SAFETY INSTALLATION INFORMATION  
1. READ and FOLLOW all instructions.  
9. For an installation utilizing non-contact sensors (safety  
sensors), see product manual on the placement of  
non-contact sensors (safety sensors) for each type of  
application.  
2. The gate operator is intended for use with Class I  
vehicular swing gates.  
Class I denotes a 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.  
a. Care shall be exercised to reduce the risk of  
nuisance tripping, such as when a vehicle trips the  
safety sensor while the gate is still moving.  
b. One or more non-contact sensors (safety sensors)  
shall be located where the risk of entrapment or  
obstruction exists, such as the perimeter reachable  
by a moving gate or barrier.  
Install the gate operator only when the operator is  
appropriate for the construction and the usage class of  
the gate.  
3. 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 system  
design and installation must reduce public exposure to  
potential hazards. Install the gate operator only when  
the operator is appropriate for the construction of the  
gate and the usage class of the gate. All exposed pinch  
points must be eliminated or guarded.  
10. 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. 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.  
4. A gate operator can create high levels of force during  
normal operation. Therefore, safety features must be  
incorporated into every installation. Specific safety  
features include safety sensors.  
11. Never mount any device that operates the gate  
operator where the user can reach over, under, around  
or through the gate to operate the controls. Controls  
are to be placed at least 6' (1.8 m) from any part of the  
moving gate:  
5. The gate must be properly installed and work freely in  
both directions prior to the installation of the gate operator.  
6. The gate must be installed in a location so that enough  
clearance is provided 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.  
• A hard wired control device shall be located and its  
wiring arranged so that communication between the  
control device and the gate operator is not subject to  
mechanical damage.  
7. The operator is intended for use 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. The  
pedestrian access shall be located such that persons  
will not come in contact with the moving vehicular gate.  
8. Pedestrians should never cross the pathway of a  
moving gate. The gate operator is not acceptable for  
use on any pedestrian gate. Pedestrians must be  
supplied with a separate pedestrian access.  
12. 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. Never  
allow anyone to hang on or ride the gate during the  
entire travel of the gate.

13.Each gate operator is provided with two safety warning  
placards. The placards are to be installed on the front  
and back of the gate where they are plainly visible. The  
placards may be mounted using cable ties through the  
four holes provided on each placard.  
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.  
All warning signs and placards must be installed  
where visible in the area of the gate.  
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.  
This entrance is for vehicles only.  
14. To AVOID damaging gas, power, or other underground  
utility lines, contact underground utility locating  
companies BEFORE digging.  
Pedestrians must use separate entrance

Connect the Gate Operator (Gate 2) to the Control Box (Model LA412-S Only)  
Occasionally in 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).  
SET THE LOCK/BIPART DELAY  
The LOCK/BIPART DELAY switch on the control  
board needs to be set to the ON position.  
The following illustration shows a dual gate  
configuration with a decorative overlapping piece on  
the outside of the gate.

SOLAR PANEL INSTALLATION  
Select Site for Solar Panel(s)  
The solar panel(s) must be located in an open area clear of obstructions and shading for the entire day. The solar  
panel(s) comes with a 10' cable. If a location near the control box cannot be found, an additional cable will be required.  
The LA412 Solar Gate Operator is not supported in northern climates where temperatures reach below -4F. This is due  
to cold weather and a reduced number of hours of sunlight during the winter months. Cycle rate may vary from solar chart  
for areas that reach below 32F. Solar panels should be cleaned on a regular basis for best performance to ensure proper  
operation.

The map (above) and cycles/day ratings are approximations and do not account for installed accessories that draw  
additional battery power. Ratings vary based on gate construction and installation. They are also shown for using a single  
10W solar panel in conjunction with two 12 Volt 7.0 AH batteries. Ratings will improve by adding additional 10W solar  
panels. If required, up to three 10W panels (30W total) can be wired in parallel to increase the number of cycles per day.  
NOTE: The solar panel(s) recommendation is based upon the average solar radiation and the temperature effects on batteries in the  
given regions. Local geography and weather conditions may require additional solar panels. Solar panels cannot be installed in areas that  
experience heavy fog or lake effect rain and snow.

OVERVIEW OF SOLAR PANEL INSTALLATION  
Make sure the control box has two 12V 7AH batteries installed. Do not connect  
batteries until instructed.

POSITION SOLAR PANEL(S)  
NOTE: If the panel(s) is not casting a shadow, the battery is not being charged.

The location of the panel(s) is critical to the success of the installation. In general, the panel(s) should be mounted  
using the provided angle bracket facing due south. The solar panel(s) should be mounted in an area clear of all  
obstructions and shading from buildings and trees. The area should be clear for a 180° arc from due east of the  
panel(s) location to due west of the panel(s) location.  
NOTE: Tall trees or buildings that do not shade the solar panel(s) in the summer could shade the solar panel(s) during the winter  
months when the sun sits lower in the sky.  
Sun’s Position  
Solar Panel  
TIP: To optimize the system for  
winter operation the angle can be  
increased an additional 15° (solar  
panel(s) sits more vertical).  
NOTE: DO NOT install solar panel near potential  
South  
shading or obstructions that will block the panel  
during any part of the day.  
TIP: The area around the solar panel(s)  
should be clear of shadows or obstructions  
to the sun for a 180° arc east to west.  
South  
180°  
TIP: Wire runs should be kept as short as possible.  
The solar panel(s) can be located up to 100' from the  
operator using #16 AWG wire in any direction, including  
elevating it.

