  1. I don’t see any steam coming out so they must be using compressed air. It won’t sound the same.
    My Friday afternoon English class was on the 4th floor directly across the parking lot from the Huntington Ave firehouse in Boston. Every Friday at 3PM they tested air raid siren on the roof of the 3 story firehouse with 150 psi air but it was designed and built for 400 psi steam. Not the same.
