The SD-10 was an outdoor warning siren produced by the Federal Signal Corporation. The model number stood for Special Dual Tone, 10 Horsepower.[citation needed] The siren itself is essentially identical to a Model 5T except for the housing. The SD-10 came out in approximately 1954 after the Office of Civil Defense issued a requirement that all sirens be dual tone to distinguish them from vehicular sirens. However, by the mid to late 1960s this requirement was ultimately forgotten about. The SD-10 stayed in production until at least 1987-1988. The siren was quite a popular civil defense siren as a lot of towns and cities bought them, with a notable example being Los Angeles, CA incorporating approximately 80 SD-10s into its system. Many SD-10s are still in service to this day, but some also remain silent, as a testament to the times where the people of the US lived in fear of a Soviet attack. The siren has appropriately gained the nickname the wire spool due to its shape. The SD-10 could, like pretty much any siren, be mounted on a roof or pole with the appropriate mount. The SD-10 was offered in both three and single phase (A and B respectively). As mentioned earlier, the siren was powered by a 10 HP motor. The controls used on the SD-10 typically were RC-5 cabinets, but in some cases, example being Atlanta, GA, they could be run off whatever the city had on hand. In Atlanta's case, the controls were nothing more than a General Electric traffic controller, and a Bell System phone relay.
