SAFETY ACCESSORY SELECTION

UL325 ENTRAPMENT PROTECTION REQUIREMENTS

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
Installation
CLASS

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.

A, B1, B2 or E

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.

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.

SAFETY » SAFETY INSTALLATION INFORMATION
9. The Stop and/or Reset (if provided separately) must be located in the lineof-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.

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 feet (1.2 m) above the ground to
prevent a 2-1/4 inch (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.

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 inches (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).

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 6 feet (1.83 m)
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.

SAFETY » IMPORTANT SAFETY INFORMATION
INSTALLATION

To prevent SERIOUS INJURY or DEATH; one or more non-contact sensors shall be
located where the risk of entrapment or obstruction exists.
To prevent SERIOUS INJURY or DEATH from a moving gate:
• Entrapment protection devices MUST be installed to protect anyone who may
come near a moving gate.
• Locate entrapment protection devices to protect in BOTH the open and close
gate cycles.
• Locate entrapment protection devices to protect between moving gate and
RIGID objects, such as posts.
• A swinging gate shall NOT open into public access ways.

To prevent SERIOUS INJURY or DEATH from a moving gate:
• Install warning signs on the front and back of the gate in PLAIN VIEW.
• Permanently secure each warning sign in a suitable manner using fastening
holes.
ALWAYS wear protective gloves and eye protection when changing the battery or
working around the battery compartment.
• DO NOT use flooded lead acid battery.
• Flooded lead acid batteries will produce gases when discharging and
recharging which can explode.
• DO NOT dispose of battery in fire. Battery may explode. Check with local
codes for disposal instructions.

WIRING

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.

To AVOID damaging plug-in transformer, it MUST be enclosed in a suitable
weatherproof enclosure and provided with proper weatherproof fixtures.
To AVOID damaging gas, power or other underground utility lines, contact
underground utility locating companies BEFORE digging.

To reduce the risk of FIRE or INJURY to persons use only LiftMaster part
#K74-30762 for replacement batteries.

ADJUSTMENT

Without a properly installed safety reversal system, persons (particularly small
children) could be SERIOUSLY INJURED or KILLED by a closing gate.
• Too much force on gate will interfere with proper operation of safety reversal
system.
• NEVER increase force beyond minimum amount required to close gate.
• NEVER use force adjustments to compensate for a binding or sticking gate.

• If one control (force or travel limits) is adjusted, the other control may also
need adjustment.
• After ANY adjustments are made, the safety reversal system MUST be tested.
Gate MUST reverse on contact with a rigid object.

SAFETY » IMPORTANT SAFETY INFORMATION
OPERATION AND MAINTENANCE

• READ AND FOLLOW ALL INSTRUCTIONS.
• NEVER let children operate or play with gate controls. Keep the remote control
away from children.
• ALWAYS keep people and objects away from the gate. NO ONE SHOULD
CROSS THE PATH OF THE MOVING GATE.
• 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.

• Use the emergency release ONLY when the gate is not moving.
• KEEP GATES PROPERLY MAINTAINED. Read the ownerʼs manual. Have a
qualified service person make repairs to gate hardware.

Before proceeding, begin with the gate in the fully closed position. There are two
methods for determining the proper location of the post brackets:
• Paper template (Located on the back page of this manual. Must be cut out.)
• Tape measure.
Either method will work depending on preference.

SET THE BIPART DELAY
(MODEL LA400-S ONLY)

In some dual gate installations, one gate will need to open first and close second.
This would happen if there was an ornamental overhang on one gate or if using a
solenoid lock, for example. This gate is called the Primary gate and needs to be
connected to Gate 1 connections on the control board. Thus, it is preferred that the
control box be installed on the same side as this gate. If there is no appropriate
location on that side for the control box, then mount the control box on the opposite
side, but connect the operator closest to the control box to the Gate 2 connector and
the operator on the opposite side to the Gate 1 connector.
NOTE: The gate with the longer travel span (opening) must be set as the primary
gate (GATE 1).

