Fred has a good point and I would point out that the reason for diode isolators is so that the warning lights remain independent. This can be easily accomplished with inline diodes soldered in series with each wire to the buzzer. I purchased a very loud alarm/siren from Radio Shack and wired it to the back of the panel. It was so light that I left it supported by the wiring. There was no need for any new holes, it is plenty loud enough to be heard from where it is. I wired my inputs from the idiot lights. Has worked fine for many years now.
