I live in the St. Louis metro area and just saw your post and familiar with Columbia's old sirens. So I went online and found out that the City of Columbia purchased 5 new sirens, strategically placed so that 100% of the city has siren coverage, whereas the old system, installed in the 1960's, consisted of 3 sirens with 9% coverage. They activate the new sirens at noon and 6 PM every day, using the Westminster Chimes tone.
