  • Touch “Upgrade Software”.
  • Touch “Patch Tag” and enter: iqpanel4.5.1 then touch “OK”
  • Touch “Upgrade Using Network”. If the panel is connected to WIFI, the system will begin downloading the update. The update will be installed when the download completes.

When the panel returns to the home screen and the Green LEDs are lit, the process is complete.

Instructions for Updating the Qolsys IQ Panel 4 Via Access Point

For customers who cannot update using WIFI, follow these steps to update using a phone, tablet, or computer:
  1. Download and save the file required for the update to the device (phone, tablet, or computer). The latest update file is usually linked via the green button above. If you need to install any of the prerequisite versions those files are linked below. When you are taken to the Dropbox page, choose the Download button. If you are prompted to sign up or sign in to Dropbox. Click the link at the bottom of this prompt that says, "Continue with download only." This will download the entire file folder to your device, rather than the individually listed files. This is what you want.
  2. On the IQ Panel, go to Settings > Advanced Settings > Upgrade Software > "Upgrade Using Access Point".
  3. A QR Code will be displayed on the IQ Panel 4, scan it with your phone or tablet. If you are using a computer, then connect to the panel's access point using the SSID and Password provided on the panel screen.
  4. Press "Start" to begin the local server session, then from your device scan the second QR code provided by the IQ Panel 4, or if that's not an option, navigate to the "https" URL shown on the panel's screen.
  5. Follow the prompts on your phone, tablet, or device screen to select the correct files and transfer them to the panel.
  6. Once the files have been loaded to the IQ Panel 4, it should begin the update process.
