or a garage or parking area associated therewith.
CLASS II – COMMERCIAL/GENERAL ACCESS VEHICULAR GATE OPERATOR
A vehicular gate operator (or system) intended for use in a commercial location or building such as a
multi-family housing unit (five or more single family units) hotel, garage, retail store or other building
servicing the general public.
CLASS III – INDUSTRIAL/LIMITED ACCESS VEHICULAR GATE OPERATOR
A vehicular gate operator (or system) intended for use in a industrial location or building such as a
factory or loading dock area or other location not intended to service the general public.
CLASS IV – RESTRICTED ACCESS VEHICULAR GATE OPERATOR
A 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.
SAFETY ACCESSORY SELECTION
All UL325 compliant LiftMaster gate operators will accept external
entrapment protection devices to protect people from motorized
gate systems. UL325 requires that the type of entrapment
protection correctly matches each gate application. Below are the
six types of entrapment protection systems recognized by UL325
for use on this operator.
ENTRAPMENT PROTECTION TYPES
Type A: Inherent obstruction sensing system, self-contained
within the operator. This system must sense and initiate
the reverse of the gate within two seconds of contact
with a solid object.
Type B1: Connections provided for a non-contact device, such as
a photoelectric eye, can be used as a secondary
protection.
Type B2: Connections provided for a contact sensor. A contact
device, such as a gate edge, can be used for secondary
protection.
Type C: Inherent adjustable clutch or pressure relief valve.
Type D: Connections provided for a control
requiring continuous pressure to
operate the operator open and close.
Type E: Built-in audio alarm. Examples
include sirens, horns or buzzers.
NOTE: UL requires that all installations must
have warning signs placed in plain view on
both sides of the gate to warn pedestrians of
the dangers of motorized gate systems.
UL325 ENTRAPMENT PROTECTION REQUIREMENTS
The chart above illustrates the entrapment protection
requirements for each of the four UL325 classes.
In order to complete a proper installation you must satisfy the
entrapment protection chart shown above. That means that
the installation must have one primary means of entrapment
protection and one independent secondary means of
entrapment protection. Both primary and secondary
entrapment protection methods must be designed, arranged
or configured to protect against entrapments in both the open
and close directions of gate travel.
For Example: For a slide gate system that is installed on a
single-family residence (UL325 Class I) you must provide the
following: As your primary type of entrapment protection you
must provide Type A inherent (built into the operator)
entrapment sensing and at least one of the following as your
secondary entrapment protection: Type B1- Non-contact
sensors such as photoelectric eyes, Type B2- Contact sensors
such as gate edges or Type D- Constant pressure control.

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 class 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" (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 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.
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 must be installed where visible, on each side 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. 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. 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.
c. 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.
d. One or more contact sensors shall be located at the bottom edge of a vehicular vertical lift gate.
e. 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" (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.

NOT FOR USE AS PEDESTRIAN PASSAGE! This operator is
intended for vehicular use only. To prevent INJURY to
pedestrians, a separate pedestrian access should be supplied,
visible from the gate. Locate the pedestrian access where there is
not a chance of INJURY at any point during full movement of the
gate.
DO NOT MOUNT ACCESSORIES THAT ARE
ACCESSIBLE THROUGH GATE!
WARNING SIGN PLACEMENT
To prevent SERIOUS INJURY or DEATH from a moving gate:
• Install Warning signs on EACH side of gate in PLAIN VIEW.
• Permanently secure each Warning sign in a suitable
manner using fastening holes.
SAFETY PRECAUTIONS FOR OPEN ROLLER GATES
• Injuries occur when people get their hands or feet caught
between the top or bottom of the gate and the gate roller.
These potential pinch-points should be guarded against at all
times. Enclosed style gate tracks are available for refitting of
these rollers from many fence suppliers. Also, roller guards
are available for installing over the rollers.
• UL325 requires that, when used, contact sensors shall be
located at the leading edge, trailing edge, and be post
mounted both inside and outside of a vehicular horizontal
slide gate. Non-contact sensors such as photo eyes must
protect during both open and close gate cycles.
• Injuries occur when people put their hands and arms
through openings in the grill while the gate is operating.
They cannot retract their arm and it gets caught between the
moving gate grill and the stationary fence post or fence. This
potential hazard can be averted by placing a 4' (1.2 m)
screen mesh on the gate to prevent access through openings
anywhere the gate may travel. See Safety Brochure for
details. To prevent entrapment injuries, mount controls at
least 6' (1.8 m) from the gate or any moving parts of the
gate.
