Common Causes and Solutions

1. Power Outage

If household power was out, wait for restoration; your panel reconnects automatically.
If panel battery is low after an outage, allow up to 24 hours to recharge fully.

2. Loss of Connection to Power Source

Verify the AC adapter is firmly plugged into both the outlet and panel.
Test the outlet with another device to confirm it is supplying power.

3. Local Cell Provider Outage

Temporary cell network interruptions can block panel communications. Ensure your Wi-Fi backup is connected to maintain service during cellular outages.

4. Signal Interference

Move large metal objects or RF-emitting appliances away from your panel.
Position the panel near an exterior wall, above ground level, and not inside closets or basements.

5. System Malfunction

If the panel software or module is unresponsive, perform a power cycle:

Completely power down the panel and disconnect the communication module.
Wait 2 minutes before restoring power to the panel and module.
Place your system in Test Mode to avoid false alarms, then test communication  Test Mode Instructions.

6. Interruption to Landline Phone Service

Check for phone service outages in your area.
If you’ve switched providers, ensure the landline is correctly wired to your panel.
