It's done all the time. Do the hydro test then knock out the links. Ron F -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Wednesday, March 05, 2014 7:25 AM To: [email protected] Subject: Modifying sprinklers
Received a shop drawing stating that for the deluge system, the contractor would purchase standard fused sprinklers and remove the fusible link. Now I can't find specific NFPA verbiage that would prohibit this but seems to me that a sprinkler that is listed for LH or OH occupancies would not be acceptable for an EH deluge system just by popping the link out. Wouldn't this also be modifying the sprinkler post production? Maybe this is done all the time, but what say ye? I found this statement in 13, "8.4.4 Open Sprinklers. 8.4.4.1 Open sprinklers shall be permitted to be used in deluge systems to protect special hazards or exposures or in other special locations." Seems kind of like a DUH, statement. What other type of sprinkler would you use for deluge other than open? Craig L.
