Course Description

This one hour mass notification course addresses the major changes coming in the US Fire Code. For the first time, the 2010 version of the NFPA 72 National Fire Alarm and Signaling Code, and the recently published UL2572 standard, extend their scope beyond the realm of fire alarm to other life-safety systems and functions. In addition to simply indicating the existence of an emergency situation these new codes require instructions via voice communications and/or visible signals that include, text, graphics or other displayed communication methods. It will provide examples of how the effective use of MNS systems in buildings and campuses can enhance the safety and effectiveness of virtually any mass notification application.

Statistics to Remember

“Subjects had to choose between a normal exit and an emergency exit in different conditions. The results show that the majority of subjects choose the normal exit even if the distance is double. Findings show that a ring/tone signal is often misunderstood but, a spoken message is understandable.”

-Evacuating people from facilities during an emergency, Facilities Magazine, Lars Benthorn, Håkan Frantzich

…did not know what to do!

“It is estimated that the 60% of people that lose their lives in an emergency situation, do so because they did not know what to do.”

-International Disaster Institute

…a spoken message is understandable.

NFPA 72 2010 Integrates into the body of the code mass

notification systems (chapter 24) including their design criteria.

Is being currently used in some municipalities right now. Will be mainstream in 2013. Requires extensive risk analysis. Dictates intelligibility of the system.

UL 2572 Released November 2011. Standard covers equipment required for

mass notification in Chapter 24 of NFPA 72.

http://www.ul.com/?noredirect




The 2010 edition of the Code presents a major change in the scope and organization of the document. The broader scope 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.

NFPA Code Changes




What is a Mass Notification System?

According to the NFPA "...a system used to provide information and instructions to people in building(s) or other spaces using intelligible voice communications and visible signals, text, graphics, tactile, or other communication methods." To be effective it should: Inform - Alert the target population of what is happening and where. Provide instruction - Notification is only effective if it gives

direction on how to act or what to do. Verify - Critical communications require verification that messages

are heard, understood and acted upon. Repeat - Most people need to hear a message 3 times before they

react to it.




A speech intelligibility assessment for a public address system is an important component of NFPA 72. Intelligibility is characterized by the acoustics of a definable space and the performance of the sound system equipment.

The speech transmission index,

STI, has proven to be a valuable tool for such assessment. Designing for intelligibility takes the right tools, expertise, training and practice.




Intelligibility Influences Environment Room Finish

Flooring (Ceramic Tile, Carpet, Hardwood) Walls (Paneling, Gypsum Board, Curtains, Concrete, Glass) Ceiling (Lay-In, Gypsum Board, Concrete, Steel) Size (Cathedral, Open, Enclosed, etc) People (absorption)

Speaker Placement

Ceiling Column or Array Pendant Wall (Flush or Surface) Floor




Intelligibility Influences Intelligibility Testing Difference between Loudness & Intelligible Testing is required in both unoccupied and occupied space unless

specifically directed to do otherwise. Intelligibility is measured in either Common Intelligibility Scale (CIS),

> 0.7 usually required Trend is to measure in Sound Transmission Index Public Address

(STIPA), > 0.5 usually required Many methods have been used, make sure you know what is

expected… (from the AHJ)




Intelligibility Influences Audio Modeling (EASE) EASE – Enhanced Acoustic Simulator for Engineers EASE has been setting the worldwide standard for acoustic simulation

both inside rooms and in open areas. Rooms can be defined using a CAD module (3D), absorption

coefficients can be assigned to surfaces, and sound sources as well as listener positions can easily be added to the model.

Data can then be used to generate an exact simulation of reverberation times, speech intelligibility and other acoustical parameters even before the room itself is built.




Loudspeaker considerations Ceiling type, height and budget Speaker SPL and opening angle




EASE Audio Modeling Audio Modeling (Sample 1- Speaker Layout)




EASE Audio Modeling Audio Modeling (Sample 1 4000Hz)




EASE Audio Modeling Audio Modeling (Sample 1 STI)




EASE Audio Modeling Audio Modeling (Sample 2 Speaker Layout/Aiming)




Ceiling Loudspeaker Options - A solution for each ceiling type, height and budget




Other Requirements

Compliance with other Evacuation Standards International and local standards (IEC, UL, etc…) Off-shore standards (SOLAS)

Fully Redundant Redundant cabling (like computer systems) Automatic backup amplifier switching Backup 48 VDC power supply

Digital System/Component Supervision Control input and output (Speaker lines, microphones) Event and fault logging Equalization, Delay, Automatic Volume Control




Other Requirements

Communication Functionality Seamless Integration with other systems Simultaneous Calls and BGM, EVAC priority calls with up to

256 priority levels (12+ Simultaneous digital audio channels) Pre-recorded messages and chimes

Networked digital communication

Digital audio routing and interference free CD quality (CAT5/6, Optical fiber)

Scalable - easy, low cost installation and expansion by “daisy chaining” components, Easy to program regardless of size




Other Requirements

Integration with Digital Signage and/or SMS Texting Systems Required in many situations including education and

hearing impaired applications Provides video alerts to compliment audio alerts




What Does This Mean For You?

Understand what will be tested and who will test it? Sound Pressure Level (SPL) Coverage (is there sound in the right places) Intelligibility (can people understand clearly) The Authority Having Jurisdiction (AHJ) is responsible to make sure

the testing is complete and the system passes

The potential exists for third party testing companies, or for security or A/V systems integrators, to do this testing if they have the proper certifications according to the AHJ
