The Model 5/7 was a siren produced by Federal Signal Corporation. The siren came in the three different port ratio's. 12, which is the most common. 8, which isn't found on many models, and 9/12, only found on Model 5T's. A Model 5A is a three phase siren, and a Model 5B is single phase. Model 7's are three phase sirens like the Model 5A, but seem to have a faster windup. However, Model 5T's are dual tone only.
