What is an E22-NN trouble code and how can I resolve this?
An E22-NN trouble indicates a sensor activity failure. This trouble is caused when a zone programmed for the Sensor Watch feature fails to open within the programmed time. This feature is typically programmed for zones containing motion detectors. Verify the motion detectors are functioning properly. If this feature was inadvertently programmed, correct the program to clear the trouble. NN denotes zone number.
