PLEASE READ THIS FIRST

Thank you for purchasing a Mighty Mule FM402 Gate Opener—GTO’s “do-it-yourself” automatic gate opener!

When correctly installed and properly used, your Mighty Mule Gate Opener will give you many years of reliable service. Please read the following information and watch the enclosed video to ensure you have the correct system for your particular needs. Furthermore, this manual and the video will enable you to properly install your Mighty Mule Gate Opener.

The Mighty Mule Gate Opener is designed for installation on Pull-To-Open dual gate leaves (gates that open into the property). By purchasing accessory brackets [FM148], the Mighty Mule Gate Opener can accommodate Push-To-Open dual gate leaves (gates that open out from the property). Please see Pull-To-

Open/Push-To-Open diagram on page 3. The gates must not exceed 12 ft. or 300 lbs. per leaf (see Technical

Specifications on page 1). The Mighty Mule Gate Opener can be used on vinyl, aluminum, chain link, farm tube, and wrought iron gates.

Use on solid (surface) gates is not recommended. Solid surface gates have a high resistance to the wind. If the wind is strong enough, the opener will obstruct and stop, blow fuses, or

may damage the equipment.

The Mighty Mule Gate Opener features an adjustable stall force setting. This safety feature makes the gate stop and reverse direction within 2 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. You will

need to adjust the stall force for your particular application.

The Mighty Mule Gate Opener also has an adjustable auto-close feature. After the gate reaches the fully open position, it can be set for OFF, or to remain open up from 3 to 120 seconds before automatically closing.

Pressing the transmitter button at any time after the gate opens fully will cause it to close immediately. The auto-close factory setting is OFF, meaning the gate will stay open until you press the transmitter (or keypad, etc.) again.

The Mighty Mule Gate Opener accommodates extra transmitters, digital keypads, solar panels, push buttons, automatic gate locks, and other access control products. These optional accessories (page 26) are available

Special Order (if the accessory is not in stock). If your store cannot special order accessories, please call the

GTO Sales Department (850/575-0176) or visit www.mightymule.com.

PLEASE NOTE—If your application requires any of the following:

IMPORTANT SAFETY INSTRUCTIONS

Because automatic gate openers produce high levels of force, consumers need to know the potential hazards associated with improperly designed, installed, and maintained automated gate opener systems. Keep in mind that the gate opener is just one component of the total gate operating system.

Each component must work in unison to provide the consumer with convenience, security, and safety.

This manual contains various safety precautions and warnings for the consumer. Because there are many possible applications of the gate opener, the safety precautions and warnings contained in this manual cannot be completely exhaustive in nature. They do, however, provide an overview of the safe design, installation, and use of this product. CAREFULLY READ AND FOLLOW ALL SAFETY

PRECAUTIONS, WARNINGS, AND INSTALLATION INSTRUCTIONS TO ENSURE THE SAFE

SYSTEM DESIGN, INSTALLATION, AND USE OF THIS PRODUCT.

Precautions and warnings in this manual are identified with this warning symbol. The symbol identifies conditions that can result in damage to the opener or its components, serious injury, or death.

Because GTO automatic gate openers are only part of the total gate operating system, it is the responsibility of the consumer to ensure that the total system is safe for its intended use.

How To Manually Open and Close the Gate:

CAUTION: The gate can be opened and closed manually when the opener is disconnected.

ONLY disconnect the opener when the opener power switch is OFF and the gate is NOT moving.

Disconnecting the Opener

1. Turn opener power switch (Control Box) OFF.

2. Remove hairpin clip, clevis pin, and bushing from both the front and rear mounting points.

3. Remove the opener from the mount.

For The Consumer

WARNING: To reduce the risk of injury or death:

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.

Zone 4 – the space between the gate in the open position and any object such as a wall, fence, etc.

Zone 5 – pinch points between the opener and gate.

iv Mighty Mule FM402 Installation Instructions rev 12-14-15


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.

KEEP GATE AND GATE OPENER PROPERLY MAINTAINED. Always turn power to opener OFF before performing any maintenance. Regularly grease the gate hinges. Clean the push-pull tube with a soft, dry cloth and apply silicone spray to it at least once per month.

