How to Fix Your Intercom System: A Step-by-Step Guide
Intercom systems are essential for security and communication. When they malfunction, it can be frustrating. This guide will help you troubleshoot and fix common intercom issues.
Step 1: Check the Outside Station
If your intercom doesn’t work, the outside station is likely faulty. Open the station and inspect the PCB. Ensure it’s clean and free of insect or water damage. If you find visible damage, replace the outside unit. If there is no visible damage, proceed to the next step.
Step 2: Refer to the Intercom Manual
Find the intercom manual to understand the power connections. Usually, the indoor monitor or handset connects to the power supply. The outside unit typically connects to the indoor station. Some intercoms, like Kocom, have power lead connected to the handset. Others, like Farfisa and Jade, have power supplies somewhere under the house, feeding both ends. Centurion intercoms can be fed from any end.
Step 3: Test Direct Connections
Identify the power source. Connect both units directly to each other or to the power source. This step eliminates wiring issues, which can occur over long distances. If all units work fine when connected directly, you have a wiring fault. Check all wire cores and see if any spares can replace the faulty one. Ideally, replace the faulty wire. Use gel-filled underground wire for new insulation.
Step 4: Replace Units if Needed
If directly connected units don’t work properly, and there is no visible damage, try replacing the outdoor station first. If the issue persists, replace the indoor unit.
Step 5: Inspect Plug-In Connections
Check all plug-in connections of both units. Videx audio intercoms have connections on the handset. These connections can sometimes malfunction. Ensure they are secure and functioning properly.
Step 6: Replace Damaged Speakers or Microphones
Humidity can damage the speaker or microphone of the outside unit. Replace them with components of the same Ohm rating. This simple fix can restore functionality.
Step 7: Replace Worn-Out Keypads
Old Videx keypads often have worn-out buttons. Replace the keypad to resolve this issue. It’s a straightforward solution that can significantly improve performance.
Step 8: Clean Corroded Call Buttons
Farfisa call button springs sometimes corrode, causing poor contact. Disassemble the unit and clean the corrosion. This maintenance step can restore proper function.
Step 9: Check the Power Supply
If the intercom is completely dead, find and check the power supply. Replace it if it’s faulty. A functioning power supply is crucial for the intercom system.
Call a Specialist
If these steps don’t resolve the issue, consider calling a professional. Sesame Gate Automation specialists can fix your intercom or access control devices. They have the expertise to diagnose and repair complex problems.
Conclusion
Fixing an intercom system involves several steps. Start by inspecting the outside station. Refer to the manual for power connections. Test direct connections to rule out wiring issues. Replace damaged units and components as needed. Finally, check the power supply. For persistent issues, contact a specialist. Following this guide will help you restore your intercom system efficiently.
