RPM 2 Audio Alarm

Has anyone found a way to attach an audio alarm to the RPM 2? I have successfully attached a blinking warning light, but I would also like to attach a warning horn or buzzer. With only one wire coming from the RPM 2, I am having trouble finding a audio alarm that will work.

Any suggestions or part numbers are appreciated!
