Warnings and considerations
Important: Using this product in a manner other than outlined in
this document voids your warranty. Further, Control4 is not liable
for any damage incurred with the misuse of this product. See
“Troubleshooting.”
Important: Do not use a power screwdriver to install this device. If you
do, you may overtighten the screws and strip them. Also, overtightening
the screws may interfere with proper button operation.
Important: This is an electronic device with intricate components.
Handle and install with care!
Caution! Do not exceed the number of keypads per power supply as
indicated in the Keypad Bus Wiring Guide. Exceeding the maximum
number of keypads will result in overheating the wires and/or failed
devices.
Installation instructions
Caution! When wiring the keypad, make sure that either:
• The Bus Power Supply is not powered on.
- OR -
• The pluggable connector is disconnected from the Bus Power
Supply.

individual wires, and then wire into the pluggable terminal block.

Tip: If you are using a Control4 push-on (screwless) faceplate in a
multi-gang installation, attach the black faceplate subplate to all of
the devices that will be installed into the wallbox before attaching the
devices to the wallbox. This will help ensure that all devices are properly
aligned and on the same plane after installation.
3 Fit the wires back into the wallbox.
4 Align the keypad to the wallbox (the model number label should be at the
bottom), then fasten it with the included screws.
Important: Tighten the screws until the back side of the yoke plate is
even with the wall surface, but no further. Overtightening can warp the
keypad and cause it to malfunction.
5 Install the top actuator bar, bottom sensor bar, and buttons following the
instructions in the Keypad Buttons Installation Guide (
ctrl4.co/butn
).
6 Install the Control4 faceplate following the instructions in the Faceplate
Installation Guide or attach a standard Decora-style or square faceplate.
7 Ensure that the Bus Power Supply is installed correctly and powered on. For
instructions, see the Bus Power Supply, 48V Installation Guide
(

).
