Here is my map of the sirens in Shelby County, AL's sirens. It's not a uniformed county owned system; the various towns and FDs own the sirens independently from the county. Read the description. This map was based on a list of sirens from the 911 website and was last updated in 2010. There are a few approximate locations in the map and some that I just can't find for the life of me. The are also a few extra ones I found that I added to the whole lot. This is also the largest map I've made with over 100 sirens. If you have some I could add leave a comment with the location. Also check out Columbiana's system. Yes that is a system of T-128s... that makes about 11 in the state if I could find the two missing ones in their system.
