48V Wireless Keypad
Power Supply

Installation Guide

Introduction
The 48V Wireless Keypad Power Supply enables Control4
wireless keypads—typically used with standard 110V or 240VAC
power—to be powered using Class 2 low-voltage power. Multiple
keypads can be powered over common low-voltage wiring, such
as 16/2 or CAT5e Ethernet cable.

Installing the power supply

1 Ensure that the location and intended use meet the following
criteria:
• Install in accordance with all national and local electrical
codes.
• NEC Code dictates that Class 1 (high voltage) and Class
2 (low voltage) powered devices cannot be installed
together in the same junction box. There are some
exceptions if this type of installation is required. Refer to
the current NEC documentation for additional information
or consult your building inspector.
Important! Ensure the power supply is not plugged into
a live AC power outlet until all wiring connections have
been made between the power supply and the wireless
keypads.
2 Connect the positive (+) and ground (-) leads from the
power supply to the appropriate leads on the multi-button
keypads (either directly or over an appropriate low voltage
cable).
3 Connect the red 48VDC (+) lead from the power supply
output to the Line In (black or brown) lead/terminal of the
keypad.
