Well, I have some bad news. The supposed active Sterling N5 in Algood TN is inactive. I was given false information about this siren being active. I was told there were 3 sirens in Algood, TN (assuming their 130, SRNB, and this Sterling.) Well, turns out this siren is not one of their three. I found another 2001-130 on the outskirts of town. This 2001 was most likely installed around the same time the 2001-130 off of highway 111 was installed.
Location of the 2001: 36.213048,-85.443340
