Скачать или смотреть Whelen WPS 4004 Siren Test & Ambience, Mount Prospect, IL - 12/3/19

*This siren has since been replaced with an ASC T-128
*Siren starts at 0:48

Monthly test of the tornado sirens in Illinois. This 4004 is located on Algonquin Road and Linneman Road in Mount Prospect. Unfortunately, it wasn't very loud at all, and it only did a 30 second alert, but I guess the ambience makes up for it. At first you'll hear the Whelen's in Arlington Heights along with Bensenville's Cyclones four miles away. At first I thought it was the Elk Grove Village P-50, but you'll hear that in the distance more clearly after this 4004 shuts off. Also there's an RM-130 that was stuck on west of here going for 5 minutes, idk which one. Same goes with that mysterious Whelen that does 435 hz. Anyhow sirens in Illinois are tested on the 1st Tuesday of every month at 10:00 AM.
