We recently had a new Nortel phone system installed at work.( I think its called a BSM200)
We have overhead paging, the phone system is connected to an old stereo ( amplifier, tuner and tape deck).
Once the phone system was installed the paging worked fine, but there was a terrible hum coming from the speakers ( except when someone was paging, then it would go away for the duration of the page)
The phone installers said we need a grounded loop to correct this.
I had an electrician install the grounded loop.
The hum went away.
But now we have problems with the paging system working intermittantly.
I have checked all the volumn controls etc.
Yesterday the paging system stopped entirely. I went to our stereo, and, just playing around, turned on the tuner, tested the paging system and it worked, so I assumed the tuner had to be on for it to work and someone had turned it off. Hours later I get a call that the system is not working again, and the tuner was still on.
Obviously I'm no tech wiz. I have no idea what the problem might be.
Any advise?
I know I am about to begin the " it's the other guy's fault" game between the installer and the electrician.
