[Hai-users] Voice Board

[Andrew Comstock]

Wow, this group has been so quiet lately.  I hope all is well at HAI and
Aegis...

I have one of those frustrating intermittent problems.  We have a customer
who's voice board periodically stops working.  I don't think it's the board
(I changed it once).  Last week, I went out - pulled out the flush mount
consoles to examine the speaker wiring.  Everything apeared okay; no wire
nicks.  When I put the two consoles back, the voice worked again.  It worked
for a week.

The problem effects both consoles, that's why I originally repalced the
board.  I'm leaning towards a wiring short on one of the speaker leads, but
I can't find any evidence.  Any suggestions?

And (different location), I have another outdoor temperature sensor failure.
Has anyone come up with an aftermarket solution?  Has there ever been an
analysis to find out what fails?  I know this group has had previous
discussions.  Essential Home Systems sold about 30, and we've replaced a
very high percentage.  Strangely enough, I've never replaced the one at my
house (almost 5 years).
