MK133 for 2 Teams

I currently have one MK133 built and working.
My question is how to have two MK133 for teams so that the first pressed MK133 will lock out the second?

Instructions are on the top of the board.

Thank you for responding. I understand that this is how you connect 2 boards for 8 players. What I did not know is, if a board is triggered, does only it’s corresponding LD5 light up and not the LD5 of the other board?

I’m not sure about LD5.
Maybe someone else knows.
