Setup and Installation
1. Mounting Location
Select a suitable outdoor location near the entry point, ensuring it is within reach of the wiring for the master intercom. The unit is weather-resistant, but positioning it under an overhang can provide additional protection from direct heavy rain.
2. Surface Mounting
- Carefully remove the front cover of the LE-D unit to expose the mounting holes and wiring terminals.
- Position the backplate of the LE-D unit against the wall or single-gang box where it will be mounted. Mark the positions for the mounting screws.
- Drill pilot holes if necessary, then secure the backplate to the surface using the provided mounting hardware. Ensure the unit is level.
3. Wiring Connections
Refer to the wiring diagram below and the instructions provided with your Aiphone LEF or LEM Series master intercom for specific wiring details. The LE-D unit typically requires two wires for audio communication and power from the master intercom.

This view is crucial for understanding how to connect the unit.
- Connect the two wires from the master intercom to the designated terminals on the LE-D unit. Polarity may be important; consult your master intercom manual.
- Ensure all connections are secure and insulated to prevent short circuits.
4. Final Assembly
Once wiring is complete, carefully reattach the front cover of the LE-D unit. Ensure it snaps or screws into place securely to maintain its weather resistance.
Operating Instructions
Initiating a Call
When a visitor presses the call button on the LE-D door station, a chime will sound on the connected Aiphone LEF or LEM Series master intercom. This indicates a visitor is at the door.
Two-Way Communication
To communicate with the visitor, the occupant must activate the talk function on the master intercom. Audio communication is then established between the door station and the master intercom.
Maintenance
- Cleaning: Periodically wipe the exterior of the door station with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Inspection: Regularly check the unit for any signs of damage or loose connections. Ensure the front cover is securely fastened.
- Environmental Protection: While weather-resistant, extreme conditions can affect performance. Ensure proper drainage around the unit if installed in an area prone to standing water.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No chime at master intercom when call button is pressed. | Loose or incorrect wiring; faulty master intercom; faulty door station button. | Check all wiring connections at both the door station and master intercom. Ensure master intercom is powered on and functioning. Test the call button for proper mechanical action. |
| No audio or poor audio quality. | Loose or incorrect wiring; microphone/speaker obstruction; faulty components. | Verify wiring connections. Ensure microphone and speaker grilles are clear of debris. Test with another master intercom if possible. |
| Door station appears damaged. | Physical impact; environmental exposure. | Inspect for cracks or breaks. If functionality is affected, replacement may be necessary. |
If troubleshooting steps do not resolve the issue, contact Aiphone customer support or a qualified technician.
