Green button to activate. Honestly this could be better but being done in a hour, this is pretty good. Does this count as speed art? Listen to the sound...
The Federal Signal Xt22 Series is a series of sirens built from 1952 to the early-1990's. The sirens consist of 22 horns; 10 on the bottom, and 12 on the top; and produce 113 db.There are two main sirens, which also have different versions. The 2t22 is the original, which is capable of producing Attack and Alert signal tones; while the 3t22 is capable of producing a special "fire signal" tone known as "high-low". ~Trivia~ There are two versions of the 2t22 and 3t22; 2t22A, which is a 3-phase version of the 2t22. 2t22B, which is a single-phase version of the 2t22. The same A/B modeling applies to the 3t22. The 3t22 has added "solenoid" boxes or panels on the sides of the siren to control the "damper" or "plug" to generate a high-low tone. The Xt22 series of sirens has proved to be very popular and very reliable. The 3t22 is merely a higher upgraded version of the 2t22, only with additional features. (Aside from having higher or lower horsepower or energy.)
