The high pitched sound is a combination of a high chopper speed level (most likely level 7) and a reverse wired blower.

I thought ATI's were 500hz. Are you talking about the ones with the wind-up?

Early ATIs made in the very early 2000s used a 1000hz tone. There aren't very many left, since most ATIs from that era have long since died or had the controllers replaced.

Some guy who is interested in Taiwan's siren system as well as a few others,
Have I heard a siren? Yes, The Darley 3V8 in Columbia, California doing a noon blast.
