CT 475 - Short blip/static sound every 5 minutes.

28 July 2013 - 04:54 PM

I have an intercom system that is running on 3 CT 475 amplifiers.  I have recently notice a short blip/static sound coming through the speakers every five minutes.  Not sure what is causing it.  I hear it in all parts of the building and I have tried to narrow it down to a specific area by shutting down one amplifier at a time.  No matter what the static blip is still there, unless they are all powered down of course. Not sure what else to look for?  Any ideas?
