Question about old Austin FD Tones

[FireRescueCapt]

Does anyone know what the format used for the old tone alerting system used by Austin FD before they switched to Locution? I know it was activated by a Zetron console, and it sounded like two short "blips", repeated for each station, with a long alert tone at the end. Then, after the dispatcher announced the call, a "reset" tone was given.

Thanks,
Craig
