Aiphone Audio Not Working? A Troubleshooting Guide
An Aiphone intercom system is a critical tool for communication and security, but its purpose is defeated when the audio fails. Whether you can't hear your visitor, they can't hear you, or there's no sound at all, this guide will walk you through the essential steps to diagnose and resolve the problem.
We will cover the most common causes, from simple user settings to wiring checks, helping you restore two-way communication on your Aiphone system.
Step 1: Check Basic Controls and Settings
Before assuming a major fault, it's important to check the simple operational settings on your Aiphone stations. These are often the cause of audio issues.
- Volume Adjustment: Locate the volume controls on your indoor master station. There are often separate controls for call tone and communication volume. Ensure the communication volume is turned up to an audible level. Some door stations also have a small volume adjustment screw.
- Privacy/Mute Button: Many Aiphone master stations have a "privacy" or "mute" feature, often indicated by an LED. When activated, this function can disable the microphone or speaker. Make sure this feature is turned off.
- "Do Not Disturb" Mode: Check if your system has a "Do Not Disturb" (DND) mode that might be silencing all audio functions. Disable this mode if it is active.
Step 2: Power Cycle the System
A simple restart can often resolve temporary electronic glitches. This process, known as a power cycle, will reboot the internal software of your intercom system.
- Locate the Power Supply: Find the power supply unit for your Aiphone system. This is often a plug-in transformer or a dedicated power unit in a utility closet.
- Disconnect Power: Unplug the power supply from the mains outlet or switch off the corresponding circuit breaker.
- Wait: Leave the system powered off for at least 60 seconds. This allows any residual power to dissipate completely.
- Reconnect Power: Plug the power supply back in or switch the circuit breaker on. Allow a few minutes for the system to fully reboot before testing the audio.
Step 3: Inspect the System Wiring
Faulty wiring is a very common culprit for audio failures in wired intercom systems like Aiphone. A loose or damaged connection can interrupt the audio signal.
Important: For safety, it is highly recommended to power down the system before inspecting any wiring.
- Check the Master Station: Carefully remove the master station from its wall mount. Check that all wires are securely seated in their respective terminals on the back of the unit. Gently tug on each wire to ensure it is making a firm connection.
- Check the Door Station: Similarly, inspect the wiring on the back of the outdoor door station. Look for any signs of corrosion on the terminals, especially as this unit is exposed to the elements.
- Look for Damage: Visually inspect the length of the cable between the stations if possible, looking for any obvious signs of damage, such as cuts or abrasions.
Step 4: Test for Hardware Issues
If the settings and wiring appear to be correct, you may have an issue with the microphone or speaker in one of the units.
- Test One-Way Communication: Can you hear the visitor but they can't hear you? This points to a problem with the master station's microphone or the door station's speaker.
- Test the Other Way: Can the visitor hear you but you can't hear them? This suggests an issue with the door station's microphone or the master station's speaker.
- Use the Monitor Function: If your system has a "monitor" button, press it. This should allow you to hear audio from the door station without a call being initiated. If you hear background noise, it confirms the door station's microphone is working.
If you have performed all these checks and the audio is still not working, it may indicate a component failure that requires professional attention. Contact an authorised Aiphone dealer or a qualified technician for further assistance.