CONNECT SOLAR PANEL(S) TO OPERATOR CONTROL BOX  
Open the control box cover. Disconnect all power and  
batteries from the control board. Run the solar panel  
cable to the bottom of the control box. Thread the  
cable through the watertight connector and pull the  
cable through until it reaches the AC PWR/SOLAR  
connector on the control board. Tighten the watertight  
connector on the cable. Attach the solar panel wires  
to AC PWR/SOLAR input terminal (polarity is not  
important). Leave the AC PWR/SOLAR earth ground  
connection open.  
7
To avoid SERIOUS INJURY or DEATH from a moving gate:  
• Disconnect ALL electric and battery power BEFORE  
performing ANY service or maintenance.  
• DO NOT connect more than 3 solar panels.  
• DO NOT connect solar panel(s) when power supply is  
connected.  
NOTE: The system is designed to be charged by either an AC plug-in transformer or a separate solar panel, but not both.  
Connect the AC PWR/SOLAR connector to the control board. With the batteries still disconnected, the control board  
should power up if the solar panel is correctly installed and the sun is shining (the diagnostic LED will blink).  
Use the cable ties to secure the solar panel cable away from places where it could be damaged.  
NOTE: If the sky is too overcast to allow the solar panel to power up the system, the panel will need to be verified at another time  
when the sun is shining. There is no other way to verify the panel installation.

To reduce the risk of FIRE or INJURY to persons use ONLY  
LiftMaster part 27-NP712 for replacement batteries.  
NOTES: Batteries will degrade over time depending on  
temperature and usage. For best performance, the batteries  
should be changed every 3 years.  
Batteries do not perform well in extremely cold  
temperatures.

PROGRAMMING  
Program Limits  
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 13 to determine if the gate is Left- or Right-handed.  
If a mistake is made during programming press the RESET button on the outside of the control box to start over.  
SINGLE ARM LEFT-HAND SIDE

Force and Timer to Close  
FORCE 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.  
The operator is equipped a with an obstruction 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:  
• 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.  
Using the 3-button remote or the Single Button Control  
(SBC) button on the control board, open and then close  
the gate. If the gate stops or reverses before reaching the  
fully open or closed position increase the force by turning  
the force control slightly. Run operator through a complete  
cycle.  
NOTE: Weather conditions can affect the gate movement,  
so seasonal adjustment may be required. The force  
control is factory set to the mid position.

OPERATION AND MAINTENANCE  
IMPORTANT SAFETY INSTRUCTIONS  
WARNING  
To reduce the risk of SEVERE INJURY or DEATH:  
1. READ AND FOLLOW ALL INSTRUCTIONS.  
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.  
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.  
7. The entrance is for vehicles ONLY. Pedestrians MUST use  
separate entrance.  
8. Disconnect ALL power BEFORE performing ANY  
maintenance.  
9.  
SAVE THESE INSTRUCTIONS.  
USING YOUR GATE OPERATOR  
Your operator will operate with up to forty-nine Security✚®  
remote controls and one Security✚® Keyless Entry System.  
If you purchase a new remote, or if you wish to deactivate  
any remote, follow the instructions in the Programming  
section.  
The Timer-To-Close (TTC) Feature comes from the  
factory in the OFF setting.  
The “TIMER RUNNING LED” will flash once for every  
second of adjusted time. The gate(s) must fully open for  
the timer feature to be active and close the gate(s). Any  
radio command or pressing the single button on the control  
board prior to the TCC time expiring will close the gate. The  
TTC is reset by any signals from the loops, close edges,  
and close safety sensors (IR’s).  
Activate your operator with any of the following:  
• The hand-held Remote Control (See Accessories):  
Hold the large push button down until the gate starts to  
move.  
Party Mode: If the Timer-to-Close feature is enabled and  
you would like the gate to remain open, simply push the  
reset button (located on the outside of the control box).  
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.  
• The Keyless Entry (See Accessories): If provided with  
your gate operator, it must be programmed before use.  
See Programming.  
When the operator is activated (with the safety  
sensors correctly installed and aligned)  
1. If open, the gate will close. If closed, it will open.  
2. If the gate has been stopped in a partially open position,  
it will close.  
3. If obstructed while closing, the gate will stop and reverse  
direction for approximately 2 seconds and then stop. The  
next command will open the gate.  
Sleep Mode (Battery Conservation): The operator enters  
sleep mode 10 seconds after the last command is given.  
The diagnostic LED will blink in this mode. The safety  
sensors (photo eyes) indicator LEDs will not be on. The  
next command given will return the operator to normal  
operation.  
4. If obstructed while opening, the gate will stop and  
reverse direction for approximately 2 seconds and then  
stop. The next command will close the gate.  
Reset Button: The reset  
button can be used to set the  
operator into party mode and  
to reset the alarm after an  
obstruction. The diagnostic  
LED can be reset by holding  
the reset button for 1 to 2  
seconds.  
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. Reset the control board by  
pressing the “Reset Button” located on the outside of  
the control box. No commands at this time will operate  
gate. After the operator is reset, normal functions will be  
available.
