How to Fix Panel Communication Failure on the GC3

Summary: A communication failure message indicates your system is not connecting with the Alarm Response Center. This prevents alarm signals from being received. This guide explains common causes and provides step-by-step solutions to restore communication. If the issue persists, our Support Representatives are available to assist you.

Common Causes and Solutions

1. Has Your Wi-Fi Name or Password Changed?

If you recently updated your Wi-Fi name, password, or replaced your router, follow these steps to reconnect your system to Wi-Fi.

2. Power Outage

Ensure your system has power. Communication will resume once power is restored.
If the panel battery is weak due to a recent outage, allow up to 24 hours for recharging.

3. Loss of Connection to Power Source

Check that the plug is securely connected to the outlet.
Verify the outlet is providing power by plugging in another device.

4. 3G Cellular Service Expired

3G technology was phased out in 2022. Your panel may need a cellular module upgrade.
To schedule an upgrade, text 469.513.8685.
With Wi-Fi connected, signals can still be received by Brinks Home.

5. Local Cell Provider Outage

A temporary cell service interruption in your area may impact system communication. Ensure your Wi-Fi is connected as a backup.

6. Signal Interference

Relocate large metal objects or appliances emitting radio frequencies away from the panel.
Place the system near an exterior wall above ground (not in a basement).

7. System Malfunction

To resolve a system malfunction, perform a power cycle:

Power down the panel and disconnect the module.
Wait 2 minutes, then reconnect power.

8. Interruption to Landline Phone Service

Check for a phone service outage in your area.
Ensure your phone line is connected to the system.
Switching providers or disconnecting landline service may require upgrading to cellular communication. Text 469.513.8685 for assistance.
VoIP and Digital Voice Over Cable may not be compatible with your panel. Consider switching to a supported service.
