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.
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 locations not intended to service the general public.
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.
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.
UL325 ENTRAPMENT PROTECTION
REQUIREMENTS
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.

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. 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. 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" (152mm) above the ground at any point in its arc of travel, one or more contact sensors shall be located on the
bottom edge.

DIP SWITCH SETTINGS
SAVE SWITCH S1-1
This switch (S1-1) is used to save the settings for switches 2
thru 5.
NOTE: When setting switches S2-5 the save switch must be
in the off position prior to setting or changing switches for the
change to be saved.
MAG DELAY ENABLE
This switch (S1-2) enables the Mag Lock feature. On an open
command there will be a .5 second delay before the motor
starts, to allow the Maglock to release.
MODE DUAL/SINGLE
This switch (S1-3) sets the mode as Dual or Single
(See Programming section for mode).
SAFETY INPUTS
Swing gates allow four safety inputs. A DIP switch is required
for determining between N/O and N/C edges and N/O and N/C
eyes.
EDGE INPUT
Set switch (S1-4) to the following settings:
N/O Edge (Active Close) = 8.2K, 10K Edge, N/O dry
contact edge
N/C Edge (Active Open) = N/C dry contact edge
NOTE: Monitored Edges should be set in the N/O position,
as the activation condition is shorting the terminals.
EYE INPUT
This switch (S1-5) differentiates between N/O and N/C dry
contact photoelectric eye inputs.
NOTE: Pulsing Chamberlain photoelectric eyes will
automatically learn in N/O mode.

operator it is within ten percent of the operators rating.
DESCRIPTION
IMPORTANT SAFETY INSTRUCTIONS
To reduce the risk of SEVERE INJURY or DEATH:
1. READ AND FOLLOW ALL INSTRUCTIONS.
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
