More specifically, it is our intent to demonstrate that the rated diffusers, while tested for use in rated `°T-bar" or "lay-in" acoustical tile ceiling assemblies,.are capable of achieving an equivalent rating and performance when installed in a rated drywall ceiling assembly. Attached please find the following documents for your reference and review: 1. Rolf Jensen & Associates' review letter (dated 9/15/09) summarizing their review of the manufacturer's (E.H. Price) information and HKS' proposed installation details. This letter summarizes RJA's findings that the proposed assembly achieves equivalent rating and performance. 2. E.H. Price's letter (dated 8/24/09) describing their instructions for alternate installation in rated drywall ceiling assemblies for the purpose of achieving equivalent rating. This letter also states that this alternate installation has been previously proposed for use in other projects (in other jurisdictions) and was approved by the local authorities. REVIEWED BY 3. E.H.

Price Limited of Winnipeg Canada, at the ceiling of the 2-hour exit passageways at the Vail Four Seasons project for compliance with the 2003 International Building Code (IBC) as adopted by the Town of Vail and with our Life Safety Report, dated May 22, 2007. The TBD2-FR product is listed as a 3-hour fire-resistance rated linear diffuser with an integrated fire damper for installation within T-bar ceilings, also known as lay-in, acoustic tile or suspended ceilings. The diffuser is designed to clip into a grid system, thereby providing the required stability to keep the diffuser in place. When transitioning to another mode of installation and different ceiling material, we believe the method of connection would be the chief concern as this product has not been tested for installation at a hard lid ceiling. We have reviewed a letter provided by E.H. Price dated August 24, 2009 concerning the proposed installation as well as the technical data sheet for this product and agree with the manufacturer regarding alternate installation methodology within a gypsum board surface. We have also reviewed the detail provided by HKS Hill Glazier Studio, dated April 7, 2009 and revised September 11, 2009 for the specific installation of this product within a 2-hr shaftwall ceiling assembly and find that the proposed installation meets the intent of the code. The steel plaster frame provided by the manufacturer will need to be field verged for vertical stability. The framing of the 2-hr shaftwall, combined with the attached ductwork will provide adequate lateral stability. REv1EJVED B ~ 1 0 4 „y . LJ. MEMO i6O 02009 RoN JwiW & Anodalft Mo.

Fax: 204.661.7784 RE: Price Fire Rated Linear Diffuser To Whom It May Concern, This letter will suggest an alternative method for mounting or installing a Price TBD2-FR series linear diffuser in a ceiling surface mount for drywall or gypsum board construction. Currently most major air distribution manufacturers only offer fire rated grilles, registers and diffusers for an exposed grid suspended ceiling with up to a three-hour fire rating. Each fire rated product must be designed to meet the time versus temperature test criteria of the National Fire Protection Association (NFPA) Standard 90A. There are applications where fire rated products are required to be surface mounted into a drywall/gypsum board ceiling. Price's FR (fire rated) series grilles, registers and diffusers have the potential to be used in this type of application, but will not be certified by UL/ULC. It is up to the discretion of the local building inspector/authority to approve and re-certify this type of installation as the recommendations made by Price have not been tested or approved by any other certification program. The intended purpose for the alternative surface mount installation is to achieve an equivalent rating. Alternatives for installation of fire rated diffusers in gypsum board surface mount applications are as follows: a steel mounting frame designed to allow the TBD2-FR to lay into its inner frame and larger footprint fire blanket would be required. The steel mounting frame would be installed into the ceiling opening and secured into place. Next the TBD2-FR diffuser would lay into the steel mounting frame and the fire blanket would provide coverage around the perimeter of the ceiling opening. The fire blanket should extend from the edge of the diffuser and past the mounting frame onto the ceiling by approximately 6.0". The purpose for the larger fire blanket is to provide additional fire suppression in case there is a space or gap between the drywall/gypsum board ceiling and steel mounting frame, preventing the flame from spread into the ceiling plenum area. The above alternative installation method have been proposed on previous jobs with similar requirements. It has been Prices' understanding that this type of installation was approved by the local building authority before securing the order of our E.H Price sales office. It is strongly recommended that the local building authority approve this installation method before placing any product order. If you have any further questions, please contact your local E. H. Price Representative.

"All the ducts feeding the fire-rated diffusers located in the fife-rated shaftwall ceiling; when they enter the passageway shell and penetrate the vertical walls of the passageway, they are protected by the combination fire smoke dampers. If there is smoke corning through the ducts from other areas than the passageway, then the smoke will be stopped by the fire smoke dampers, where the ducts.are penetrating the vertical wall of -the passageway.. This works also the other way too; if there is smoke in the passageway, it will be stopped also at the fire smoke damper locations, where the ducts are. penetrating the passageway vertical wall., and the smoke will not migrate into other areas- I think that the combination of fire rated diffusers with fire smoke dampers on the vertical wall, together with the fire rated shaft-wall ceiling, do provide the adequate fire and smoke protection of the passageway, not a lesser protection " Both HKS Architects and Rolf Jensen & Associates, our fire protection consultants, have reviewed Mr Duta's letter and agree that the use of the fire rated diffusers in combination with the smoke/fire dampers at the vertical wall, will provide the necessary protection for these 2-hour rated exit passageways and respectfully submit this letter, with our signatures, for your review and acceptance.

All the ducts feeding the fire-rated diffusers located in the fire-rated shaftwall ceiling, when they enter, the passageway shell and penetrate the vertical walls of the passageway, they are protected by the.combination fire smoke dampers. If there is smoke coming through the ducts from other areas than the passageway, then the smoke will be stopped by the fire smoke dampers, where the ducts are penetrating the vertical wall of the passageway. This works also the other way too: if there is smoke in the passageway, it will be stopped also at the fire smoke damper locations, where the ducts are penetrating the passageway vertical wall, and the smoke will not migrate into other areas. I think that the combination of fire rated diffusers with fire smoke dampers on the vertical wall, together with the fire rated shaftwall ceiling, do provide the adequate fire and smoke protection of the passageway, not a lesser protection.

There are no penetrations or openings that do not serve the passageway, as required by IBC 1020.4 and 1020.5. The design was such that there is to be a separate wall framed on the unit side of the passageways to house the plumbing and electrical to serve the units. The contractors did not frame the non- rated wall, the plumbing and electrical is installed within the 2 passageway walls. There is also piping, ducting and electrical systems installed within the exit passageway above the non-rated ceiling that is not allowed. 1 The re-submittal needs to be presented as a performance based solution to the prescriptive the code. The submittal is to be sealed and signed by the Fire Protection Engineer of record requirements •e use the International Performance Code Chapter One for reference regarding submittal documents. 2 This submittal did not address the plumbing that is installed In the 2 hour walls. Please provide a mefhoa of maintaining the 2 hour integrity of the wall and isolate these pipes from the assembly. These penetrations are not allowed per IBC 1020. 3 Sheet SDA-BUL-09402 indicates to be installed for the ventilation penetrationstopenings of the passageways. These ducts will be required to be protected with - ke damwm. This was addressed during the original review in comment #216. Once given a level of protection, that protection shall not be reduced.
