When a GSM intercom picks up electronic noise, it may exhibit the following symptoms:
Static, buzzing, or crackling sounds during conversations.
Random call disconnections or failure to establish calls.
Delayed or failed call connections.
Unintended background noises or echoing of the user's voice.
No intercom communication in one or both directions.
If you experience any of these issues, refer to the possible solutions below to mitigate electronic noise interference.
Ensure Proper Earthing
The gate motor should be properly earthed according to the model’s installation manual.
Earth the charger or switch-mode power supply to a properly bonded earth from the AC mains supply:
Connect Earth to G-Speak GND:
Use Shielded Cabling
Utilize screened cables to minimize external interference:
Install a Noise Capacitor
Fit a noise capacitor between the power supply’s earth and COM on the gate motor to eliminate electrical noise.
Reposition Wiring
Move gate station wires away from any high-voltage cables to prevent signal interference.
By following these troubleshooting steps, you can significantly reduce or eliminate electronic noise interference, ensuring clear and reliable communication through your GSM intercom.
