Hi Nicky, The K34 Sprinklers are part of a larger fire protection strategy. That strategy counts on a philosophy known as "Surround and Drown" (a motto that manufacturers surely don't use in literature). The K34 is listed for use as a special application sprinkler and was designed and tested for cold storage applications. In fact, the section you site in FM 8-9 is titled Special Applications and the section specifically states that you have to use the system components that the sprinkler were tested with and that you must submit calculations showing conformance to those standards. That means that it is part of the QUELL delayed response, dry system. This requires use of the proprietary software to determine trip times and water-delivery times to show that you meet the requirements for this concept. It is my understanding that only Quell licensed contractors can participate in that program. Therefore, I don't think you'll not be able to purchase those heads for use without training and certification in this protection philosophy.
I hope you'll be able to find a strategy that works for your project. It should be recognized that the above is my opinion as a member of the NFPA 13 Committee, 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.

A ‘roof only’ solution – no in-rack sprinklers. This would be the Tyco TY9101 sprinkler. But apparently Tyco will only supply this sprinkler to accredited Quell/Vanquish installers here in New Zealand. Even an independent supplier of Tyco heads is advising they cannot get them. We only want to follow FM design, not use Tyco Quell/Vanquish system. Just wondering if anyone else has struck this issue?
