Local Building Inspectors would know the applicable codes. One starting point would be the National Fire Protection Association www.nfpa.org and the applicable codes. NFPA 75 Standard for the Protection of Information Technology Equipment NFPA 76 Recommended Practice for the Fire Protection of Telecommunications Facilities NFPA 70 National Electrical Code (Handbook has explanations) NFPA 101 Life Safety Code ?? not sure. NFPA 110 Standard for Emergency and Standby Power Systems
