Whelen WPS 4004 Siren Audio Columbus, OH 10/3/18

Siren: Whelen WPS 4004, 2.5 RPM, 465 Hz Town: Columbus, OH (Franklin County) Location: Faith Community Wesleyan Church Test Time: Every Wednesday 12 PM (Voice 1st Wednesdays) Cycle: Two 23 second alerts, plus 4 voice tests Other notes: I made another return trip to Franklin County for sirens, although this time I used a couple of my recorders, and I came on a 1st Wednesday so I also got the monthly voice test for the county. This is a digital ESC 864 4004, and has a pretty sweet reverb on both wind ups and wind downs. You can hear several other sirens after both wind downs including a couple of 435 Hz 4004s, which surprisingly are not too common in the county. Support me on Patreon:   / tommybnsf
