Please Read This First
Thank you for purchasing the Mighty Mule Diamond. When correctly installed and properly used,
your LPA Diamond operators will give you many years of reliable service. Please read the following
information to ensure you have the correct system for your particular needs. This manual will
enable you to properly install your Diamond Automatic Gate Operators.
The Diamond operators are designed for installation on a pull-to-open dual leaf gates. The gates
must not exceed 16 feet in length nor weigh more than 500 pounds* (please see Technical
Specifications on page 1). The Diamond operators can be used on vinyl, aluminum, chain link, farm
tube, and wrought iron gates. Use on solid (wood) gates is not recommended. Solid surface
gates have a high resistance to the wind. If the wind is strong enough, the operators will
obstruct, stop, and blow fuses.
The Diamond operators accommodates extra transmitters, digital keypads, solar panels, push
buttons, automatic gate locks, and other access control products. These optional accessories
are noted with the
The Diamond can be installed on push-to-open gates with the addition of two (2) push-to-open brackets
[FM148].
symbol.
The Diamond operators feature adjustable stall force. This safety feature makes the gate stop
and reverse direction within two seconds when it comes in contact with an obstruction. The “MIN”
setting means the gate will exert the minimum force on an obstruction before it stops and reverses
direction.
The Diamond operators also have an adjustable auto-close feature. It can be set to remain open
from 3 to 120 seconds before automatically closing. Pressing the transmitter button at any time
after the gate fully opens will cause it to close immediately. “OFF” is the factory setting; meaning
the gate will stay open until you press the transmitter button (or keypad, etc.) again.
Please call LPA at (800) 543-4283 for more information about our professional line of gate operators
and accessories. Our Sales Department will be glad to give you the name and phone number of a
Mighty Mule dealer near you.

For The Consumer
WARNING: To reduce the risk of injury or death:
1. READ AND FOLLOW ALL INSTRUCTIONS. Failure to meet the requirements set forth in the instruction manual
could cause severe injury or death, for which the manufacturer cannot be held responsible.
2. When designing a system that will be entered from a highway or main thoroughfare, make sure the system is
placed far enough from the road to prevent traffic congestion.
3. The gate must be installed in a location that provides adequate clearance between it and adjacent structures when
opening and closing to reduce the risk of entrapment. Swinging gates must not open into public access areas.
4. The gate and gate opener installation must comply with any applicable local codes.
I. Before Installation
1. Verify this opener is proper for the type and size of gate, its frequency of use, and the proper class rating.
2. Make sure the gate has been properly installed and swings freely in both directions. Repair or replace all worn
or damaged gate hardware prior to installation. A freely moving gate will require less force to operate and will
enhance the performance of the opener and safety devices used with the system.
3. Review the operation of the system to become familiar with its safety features. Understand how to disconnect the
opener for manual gate operation (page iii).
4. This gate opener is intended for VEHICULAR GATES ONLY. A separate entrance or gate must be installed for
pedestrian use (page vi).
5. Always keep people and objects away from the gate and its area of travel. NO ONE SHOULD CROSS THE
PATH OF A MOVING GATE.
6. Pay close attention to the diagram below and be aware of these areas at all times.

IMPORTANT SAFETY INSTRUCTIONS
II. During Installation
1. Install the gate opener on the inside of the property and fence line. DO NOT install an opener on the outside of the
gate where the public has access to it.
2. Be careful with moving parts and avoid close proximity to areas where fingers or hands could be pinched.
3. Devices such as contact sensors (safety edges) and non contact sensors (photo beams) provide
additional protection against entrapment.
4. If push buttons or keypads are installed, they should be within sight of the gate, yet located at least 10 feet from
any moving part of the gate (see diagram below). Never install any control device where a user will be
tempted to reach through the gate to activate the gate opener.
5. Do not activate your gate opener unless you can see it and can determine that its area of travel is clear of people,
pets, or other obstructions. Watch the gate through its entire movement.
6. Secure outdoor or easily accessed gate opener controls in order to prohibit unauthorized use of the gate.

