TX-E721—Resolving a Malfunction


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 or the device is bad. 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.

If the error occurs on a device that has been installed for a long time, it may be that the batteries are too low to maintain a signal. In the following article, steps will be provided for replacing the batteries: TX-E721—Battery Replacement
