I'm not to smart about this kind of siren but what I figured is that if you were to look over on the bottom left corner there is a little air compressor nut, so essentially it ran from a tube probably connected to a timer or manual button and to a air compressor. The air then rotates the chopper the...

Here's where the M-3 nomenclature comes from. The single-head models were 3 HP, while the dual heads were 5HP.

Wait, wait, wait, hold up. Sterling made coded sirens?

Yes they did! though instead of dampers/solenoids they used motor brakes

Hmm thats odd.
