Worldwide www.tyco-fire.com Contacts Model TN-17 16.8 (K240) K-factor Horizontal Spray Nozzle, Open General Description The TYCO Model TN-17 Horizontal Spray Nozzle having a 16.8 (K240) K-factor is a specialized open nozzle for use in tunnel fire protection deluge systems, providing an improved alternative to traditional designs. With its ability to provide extended coverage, the Model TN-17 Nozzle allows for a single pipe to run the length of a tunnel, compared to traditional designs that use multiple pipes in order to provide sufficient coverage. The Model TN-17 Nozzle is an open nozzle designed to be integrated into a deluge fire protection system. The Model TN-17 Nozzle provides protection of coverage areas up to 16 ft 4 in. x 32 ft 8 in. (5,0 m x 10,0 m) as compared to standard coverage sprinklers often used in tunnel fire protection system designs having a maximum coverage area of 10 ft x 10 ft (3,0 m x 3,0 m). NOTICE The TYCO Model TN-17 Horizontal Spray Nozzle described herein must be installed and maintained in compliance with this document and with the applicable standards recognized by any authorities having jurisdiction. Failure to do so may impair the performance of these devices. The design of individual fixed water spray systems for fire protection can vary considerably, depending on the characteristics and nature of the hazard, the basic purpose of the spraying system, the configuration of the hazard, and wind/draft/ventilation conditions. Because of these variations, the design of fixed water spray systems must only be performed by experienced designers who thoroughly understand the limitations as well as capabilities of such systems. The Tunnel Operator is responsible for maintaining their fire protection system and devices in proper operating condition. Contact the installing contractor or product manufacturer with any questions.
