Codes and Standards (NFPA 72, NFPA 70/NEC, NFPA 101, Alaska Fire Code)
Know which document governs what. NFPA 72 is the National Fire Alarm and Signaling Code: design, installation, testing, inspection, and maintenance of detection and signaling systems. NFPA 70 (NEC) governs electrical wiring, overcurrent protection, grounding, and Article 760 for fire alarm cable. NFPA 101 is the Life Safety Code: egress, occupancy classification, and where detection/notification is required. The Alaska Fire Code adopts these by reference with state and local amendments, and Alaska-specific conditions (remote villages, extreme cold, limited water supply, volunteer departments) shape local requirements. Questions may test that the Alaska Fire Code is adopted at the state level and that local jurisdictions may add requirements.
Traps: mixing up which standard owns a requirement. "Where must smoke detectors be installed?" is NFPA 72 and NFPA 101 territory, not NEC. "What cable type and overcurrent protection?" is NEC Article 760. "Is a second means of egress required?" is NFPA 101.
Remember NFPA 72 distinguishes installation (Chapter on fundamentals and circuits), inspection/testing/maintenance (its own chapters), and documentation requirements. Also know that the authority having jurisdiction (AHJ) enforces the code and may accept alternatives.
Rule of thumb: if it is about the building's life safety and egress, cite NFPA 101; if it is about the alarm system's design and testing, cite NFPA 72; if it is about the wire and power, cite NFPA 70.
Worked example: A question asks the minimum wire type for a fire alarm circuit. Answer from NEC Article 760, not NFPA 72.
