Decatur, GA Whelen Vortex R4 test 10/4/17

Fri Oct 06, 2017 3:36 pm

This was the last recording of October 4th that I took after racing down to Decatur from Oak Ridge, TN. This siren is located at Glenwood Elementary School and tests on the first Wednesday at 5:00. The system in Decatur is comprised of 4 Whelen Vortex R4s and was installed in 2009. In addition to this, there is a Whelen WPS-2902 at Agnes Scott which can be activated by the city of Decatur, however I am unsure of when it tests. This siren actually surprised me because it was quite loud, I could actually feel it in my chest. If you are ever in the area on test day, I highly suggest that you record one of these sirens. Here is the video:

Agnes Scott tests with the rest of Decatur. You can hear it loud and clear in my video of the failure at Oakhurst School.

The 435 Hz siren heard in that system is the 2902 at Agnes Scott. It's got an older ESC-2020 driving it, and you could tell it wasn't rotating. I heard it in the background up there when I recorded that other Vortex. It appears that they have it set up as part of the city's system, since it activates and shuts down at the same time as the Vortexes.
