Before installing the keypad, the unit must be partially 
disassembled to access the mounting plate. The keypad’s bezel 
can be exchanged for a different color when the keypad is apart.

Opening the Keypad
The keypad assembly is secured with two tamper-resistant screws 
that are hidden behind the keypad’s faceplate. Refer to Figure 3 for 
disassembly details.

❑ Use a small fl at blade screwdriver to pry off the keypad’s 

faceplate.

❑  Use the special allen wrench (supplied) to remove the two 

tamper-resistant screws.

The colored keypad bezels snap onto the keypad assembly. Refer

hold the bezel to the keypad assembly.

❑  Remove the bezel from the keypad assembly.

❑  Choose the proper color bezel for the installation and snap 

it onto the keypad assembly.

Install the Electrical Box and Mounting Plate
The keypad is designed to fi t into a standard single-gang electrical 
box. Select a location near the controlled door and choose a 
convenient height for the keypad. Be sure there is good wiring 
accessibility for the unit’s power and the output to the door strike 
or access device.

❑  Install the electrical box in the wall.

❑  Screw the mounting plate onto the electrical box (see

the keypad, remove Jumper JP1 (place the jumper block on 
one pin to save the jumper).
