What is the proper sequence of operation for supply and exhaust in a commercial hood equipped with a dry chemical extinguishing system when the extinguishing system is set off.
Please site NFPA article numbers.

I don't understand your question?

NFPA 96 - Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, the NFPA 17 - Standard for Dry Chemical Extinguishing Systems, UL Standard 300 - Fire Testing of Fire Extinguishing Systems for Protection of restaurant Cooking Areas.
