A fire sprinkler system is an active fire protection method, consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system, to which fire sprinklers are connected. Although initially used only in factories and large commercial buildings, systems for homes and small buildings are now available ...
The committee's initial report evolved into NFPA 13, Standard for the Installation of Sprinkler Systems, the most widely used fire sprinkler standard. [ 6 ] Around 1904, the NFPA began to expand its membership from affiliates of fire insurance companies to many other organizations and individuals, and also expanded its mission beyond ...
The 2002 edition of the NFPA #13 standard, section 3.6.1 defines quick response sprinklers as having a response time index (RTI) of 50 (meter-seconds) 1/2 or less. RTI is a measure of how thermally responsive the heat-responsive element of the sprinkler is, measured as the time needed to raise the temperature of the sprinkler bulb to 63% of the ...
Sprinkler systems installed by sprinkler fitters can include the underground supply as well as integrated overhead piping systems and standpipes. The fire suppression piping may contain water, air (in a dry system), antifreeze, gas or chemicals as in a hood system, or a mixture producing fire retardant foam .
The hydraulic calculation procedure is defined in the applicable reference model codes such as that published by the US-based National Fire Protection Association (NFPA), [2] or the EN 12845 standard, Fixed firefighting system – Automatic sprinkler systems – Design, installation and maintenance.

Active fire protection (AFP) is an integral part of fire protection. AFP is characterized by items and/or systems , which require a certain amount of motion and response in order to work, contrary to passive fire protection .
The area is described in this pdf on page 13-74 in the section 9.3.5.6.2. As I understand it, Sprinkler projects in California (and perhaps other states using NFPA 13) require an ADJ or government web site to provide the S sub s that is used to enhance the sprinkler system based on Seismic maps and the tables and calculations shown in the PDF File.
Fire protection is the study and practice of mitigating the unwanted effects of potentially destructive fires. [ 1 ] [ 2 ] It involves the study of the behaviour, compartmentalisation , suppression and investigation of fire and its related emergencies, as well as the research and development, production, testing and application of mitigating ...
