Thank you for purchasing the Mighty Mule Wireless Gate Entry Intercom.
Please read the directions carefully and completely before installing.
SAFETY NOTE: Never install the keypad portion of this
unit where a person can reach through the gate to
activate it, or where a person can touch the gate while
activating the keypad. The recommended minimum
distance between the gate and keypad is 10 ft.
IMPORTANT: Allow the

Base Unit
Wireless Gate Entry Intercom

The INTERCOM has two separate units. The KEYPAD (outside unit) should be mounted outside the gate allowing the driver of the
vehicle approaching the property to press the CALL button from their vehicle. The BASE (inside unit), with it’s rechargeable battery,
can be plugged into any 110 Volt AC outlet for use while charging. It can also be disconnected from the charger allowing it to go any
where within range for convenience. Up to three additional BASES can be added for convenience in different locations throughout
the house.
When someone without an access code approaches the gate, they can press the CALL button on the keypad which will ring the
BASE unit inside the house. To answer the CALL, the person inside presses and holds the ANSWER button to talk to the person
at the gate, releasing the ANSWER button to listen. To allow the person calling to open the gate, the GRANT PERMISSION button
must be pressed. Then the person at the gate can press any number key on the KEYPAD to open the gate. The “END CALL” button
terminates the calls and the “ON/OFF” switch can be used to conserve power when using unit on battery.
Up to 25 different personal entry codes may be programmed into the KEYPAD, allowing you to give different temporary and
permanent entry codes to different users. For example, you can give a delivery person their own temporary entry code, which you
can easily change after he has made the delivery. This will prevent him from being able to regain access, while still allowing those to
whom you gave permanent entry codes full access.
After entering a valid code, pressing any key on the KEYPAD while the gate is opening will stop the gate; pressing any key while
the gate is stopped will cause the gate to reverse direction. The KEYPAD will not affect the auto-close setting of your gate opener
system.
The KEYPAD number pad will light up and the unit will beep at the press of any key. The KEYPAD memory will recognize your
entry code in a string of up to 20 digits. If it nds the correct sequence, it will activate the gate opener. As a security feature, the
keypad will shut down for 40 seconds if it does not nd the correct code sequence within a 20 digit string. This will discourage an
unauthorized person from trying to use random numbers to access your property.
Your entry codes will remain stored in memory even when the batteries go dead. The KEYPAD will remember your entry codes as
long as you don’t press the RESET button.
Features of the Intercom/Keypad
IMPORTANT: In areas of high radio frequency (RF) interference, the KEYPAD may need to be connected (hard wired) directly to the
gate opener using 16 gauge (AWG) stranded, direct burial, low voltage wire (part no. RB509 not included).
Also in areas of high radio frequency (RF) interference, the BASE unit may not communicate with the KEYPAD and will require
extending the antenna from the KEYPAD closer to the house co-ax cable (RG59 or RG6 which is not included). See page 8 for
details.

Wireless Installation of the Keypad
NOTE: For wireless applications, the distance from the keypad to the opener’s receiver should not exceed 50 ft. Always test the
keypad range before permanently mounting it.
Learning an MM136 to an MM371, MM372, MM571 or MM572
Automatic Gate Opener
1. With the power on for your control box, press and hold the
gate opener's middle orange (S3) button ( ) located on the
control board until you hear a beep, then release it.
2. Next, enter the master code or an entry code, but continue
pressing the last digit until the control board beeps again. Any
programmed code will work.
a. Example: Press 1, 2, 3, and then hold down 4 until the
control board beeps.
3. Test the keypad code by pressing any single digit if the
keypad has not yet timed out.
4. Once functionality is veried, you can mount the keypad cover
with the screws provided and slide the keypad on the cover
using the small screws to secure it.
NOTE: If you hear three short beeps in succession, the
programming mode has timed out and you will need to repeat
steps 1 and 2.
To forget the MM136, simply follow steps 1 and 2 above then test
the keypad to verify that it no longer activates the Operator.
Learning an MM136 to an MM271 or MM272 Automatic Gate Opener (A dip-switch type
transmitter may be required)
1. Use the On/Off switch on the control box to power the system down.
2. Enter the master code or an entry code but continue pressing the last digit. Any programmed code will work.
a. Example: Press 1, 2, 3, and then hold down 4.
3. While still holding the last digit of the code, power the system on with the on/off switch.
4. After the startup beep, there will be a long silence for about 10 seconds, followed by a continuous beep. Keep holding the last
digit of the code on the keypad.
5. Release the button on the keypad.
6. Test the keypad code by pressing any single digit if the keypad has not yet timed out.
7. Once functionality is veried, you can mount the keypad cover with the screws provided and slide the keypad on the cover using
the small screws to secure it.
To forget the MM136, simply follow steps 1 through 5 above then test the keypad to verify that it no longer activates the Operator.
Note for MM271: The gate must be in the closed position with the arm extended to delete a PIN code. The gate can be in any
position to add a PIN code.
If programming fails on an MM271/MM272: You must use a dip-switch type transmitter (FM134/FM135, MM3BT, RB741/RB742)
to program the keypad. Simply match the dip-switch patterns between the transmitter and MM136 then learn the transmitter to the
system. Contact Tech Support for a complimentary dip-switch type transmitter to program the MM136 if you do not have one.
Alternatively, you can set the keypad DIP switches to match your entry transmitter’s DIP switches. See the following page for
instructions.

