Re: History Lesson - Spray Sprinklers become the Standard
EWe have automatic sprinkler heads, and we have automatic sprinkler heads , and we have automatic sprinkler systems, and we have automatic systems with open heads (holes), but we also have manual systems with open heads or simply just holes. I believe the first edition of NFPA 13 came out in 1905 and was actually NFBU (?) 1. I have a handbook from 1914 talking about assigning dedicated personal to turning on valves. And as I've related we have manual systems with automatic heads in several buildings in Seattle, as well as manual exposure protection systems that I doubt any dedicated person is assigned to operate.

RE: History Lesson - Spray Sprinklers become the Standard
In our specialty freezer systems, we have less than 30 seconds to bring the four most remote sprinklers up to their operating pressure. Once they catch fire, the commodities in a freezer- and the freezer itself, depending on integrity of sheathing and interior insulation components, burn quite well. It would be tough to expect we'd be able to meet this performance-based design criteria with a manual system, BTW we've got trip time on the preaction valve down below 4 seconds. Thom is fine, he routinely calls/emails to check my output. Its still strong. I'll tell you why I don't trust manual systems. On the eve of 9/11 my wife and I were finishing up dinner at about 10 PM when the FA sounded. Now you'd think on this particularly day, we'd have the most awesome awareness of death and destruction, and maybe it would sink into people's heads that if you understand there could be a fire, it might be a good idea TO GET THE HECK OUT OF THE BUILDING!!! (or as Roland puts it, RUN LIKE HELL!!!) Nope, we were the ONLY people to get up and walk out. Further, we were alone, from what we could see, in the area surrounding the hotel tower that was atop the restaurant.

It was tempting to discuss the situation with the other diners, but somehow, I refrained from frustrating my spouse and self. It taught me that you can NEVER rely on anyone doing anything when an alarm or light or electric shock is presented as a stimulus. I might relent and allow a cold-weather valve.maybe.

Re: History Lesson - Spray Sprinklers become the Standard
In Seattle the University of Washington used to be north of the city in what is now the very heart (the Four Seasons Hotel now occupies the original site). When this became too valuable a property and too small also the University was moved to a site north and ast of Lake Union. There are buildings in the U District that have basement only systems with closed heads and without automatic water supplies. Presumably the fire department was supposed to hook up to the FDC and supply the water. There are also buildings in the International District, directly east and adjoining the original city with the same configuration. There are also older buildings with a head the size of a potato with 1 1/2 connections that have tits protruding at angles from the body shot small streams of water while the body rotates. Most of these have been poached over the years and the systemsabandoned. There was obviously a time when automatic was not important. If I decide to care I'll see if I can find when the requirement for an automatic water supply crept into the code. I don't think there is a requirement that a system needs to be automatic in operation.

RE: History Lesson - Spray Sprinklers become the Standard
Given the fact that the 1953 edition refered to the original as spray sprinklers (the original being the kind that sent spray up and down), we could say that both are spray sprinklers. We just started using the term spray when Mr. Thompson from FM started researching the new style deflector that sent all of the spray down. It was discovered that enough water was sent to the deck through evaporation and rising heat that it was not necessary to spray water up to the deck. Using all of the energy to send the water down, allowed for better spacing. Standard Spray also can said to have an attribute described as a certain size water droplet (don't have access to my books just now.. between x y microns, perhaps???). The committee therefore named the new sprinkler style as the Standard Spray Sprinkler (and THAT is what the SS is for). And then renamed the original sprinkler to be known as the conventional sprinkler (the industry naturally started to use the phrase old style because we are now using a 'new style'). SSU = Standard Spray Upright SSP = Standard Spray Pendent It should be recognized that the above is my opinion as a member of the NFPA, and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects and should therefore not be considered, nor relied upon, as the official position of the the NFPA, nor any of their technical committees.
