Does electrical panel, ups serves K-12 tornado storm shelter needs to be located inside storm shelter boundary and need a dedicated room? ICC 500 code does not include the information regarding elec. room.

Not per the NEC. There may be another NFPA standard that addresses

Yes, everthing required for emergency power including the "UPS" has to be inside the storm shelter, and it needs a 2 hour runtime for a tornado shelter. The standard 90 min isn't enough. (Or it needs protection equivalent to the storm shelter).

I think hurricane shelters need 24 or 48 hours runtime, but I not sure since we don't have too many hurricanes in the middle of the country.

And it can't be a "UPS". It has to be a UL 924 listed emergency lighting inverter.

That would all seem quite logical.

Does a separate/dedicated electrical room need inside storm shelter for panel and UPS or they can be located anywhere in storm shelter?
