I don't know about the CS100 systems, but I solved it on my X-class. I have a self-amplified horn. If you just connect it to the paging terminals on the first port card's block, then the horn will keep amplifying the static line noise. There should be a set of dry contact terminals that go a long with the paging terminals. I used the dry contact with a relay to trigger the 24 volt power to the horn when the needed. No power, no amplified line noise.
