The Siren Board

So I'm trying to figure out where it is but I was told that Green Bay has a DSA somewhere. Not sure if it's at Northeast Wisconsin Tech as there is a mystery siren over there. But there was another mystery siren at Tower Park over on Ridge Road and looking at the correct angle, you can see these speaker arrays that point downwards from the side of the water tower, but there's only one each which Federal Signal doesn't even sell a DSA1 on the market. So what is this siren at Tower Park and does anybody know about any DSA in Green Bay?

Hmm...They might be either PA speakers, or just security cameras. It's hard to tell from this angle.

Yeah those don't look like sirens.

They could be lights to deter vandals from messing with the tower.

Those are not sirens, they look like light posts. I don't think the siren near Tower Park can be seen in the street view. Anything relocated or installed after the map's viewing date won't be visible unless they update the street view photos.

Most of the sirens around Green Bay are primarily composed of Thunderbeams, STL-10s, Model 5s, 2001s, and Tempests (121, 128, and 135).
In ages past there were 500s all across north central and north east central Wisconsin. I don't think any of these are left aside from Marshfield's.

The DSA was reportedly located near a rail yard in Ashwaubenon. I don't have photos of it but apparently it has two sets of speakers going both directions.

Okay thanks. And from what I know there is also a 508 on Main & Commodity. Also do you know what's at Northeast Wisconsin Tech?

Several years ago I saw a dsa somewhere outside of greenbay, and I could see it clearly from the highway. I don't know if I have picture somewhere but I can picture it in my head.

I think I may have had the photo at one point and I think k I had posted it on the forum Charlie made when we thought this one was dead. Are there archives on way back machine or something? I don't remember the url for Charlies forum.

Northeast Wisconsin Tech's siren can't be seen from the maps - they haven't updated that route's street view in years.
The official county map gives it a range of 1 mile which implies it is a Model 5, STL-10, or Thunderbeam. The newer sirens are given larger ranges.

Charlie's old forum appears to have been abandoned. If memory serves, it was also called "The Siren Board".

Major but worthy bump. I found the picture of the rumored DSA near Green bay while going through pictures on my old desktop. This was taken looking out the left side of the car as we drove west down WI29 when this was taken. It was just outside of green bay. https://flic.kr/p/ScPGgm
I've been looking for the high voltage power lines seen here for 10 minutes now and can't find anything.
