Re: Ademco Vista-15 Install Manual

Much ado about nuthin'. The scrap of wire would have acted like a fuse and
opened. The smoke was just a bit of the battery case melting when the wire
initally tried to carry all that current. :-)

One of my installers almost burned a house down with a 12v 7amp battery
when
he was doing an install...I got there just as the smoke was exiting the
front door. He was in the back bedroom when I came in the front door.
Small
scrap of wire had shorted the battery terminals. It was just about to
flame
when I walked in. Those batteries can be dangerous. Kindling temp of paper
is 451 f...remember the novel?

| That's surprising, Crash. In the 24 years I installed for a

| battery get more than uncomfortably hot.
|
| Paper ignites at about 450º Fahrenheit (230ºC). That's hot
| enough to roast a turkey. If your control panel cabinet reaches
| that temperature, (1) something is drastically wrong; and (2)
| your control panel is no longer functioning.
|
| I don't doubt your panel got hot enough to make it seem as though
| it was ready to ignite, but reality is they just don't get that
| hot, even in Waco.