7. To operate this equipment safely, YOU must know how to disconnect the opener for manual gate operation (page iii). If you have read the instructions and still do not understand how to disconnect the opener, contact the GTO

Service Department.

8. Disconnect the opener ONLY when the power is TURNED OFF and the gate is NOT moving.

9. Make arrangements with local fire and law enforcement for emergency access.

10. Distribute and discuss copies of the IMPORTANT SAFETY INSTRUCTIONS section of this manual with all persons authorized to use your gate.

11.

IMPORTANT: Save these safety instructions. Make sure everyone who is using or will be around the gate and gate opener are aware of the dangers associated with automated gates. In the event you sell the property with the gate opener or sell the gate opener, provide a copy of these safety instructions to the

new owner.

Should you lose or misplace this manual, a copy can be obtained by downloading one from the Mighty

Mule web site (www.mightymule.com), by contacting GTO Access Systems, LLC., at 3121 Hartsfield Road,

Tallahassee, Florida 32303 or by calling 1-800-543-4283 and requesting a duplicate copy. One will be provided to you free of charge.

Required Safety Precautions for Gates

Install Warning Signs

Warning signs alert people of automatic gate operation and are required when installing the Mighty Mule Gate Opener.

The Warning Signs included must be installed on both sides of each gate. Furthermore, a walk-through gate must be installed if pedestrian traffic is expected near the vehicular gate. We recommend using the GTO Bulldog Pedestrian Gate

Lock [FM145] (page 26) for controlled access.

Entrapment Protection

GTO’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.

Secondary Means of Protection Against Entrapment

As specified by Gate Opener Safety Standard, UL 325 (30A.1.1), automatic gate openers 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 Mighty Mule utilizes Type A, an inherent (i.e., built-in) entrapment sensing system as the primary type of entrapment protection. Also, the Mighty Mule has provisions for the connection of Type

B2 protection to be used as the secondary type of entrapment protection, if desired.

1. For gate openers 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 opener is not subjected to mechanical damage.

C. A wireless contact sensor such as one that transmits radio frequency (RF) signals to the gate opener 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. Call Mightgy Mule Sales at 1-800-543-GATE (4283) for more information.

ENTRAPMENT ALARM (UL 325; 30A.1.1A)

The Mighty Mule Gate Opener is designed to stop and reverse within 2 seconds when the gate comes in contact with an obstruction. Additionally, these openers 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 opener 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.

Before You Begin

1. Determine Charging Options for Battery: Transformer OR Solar

NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT THE SAME TIME!

It will damage the control board!

IMPORTANT

• The battery charge is maintained by the 14 Volt transformer included OR optional solar panel(s). The transformer

OR solar panel is connected to the control board using low voltage, 16 gauge, dual conductor, stranded, direct burial wire [RB509] (page 26).

• All low voltage wire used with the Mighty Mule Gate Opener must be 16 gauge dual conductor, stranded, direct burial wire.

• The transformer is intended for indoor use. If the transformer can only be plugged into an outside electrical outlet, a weatherproof cover or housing must be used.

• If your gate is more than 1000' from an AC power source, you will need to use a solar panel charging kit

( minimum 10 watts). Refer to the Solar Panels and Gate Activity Chart below.

Solar Panel and Gate Activity Chart

The table and map illustrate the maximum number of gate cycles to expect per day in a particular area when using from 10 to 20 watts of solar charging power.

The figures shown are for winter (minimum sunlight) and do not account for the use of any accessory items.

Accessories connected to your system will draw additional power from the battery and will require additional solar panels.

NOTE: UP to 250 ft. of dual conductor, 16 guage, stranded wire may be used to allow installation of solar panels in direct sunlight.

IMPORTANT: To achieve the most efficient leverage for the gate opener and ensure long trouble free service, the gate opener needs to be installed within the following parameters.

The diagram at left shows the optimum position for gate opener arm in relation to the gate in the open and closed positions.

Be sure the position of the gate opener and brackets allows for 1" of clearance between the gate and the opener in both the open and closed position, at the same time maintaining a maximum distance of 13" from the end of the retracted opener arm to the gate bracket with the gate in the closed position.

