System worked perfectly, parmedics took me to emergency where they diagnosed dehydration and an infection that I did not know about. I returned home Friday afternoon and am feeling "normal" again. One thing, the paramedics banged on the door and I had to direct them to the lock box and tell them the code to unlock it and get my key. I asked them about this on our way to the hops. They said that the info and code was "in the records" and they would have found it if I hadn't been able to answer. If I hadn't been able to answer, I wonder if they would have referred to "the records" or would the fire dept. have removed a door or window. I should have asked but didn't think about it.
