Which standards are commonly cited for fire alarm system installation in Illinois?

• A. NFPA 101 and NFPA 13
• B. ISO 9001 and ISO 14001
• C. NFPA 72 (Fire Alarm Signaling) and NFPA 70 (National Electrical Code), along with local adopted codes
• D. NFPA 25 and NFPA 72

Answer: (C)

The standards cited for fire alarm system installation in Illinois are NFPA 72 for fire alarm signaling and NFPA 70 for electrical installations, together with local adopted codes. NFPA 72 sets the requirements for how a fire alarm system should be designed, installed, tested, and maintained—covering initiating devices, notification appliances, control panels, signaling, monitoring, and system performance. NFPA 70 provides the electrical safety rules for wiring, circuits, grounding, conductor sizing, and protection of electrical power that feeds the fire alarm equipment. Local adopted codes bring in jurisdiction-specific amendments and requirements that the authority having jurisdiction enforces, ensuring the installation meets regional safety and code practices.

Other standards don’t fit the scope of installing fire alarm systems. For example, NFPA 101 focuses on life safety in general rather than the technical installation of fire alarm systems, NFPA 13 deals with sprinkler systems, and NFPA 25 covers inspection and maintenance of water-based extinguishing systems. International ISO standards aren’t typically the basis for U.S. fire alarm installations in Illinois, where NFPA standards and local codes prevail.
