Click-clack ... click-clack (the sound of relay logic) accompanied by the constant running of a motor-generator set steadily converting 60 Hz AC line to DC (in some situations).

Sure beats the hum-drum non-eventful sounds of a solid-state controller!

Is that your specialty - elevator control systems?
