What to Do if the GC3 is Not Responding

If your GC3/GC3e panel is not responding, you will need to power cycle the panel.


  1. Disconnect AC power from the outlet. If secured in place by a zip tie, you will need to remove this first.

  9. After reconnecting the battery, return the panel to its originally mounted position, replace the screw to secure the panel to the backplate, then return AC power to the device and secure with a new zip tie.

The system will reboot, at which point touchscreen responsiveness is expected to return.
