POLL: Best-sounding mechanical fire alarm 2017

@Simplex 2903-9101

Which is the best-sounding mechanical fire alarm signal?

Due to the poll size being limited to 20 options, I decided to do two polls - one for electronic and one for mechanical. The other poll can be found here: POLL: Best-sounding electronic fire alarm 2017

Of course, I choose the 2901-9838, because its sound is, for me, the quintessential fire alarm.

Same. My school has them, so I had to choose that.
