IF USING THE KEYPAD WITH A MECHANICALLY OPERATED DOOR OR
GATE, MOUNT THE KEYPAD AT LEAST 5’ (15m) FROM THE DOOR OR
GATE TO PREVENT USERS FROM BEING CRUSHED OR PINNED.
FAILURE TO DO SO MAY RESULT IN SERIOUS INJURY OR DEATH.
1. Always disconnect power before servicing the keypad.
2. The keypad must be properly grounded. Use a minimum 22AWG wire connected to the Uninsulated
Chassis Ground wire. Failure to do so may damage the keypad.
3. All wiring and programming should be done by a professional installer to reduce the risk of
improper installation.
4. Basic keypad functions are located on page 16 of this manual. Be sure to store this manual in a safe
place for future reference.
5. If using VAC, use the Green Common Ground wire for all sensor input.
* Chassis Ground: Connect a continuous wire from the Uninsulated Chassis Ground wire to a
grounding point to avoid damage from static discharge. A good grounding point could include a
grounded metal conduit, a cold water pipe, or a grounding rod. Use 18AWG wire for earth ground for
best results. Wire used must be at least 22AWG.

1. Find a suitable location to mount the keypad. Do not install where it will be too high or too low for most
users to operate the keypad.
2. Using the included Torx wrench, unscrew the security screw located on at the top and bottom of the face
of the keypad to uninstall the mounting bracket.
3. Carefully remove the keypad from the mounting bracket.
4. Drill holes in the 4 designated mounting points located on the mounting bracket. If needed, use the
included mounting template.
5. Using the 4 included mounting screws, secure the mounting bracket to a wall or other mounting surface.
If mounting to brick or drywall, it may be necessary to use the included screw anchors.
6. If the installation is using surface wiring, mount the keypad to a single-gang box using the 2 single-gang
box mounting points.
7. Connect each of the wires that will be used to operate the keypad according to the wiring diagram on
page 4.
8. Reattach the keypad to the mounting bracket.
9. Use the included Torx wrench to tighten the security screws and secure the keypad to the bracket.
