I'm not sure if there is a specific rule on this matter. I search around and really couldn't find anything. I do remember the past couple years people have complained about teams that have had sound systems and sirens on their robot carts and FIRST made an effort to control those, but I'm thinking it wasn't too successful.

Then you have to look at why you would even want to put a siren on the robot. I see it as just being an annoyance and a waste of time.
