NFPA 72
National Fire Alarm and Signaling Code
2019
Edition
Expanded and
updated, the 2019 NFPA 72®, National Fire
Alarm and Signaling Code® reflects the latest technologies,
applications, and research.
Update to the new benchmark for fire alarm
systems, with requirements that reflect code user needs and concerns
in the field today. The 2019 edition of NFPA 72, National Fire Alarm
and Signaling Code presents 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).
This edition features important updates for
designers, installers, and AHJs—from added testing requirements for
Energy Storage Systems (ESS), to new requirements for HVLS fans and
air-sampling smoke detectors.
In a major change to scope, NFPA 72 now
addresses carbon monoxide protection.
Material
previously in NFPA 720, Standard for the Installation of Carbon
Monoxide (CO) Detection and Warning Equipment is relocated into the
2019 edition of NFPA 72. Critical requirements are incorporated
into:
- Chapter 17 for carbon monoxide detectors
- Chapter 14 for installation, testing, and
maintenance
- Chapter 29 for carbon monoxide alarms --
with a significant amount of additional information
- New Annex H
Other key changes
address occupant evacuation, areas of refuge, and VRLA batteries:
- Major revisions to the requirements for
fire service access elevators and occupant evacuation elevators
(OEE) coordinate with changes made in ASME A17.1/CSA B44. Annex
text is added for clarification.
- Extensively revised requirements for
occupant evacuation operation (OEO) coordinate with the new best
practices and field research.
- In addition to revised requirements for
area of refuge (area of rescue assistance), Chapter 24 now
includes requirements for stairway communications systems,
elevator landing communications systems, and occupant evacuation
elevator lobby communications systems.
- Chapter 14, Inspection, Testing, and
Maintenance now incorporates valve-regulated lead-acid (VRLA)
batteries.
- New and updated definitions bring NFPA 72
up-to-date with current technologies. For example, the terms
strobe, light, and visible are changed to visual notification
appliance, recognizing use of LED products that can be used for
fire alarm.
The 2019 edition of NFPA 72 is a
must-have resource for everyone involved with fire alarm design,
installation, inspection, and maintenance