Wired Installation of the Keypad
NOTE: If you also plan to power the keypad with the gate opener’s power source, run two pairs of wires as described below. One
pair to hard-wire the keypad and the other pair to connect the keypad to the gate opener’s battery.
Step 1: Turn the gate opener’s power switch OFF. Use 16 gauge, stranded, direct burial low voltage wire (part no. RB509) to
connect the keypad to the opener control board. Run wire through PVC pipe from the ground to keypad and from the ground to the
opener control board to protect the wire from lawn mowers or grazing animals.
Determine how the wire will enter the keypad (i.e. from the back through a hole drilled in the mounting post or running the wire on
the surface of the post). Remove the small rectangular knock-out on the back of the keypad cover and pull the wire into the cover.
Then mount the cover to the post using the screws provided.
Step 2: For hard-wired communication between the keypad and gate opener, using 16 gauge (AWG) stranded, direct burial, low
voltage wire (part no. RB509) strip the wires back 3/16” and attach the wires to the terminal block marked RELAY OUTPUT on
the keypad control board as shown to the right. Connect the other end to the opener’s control board as shown in Control Board
Connections section below.
To wire the power supply to the keypad, attach the wires to the AC/DC POWER IN terminal on the keypad control board as shown to the right.
Connect the other end to the opener’s battery - one end to the POSITIVE (RED) pole and the other to the NEGATIVE (BLACK) pole.
NOTE: For a hard-wired application the jumper between the two terminals on the keypad control board must be connected (ON) as
shown. This will disable the 318 MHz RF transmitter.
Step 3: Slide the keypad into the cover and secure with the small screws provided.
Step 4: Turn the power to the opener OFF. Remove the opener control board cover and feed enough of the low voltage wire from
the keypad through a strain relief to reach the gate opener control board terminals.

Intercom Base Unit Installation
Find a convenient location near an approved outlet to mount
or place the intercom. Plug the transformer into the AC outlet
and connect it to the intercom’s power jack marked DC 9V.
If you are mounting the intercom on the wall, use the
template on the last page of this manual to place screws.
The intercom can be disconnected from the transformer
and used as a battery powered unit. It can be moved to any
convenient location, i.e. bedroom, patio, or garden area.
IMPORTANT: When the Intercom unit is ON it is in the
receive mode. When plugged into the transformer it is
constantly charging the battery. The battery will last
approximately four (4) hours when unplugged from the
transformer. You can turn the unit OFF to conserve battery
power but it will not receive a signal when OFF.
Remove the battery access cover using a small
phillips head screwdriver. Plug the rechargeable
Ni-MH battery into the receptacle inside the battery
compartment. See diagram to the right. When this is
done, replace the battery access cover.

Intercom ID Codes
The Base and Keypad that came in this kit are programmed at the factory to communicate with each other, and do not need the ID
Codes programmed. This Base is the MASTER or #1 unit.
If you have purchased additional Base units to enhance your
system, each additional unit’s ID Code must be programmed into
the Keypad so they can communicate. Follow the steps below to
set the ID codes.
15
Test the System
IMPORTANT: The Base unit and the Keypad can not be within 30 feet of each other when operating. If units are closer than 30
feet the signal will be inconsistent as well as emit speaker feed back. Also, multiple Base units must be no closer than 10 feet
from each other to prevent interference.
Have someone press the CALL button on the keypad at the gate. When the base unit inside the house rings, press the ANSWER
button and talk to the person at the gate to check the connection and range. Then press the GRANT PERMISSION button and
have the person at the gate press any key on the keypad to activate the gate.
Troubleshooting
Make sure all connections are secure and correct.
Other electronic devices in the same area may interfere with the factory ID code. If the system does not communicate at all,
reset the intercom/keypad ID code as follows.
RESET ID: This will require two (2) people.
1. Open the keypad and locate the “ID SET” button above the batteries.
2. Locate the “ID SET” button on the bottom of the intercom base unit.
3. Make sure the “antenna-to-antenna” distance between the keypad and the base unit is at least 30 feet.
4. Reset the MASTER Intercom base unit’s ID Code.
Batteries must be installed and the units turned ON.
A. Press the “ID SET” button on the Keypad until you hear a beep, then release. This erases all stored ID Codes.
B. Press the “ID SET” button on the MASTER Intercom for approximately 2 seconds then release. You will hear ONE beep from
the Intercom and TWO from the Keypad, which means the ID Codes are reset.
C. Test the system by pressing the CALL button on the Keypad to see if the Intercom receives the signal.
NOTE: If the system is now working you will need to reset any additional Intercom you have installed. See “Adding Additional Intercoms”.
IMPORTANT: Base units must be no closer than 10 feet from each other to prevent interference.
