How to Troubleshoot Poor or No Signal Strength IQ Panel 2 and 4

If your Qolsys panel is reporting low/no signal strength or you are seeing a Dual-Path Communication Failure - Cellular trouble condition in, the below steps should help to resolve the issue.

What is recommended is a full power cycle of the system, leaving the system completely off for at least two minutes before powering the system back on. This will give the panel a chance to reconnect to the nearest cellular tower and typically fixes cellular connection errors that are not hardware related.

To do so:

  1. Navigate to Settings > Advanced Settings > Enter Installer Code > Power Down to turn off the Qolsys panel.
  2. Unplug the power supply from the wall outlet
  3. Open the panel and disconnect the internal battery.
  4. Leave the panel powered down for at least 2 minutes.
  5. Plug the battery back in, close up the panel and reconnect the power supply
  6. Press the button on the side of the panel for about 2 seconds to turn it back on.
  7. Once the panel has rebooted, wait about 5 minutes, then run a cell test and check signal strength.
    • To run a cell test, navigate to Settings > Advanced Settings > Enter Installer Code > System Tests > Cellular Tests.
