Modern commercial lighting is installed with two connections: always on power, and then some kind of control. Either a data cable, or 0-10 volt wiring, or some kind of wireless thing. When the control method is not connected (or malfunctioning), the lights default to on for safety.

Ah, I see. Probably one of the first two, I feel like wireless capability for 7000 lights would be ridiculously expensive.

Edit: Possibly panel mounted pots for the second option instead of switches.
