Niles has one Thunderbeam, installed after the 1985 tornado, along with several FS 2001-series sirens of varying generations and ages. Previously, Niles also had a Thunderbolt at a school which was fitted with an FC and tied in with the current system around 2004, but that school was torn down around 2007.
Federal Signal RSH-10A "Thunderbeam" - Waddell Park. This siren was installed with donation money in 1986 after the May 31, 1985 F5 tornado ripped through the city. Originally located downtown at City Hall, it was moved here to Waddell Park later on. Photos taken on 10/2/18 by firefreak57.
