Am I missing something? 80+ story High Rise without sprinkler protection? ---------------------------------------- From: "Versoi, Michael" <michael.ver...@siemens.com> Sent: Tuesday, August 02, 2016 8:59 AM To: "sprinklerforum@lists.firesprinkler.org" <sprinklerforum@lists.firesprinkler.org> Subject: High Rise Class II testing
A colleague has posed a question regarding proper testing of waterflow devices in a 80+ story High Rise in Chicago. At a certain point in the building, the systems installed reduce to a Class II standpipe only. The waterflow devices in the building have, in the past, been tested with several hundred feet of garden hose to slop sinks. This has worked. The question has been raised whether, due to the lack of sprinklers, and the presence of hand hoses, shouldn't the waterflow be induced at the 1-1/2" hand hose connection, possibly into a testing tank. They haven't found any code reference regarding preference to testing orifice size for this circumstance, and, I believe, if the device is being successfully tested with an orifice not less than ½" this is acceptable. Any thoughts or comments? Best regards, Michael Versoi Fire Sprinkler General Foreman NICET III Siemens Industry, Inc.
