That right folks. It’s the one... the only... the mighty Thunderbolt 1000T Air Raid/ Tornado Siren. This siren was manufactured by Federal Signal from 1952-1990 in three Variants. The 1000, a single toned version, the 1000T, a dual toned version, and the 1003, a version with solenoids which allows it to do a firecall signal. Many of these sirens have been replaced by newer sirens as of today, but some still serve with Volunteer Fire department’s and towns around the USA. Some are even restored and used by enthusiasts. As for the siren it’s self, 1 is to open control panel, and 2 is to activate the rotator, but don’t forget to push VTOL all the way up. Credit to the fully rotating rotators goes to bjac0. For comparision on internet look up “Thunderbolt siren”. Before you ask also, I’ve been interested in Tornado sirens for a long time. It’s just one of my hobbies to record them. So far, I’ve recorded two. A 2001-130, and an STH-10.ENJOY, LIKE, AND SHARE WITH YOUR FRIENDS.
