Re: About Atlanta's old system...

Is that the original engine still connected to the chopper/stator? Regardless, that Mobil Directo's an awesome find! Shame the horn's gone but at least the rest of it's still there. It appears to be, this siren was gas powered throughout its entire use period and as far as I know, the engine was ne...

Re: About Atlanta's old system...

Well this has been a pretty long time in the making, I had hoped to get to this last year but between life and the pandemic, things just got too crazy. Today though, I met up with Brendan W and Will (TNT1001) and we are pleased to announce that as of Saturday, April 3rd 2021 the Atlanta Stockade Mob...

Federal Signal 2001 and DSA-4 Sandy Springs, GA

With clouds looming, I wasn't sure if Sandy Springs would test today, but thankfully they did. This is one of the two setups that the city has at their parks, which consist of a 2001-130 and a DSA-4 both on the same pole. Typically, these sirens are tested in 3 minutes of wail/attack on the first We...

ASC T-121 test Oak Ridge, TN 6/5/19

After getting a semi-successful test at the ETTP Alertronics, I went with Peachtreesirens, 4j25, and Sirens of Cincinati to record the Oak Ridge, TN system of Tempests. The coverage is great on this system and it makes for a cool sound on test day, especially with the rain like the past two times we...

ACA Alertronic 6000R + Ambiance Oak Ridge, TN

I ventured up to Oak Ridge, TN once again with Peachtreesirens, 4j25, and Sirens of Cincinnati to catch a video of the Alertronic system that is used at the East Tennessee Technology Park. This was formerly part of the K-25 gaseous diffusion plant, but is being re mediated now, so sirens are still n...

Whelen Vortex Install Ganesville, GA

Over winter break, I got to visit Gainesville, GA for the replacement of a Federal Signal Modulator 6048 with a Whelen Vortex R4. The install was done by McCranie Warning Systems and Table Rock Alerting Systems (Stormsetter4). Seeing the whole process really puts into perspective how much effort goe...

Re: Clayton Whirlwind

Here is a Clayton Whirlwind in Cadwell GA, these sirens are pretty rare and this one happens to still be up. They were cast in Deland, FL and to my understanding it was after a member of the fire department became interested in casting. He then set up a small foundry with a few men on the edge of to...

Re: ACA Alertronic 6000R Oak Ridge, TN

The wind down is rather eerie! It surprised me how long it took to wind down, it was really cool to hear in person with all the echoes. The whole setting was rather eerie in the rain and to know that if these ever went off for real it wouldn't be for a tornado, but for a nuclear disaster.
