[Hai-users] Strange Behavior of OmniProII

[Bruce Schroeder]

I wrote a few weeks back about the beginning of this problem with my 
OPII (actually HMS 1100) but got no response.
I was hoping someone has seen some of this before and may have an idea 
where to start troubleshooting.

Recently have seen increasingly frequent "Fuse Trouble Now" events. This 
is the solid state fuse (not the glass fuse). Sometimes lately when it 
happens it also does a system reset, may or may not lose the time and 
may or may not lose the voices (eg. says "message 67" instead of 
"Driveway Alert").  It is happening several times a day now, and not 
always a fuse trouble event but one of the others I listed. I have reset 
RAM and reuploaded a few times. Have not yet reset EPROM.
During one of the failures an event is logged that says "System Reset" 
then "Zone 215 trouble"  and then "Zone 215 Trouble Cleared"---this is 
interesting since there is no zone 215.
Had an event last week where we set off a smoke alarm and when the horn 
sounded, it immediately set tripped the fuse. I believe the sounder is 
connected to an output but that should be the only power draw on the system.



The recent changes to the system, some of which may have been done after 
the problem started:
Replaced a few defective motion sensors
Added a contact closure to an open zone on an expansion panel
Made some changes to software in Crestron that communicates by Omnilink
Moved a driveway sensor.


I guess we can remove/test the sounder but could it cause these problems 
when not active?
Any other ideas? Does this sound familiar to anyone?

thanks!!!
