Thanks for the tips. This problem started about 4 weeks ago, the system has been in place about three years with no problems. The customer said nothing obvious had changed in the office (no construction, new equipment, etc) that could have started this problem, but since the problem source could be so many things who knows. The noise is not consistent, it can happen once in two hours, three times in ten minutes or not for days. When the noise occurs it pretty consistently last 5 to 10 seconds. A buzzing/staticy noise that typically increases in volume before just stopping altogether. This one is going to be a pain in the --- to figure out!

Are there any water leaks in the roof or tenant

above ?

Also Valcom has tech support in the factory.

How many speakers and do they all make the noise sounds like it may be a bad amp on one speaker if you can short the tip/ring then it should silent all outside interference then if one speaker is nosiey replace it or if a group of speakers is noisey you have wire problems

can it be cell phone interference? I have my cell phone next to my desktop speakers and the sound often goes BONKERS!

This could be powered from 24 volts DC or a Valcom AD to 24 volt adapter. That would eliminate the AC power supply. Two cheap car batteries or whatever and they recharge them at night.

You could use an isolation transformer on both the 2002 and the music source, that would eliminate AC power hum.

The power source puts out 12 "UNITS" of power, could you be exceeding this with the number of horns?

Are all of these speakers home runs?

I don't know how much experience you do or don't have, but with any of these posts, the more research you do, the more info you give us, the more situations get resolved.

A little more information might be good to point the way.

You do know that the last post was almost a month ago?
I assume that this issue was long since resolved.

Well the post before mine was a day earlier than mine. OPPS I got caught trying to help and didn't notice the post before the post before mine.

Now if there were some moderator around who would diligently determine the thread was finished, then said moderator would make a last post: This thread is closed, and lock its little keyboard input out.

I nominate Paul to be responsible for determining a thread to be closed and make it impossible for future comments. Its your job now, I just voted and no one else gets a vote, that is just the way it is.

Shut it down Paul, you are in charge and you have determined this thread is finished because I said so.

Thanks, and Happy New Year, L'Shanna Tova 5767
