Ladder truck warning buzzer specs

Question asked by james1wolf on May 31, 2017

Is there a requirement in upcoming codes for fire apparatus to make the human generated warning buzzer a different tone than the system warning tones in the driver's instrument panel?  In some tractor drawn aerials the tillerman stepping on the stop button sounds the same as the check engine warning alarm.  The back up button on a cable mounted on the rear of some apparatus might have the same issue.  Thank you.
