I need a way to disconnect the panel boards in a line side tap if the building main breaker were to trip (requirement from the fire marshal).

I was thinking:
*shunt trip at the 2 panel boards with shunt trip and auxiliary contacts connected to a mini power zone
*mini power zone being powered from the building switchboard before the building main disconnect

So, when the building's disconnect switch is pulled, it disconnects power to the mini power zone which trips the auxiliary contacts in the panel boards: disconnecting the panel boards.


Is this a viable plan or is there a better option, if this is a decent course what are some potential downfalls I can encounter.(using NEC 2011)

I'm fairly inexperienced in the solar world, so any help would be greatly appreciated.
