he did the impossible...?

requires tone generator mod

AG1 to activate in alert
AG2 to activate in attack

no, this does NOT have a 4M blower. sounds a lot more like the early A2. also i was too lazy to make realistic blower logic.

i will never make the throaty sound of the thunderbolt with 8 bit chiptunes.

The Thunderbolt Model 1000T (Type 1000T before 1975) is a dual-tone, 2-signal supercharged electromechanical rotating siren introduced in 1954. The Model 1000T utilizes the same overall design as the 1000, with the exception of the chopper and stator. Units produced between 1954 and 1959 were exclusively 4/5-port dual tone, reusing the chopper from the Model 2T. In 1959, a new 5/6-port chopper was designed specifically for the Thunderbolt 1000T, and became the standard for all 1000T units produced afterwards. The Thunderbolt 1000T came in 1 and 3 ph variants, the Model 1000BT and Model 1000AT respectively. The Model 1000T reaches 124 dB at 100 ft according to Federal Signal; however, the decibel rating of these sirens varies depending on the blower used.