III. After Installation
1. Attach the warning signs (included) to each side of the gate to alert the public of auto matic gate operation. It
is your responsibility to post warning signs on both sides of your gate. If any of these signs or warning decals
become damaged, illegible or missing, replace them immediately. Contact GTO for free replacements.
2. The gate is automatic and could move at any time, posing a serious risk of entrapment. No one should be in
contact with an activated gate when it is moving or stationary.
3. Do not attempt to drive into the gate area while the gate is moving; wait until the gate comes to a complete stop.
4. Do not attempt to “beat the gate” (drive through) while the gate is closing. This is extremely dangerous.
5. Do not allow children or pets near your gate. Never let children operate or play with gate controls. Keep ALL
gate controls away from children and unauthorized users; store controls where children and unauthorized users do
not have access to them.
6. KEEP GATE AND GATE OPENER PROPERLY MAINTAINED. Always turn power to opener OFF before
performing any maintenance. Regularly grease the gate hinges. Apply silicone spray to a soft, dry cloth and clean
the push-pull tube at least once a month.

Required Safety Precautions for Gates
Install Warning Signs
Warning signs alert people of automatic gate operation and are required when installing the LPA Gate Operator. The
Warning Signs included must be installed on both sides of each gate. Furthermore, a walk-through gate must be installed
for pedestrian traffic. We recommend using the GTO Bulldog Pedestrian Gate Lock [FM145] for controlled access.
Entrapment Protection
The operator’s inherent obstruction settings, even when properly adjusted, may not be sensitive enough to prevent
bodily injury in some circumstances. For this reason, safety devices such as safety edge sensors (or photoelectric
sensors), which stop and reverse gate direction upon sensing an obstruction, are suggested for enhanced protection
against entrapment.

IMPORTANT SAFETY INSTRUCTIONS
Secondary Means of Protection Against Entrapment
As specified by Gate Operator Safety Standard, UL 325 (30A.1.1), automatic gate operators shall have an inherent
entrapment sensing system, and shall have provisions for, or be supplied with, at least one independent secondary
means to protect against entrapment. The Diamond utilizes Type A, an inherent (i.e., built-in) entrapment sensing system
as the primary type of entrapment protection. Also, the Diamond has provisions for the connection of Type B1 or B2
protection to be used as the secondary type of entrapment protection, if desired.
1. For gate operators utilizing a non-contact sensor (e.g., photo-electric sensor– Type B1) in accordance with UL 325
(51.8.4 [h]):
A. Refer to the sensor manufacturer’s instructions on the placement of non-contact sensors 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.
2.
For gate operators utilizing a contact sensor (e.g., safety edge sensor– Type B2) in accordance with UL 325 (51.8.4 [i]):
A. One or more contact sensors shall be located at the leading edge, bottom edge, and post edge, both inside and
outside of a vehicular swing gate system.
B. A hard wired contact sensor shall be located and its wiring arranged so that the communication between the
sensor and the gate operator is not subjected to mechanical damage.
C. A wireless contact sensor such as 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.
You may want to consider adding photo beams to your installation. GTO Photo Beams [R4222] provide a “non
contact” means of entrapment protection.

ENTRAPMENT ALARM (UL 325; 30A.1.1A)
The Diamond Gate Operator is designed to stop and reverse within 2 seconds when the gate comes in contact with
an obstruction. Additionally, these operators are equipped with an audio entrapment alarm which will activate if the
unit obstructs twice while opening or closing. This alarm will sound for a period of 5 minutes, or until the operator
receives an intended signal from a hard wired entry/exit source (e.g. push button control or keypad) and the gate
returns to a fully open or fully closed position. Turning the power switch on the control box OFF and back ON will also
deactivate the alarm. Wireless controls such as transmitters and wireless keypads will not deactivate the alarm.
