Automatic sprinkler RFII-C-5.6 K-factor

The TYCO Series RFII-C, 5.6 K-factor Special Application Royal Flush II Quick Response Concealed Pendent Sprinklers for Corridors and Hallways of Light Hazard Occupancies are decorative, 3 mm bulb-type sprinklers featuring a flat cover plate designed to conceal the sprinkler. These sprinklers are specifically designed for use in long, narrow spaces such as corridors or hallways with a maximum coverage area of 28 ft by 10 ft (8,5 m x 3,1 m). Fewer sprinklers and lower system pressure demands are required as compared to the traditional extended coverage sprinklers. The Series RFII-C sprinklers are intended for use in automatic sprinkler systems designed in accordance with standard installation rules such as NFPA 13. The fast-response thermal sensitivity rating of the Series RFII-C sprinkler provides for a Quick Response, Extended Coverage (QREC) rating up to a 28 ft x 10 ft (8,5 m x 3,1 m) maximum coverage area. Each sprinkler includes a cover plate/retainer assembly and a sprinkler/support cup assembly. The separable, two-piece assembly design provides the following benefits: • Allows installation of the sprinklers and pressure testing of the fire protection system prior to installation of a suspended ceiling or application of the finish coating to a fixed ceiling. • Permits the removal of suspended ceiling panels for access to building service equipment without having to first shut down the fire protection system and remove sprinklers. • Provides for 1/2 in. (12,7 mm) of vertical adjustment to allow a measure of flexibility in determining the length of fixed piping to cut for the sprinkler drops.
