On the rear PCB of the DP-RA01, you’ll find a small bank of DIP switches (usually 4 positions). These set the monitor address for apartment buildings.
For single-family homes (1-door 1-monitor): Set all DIP switches to OFF.
Do not start installation without these:
Remove the DP-RA01 from its backplate by gently prying the bottom edge. On the rear of the PCB, you will see a terminal block with 4-6 screws labeled. According to the Commax DP-RA01 installation manual, the critical terminals are:
| Terminal | Standard Function | Wire Color (Common Practice) | | :--- | :--- | :--- | | 1 (or +12V) | Positive power input | Red | | 2 (or GND) | Common ground / negative | Black | | 3 (or AUDIO) | Audio signal from door unit | White or Yellow | | 4 (or CALL / TALK) | Call button signal / voice switch | Blue or Green | | 5 & 6 | Secondary door release (rarely used) | Optional |
⚠️ Critical Warning: The DP-RA01 is polarity sensitive. Swapping terminals 1 and 2 will permanently damage the unit.

Setting Up Your Commax DP-RA01: A Simplified Installation Guide
Adding a reliable intercom like the Commax DP-RA01 is a smart move for home security and convenience. This handset-type audio door phone is known for its straightforward 2-wire setup and sturdy design.
If you’ve recently picked one up or found an old unit without the manual, this guide breaks down the essential installation steps to get your system up and running. 1. What’s in the Box? Before starting, ensure you have the primary components:
DP-RA01 Master Handset: The indoor unit with the receiver and door release button.
Wall Mounting Bracket: The metal or plastic plate that secures the handset to your wall.
Mounting Screws: Specifically designed for the bracket and handset. 2. Pre-Installation Safety
Intercom installation involves electrical components. Always follow these safety basics:
Power Down: Ensure the power source (AC 100-240V) is turned off at the breaker before touching any wires. Commax DP-RA01 Installation Manual — Detailed Guide Step
Avoid Moisture: Do not install the unit in areas exposed to direct rain or high humidity to prevent short circuits.
Check Distance: Ensure your wiring doesn't exceed 100m for 0.65Ø wire or 150m for 0.8Ø wire to maintain clear audio quality. 3. Wiring and Connections
The DP-RA01 is prized for its non-polarity 2-wire system, meaning you don't have to worry about "positive" or "negative" when connecting the door station.
Door Station to Handset: Connect two wires from the outdoor door station (such as the DR-201D) to the corresponding terminals on the back of the DP-RA01.
Door Release (Electric Lock): If you are using an electric door strike, connect it using an additional 2-wire path. Note that the power for the lock often requires its own dedicated 12V DC power source depending on your specific lock model.
Power Supply: Plug the DP-RA01 into a standard AC outlet (100-240V). 4. Mounting the Unit
Fix the Bracket: Screw the mounting bracket firmly to the wall at a comfortable height (usually around 145cm from the floor).
Attach the Handset: Align the grooves on the back of the DP-RA01 with the hooks on the bracket. Slide the unit down until it clicks securely into place. 5. Testing Your System Once everything is connected and powered on:
Test the Call: Have someone press the button on the outdoor station. You should hear a clear chime from the handset.
Check the Audio: Lift the handset and verify you can hear the visitor clearly and they can hear you.
Test Door Release: Press the key-shaped button on the handset to ensure the electric lock triggers correctly. Troubleshooting Tips COMMAX DP-SS Intercom Audio Phone User Manual
