WARNING: LOUDNESS IN PROJECT! TURN DOWN YOUR VOLUME WHEN PLAYING THIS! Never thought I would find this. I thought the analogs were both replaced by just the 2001-130, but that 2001 replaced the WPS-3000 while the replaced WPS-4004 was by an ASC T-128. They're louder than the old ones! Same spot recorded which is over 2000 feet away from these sirens. Located at Countryside Hills at Stone City.
Louder means they have choppers and stator units instead of speakers, because they are both electromechanical sirens. CTA. And the pictures of the sirens on the thumbnail belong to their rightful owners. OLDER SIRENS: https://scratch.mit.edu/projects/859687530
