Fire Pump Room - Electrical panel and Transformer in same room?

[Dark Sparky]

Large building with separate Fire Pump Bldg located out in the parking lot. Fire Pump Bldg has 3 rooms - largest for fire pump, etc. - the other 2 rooms are a Restroom and a Janitor's Closet (both w/ their own outside entrances). There is a 480/277V panel, a 480-120/208V transformer, and a 208/120V panel - all located in the fire pump room. These feed loads including the Diesel Fire Pump Controller, a fire system jockey pump, a subpanel in a non-related bldg, and other non-fire loads.

Can the 2 panels and xfmr be located in the fire pump room? Code references? Looking for *any* code references - NEC, other NFPA codes, or any others - that may apply.

Thank you.

See below. The one you are most interested in is 4.12.1.1.4. The question being is it essential to the Fire Pump? Sounds like an AHJ question for sure but this should help.