If the gate post is larger than

6" the Post Pivot Bracket can be removed and the center hole of the Post

Bracket can be the mounting point for the gate opener.

Center hole of post bracket


Installation of the FIRST Gate Opener

IMPORTANT: Determine which side of the driveway you will mount the control box. From this point on, the gate and gate opener on the same side as the control box will be referred to as the FIRST gate and gate opener. The gate and gate opener on the opposite side of the driveway from the control box will be referred to as the SECOND gate and gate opener.

We recommend you position the opener near the centerline of the gate to keep the gate from twisting and flexing and to avoid backsplash from rain water.

The Post Bracket Assembly

The position of the post bracket assembly determines the leverage and efficiency of the opener. The post bracket assembly position also sets the clearance between the opener and the gate in the open and closed positions.

Wooden Post Metal Plate

Wooden Post Metal Plate

The post bracket works well for installations on round and square fence posts. Because the post bracket carries the entire thrust of the active opener, bolts must completely penetrate the post.

On wood posts, place a metal plate or washer (not supplied) between the nuts and the post to prevent the thrust of the opener from pulling the bolts and washers out of the wood.

The post pivot bracket may not be necessary on posts larger than 6" in diameter (see page 6). Fence posts smaller than 6" in diameter or 6" square should be made of metal instead of wood to remain stable while the opener is moving the gate.

Reinforcing Gates for the Gate Brackets

We recommend using a muffler clamp, wood, or metal, to reinforce thin-walled tube gates, or wood to reinforce panel gates as shown. These reinforcement methods will prevent damage to the opener and gate. Additional hardware may be needed depending on the installation.

Step 5

Be sure the position of the gate opener and brackets allows for 1" of clearance between the gate and the opener in both the open and closed position, while at the same time maintaining a maximum distance of 13" from the end of the retracted opener arm to the gate bracket with the gate in the closed position. This mounting position will give the opener the most efficient leverage point for operation and provides the least possible pinch area

Step 6

After verifying that you have the best position for the post pivot bracket in the open position, insert the 5 / 16 " x 1 1 / 2 " bolt through the aligned holes of the post bracket and post pivot bracket to hold it in place. Remove the clevis pin from the front mount and while

supporting the gate opener, swing the gate and gate opener to the closed position. Again, check the clearance and be sure that the gate opener is not binding at the post pivot bracket.

If you don't have the required clearance, or if the gate opener is binding on the post pivot bracket, remove the 5 / 16 " x 1 1 / 2 " bolt and readjust the post pivot bracket.

TIP: Turn the post pivot bracket over for more hole alignment options. You can also move the entire post bracket assembly to different positions on the post.

Step 2

Install the SECOND gate opener and hardware on the second gate following the same procedures as the FIRST gate opener and hardware ("Installing Post Bracket Assembly and Gate Bracket" Steps 1–10).

NOTE: The power cable for the Second Opener should be run in PVC conduit under the driveway to protect it from damage due to lawnmowers, heavy equipment, etc. (See illustration on page 6.) NEVER SPLICE opener arm power cables. This will cause performance problems and may damage the opener.


Install the Closed Position Stop Plates

The closed position stop plate is attached to the FIRST gate to help stabilize the gate leaf in the closed position. An optional low profile ground stop, when used with the closed position stop plate, provides a secure point for the SECOND gate to close against.

To further enhance the stability and security of your gate, install a Mighty Mule Automatic Gate Lock [FM143] page 26).If you will be using the Mighty Mule Gate Lock with your gate opener system, the closed position ground stop is required.

For Pull-to-Open systems, install the closed position stop plates on the inside of the gates.

IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE:

• The only wire acceptable for use with GTO products is 16 gauge stranded, low voltage, direct burial wire. This particular gauge enables the transformer to provide an adequate charge through the control board to the battery at distances up to 1000'.

• DO NOT use telephone wire or solid core wire. Unlike stranded wire, these types of wire are inadequate for use with your gate opener system.

• NEVER splice wires together. Splicing permits corrosion and seriously degrades the wire's ability to carry an adequate current.

Step 1

Make sure the power switch is OFF.

