This is my map, which is intended to document every known location of Sterling Sirens and related products, including both past and present. I will mark anything that is a Sterling Siren, including removed sirens, as long as there is an exact location available.
Please let me know if there is a location I'm missing and send direct coordinates, and I will have it added.
