Smoke Detection TechnologyFire detection technology is one of the fastest-evolving areas of fire protection. Advances in sensors and electronics are applied every day in innovative ways to improve our ability to quickly detect fire and the products of combustion combustion, rapid chemical reaction of two or more substances with a characteristic liberation of heat and light; it is commonly called burning. The burning of a fuel (e.g., wood, coal, oil, or natural gas) in air is a familiar example of combustion. and to effectively notify occupants. NFPA NFPA National Fire Protection Association
NFPA National Food Processors Association
NFPA National Fluid Power Association
NFPA National Federation of Paralegal Associations (Edmonds, WA) 72®, National Fire Alarm Code®, is consequently in a state of rapid evolution as its technical committees work to develop requirements related to performance and installation of these new systems in new and challenging fire environments.
The Fire Protection Research Foundation has recently conducted a number of research projects in support of this evolution, including:
* New Technologies and Unique Applications: The Foundation has studied the performance of strobe strobe
1. A strobe light.
2. A stroboscope.
3. A spot of higher than normal intensity in the sweep of an indicator, as on a radar screen, used as a reference mark for determining distance. systems in big box spaces, video imaging technology in industrial spaces, carbon monoxide carbon monoxide, chemical compound, CO, a colorless, odorless, tasteless, extremely poisonous gas that is less dense than air under ordinary conditions. It is very slightly soluble in water and burns in air with a characteristic blue flame, producing carbon dioxide; detectors in commercial spaces, and a range of new and emerging detection technologies in roadway tunnel environments;
* Spacing Requirements in Unique Configurations: Four studies were undertaken to explore appropriate spacing for smoke detectors smoke detector
An alarm device that automatically detects the presence of smoke. Also called smoke alarm. in spaces with complex ceilings, including sloped ceilings and ceilings with deep beams and beam pockets;
* Notification Effectiveness of Alarm Signals: A series of studies on the ability of conventional and innovative alarm signals to awaken the elderly, the hard-of-hearing, and the hearing-impaired and to intelligently notify large groups in commercial settings provided new insights on the optimum signal for these at-risk groups;
* Characterizing Smoke to Enhance Detector Performance: Two studies-one to characterize the smoke from residential materials and the second to predict the ability of detection systems to respond to small, developing fires-are setting the stage for enhancements in smoke detection for today's fire environments.
Results of all these studies can be found on www.nfpa.org/foundation.
With this work and the work of others as background, the Foundation is embarking on two new projects to aid in the development of the next generation of detection and signaling systems. These projects are based on the concept that smoke detection systems operate as part of an overall fire-safety timeline that includes ignition ignition, apparatus for igniting a combustible mixture. The German engineer Nikolaus A. Otto, in his first gas engine, used flame ignition; another method was heating a metal tube to incandescence. , flame and smoke spread, fire protection system initiation, occupant occupant n. 1) someone living in a residence or using premises, as a tenant or owner. 2) a person who takes possession of real property or a thing which has no known owner, intending to gain ownership. (See: occupancy) notification, and occupant egress See ingress. .
The first project will focus on the early stages of fire detection, bringing together the studies on the characterization A rather long and fancy word for analyzing a system or process and measuring its "characteristics." For example, a Web characterization would yield the number of current sites on the Web, types of sites, annual growth, etc. of smoke and improved smoke transport prediction methods with aspects of the egress environment and escape time to develop performance metrics Performance metrics are measures of an organizations activities and performance. Performance metrics should support a range of stakeholder needs from customers, shareholders to employees . for the next-generation detector.
The second project focuses on signaling to transfer knowledge from other disciplines to the concept of the intelligent fire alarm signal, both to better inform building occupants and to integrate fire and security signaling!
The focus of the Foundation's work is to enhance the technical basis of NFPA codes and standards so that they can appropriately reflect the contributions that our new understanding of today's and tomorrow's products and systems can make to fire safety. The Foundation's Fire Detection and Alarm Research Council provides an opportunity for the community to participate in planning and conducting these research programs.
