Before referring to the commax dp-ra01 installation manual

The Commax DP-RA01 is an audio doorphone room station typically installed as part of a single-house intercom system. It is designed for surface mounting and operates on a universal power source of AC 100-240V.  Installation Steps 

Mount the Bracket: Secure the included wall-mounting bracket to a flat surface using the provided screws. Wiring Connections:

Door Station: Connect 2 wires from the door station to the designated terminals on the DP-RA01. This connection is typically non-polarity, meaning the order of the two wires does not matter.

Door Release: If installing an electric door strike, connect 2 additional wires from the DP-RA01 to the door lock. Note that the door release may require its own separate power source depending on the lock type.

Attach the Handset: Align the grooves on the back of the DP-RA01 unit with the hooks on the wall bracket. Slide the unit down firmly until it locks into place.

Power Up: Plug the unit into a standard AC outlet. Avoid handling the power cable with wet hands to prevent electric shock.  Compatible Equipment
