It's at the Federal Signal Plant in University Park, IL. They have all the sirens up that they currently manufacture so they can demo them for customers.
My father used to work at a small steel firm literally right across the street from Federal, and claimed that every once in a while, he would hear the Modulator play music! I asked him when they test the siren, but they do not do it on a scheduled basis.
