personnel.
INSTALLATION
Install the gate operator when:
• Operator is appropriate for the construction of the gate and usage class is correct for the
installation.
• All exposed pinch points are eliminated or guarded.
• The gate is a vehicle gate. Pedestrians must be supplied with a separate access opening.
• The gate is installed in a location where enough space is supplied between adjacent structures and
the gate that when opening or closing the chance of entrapment is reduced.
• The gate does not swing into public access areas.
• The gate is properly installed and swings freely in both directions. Do not over adjust the sensitivity
adjustment to compensate for an improper gate installation.
• All controls are located at least six feet away from the gate to eliminate the chance of the person
operating the gate from coming in contact with the moving gate. Do not install external buttons,
which can be used to operate the gate within the reach of children.
• Placards are installed, one on each side of the gate and visible in the gate area.
• All contact sensors used for secondary entrapment safety devices and their wiring is installed in a
manner which protects them from mechanical damage.
• All non-Contact sensors used for secondary entrapment safety devices are located so that the
signal from the transmitter to the receiver is not interfered with by adjacent structures. All exposed
wiring must also be protected from mechanical damage.
SECONDARY ENTRAPMENT DEVICES
USAutomatic designs all control boards with secondary entrapment inputs. USAutomatic
recommends that UL325 listed secondary safety devices be installed with all installations.
USAutomatic recommends that these devices be connected after proper gate installation and
operation has been verified. Then connect one device at a time to verify proper operation before
installing the next device. Ensure that power is disconnected from the control board prior to wiring
any accessory.
