The Siren Board

I meant to post this a long time ago. I updated my Columbus map and made a fairly accurate map based on the 1981 study for more sirens. I included radii of each siren as indicated by Federal Sign and Signal and Whelen. The 560 Hz 2810s have been adjusted to fit the radii of the 2910 as they get the same ratings per pitch.
