Hmmmmm,  Bob, That doesn't even sound vaguely familiar.  But hell, it's get=
ting so I can't even remember how to spell memnorie.
.
Les, I don't know anything about Vistas but I'd go with the capacitor probl=
em. I've got some reeeeeely old Napco panels out there. A few, maybe 50 yea=
rs, and they've been failing one by one through the years. I'm pretty sure =
it's due to leaky electrolytic capacitors. you can see some of them leaking=
 on the PCB. These were manufactured long before the China capacitors were =
around so I think that's why they've lasted so long.=20
.
11 years sounds about right for when the China caps came out.
I've still got some Napco 800's, 850's and 854's out there and one Ademco 5=
600 wireless system I'm waiting for to fail. I suspect they'll all fail bec=
ause of capacitors.=20
.
Other than that, I went on a weeks vacation and when I got back I had 15 ei=
ther panel upgrades for remote access with Napco Starlink Connects cell rad=
ios or installations to do. Seems people are willing to pay the extra bucks=
 per month just to be able to do something new on their cell phones.
I therefore highly recommend vacations.
