Скачать или смотреть Federal Signal Thunderbolt 1000T

Sep 2013 edit: Siren has been removed as the city replaces its Cold War system with 2001-130s. From what I can tell, the only sirens remaining from the old system are the 2001-DCs, which have been upgraded to radio activation, and whatever hard-to-reach skyscraper-mounted sirens they didn't feel like taking down (this last bit is speculation; there's a Model 3 mounted on a highrise building that's still in place so I'm thinking a couple of similarly-mounted Thunderbolts could also remain)

This is a re-upload of my T-Bolt video from August. I trimmed off the beginning and end of the video leaving just the test.
