Kosin store outdoor sound systems

This is a Whelen warning siren seated atop the Ashland, MA fire station. It plays the Westminster Chimes at noon, and sounds the "air horn" alert repetedly during a fire call. I've never seen a video of this model of siren playing Westminster Chimes, so I thought it was pretty neat. Note you can hear a clicking noise a couple seconds before the chimes start. This is the sound driver turning on. Any info on the exact model (and correction if it's not Whelen) would be greatly appreciated! © Katsuki Lennox
