Installation Manual
Step 2: To hard-wire the keypad - 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 pole and the
other to the NEGATIVE 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: With the power to the opener turned OFF.
Remove opener control board cover and feed enough of the low voltage keypad wire through a strain relief to
reach the gate opener control board terminals.
Step 5: Attach the wires from the keypad to the opener control board terminal blocks as shown below.
Step 6: Replace the control board cover and turn the power switch ON. Test the keypad by entering 1 2 3 4.
Step 7: Program your ‘Personal Master Code’ and any additional entry codes (for a total of 25 entry codes)
you wish. See Programming the Keypad section.
