How to deal with Tampered Sensor

One of my 6 contact sensors shows Tampered. The other 5 are Closed. All 6 show a History of opens and closes. All were installed with 3/4 inch separation between the two parts. What is wrong with the Tampered sensor?

Hi @BobNichols. A Tampered message means that the cover is not properly seated on the Contact Sensor. Try taking the cover off and putting in back on, being sure that it “clicks” into place.
