title: NFPA 72
text: # NFPA 72
  
  The NFPA 72 (National Fire Alarm and Signaling Code) is a standard published by the National Fire Protection Association every 3 years for installation of fire alarm systems and emergency communication systems in the United States.
  
  ## Purpose
  
  The NFPA 72 "covers the application, installation, location, performance, inspection, testing, and maintenance of fire alarm systems, supervising station alarm systems, public emergency alarm reporting systems, fire warning equipment and emergency communications systems (ECS), and their components." Federal, state, and local municipalities across the United States have adopted the NFPA 72 as a standard in the enforcement of fire code regulation. Municipalities often adopt revisions of the code after years of review and amendments, making many local fire codes specific to their governing authorities.
