Piezo 4-Tone Siren 120dB – Police, Ambulance, Fire & Air Horn | Jaycar

One siren, four voices. Police wail, ambulance tone, fire engine, or a proper truck air horn — you pick with the included controller. Hits 120dB from a standard 12V DC source. The body is sturdy moulded plastic with a metal mounting bracket, so it stays bolted down when it's screaming across the yard. No guessing which tone to wire in; just flip the switch
