Whelen WPS 4004 Siren Test Columbus, OH 8-26-15

Siren: Whelen 4004, 2.5 RPM, 560 Hz (ESC-2030) Town: Columbus, OH (Franklin County) Location: St. Francis Desales High School Test Time: Every Wednesday 12 PM Cycles: Two 23 second alerts Other notes: My first 4004. I wanted to go to a different one, but thanks to me waking up late and road construction at 23 and I-70, I had to divert to this one instead. I'm trying to look for a dual tone and 517 Hz Whelen that is in this area. I may have pinpointed the 517 Hz one, but I'm not 100% sure. I may try it next time I'm in the area. Couldn't hear the dual tone one though, so that's still a mystery. A bunch of other Whelens, including the 3016 with an 864 controller in Minerva Park can be heard. The 435 Hz one is the 4004 directly north of this one.
