The siren is based around a motor-driven concept, while the dampers are pneumatically operated and controlled by a computer system. I think the earlier first generation units used a code wheel (like a music box) that controlled the dampers using electromagnets, though please correct me if I’m wrong.

You are correct that the first generation used electromagnetic SOLENOID SHUTTER MECHANICISM basically the electromagnets are called solenoids allot of federal signal 3T22 And the THUNDERBOLT 1003 Had solenoids to do a fire signal called HIGH LOW for fire calls when we say fire it's actually two silbables one high one low.
