Ron, We talked about this in the Hanging and Bracing committee. We came up with the following new section in NFPA-13,
9.2.1.3.3.4* Where flexible sprinkler hose fittings are used to connect sprinklers to branch lines in suspended ceilings, a label limiting relocation of the sprinkler shall be provided on the anchoring component. and A.9.2.1.3.3.4 An example of language for the label is as follows: CAUTION: DO NOT REMOVE THIS LABEL. Relocation of this device should only be performed by qualified and/or licensed individuals that are aware of the original system design criteria, hydraulic criteria, sprinkler head listing parameters, and knowledge of the state and local codes including NFPA 13 installation standards. Relocation of the device without this knowledge could adversely affect the performance of this fire protection and life safety system. Norm and his competitors readily agreed to this. -- PARSLEY CONSULTING Ken Wagoner, SET 760.745.6181 voice 760.745.0537 fax [email protected] <mailto:[email protected]> e-mail www.ParsleyConsulting.com <http://www.ParsleyConsulting.com> website Fletcher, Ron wrote: > Even more interesting will be when the electrician, HVAC or ceiling guy > decide they can put the head back close to where it was without a sprinkler > contractor on site. > > Ron Fletcher > Aero Automatic > Phoenix, AZ > > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of Chris Cahill > Sent: Friday, May 28, 2010 7:45 AM > To: [email protected] > Subject: RE: Flexible Heads, a Learnable Moment > > No doubt but I'm sure it's not news you are the Kleenex and Xerox of the > industry.
