The Siren Board

Your GDC could be from the 1940's, if that helps. Newer models had the "GCS" tag, according to Vintage Collections.

So, I was scrolling on the ARS Reddit page, when I saw this photo.

Does anyone know where this is located?

Maybe you should make a Michigan Supermap! I know alot of locations in Michigan, so maybe I could help out!

The Sparton in Hanover Township, Michigan is removed. Was replaced by a Sentry.

Belleville also has a GDC Type 341 on their police department. It is an 8 port model, and goes off every Friday at noon.

Maybe you should take a picture of the tag on the rotator box so we can see when it was manufactured!

1. Federal Signal Model 5/7

2. Sterling M Series

3. ACA Allertor

4. Sentry 10V2T

5. Whelen WS-2016

6. ASC T-121

I believe that the Model 7 siren in Clayton, MI at their fire department does noon blasts. I think it's every saturday.

Ok, thanks for the advice! I will export the map and change the icons to the colored pins.
