Before I go into the description I'll mention that the SD-10B is NOT active.
Saturday I was at Columbus State University to usher students, staff, and families for graduation. While I was on campus and had a break I figured I'd swing by this SD-10B to record ambiance from a system test. I've actually heard the system from the campus a few times during tornado warnings, but due to the fact that the campus is situated on the edge of the coverage radii from the nearby sirens, two 2810's just under a mile away to the northeast and west-of-south, it would always be somewhat faint. It's a bit of an awkward situation. By not directly replacing this siren a coverage gap actually opened up in the area. It seems that the planning of the current system relied on the surrounding sirens to cover the area. Looking at a map of the system coverage there is a small gap that contains a sliver of the campus that encompasses the area around the Cunningham Center and the area to the north stretching from the nearby Super 8 to about a fourth of the Peachtree mall premises. Had the SD-10 still been active it would have at least covered the part of the campus in the gap and some of the area to the north.
This is the last of the old sirens left in tact in the city of Columbus. There are some remnants of the old system left in the city mainly in the form of old poles from former sirens, notably the two 2810's downtown mounted on the poles of the Thunderbolts they replaced.
