Abstract
An emergency vehicle multiple sound siren disabling circuit is disclosed having a multiple sound siren circuit for emanating signals equivalent to a particular type of sound with an amplifier adapted for connection to a speaker. The siren circuit has a switch for selecting respective siren sounds and a circuit for disabling the multiple sound siren when the emergency vehicle transmission is placed in a park or neutral position. The circuit further disables the multiple sound siren after the emergency vehicle transmission is removed from the park or neutral mode, and enables it again after selective inputs thereto.
