Exactly. A basic electric mechanical siren just consists of a motor, a centrifugal fan called a chopper, and a stator to chop the air as the rotor spins. It can't get any simpler than that. There are tons of mechanical sirens from the 1920s and 30s that are still in service today because of how basic and easy to maintain they are!
