Talk:Fire sprinkler system

message: The section on water mist fire protection systems is just not correct:
If water damage or water volume is of particular concern, a technique called Water Mist Fire Suppression may be an alternative. This technology has been under development for over 50 years. It hasn't entered general use, but is gaining some acceptance on ships and in a few residential applications. Mist suppression systems work by lowering the temperature of a burning area through evaporation rather than "soaking". As such, they may be designed to only slow the spread of a fire and not extinguish it. Some tests, that may or may not be biased, showed the cost of resulting fire and water damage with such a system installed to be dramatically less that conventional sprinkler systems.
Water mist fire protection systems are not just selected where water damage or water volume is a particular concern, although this is one of the features of water mist. It has entered general use and now the major fire giants all have water mist systems... it is fully approved on ships for most areas (accomodation, machinery rooms, galley areas, bilge etc etc), and most new cruise ships are fitted with this system... many thousands of land applications are already protected by water mist systems... lowering the temperature is just one of the mechanisms used in fighting the fire (also local oxygen inerting and radiant heat blocking and to a lesser extent the soaking as well)... they are not designed to slow the spread of the fire, some are designed for suppression and control, some for extinguishment... the biased or not statement is a bit ridiculous!

message: How about some information on new or alternate types of fire sprinklers? Like a "dry fire suppression system" that uses gasses? (something like http://www.e1.greatlakes.com/wfp/product/jsp/fm200_works.jsp ) Or the water wall method that I heard was popular at trade shows here is a good link to some different types of fire suppression systems ( http://www.uos.harvard.edu/ehs/ih_fire_detection.shtml ) and some reasons to use or not use Gas ( http://searchdatacenter.techtarget.com/columnItem/0,294698,sid80_gci1148917,00.html ) I think it might be good to consider starting a page for Fire Suppression Systems that could link to this page and others that exist like Gaseous fire suppression already Andrew Powell 20:44, 21 February 2006 (UTC)

message: I added a to the page that Wood's metal is used as a fusible metal, which is now marked as . Why? Several other Wikipedia articles mention this, and a web search for sprinkler "wood's metal" yields hundreds of hits. Maybe it should be rephrased as fusible metal (often Wood's metal) since also Field's metal seems to be used. Han-Kwang (t) 15:11, 16 May 2008 (UTC)

message: I would think that the air leaving the system via the activated sprinkler head would add oxygen to the fire causing it to grow even larger.  Is this yet another disadvantage to these systems or are they filled not with air but with nitrogen or some other inert gas?  --Pascal666 (talk) 00:09, 18 August 2008 (UTC)
replies: text: There is more than ample oxygen available to the fire from the surrounding atmosphere, the relatively small amount of air in the piping does not affect the fire at all. Kilmer-san (talk) 03:51, 18 August 2008 (UTC)

message: This article from January 12th looks interesting and relevant, but I'm not sure how to work it into our article.  It is about a proposal to add a sprinkler requirement to the Minnesota building code, and discusses the relative benefits of sprinklers versus smoke alarms, increasing the cost of housing versus housing affordability, and cost per life saved.

replies: text: I couldn't readily find the article you linked...was it concerning residential sprinklers? The ICC has approved the requirement of residential fire sprinklers for all new one and two family homes and townhouses. Atuuschaaw (talk) 15:31, 27 January 2009 (UTC)
thread_title:  Useful? 

message: In Boston, I have observed that new fire sprinkler systems in multistory commercial buildings have some kind of major backup pump, usually installed in the basement or a utility space on the ground floor.  The backup system consists of a large diesel engine, an array of lead-acid batteries to start it, a fuel oil tank, and an alarm/control system.  There are provisions for combustion air intake and diesel exhaust, with ducting to the outside air.  I think there are requirements to start and run the engine briefly on some periodic basis, to verify that the system is operable.
Anyway, there does not seem to be much coverage of this aspect of fire sprinkler systems in the article.  I would write something, but I'm not yet knowledgeable enough about this, and hope that better-informed editors could add coverage of the topic to the article.

message: The article is very informative and allows an understanding of how the sprinkler system was introduced etc.. also the various types of sprinklers in use. As per the Indian Building Code it is now mandatory for all Malls,Hotels, High Rise buildings and offices, Hospitals etc to install an effective detection system as also an effective suppresion system, like the sprinkler system mentioned. I however would like an additional research to be done to find how many times and why the suppresion system did not work, even when there was a fire. Secondly, in the Wet Type, is there a need to periodically flush the sprinkler system so that it does not clog in case the presurrised water in the pipe is kept, say over a period of one year plus? If yes, how is it done? If not, why not?122.180.1.117 (talk) 10:09, 31 January 2013 (UTC)

message: With some help from someone in the industry, I would like to help with the addition of information about calculating C sub p as shown in the building code document NFPA 13 PDF file that I will provide the link to here. 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.

text:  Ok, sorry it took so long, I have pasted my best workup of an addition to the page to address "Seismic, OSHPD, and FM" factors which can modify the brace carrying capacity of fire sprinkler pipe and load. Please feel free to modify. 
START OF PASTE ------------------------------------
Generally speaking, Earthquake seismic factors are used to determine the required strength of the braces that carry the fire sprinkler system pipe and load. There are certain circumstances, determined by the adopted building code, by which the project is governed, that require the system to meet Seismic standards, and in which case, beside possible design factors, will require the acquisition of a parameter multiplier, used to modify the overall system pipe weight which will in turn modify the required brace load capacity.  And in such cases, this parameter, if not provided by the AHJ (Authority Having Jurisdiction), is provided by a Seismic map using the latitude and longitude of the project. There are also some cases where the system pipe weight is modified by a FM factor (Factory Mutual) determined by an insurance company. There is also a case where it is can be modified by a factor provided by OSHPD (office of statewide health planning and development) which applies to health care facilities where special care is needed.
