PG9922—Resolving a Malfunction
Resolving Errors on a New Device:
If this error occurs on a newly installed device, it is usually an indication that the sensor is too far from the panel to maintain a signal. Determine whether you are able to move the sensor closer to the panel, or if a signal extender may be your best option. You can test if this will resolve the issue by bringing the sensor closer to the panel.
