The reason for requiring QR is that we intend to protect a ceiling with 14 inch pockets. So we follow 8.6.7.2.(6) NFPA 13 ed 2013 that requires QR, and the exception for sprinklers in each pocket.
I got the reply from Tyco, the SW 20 and SW 24 are only available in standard response. -----Mensaje original----- De: Sprinklerforum [mailto:[email protected]] En nombre de ampeck Enviado el: miércoles, 20 de agosto de 2014 05:24 a.m. Para: [email protected] Asunto: Re: Sidewall sprinkler EC QR listed for ordinary hazard II That or 8.3.3.2 Where quick response sprinklers are installed, ALL sprinkler within a compartment shall be quick response. I doubt its for QR reduction if its a pocket ceiling? Dont know what kind of pockets but probably have unprotected pockets greater the 32 sq ft. Im just guessing. I have no idea about a EC QR OHII HSW, the closest thing I can find is TYCO EC-HS-8.0 and it says installation per VdS CEA 4001, Annex E, LH/OHI. Nothing about OHII.
