Thanks for your advice. Your knowledge is much more advanced than mine as I have not kept up with the technology. Based on what I see as my needs at present, however, the simplest possible technology will suffice. I'm sure you will be critical of my complacence but for now all I want is something to monitor a single disguised Dual Tec (or other similar unit) which is located in the kitchen of my summer home, to offer some rudimentary protection when I am away for extended periods, including winter. This will probably work only for a certain type of amateur intruder who will not know "all the tricks" and exit when they are surprised by an alarm. At present, I have no perimeter protection installed, though of course I should. Nor am I connected to a monitoring service or dialer. The old Ademco did just fine for many years. All it has to do is reliably turn on the alarm in response to an open loop, and terminate it after a preset time. If I find the panel is at fault here I will consider the Vista. The 1032 has no keypad, only an entry-exit delay capability which is really all I have ever felt I needed. Today I examined the opening and closure of the relay on the Dual Tec. When closed, the panel sees about 1976 ohms in the loop, which is identical to what it sees with the DT out of the loop. This second DT has been properly wired and double checked, as was the first one. In limited observation, I know of two instances in which the alarm did not shut off when the loop was opened by the DT and two in which the alarm did shut off when the loop was momentarily opened manually. Of course I do not regard that as an adequate sample. I need to get away from this project for awhile but will report back when I have examined many more instances of each condition. At present my gut tells me that the DT is not being activated over and over during the alarm period, though I will look for that too. With that ruled out, I will then try to rule out the panel, though all signs would then point to that as the culprit. Thanks to you and the many others who have commented. Over time I will look to set up a better system, but my curiosity is now really focused on determining whether the 1032 is truly defective. I have downloaded and am studying the Vista manual. Frank
