what is a tone generator? what does it look like? Is there picture of one?

Doomsday Sound 500LT.

I've been meaning to ask a question about these sirens. My understanding is that many electronic sirens use a recording of a mechanical siren when sounding off tornado or air raid alerts. My question is when they are winding up and winding down, is it the recording that is starting and finishing, or...
