It’s a very customized retrofit situation. I’m aware of the MC w/ 16 or 18 awg control wires but this would not do me any good. The lights are controlled from a central MCU which is controlled by a building automation system. The power comes from several original lighting circuits on which the 3 and 4 way switches have been bypassed and blanked off. The control wire runs in a loop throughout the building and controls all the common area lighting.
The lights are pitch black when the control wires are shorted. Is there anything in the code requiring the power to be disconnected when it’s automated by a computer?

Tell me and I forget. Teach me and I remember. Involve me and I learn.
Some drivers turn off at 0v. Others output a low level light (1% or a programmable value). If shorting the control wires does not turn off the light, you need to open the AC feed to the driver to turn them off.
This controller, for example, provides the 0-10v control on the purple/grey wires and the switched line on the AC side (red wire)
