Normally, I\'ve found that the addressable fire systems will give me a
trouble when a module is begining to go haywire as it misses it
polling sequence. With this panel and modules, as a module starts to
become defective, either every module on the loop goes into trouble
for an instant, or an alarm happens on an unrelated module. This is
very disheartening. I find it very hard to believe that the Thorn
Autocall passed any UL inspection with this monkey-business. Maybe
that\'s why they are not in the US anymore.
