From what I've gathered through Google Earth, streetview, and actual field visits from people, there is only one Alertronic AL-7200 left standing; that being the one on Scarboro Road. The one on Blair Road and Perimeter Road, at the K-25 plant, were removed around 2020-2021. The two located within the K-25 plant were removed a number of years ago.

Locations in and around Oak Ridge were removed or replaced sometime in 2012, most of them being replaced with T-121s or the occasional T-135 AC/DC. The earliest known replacement of one of these sirens was around late 2004, this unit being located just northwest of the disc golf course. On Google Earth, it can be seen still standing, but there is a T-121 just on the other side of the road.

So far, Oak Ridge is the only known buyer of AL-7200s, however, there are some speculations that there were four located at the Blue Grass Army Depot in Kentucky. Satellite view really makes it look convincing that there are 7200s at BGAD, although I'm a bit skeptical of this as there is one particular unit that looks to be outright missing a horn, and I would be quite surprised if something was able to completely remove three horns in one vertical row. Makes me wonder if A.C.A. made different configurations of this series, and this particular unit is a single-row model. Unfortunately, there's really only one way to find out; that being to go and get pictures.
Could we see the satellite images?
Here's the supposed BGAD AL-7200s.

Siren #1. This is the one that makes me question if they're really 7200s or not. It's clearly missing a horn by the looks of it.

This is somewhat unrelated but as long as there is a thread about Oak Ridge I may as well ask. Apparently, according to a map, there are two Whelen 3000s suspended from a water tower? Where is the proof of this?
i have photos of them form a few months ago on my trip over there

STH-10s would have twelve horns, these clearly have eight. I thought about them being T-121s, but they've been up before T-121s were even a thing, by the looks of Google Earth satellite.

Would you send them by any chance? Also, those sirens in the satellite photos look undoubtedly like T-121s. There doesn't appear to be more than one layer to them, and a T-121 missing a horn is not implausible.
Sirens may not be sexy, but they sure work.

The core the horns attach to is larger than that of a T-121, and in some pictures you can make out a core in the shape of an octagon, just like the Alertronic 7200. Definitely look too old to be T-121s at least, even the oldest ones don't look that bad yet. Fiberglass holds color pretty well over time

They certainly look like the Alertronics. Has anyone been over there to take pictures?

Not really something that anyone can do. It's government/army-owned property; you can't really just walk on in to the facility and go get pictures. If you did pull something like that off, then congrats on being sent to federal prison :lol:

Only idea I got is if someone can contacts somebody there about the sirens and see if they'd be nice enough to get pictures. I'd be very surprised if there'd be somebody willing to do that.
