WARNING: LOUDNESS IN PROJECT! TURN DOWN YOUR VOLUME WHEN PLAYING THIS! We've got 2 analog Whelens! One of them is a WPS-3000 (frequently called a 3016), and a WPS-4004. The 3000 went to 750 hertz frequency, and the 4004 went up to 480 hertz frequency on Alert tone. I was recording from the other side of the road at a big building just over 2000 feet away from these sirens. They are at the Countryside Hills at Stone City.
CTA, and to ME5 for the ambient sound, and DSRX100 on YouTube for the DTMF tones. And the pictures of the sirens on the thumbnail belong to their rightful owners. NEWER SIRENS: https://scratch.mit.edu/projects/874865252
