HOR Super Sirex (Decapitated) - West Marble Place & South Clark Street on the Field Building. Photos submitted by Joseph S.

HISTORY - The City of Chicago had a system of lots of Federal Enterprises Thunderbolt 1000s, STL-10s, and Model 7s and a Model 5, 5 HOR Super Sirexes, and as low as 8 Chryslers, and as high as possibly up to the 20s. These sirens were all replaced with various series of 2001s which do attack for tornado warnings, and in downtown there are a few Modulators and DSAs scattered about, which do wail for tornado warnings. 2001s and MODs formerly did fast wail and alternate wail (respectively) for tornado warnings.

HOR Super Sirex - This photo was found on illinoisfiretrucks.com. The photo was taken at N Dearborn Street & W Illinois Street, viewing the Super Sirex located on a building near N Michigan Ave & E Grand Ave.
