Page 2 of 2 <br /> LAlternative Means and Methods (cont.): <br /> As an alternative to the installation of in-rack sprinklers,we are proposing to install a TYCO Fire Products <br /> QuellTM system. As shown in the attached fire tests the TYCO Fire Products QuellTM system provides an <br /> equivalent level of fire control with ceiling sprinklers only, as compared to designs provided in NFPA 13 <br /> that incorporate a ceiling and in-rack design. The TYCO Fire Products QuellTM system has been specifically <br /> designed and tested for high rack freezer installations such as that associated with this project. The TYCO <br /> Fire Products QuellTM system will be designed and installed in accordance with its manufacturer's design <br /> criteria and will include the following: <br /> a. Water Demand-Twenty-five (25) Quell TM sprinklers designed to discharge at 30 PST including <br /> 300 GPM outside hose allowance. <br /> b. Fluid Delivery--It is required that water be delivered to the four (4) most remote sprinklers in no <br /> greater than 25 seconds, and that the software verifying this duration be specifically listed. <br /> c. The fire pump will be prestarted upon detection to facilitate fluid delivery. <br /> d. Mechanical fans•will be shut down upon detection to prevent excessive air movement at the ceiling. <br /> Please review the attached data sheets and associated testing data. Should you have any questions or require <br /> additional documentation please contact us. <br /> Thank you for reviewing this documentation and considering our request. <br /> Respectfully submitted, <br /> Ahern Fite Protection <br /> A division of].
