Fire Protection System Requirement for 1600 kv Oil Type Transformer

It is understood that 1600 kv oil type transformer is considered high hazard but I can’t find code reference for fire protection system requirements. The transformer room is part of building structure. NFPA 70 required minimum 3 hour fire rated enclosure and permitted to reduce it to 1 hour if the room provided with automatic sprinkler, water spray carbon dioxide, or halon. Does that mean a fire protection system is not mandatory in the 1600kv oil transformer?

Thanks for your time and support.
