560 Hz Whelen 4004 Siren Test Columbus, OH 8-26-15

[TommyBNSF]

I would've went to a different siren, but I was running late so I diverted to this one. I'm trying to locate a dual tone and 517 Hz Whelen in the area, and I may have pinpointed the 517 Hz one, so I might go for that next time I come down here. Anyways, this 4004 sounded pretty good and had some nice echoes for the second activation.
