One Code, Many Chapters-Why you need to review all of NFPA 72 when planning and installing fire alarm systems

摘要

The requirements for fire alarm systems appear in all 15 interrelated chapters of NFPA 72~R, National Fire Alarm and Signaling Code. This comes as a surprise to some users of the code, who apparently believe that all the chapters stand alone. Although Chapter 29, "Single-and Multiple-Station Alarms and Household Fire Alarm Systems," is intended to stand alone, it also refers to the other chapters for guidance.
