The LA400 is intended for use with vehicular swing gates. The opener can be used in Class I, Class II and Class III applications.
CLASS I – RESIDENTIAL VEHICULAR GATE OPERATOR
A vehicular gate operator (or system) intended for use in a home of one-to four single family dwelling, 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, garages, retail store or other building
servicing the general public.

UL325 ENTRAPMENT PROTECTION
REQUIREMENTS
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
four types of entrapment protection systems recognized by
UL325 for use on this operator.
Gate Operator Entrapment Protection
UL325
Swing and Gate Barrier
Installation
(Arm) 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 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.

B2 or E
Class
The chart above illustrates the entrapment protection
requirements for each of the three 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.
Moving Gate Can Cause
Injury or Death
KEEP CLEAR! Gate may move at any
time without prior warning.
Do not let children operate the gate or
play in the gate area.

S A F ET Y I N S TA L L AT I O N I N F O R M AT I O N
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 slide 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 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.
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 intended for user activation must be located at least six feet (6') 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. Outdoor or easily accessible controls shall have a
security feature to prevent unauthorized use.
9. The Stop and/or Reset (if provided separately) must be located in the line-of-sight of the gate. Activation of the reset control shall not cause the
operator to start.
10. A minimum of two (2) WARNING SIGNS shall be installed, one on each side of the gate where easily visible.
11. For a gate operator utilizing a non-contact sensor:
a. Reference owner’s manual regarding 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 where the risk of entrapment or obstruction exists, such as 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. 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.
d. 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.
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.
f. One or more contact sensors shall be located at the bottom edge of a vertical barrier (arm).

WARNING
To reduce the risk of SEVERE INJURY or DEATH:
• ANY maintenance to the operator or in the area near the
operator MUST not be performed until disconnecting the
electrical power and locking-out the power via the operator
power switch. Upon completion of maintenance the area MUST
be cleared and secured, at that time the unit may be returned
to service.
• Disconnect power at the fuse box BEFORE proceeding.
Operator MUST be properly grounded and connected in
accordance with local electrical codes. NOTE: The operator
should be on a separate fused line of adequate capacity.
• ALL electrical connections MUST be made by a qualified
individual.
• DO NOT install ANY wiring or attempt to run the operator
without consulting the wiring diagram. We recommend that
you install an optional reversing edge BEFORE proceeding with
the control station installation.
• ALL power wiring should be on a dedicated circuit and well
protected. The location of the power disconnect should be
visible and clearly labeled.
• ALL power and control wiring MUST be run in separate
conduit.
• BEFORE installing power wiring or control stations be sure to
follow ALL specifications and warnings described below.
Failure to do so may result in SEVERE INJURY to persons
and/or damage to operator.
All power wiring should be on a dedicated circuit and well protected.
NOTE: Calculated using NEC guidelines. Local codes and conditions must be reviewed for suitability of wire installation.
The transformer is tie-wrapped at the factory for shipping. The
transformer can be plugged into a receptacle external to the
control box. You can run low voltage wire between the
transformer and control box. This will create more space in the
control box for accessories.
Alternatively, you can connect 120Vac directly to the box, and
plug the transformer to the receptacle inside the control box.

2. NEVER let children operate or play with gate controls.
Keep the remote control away from children.
3. ALWAYS keep people and objects away from the gate.
NO ONE SHOULD CROSS THE PATH OF THE MOVING
GATE.
4. Test the gate operator monthly. The gate MUST reverse
on contact with a rigid object or stop when an object
activates the non-contact sensors. After adjusting the
force or the limit of travel, retest the gate operator.
Failure to adjust and retest the gate operator properly
can increase the risk of INJURY or DEATH.
5. Use the emergency release ONLY when the gate is not
moving.
6. KEEP GATES PROPERLY MAINTAINED. Read the
owner’s manual. Have a qualified service person make
repairs to gate hardware.
7. The entrance is for vehicles ONLY. Pedestrians MUST
use separate entrance.
8. Disconnect ALL power BEFORE performing ANY
maintenance.
9. ALL maintenance MUST be performed by a LiftMaster
professional.

and returned pre-paid. Defective parts will be repaired or replaced with new or factory-rebuilt parts at Seller’s sole option.
ALL IMPLIED WARRANTIES FOR THE PRODUCT, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED IN DURATION TO THE TWO YEAR LIMITED
WARRANTY PERIOD SET FORTH ABOVE, AND NO IMPLIED WARRANTIES WILL EXIST OR APPLY AFTER SUCH PERIOD. Some
States do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you. THIS LIMITED
WARRANTY DOES NOT COVER NON-DEFECT DAMAGE, DAMAGE CAUSED BY IMPROPER INSTALLATION, OPERATION OR CARE
(INCLUDING, BUT NOT LIMITED TO ABUSE, MISUSE, FAILURE TO PROVIDE REASONABLE AND NECESSARY MAINTENANCE,
UNAUTHORIZED REPAIRS OR ANY ALTERATIONS TO THIS PRODUCT), LABOR CHARGES FOR REINSTALLING A REPAIRED OR

CONNECTION WITH USE, OR INABILITY TO USE, THIS PRODUCT. IN NO EVENT SHALL SELLER’S LIABILITY FOR BREACH OF
WARRANTY, BREACH OF CONTRACT, NEGLIGENCE OR STRICT LIABILITY EXCEED THE COST OF THE PRODUCT COVERED HEREBY.
NO PERSON IS AUTHORIZED TO ASSUME FOR US ANY OTHER LIABILITY IN CONNECTION WITH THE SALE OF THIS PRODUCT.
Some states do not allow the exclusion or limitation of consequential, incidental or special damages, so the above limitation or
exclusion may not apply to you. This limited warranty gives you specific legal rights, and you may also have other rights which vary
from state to state.
