My alarms periodically just don't go off (not even the chime backup). I have two alarms in two different rooms set one minute apart. When this problem happens, BOTH alarms fail to go off. It's happened three or four times over the past few years. I used to be on the s1 controller and thought that may be the problem, but recently moved to s2 a few days ago, and it just happened again. Here is my diagnosis number: 1260039986