Step 2

Select the electrical outlet where you will plug the transformer. Measure the distance from this outlet to the control box following the path where the wire will be laid. After you have measured how much wire is needed, cut the wire to the appropriate length (up to 1000').

Step 3

Lay the measured length of low voltage wire in a trench following a path from the selected electrical outlet to the control box. Wires coming up from the ground should be run through PVC conduit to protect them from lawn mower blades, weedeaters, and grazing animals. Be sure to bury the wire laid in the trench.

Step 5

Strip 3 / 16 " off the ends of the low voltage wire and twist tightly. Attach these ends to the 14VAC OR SOLAR terminals located on the terminal block). Be certain not to let the exposed wires touch each other!

Insert one transformer wire into a 14VAC OR SOLAR terminal. Insert the other transformer wire into the remaining 14VAC OR SOLAR terminal.

The transformer wires can be connected to the 14VAC OR SOLAR terminals regardless of color/polarity.

Tighten set screws against exposed end of wires.

Step 6

At the AC outlet, strip 1 / 2 " of insulation from the ends of the low voltage wire. Attach these stripped ends to the transformer terminals. We suggest adding crimp on fork lugs to the end of each wire before attaching it to the transformer.

Make sure the exposed wires do not touch each other!

Push-To-Open Installation Instructions

PUSH-TO-OPEN gates open out from the property (opener arms extend to open). Push-To-Open Brackets are required for this type of installation, one for each gate [FM148] page 26. In a Push-To-Open installation, the opener is installed while the gate is in the closed position and the opener fully retracted.

Swinging gates MUST NEVER open into public access areas!

Step 1: Read "Installation of the Gate Opener" on page 7.

Step 2: Determining The Mounting Position of The Post Bracket Assembly

A. Insert the 3 / 8 " x 1 1 / 2 " bolt through the center hole of the post brackets and post pivot bracket. Secure with a 3 / 8 " washer and 3 / 8 " lock nut. DO NOT overtighten the lock nut (the post pivot bracket will have to be adjusted later). Attach post bracket assembly to the rear mount of the opener with a clevis pin and a 3 / 8 " washer. Secure the clevis pin with a hairpin clip. Attach gate bracket to the front mount of the opener with a clevis pin and a 3 / 8 " bushing. Secure the clevis pin with a hairpin clip.

B. With the gate in the closed position (up to 110º from its open position), and the opener fully retracted, adjust the post bracket assembly and gate bracket until the opener is level.

While holding the opener level, use C-clamps to temporarily keep the post bracket assembly and gate bracket in their respective positions on the fence post and gate.

IMPORTANT: Be sure the position of the gate opener and brackets allows for 1" of clearance between the gate and the opener in both the open and closed position, while at the same time maintaining a maximum distance of 13" from the end of the opener arm to the gate bracket with the gate in the open position. This mounting position will give the opener the most efficient leverage point for operation and provides the least possible pinch area.

C. After verifying that you have the best position for the post pivot bracket in the closed position, insert the 5 / 16 " x 1 1 / 2 " bolt through the aligned holes of the post bracket and post pivot bracket to hold it in place. Remove the clevis pin from the front mount and while supporting the gate opener, swing the gate and gate opener to the open position. Again, check the clearance and be sure that the gate opener is not binding at the post pivot bracket.

IMPORTANT: If you don't have the required clearance, or if the gate opener is binding, remove the 5 / 16 " x 1 1 / 2 " bolt and readjust the post pivot bracket. TIP: Turn the post pivot bracket over for more hole alignment options.

Solar Panel Instructions


It will damage the control board!

IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE:

• The only wire acceptable for use with GTO products is 16 gauge stranded, low voltage, PVC sheathed wire. This particular gauge enables the solar panel to provide an adequate charge through the control board to the battery at distances up to 250'.

• DO NOT use telephone wire or solid core wire. Unlike stranded wire, these types of wire are inadequate for use with your gate opener system.

Step 1

Make sure the power switch is OFF.

ON/OFF

Switch

Step 2

Strip 3/16" off the ends of the low voltage wire and twist tightly. Attach these ends to the 14VAC OR SOLAR terminals located on the terminal block. Be certain not to let the exposed wires touch each other!
