The Modulators in Little Silver, New Jersey are used to call volunteer fire fighters. But, they do not sound wail or westminster chime. They sound what I'd call "Code-3." It sounds like this:
BLEEP-BLEEP-BLEEP----------------BLEEP-BLEEP-BLEEP------------------BLEEP-BLEEP-BLEEP (repeated many times).
Does that sound come with Modulators or did they set it up that way? I'll give you the Modulator locations in Little Silver that I know of. The first one is at the Little Silver Volunteer Fire Co, 543 Prospect Avenue. The second is on White Rd near the Shrewsbury town line, a little over 100 feet east of the railroad tracks. How do they do Code-3?
