Wired Installation Of The Keypad - Mighty Mule MM136 Installation Instructions Manual

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 .
Knock-out
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 .