The limits are internal settings that indicate when the gates are in the fully open position and the fully closed position. For proper functionality, the limits must be
programmed during the installation process. The programming uses a combination of buttons on the control board.
The specific buttons used for programming depends on which side of the gate the control box is mounted and how many operators the installation includes.
Refer to pages 11 and 12 to determine if the gate is Left-handed or Right-handed.
If a mistake is made during programming press the RESET button on the outside of the control box to start over. The programming times-out automatically after

• The gate with the longer travel span (opening) must be set as the primary gate (GATE 1).
• If one gate is overlapping the other, the gate that is overlapping must be connected to GATE 1 so it will start moving before the other gate; GATE 2 may need to be closed
first if there is overlap or a gate lock is being used.
• The programming can be exited at any time by pressing the RESET button. Programming times-out automatically after 60 seconds of inactivity.

ADJUSTMENT » FORCE ADJUSTMENT + TIMER-TO-CLOSE (TTC)
Without a properly installed safety reversal system, persons (particularly small
children) could be SERIOUSLY INJURED or KILLED by a closing gate.
• Too much force on gate will interfere with proper operation of safety reversal
system.
• NEVER increase force beyond minimum amount required to close gate.
• NEVER use force adjustments to compensate for a binding or sticking gate.

FORCE ADJUSTMENT

The operator is equipped a with an obstruction current sensing feature. If the gate
encounters an obstruction the operator will automatically reverse direction and stop.
Based on the length and weight of the gate it may be necessary to make force
adjustments. The force adjustment should be high enough that small objects such as
branches or wind will not cause nuisance interruptions but low enough to prevent
serious injury to a person or a vehicle.
TO ADJUST THE FORCE
Using the 3-button remote or the Single Button Control (SBC) button on the
control board, open and then close the gate.

FORCE

If the gate stops or reverses before reaching the fully open or closed position
increase the force by turning the force control slightly.

the force by making sure the gate will stop and reverse on contact with an
4 Testobstruction.

NOTE: Weather conditions can affect the gate movement, so seasonal adjustment
may be required. The force control is factory set to the mid position.

TIMER-TO-CLOSE (TTC)

The Timer-to-Close feature can be set to automatically close the gate after a specified
time period. The TTC is factory set to OFF.
If the TTC is set to the OFF position, then the gate will remain open until the operator
receives another command from a remote control or SBC. The gate must be fully
open for the timer feature to activate and close the gate.

TIMER TO
CLOSE

TO SET THE TIMER-TO-CLOSE
Rotate the Timer-to-Close dial to the desired setting. The range is 0 to
180 seconds, 0 seconds is OFF. The "TIMER RUNNING LED" will flash once
for every second of adjusted time.
NOTE: Any radio command, SBC or CLOSE command on the control board prior to
the TTC expiring will close the gate. The TTC is reset by any signals from the loops,
close edges and close photoelectric sensors (IR’s).

The reset button is located on the outside of the control box and serves several
functions.
PROGRAMMING LIMITS RESET

If a mistake is made while programming the limits press the reset button to
start over.
OPERATOR ALARM

The operator alarm will sound under the following condition: If gate encounters
two consecutive obstructions, before reaching the open or close limit, the
operator will stop, the alarm will sound (up to 5 minutes) and the control board
will require resetting. No commands will operate the gate during this time.
Reset the control board by pressing the reset button. After the operator is reset,
normal functions will resume.

RESET

Reset Button

PARTY MODE (TIMER DEFEAT - HOLD OPEN)

When the Timer-to-Close feature is activated for normal daily operation and
you wish to leave the gate(s) in the open position for any extended period of
time you can activate the Party Mode.
To set Party Mode: open the gate fully, then press the reset button. The next
command given by remote control or SBC on the control board will close the
gate and return the operator to normal operation.
REMOTE CONTROL

Once the remote control has been programmed operator will operate as follows:
When gate is in the closed position, activation of the remote control button will open
the gate. During the open cycle another activation of the remote control will stop the
gate and the next activation of the remote control will close the gate.
When the gate is in the open position, activation of the remote control button will
close the gate.

MANUAL RELEASE

In case of a power failure, the operator can be disengaged from the gate. With an
operator, the release action may sometimes feel stiff/jerky, which is normal and has
no effect on function.
