Whelen WPS 2910 Siren Test @ Westin Hotel, Rosemont, IL – 6/25/18 (w/Activation Tones)

This is the other Whelen WPS 2910 by the Westin Hotel that Rosemont has. Compared to the siren at Margaret J. Lange Park, this one was didn't have a bent bracket and was less loud up close. This is also my very first time using a radio scanner, which my friend recently got to hear the activation tones used to test and shut off the sirens. I apologize if you didn't hear the tones right away as we were flipping through frequencies to find the right one. Rosemont tests their sirens every Monday at 6:00 PM.
