NFPA 72-2010 CHANGES PART I; Chapter 1 and 2 
Arguably, the biggest change in NFPA 72-2010 edition is its new name, 
National Fire Alarm and Signaling Code. The next, most obvious change 
is the new chapters, many of which are reserved.  It is not possible 
to present these changes using the plain text used in this newsletter.
To read my review of the changes, please download it from here:
An excerpt from the forward summarizes some of the changes:
"The 2010 edition of the Code presents a major change in the scope and
organization of the document. This is reflected in the new title, 
National Fire Alarm and Signaling Code. The broader scope of the Code 
includes emergency communications systems in addition to the 
traditional scope of fire alarm systems. A new chapter on emergency 
communications systems (ECS) has been added to provide requirements 
for a variety of systems used for communication of information in 
various emergency situations. The ECS chapter includes new systems 
such as in-building mass notification systems, wide-area mass 
notification systems, distributed recipient mass notifications 
systems, two-way radio communications enhancement system, and area of 
refuge emergency communications systems. The ECS chapter also includes
two systems formerly located in the chapter on protected premises fire
alarm systems: (in-building fire) emergency voice/alarm communications
systems, and two-way in-building wired (telephone) emergency services 
communication systems.
"Two other new chapters have also been added in the 2010 edition. The 
new chapter on circuits and pathways includes requirements and 
information formerly from the chapters on fundamentals of fire alarm 
systems and from the chapter on protected premises fire alarm systems. 
This new chapter provides circuit and pathway performance (class) 
designations and pathway survivability level designations as well as 
general wiring requirements presented in a format that will allow use 
by any type of system covered in the Code. The new chapter on 
emergency control functions and interfaces includes requirements and 
information formerly contained in the chapter of protected premises 
fire alarm systems. In this chapter the term "fire safety function" 
has generally been replaced with the term "emergency control function"
to reflect the potentially broader application beyond just fire alarm 
systems. This new chapter also includes new provisions for 
first-responder-use elevators and elevators for occupant controlled 

"The 2010 edition has been substantially reorganized to accommodate 
the new chapters in a logical order with reserved chapter numbers 
included to minimize the potential for further renumbering in the 

"The overall organization includes administrative chapters, support 
chapters, and system chapters as well as numerous annexes for 
"Significant revisions have also been made throughout the 2010 edition
to reflect the broader application of the Code to emergency 
communication systems. These include revisions within the chapter on 
fundamentals to address power supply requirements, signal priorities, 
signal distinction and documentation requirements; revisions to the 
protected premises chapter to better accommodate non-fire alarm 
systems in combination systems; revisions to the supervising stations 
chapter and public emergency reporting system chapter to allow their 
use for emergency communications systems; and revisions to the testing
and maintenance chapter to incorporate requirements for the 
inspection, testing, and maintenance of mass notification systems and 
two-way radio communications enhancement systems.
"In addition to the content of the new chapters, the 2010 edition 
includes significant technical changes. These include new requirements
for signaling to the deaf and hard of hearing, new requirements and 
guidance for the design, installation, and testing of voice 
communications systems to ensure voice intelligibility, and extensive 
revision of requirements for the installation of smoke detectors in 
both level and sloped joist and beam ceiling applications.
"Revisions to the supervising station chapter in the 2010 edition 
include the retirement of four legacy transmission technologies no 
longer being installed: active multiplex transmission systems, 
McCulloh systems, directly connected noncoded systems, and private 
microwave systems. The subsection on "Other Transmission Technologies"

has been relocated to become the default subsection for supervising 
stations communications methods.
"Modifications in the 2010 edition to the chapter on single- and 
multiple-station alarms and household fire alarms systems include new 
provisions to address the interconnection of smoke alarms using 
wireless technology, new provisions for signaling to those with 
hearing loss, and new requirements and guidance for the placement of 
smoke alarms and smoke detectors.
"The 2010 edition includes two new guidance annexes, Annex C on system
performance and design, and Annex D on speech intelligibility.
"Prior editions of this document have been translated into languages
other than English, including Spanish."
