The one on 10th/College Rd. SWhich one?? there were two near campus.
One was over by Blankenship hall at at the building they have the excess inventory sales.
The other one was over near 10th street behind an apartment complex I think.

I have a map based on what was included in the old emergency operations plan's master list for the old siren system. Many sirens were moved around or replaced. The transition to radio activation and the Whelen system began around 1991 with the installation of WPS-4000-4's and the 3000s that had been ordered in 1989. All 110 sirens from the old system are included, types where I have been able to verify them. The following siren types were included in the old system, according to the EOP as revised in June 1990 edition. The following is quoted from the EOP (stuff in boldface are my own comments):Fletch wrote: ↑Sun Jul 11, 2021 7:20 pmThe one near campus isn't there??
If anyone knows of old T-Bolt or other siren locations I'm still interested in putting a map together of the Franklin County CD system prior to the Whelens being installed in the early '80s. I have about 25 locations mostly westside and northside.
I will make a much longer post/thread with information at some point when I have time. I am very busy and typically do not frequent the board much anymore. Hope this helps. Can't post images/screenshots of the page from the EOP as this forum I remember does not allow me to post files, so I hand typed it as it appears on the copy.3. Types:
Electromechanical
a. There are eight (8) different types of sirens within Franklin County. Those being:
Sterling Directional
Model 2
Model 5 (actually 7's)
STL-10
STH-10
Thunderbolt
Thunderbeam
ACA (one Allertor was installed outside Gahanna at a church).
b. These sirens range in horsepower from 2 HP to 10 HP. The most frequently used is a 7.5 HP.
c. Coverage area ranges from 1000 ft. to 4800 ft.
That is not one I was able to find on old aerial. If it was a 2, this would make sense as it likely is too small for me to tell what it is especially on the larger ODOT aerial tiles. It is listed on the master list, however. I cannot remember the installation date if I had a rough idea. I do have limited access to some of the Dispatch articles at least from the 80s and 90's to present (nothing before unfortunately) through my Dayton Metro Library subscription, so I saved those as PDFs off Newsbank.Tuba wrote: ↑Fri Aug 20, 2021 6:49 pmWow! Some really cool stuff coming out recently, my compliments to everyone!
Would anyone by any chance know of a fedelcode model 2 siren (or similar) on Shier Rings Rd. west of Avery road owned by Washington Township? I know Fletch that you stated you found out about it in a newspaper (do you still have that newspaper by any chance?), but it maybe had been removed with the installation of Dublin’s current system.
Once again, really cool stuff, especially that Ashbaugh Rd. Thunderbolt!
You don't happen to have any photographs of the Shawnee Hills siren, or the B&M, do you? If you did it'd be extremely helpful.Fletch wrote: ↑Fri Aug 20, 2021 4:57 am![]()
WOW-Just WOW!!!

Incredible. I was hoping something like this would turn up.
I briefly looked at your map. Some info I have:
*Siren #89: B+M horizontal siren (from old pic of Jackson Twp. fire station)
*Neil House Hotel (demolished 1981, now Huntington Center) first T-Bolt in system
*Siren #11 was originally an STL-10 and caught fire in Apr. 1974 tornado/replaced by T-Bolt IIRC
*Orel & W. Broad STL-10 according to a poster
*Binns Blvd. & Sullivant Ave. STL-10 according to a poster
*Shawnee Hills Police Dept.: XT22 (saw it in person)
*STL-10 in Plain City came from Franklin County
*Bexley Pool had a siren (possible T-Bolt) according to family
I think many of the unknowns are probably STL-10's. Many were sold off to Union and Fulton counties.
I'll study your map a bit more. But you've got a way more comprehensive map than I have.

Sure! These images were taken from the Ohio Department of Transportation's aerial imagery archive. You will need to download the KML and open it in Google Earth Pro. Smaller image tiles show more detail, whereas larger tiles are more zoomed out and do not.Sifed1 wrote: ↑Sat Aug 21, 2021 3:14 amWow!fire_freak_57 wrote: ↑Fri Aug 20, 2021 1:44 amI have a map based on what was included in the old emergency operations plan's master list for the old siren system.

Great work! Just one question though... where are those black and white, vintage aerial photos from the map from? I've looked on Historic Aerials and Google Earth and neither of them have imagery that's that clear. Could you tell me where those images are from?
