CLASS N CIRCUITS? Deciphering the Fire Alarm Circuit Alphabet

 Class A, Class B, Class C, Class X . . . The current edition of NFPA 72, National Fire Alarm and Signaling Code, contains information on a myriad of circuit types and designations, including recently added, Class N circuits. Which type of circuit is required and where? What is the “best” class/type of circuit? What are the performance requirements for each type of circuit? How do I know the classification of an installed circuit. This presentation will review each of the fire alarm circuits designated in NFPA 72 and will explain the differences, performance requirements, and use of each, including the latest circuit designation, Class N.
