A thorn in my side for sure.

Any Autocall people out there?

Thanks everyone for the replies.

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.

 I was mainly soliciting anyone whom may have had experience dealing
with this particular panel.  Also, the modules tie into Autocall
TFX-400 panels and network back to the main panel..

I used to post and read in this newsgroup quite a bit; years ago.  Not
suprisingly are the helpful and numerous replies.   That's why I
thought about posting my dilemma here to begin with.

I have taken very detailed readings on all the legs of the wiring.  I
am convinced that a module(s) is the culprit.  Yes, since the system
is 15 years old it's time to upgrade (only because of this problem).
(I am not one to advise the customer to upgrade for the sake of more
bells and whistles for the technician, but this system has the Fire
Department running on troubles!)
