Pioneer DDJ-SZ link CDJ2000

Hi. Guys I would like to link DDJ-SZ and 2xCDJ2000 and mixer 900 but on two tables. So on first table CDJ2000 and mixer 900 and on second table DDJ-SZ. We want to make a competition like a DJ Battle. How to link it ?

For example once  DJ on DDJ-SZ finishing his mix after 10min , DJ on CDJ 2000 could operate SZ from his CDJ ? and the other way ? 

How to connect it ? 

Cheers
