Course Description
NFPA 72 2010 Fire Alarm & Signaling Code Updates (FAS106)
There was an extensive update of all sections of the NFPA 72 Fire Alarm and
Signaling Code from 2007 to 2010 and we cover the various updates and
changes. A highlight of the new format and the chapter 24 that is dedicated to
emergency communication is covered in depth. From wiring classifications to
intelligibility we dig into the details to keep you up to date on the changes that
affect system design and application.
Learning Objectives
1. Identify key code sections to consider for future designs.
2. How to plan for future and existing building life safety systems
3. Outline and survey existing infrastructure for proper communication
4. Understanding of how the new code is developed to be more than just fire
alarm

performance, inspection, testing and maintenance of
fire alarm systems, fire warning equipment, and
emergency communication systems and their
components.
• Emergency Communications Systems shall be
classified as follows:
• In Building Emergency Communications Systems
• In Building Mass Notification Systems
• Wide Area Mass Notification Systems
• Distributed Recipient Mass Notification Systems
Two Way Emergency Communication Systems
• In Chapter 3-Definitions, there are 74 new definitions
• Chapter 10 is now to be called Fundamentals

Page 21 EngineeringAdvantage™
Chapters 10 New Fundamentals
10.15 Protection of Fire Alarm Systems
• The exception has been removed in 10.15. This
allowed that there be no smoke or heat detector
protecting the FACU or power supplies if the building
was fully sprinklered. Detection is required in ALL
conditions
• Record of Completion is completely revised
to 12 pages
• 10.18.2.1.2.7 Completion Drawings, to be located
at the main FACU or location identified at FACU,
and storage cabinet must be labeled.

Chapter 17 Initiating Devices
• 17.4.6 Initiating devices shall be installed in all areas,
compartments, or locations where required by other
NFPA codes and standards or as required by other
governing laws, codes, or standards
• This replaces AHJ, and has been added through the
body of NFPA 72®.

Page 25 EngineeringAdvantage™
Chapter 17 Initiating Devices (cont.)
• Changes have been made to the criteria in 17.7.1.11
regarding protection during construction into 3
separate paragraphs as follows:
"Protection during construction
• Where detectors are installed for signal initiation
during construction, they shall be cleaned and
verified to be operating in accordance with the
listed sensitivity or replaced, prior to the final
commissioning of the system. (17.7.1.11.1)
• Where detectors are installed but not operational during construction,
they shall be protected from construction debris, dust, dirt and damage
in accordance with the manufacturer's recommendations. (17.7.1.11.2)
• Where detection is not required during construction they shall not be
installed until after all other construction trades have completed
clean-up.“ (17.7.1.11.3)
© Siemens Industry, Inc. All rights reserved.
Page 26 EngineeringAdvantage™
Chapter 17 Initiating Devices (cont.)
• The TC adopted new language for section
17.7.3.2.3.1 that was the object of the TIA on the last
edition [2007]. The new language:
• 17.7.3.2.3.1. "In the absence of specific
performance-based design criteria, smoke
detectors shall be located using a nominal
30 foot spacing."
• A. 17.7.3.2.3.1. "For the purposes of this section a
"nominal 30 foot spacing" shall be deemed to be
30 feet +/- 5% (+/- 1.5 feet)."
• This language seemed to address the problem
that "shall be permitted to be 30 feet" does not
preclude any other distance yet instructs the AHJ
to allow some latitude in the enforcement.

sidewall, between the ceiling and 12 in.
(300 mm) down from the ceiling to the
top of the detector.

Emergency Communications Systems
Scope
• 24.2.1 The systems covered under Chapter 24
are for the protection of life by indicating the
existence of an emergency situation and
communicating information necessary to facilitate
an appropriate response and action.
• 24.2.2 This chapter establishes minimum required
levels of performance, reliability, and quality of
installation for emergency communications
systems but does not establish the only methods
by which these requirements are to be achieved.

Page 67 EngineeringAdvantage™
Emergency Communications Systems
Key Areas
• Intended to communicate information about
emergencies including but not limited to fire,
terrorist activities, other dangerous situations,
accidents, and natural disaster
• Requires intelligible voice messages
• Ancillary functions including the use of the system
for general paging, background music and other
non-emergency functions are permitted provided
they don't interfere with emergency performance
requirements.

Traditional Fire Voice/Alarm Evacuation System
• Permits a mass notification control unit to take
control of fire alarm notification appliances
including amplifiers, speakers, and strobes
• Survivability requirements to reference new
chapter
• Will require a tone and visible indication any time
the priority is granted to the mass notification
control unit
• "Intelligibility" is required for ALL voice messages
• Strobes used for dual purposes shall not be
marked 'FIRE', strobes to be blank or 'ALERT'

MASS Notification in Building
History of MNS and NFPA
• June 2003 Air Force Civil Engineering Support Agency petitioned NFPA to
develop a standard for Mass Notification
• NFAC TCC was charged with the task for reviewing the request
• NFAC TCC Task Group was formed in February 2004
• First Task Group Meeting was held March 2004
• Subsequent meetings took place in May and August of 2004
• NFPA 72-2010 with Chapter 24 on ECS/MNS was approved August 2009

MASS Notification in Building
• 24.4.2.2 Risk Analysis for Mass Notification Systems
• 24.4.2.2.1 Each application of a mass notification system shall be specific
to the nature and anticipated risks of each facility for which it is designed.
• 24.4.1.6.2 Speakers used as alarm notification appliances on fire alarm
systems shall also be permitted to be used for mass notification.
• 24.4.1.7.1* Notification appliances required to provide special suppression
pre-discharge notification shall not be overridden by other systems.

MASS Notification in Building
• Operation of MNS system is
based on the Emergency
Response Plan
• Intelligibility of voice messages
are required to meet the
requirements of chapter 18
(notification)
• Visual notification to be
completed through strobes,
textual, graphic or video displays
• Re-labeling of existing strobes
labeled fire is required to be
completed in a manufacturer's
approved method
