3.4. Wiring Diagram
Proper wiring is crucial for the system's functionality. The lobby unit requires a DC12V, 1.5Amp power source and provides power to the handsets. The system uses a common 3-wire connection plus individual 1-wire for the lobby unit, and 6 wires for the handset (4 to door station, 2 to door lock).

4. Operating Instructions
4.1. Visitor Calling a Resident
- The visitor presses the corresponding apartment button on the DR-6UM lobby unit.
- The DP-SS handset in the selected apartment will ring.
- The resident picks up the handset to establish two-way audio communication with the visitor.
4.2. Resident Opening the Door
- During an active call with a visitor, the resident can press the door release button on their DP-SS handset.
- This action will activate the connected electric door strike (not included), allowing the visitor to enter.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the surfaces of the lobby unit and handsets. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Connection Checks: Periodically inspect all wiring connections to ensure they are secure and free from corrosion or damage. Loose connections can lead to intermittent operation or system failure.
- Environmental Conditions: Ensure the units are not exposed to extreme temperatures, direct sunlight for prolonged periods, or excessive moisture, which can affect performance and lifespan. The lobby unit is designed for outdoor use but should be protected from direct heavy rain if possible.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No audio from handset or lobby unit. | Loose or incorrect wiring; power supply issue; faulty unit. | Check all wiring connections according to the diagram (Image 3.6). Verify the 12V power supply is active and connected. If issues persist, contact support. |
| Handset does not ring when button is pressed. | Incorrect wiring for specific apartment; faulty button on lobby unit; handset power issue. | Confirm the correct apartment button is pressed. Check the individual wiring for that specific handset. Ensure the handset is receiving power from the lobby unit. |
| Door release function not working. | Electric door strike not connected or powered; incorrect wiring to door lock terminals; faulty handset button. | Verify that an electric door strike is properly installed and has its own power source (if required). Check the 2-wire connection from the handset to the door lock. |
| Intermittent communication. | Loose connections; interference; damaged wiring. | Secure all wiring connections. Ensure wiring is not running parallel to high-voltage lines. Inspect cables for any physical damage. |
