M05 ­Fire Detection Performance and Requirements in High Airflow Environments (Data Centers & Telecommunications) (PDF, 1.8 MB)
Presenter(s): David Quirk, Verizon Wireless
Current NFPA requirements for fire detection in high airflow environments do not properly address current available detection technology, the introduction of aisle containment systems, or the increasing air velocities and air change rates (current standards limited to 60 ACH) in electronic technology spaces such as data centers and telecommunication facilities. This session will cover current considerations, current NFPA requirements, industry research status, and status of work by a joint NFPA 75/NFPA 76 task group for detection in high airflow environments.

M11 ­Smoke Alarm Response and Tenability in Residential Structures
 Thomas Fabian, UL LLC
The session will discuss smoke alarm response to ventilation-limited flashover fires, smoldering and flaming fires originating from upholstered furniture and bedding, and kitchen cooking fires in a traditional, single-story ranch house and a contemporary, two-story, open floor plan house. Commercially available UL 217 compliant smoke alarms (conventional ionization and photoelectric, ionization-photoelectric, ionization-carbon monoxide, photoelectric- carbon monoxide, and advanced algorithm ionization) were spaced throughout houses following NFPA 72®, National Fire Alarm and Signaling Code, guidelines. Smoke obscuration, gas concentrations, and temperatures along the path of occupant egress were characterized to assess occupant tenability. Required Safe Egress Times (RSETs) for occupants located in and remote from the room of fire origin were compared to Available Safe Egress Times (ASETs) calculated for the various alarm activation times in the different fire scenarios.

M29 ­Parameters for Indirect Viewing of Visual Signals Used in Emergency Notification (PDF, 59 KB)
Presenter(s): John Bullough, Rensselaer Polytechnic Institute 
Recent research performed for the Fire Protection Research Foundation at the Lighting Research Center at Rensselaer Polytechnic Institute suggested that effective intensity, the current metric used to characterize the photometric performance of visual signals, may not be predictive of visual detection of signal lights when these are viewed indirectly or in the far-peripheral field of view. Based on previous studies by others, RPI suggested that a flashing light should increase the illuminance on the opposite wall by at least 7% in order for this increase to be detected reliably. This estimate has not been validated. In the recent Foundation study, RPI also conjectured that colored light (e.g., red) might be used for indirect visual signaling and that an even smaller increase in vertical illuminance from colored light might be sufficient to be detected reliably. Accordingly, the Foundation and RPI LRC are undertaking a project with the primary goal of identifying whether the 7% increase in light level can be reliably detected by observers with normal vision. A secondary goal is to explore the impacts of colored light.

M50 ­Mass Notification System Maintenance — A College Perspective 
Track(s): Detection & Notification, Emergency Preparedness/Business Continuity
Presenter(s): David Sylvester, Seneca College of Applied Arts and Technology
Mass notification systems (MNS) have the capability to provide real-time information and instructions to people during emergency situations for the protection of life. In order for MNS to operate as intended, it is critical that a proper maintenance program be implemented to ensure the performance of the system during an emergency incident. Right at the beginning of the project, Seneca College’s facilities management team provided direction regarding the maintainability and serviceability requirements for their MNS solution. This presentation addresses the ongoing maintenance challenges and lessons learned at Seneca College in Toronto, Ontario, Canada. Seneca College implemented their mass notification system in 2010 at four campuses located across the Greater Toronto Area. These campus locations serve a student population of approximately 100,000 students. Sponsors: Building Fire Safety Systems Section, Fire Science and Technology Educators Section

T16 Electrical Transformer Fire Detection & Suppression (PDF, 2.2 MB)
Presenter(s): Kevin Mowle, Bruce Power
At most power utilities, the frequency of transformer fires is increasing due to age and fatigue. This session will give an example of a recently upgraded installation utilizing linear heat detection, deluge fire suppression, and a water curtain fire barrier.

T18 ­2013 National Fire Alarm and Signaling Code — Changes (PDF, 1 MB)
Presenter(s): Warren Olsen, FSCI
This session presents some of the significant changes made to the National Fire Alarm Code to produce the 2013 edition. The presentation explains the changes and the reasons they were made. In addition, examples show the impact of the code changes. Some of the changes include the following: new Chapter 7, Documentation; personnel qualifications; reorganization of inspection, testing, and maintenance requirements; emergency control function interfaces; limitations on the number of addressable devices on signaling line circuits; opt-in alarm verification for signals sent to a supervising station; and allowable transmission methods.

T42 ­Flame Detection for Silane and Other Pyrophoric Non-Hydrocarbon Fires (PDF, 5.1 MB)
Presenter(s): Jonathan Eisenberg and Ernesto Vega Janica, Rolf Jensen & Associates
Our research is based on technical provisions of NFPA 318, Standard for the Protection of Semiconductor Fabrication Facilities, and ANSI/CGA standards as approved methods for the protection of semiconductor fabrication facilities for bulk silane storage and handling. In this session, a real case scenario is examined under Code regulations and possible detection system layouts are analyzed. Our lessons learned are also discussed.

T69 ­Fire Alarm System Documentation Requirements – Understanding the New Chapter 7 (PDF, 292 KB)
Merton Bunker, U.S. Department of State
Fire alarm system documentation is essential to the proper installation, inspection, testing, and maintenance of fire alarm systems. A new Chapter 7 was added to NFPA 72®, National Fire Alarm and Signaling Code, in the 2013 edition. This session will cover the new requirements in detail. This session will also explain the different types of documentation required by the new Code and use examples of actual documentation to reinforce learning objectives.

W23 Performance Based Design: Fire Alarm Visual Notification Appliances — Mathematical Guide (PDF, 4 MB)
Presenter(s): Ernesto Vega Janica, Rolf Jensen & Associates 
As there is no process for certifying alternative methods, except in transportation facilities under DOT enforcement, a mathematical guide program has been developed by which engineers can demonstrate fire alarm visual notification coverage equivalent facilitation in the event of irregular (non square) rooms and other challenging projects not listed on the prescriptive tables from NFPA 72Ò, National Fire Alarm and Signaling Code. The technical provisions from UL Standard for Safety 1971, Signaling Devices for the Hearing Impaired, are used as an approved performance based criteria in lieu of the requirements found in chapter 18 on notification appliances.

W40 Notification Appliance Requirements of NFPA 72, 2013 Edition (PDF, 113 KB)
Track(s): Codes & Standards, Detection & Notification 
Presenter(s): Ray Grill, ARUP
There have been a number of changes made to the requirements for designing both audible and visible notification appliances in Chapter 18 of NFPA 72®, National Fire Alarm and Signaling Code. This session will review the changes and discuss the impact of these changes on fire alarm system design. Examples of ways to incorporate these new requirements will also be reviewed.
