The 2019 edition of NFPA 72®, National Fire Alarm and Signaling Code, represents the culmination of over a century of signaling standards.

The traditional role of fire alarm systems is rapidly evolving. Now, the benchmark for fire alarm systems has changed to give designers, engineers, contractors, installers, and inspectors rules that reflect the current state of the field. An industry milestone, the 2018 edition of NFPA 72: National Fire Alarm and Signaling Code has the most advanced provisions ever developed for the application, installation, location, performance, and inspection, testing, and maintenance of fire alarm and emergency communications systems -- including Mass Notification Systems (MNS). A special task group on networks addressed the risk analysis, design, application, installation, and performance of networks and networking equipment in fire alarm systems, fire EVACS, and MNS. As a result of their findings, NFPA 72 includes a new circuit designation called Class N pathways permitting the use of networks and Ethernet when interconnecting a fire alarm system. Other changes help you avoid the loss of critical coverage and ensure system interfaces function correctly.Get the facts you need to work confidently and correctly. Engineers, contractors, consultants, designers, architects, and AHJs will be more efficient and effective with reliable support and expert insights that are only available in the 2018 National Fire Alarm and Signaling Code Handbook.
