Re: Ademco Vista-15 Install Manual

Exactly. So, you don't think a short can happen in an alarm panel? Man I
wish I had saved the last semi-exploded battery I removed from an old
neglected system a few months ago.

| Yes, I do remember.  It's science fiction.  Your tech almost

| presence of paper in the cabinet.  In fact, such an event causes
| an almost instantaneous burn as the wire heats up in a split

| inadvertently miswired a second battery to a Napco battery
| harness (the same device about which I posted a really dumb
| mistake a year or so ago:)).  Fortunately, that happened on the
| bench in my office.  The copper wire turned white hot, burned off
| the insulation and incinerated itself.  Inside the panel this

| During the normal course of use the panel will not heat up and
