Here is my submission:
Miami-Dade County FSMC
Map Information:
In 1955, Miami-Dade County purchased 7 Chrysler Warning Sirens, along with 64 Thunderbolts, 2T22's, and 2T's. In the mid 1970's, the county had grown quite a bit, therefore the county purchased another 121 Thunderbolt Sirens to cover the area and also retrofitted the existing sirens with Federal Signal Siratrol Radios. In the mid 1980's, Dade county had grown considerably once again, as a result the county purchased 26 ACA P-50's & Allertor 125's, covering the area that had grown. The 7 Chrysler Sirens were also converted to electric, 7 140hp electric motors were purchased and installed in place of the old Chrysler Engines into the old Chrysler Sirens to make them less maintenance intensive and more reliable. At the same time, the entire system was upgraded from Federal Siratrol Radio Controls to ACA CompuLert 800 radio controls. In 1999-2002, all of the Old Federal Signal sirens and the 7 Chrysler sirens were completely Refurbished. The sirens were powder-coated yellow to help withstand the salt air conditions. In 2014, the old Federal 2T Sirens on the Florida International University Campus were replaced with 5 Modulator 3012B Sirens for voice capability. 5 Modulator 8032B's were also added in the Virginia Key area. At the same time, the entire siren system was upgraded once again, and all of the existing sirens were retrofitted with Federal Signal FCTB Radio controllers for 2 way activation and monitoring.
