01 TYCO White Conc Pend QRSeries RFII — 5.6 K-factor “Royal Flush II” Concealed Pendent Sprinklers Quick & Standard Response, Standard Coverage Page 1 of 4 APRIL 2016 TFP181 IMPORTANT Always refer to Technical Data Sheet TFP700 for the “INSTALLER WARNING” that provides cautions with respect to handling and instal- lation of sprinkler systems and com- ponents. Improper handling and installation can permanently damage a sprinkler system or its compo- nents and cause the sprinkler to fail to operate in a fire situation or cause it to operate prematurely. Worldwide Contacts www.tyco-fire.com General Description The TYCO Series RFII 5.6 K-factor, “Royal Flush II” Concealed Pendent Sprinklers Quick Response (3-mm bulb) and Standard Response (5-mm bulb), are decorative sprinklers fea- turing a flat cover plate designed to conceal the sprinkler. These sprinklers are optimal for architecturally sensi- tive areas such as hotel lobbies, office buildings, churches, and restaurants. Each sprinkler includes a Cover Plate/ Retainer Assembly and a Sprinkler/ Support Cup Assembly. The separa- ble, two-piece assembly design pro- vides the following benefits: • Allows installation of the sprinklers and pressure testing of the fire pro- tection 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 inch (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. The Series RFII Sprinklers are shipped with a Disposable Protective Cap. The Protective Cap is temporarily removed during installation and replaced to help protect the sprinkler during ceiling installation or finish. The tip of the Pro- tective Cap can be used to mark the center of the ceiling hole into plaster board or ceiling tiles by gently pushing the ceiling product against the Pro- tective Cap. When ceiling installa- tion is complete, the Protective Cap is removed and the Cover Plate/Retainer Assembly is installed. As an option, the Series RFII Standard Response (5-mm bulb) “Royal Flush II” Concealed Pendent Sprinklers can be fitted with a silicone Air and Dust Seal. (Refer to Figure 5.) The Air and Dust Seal is intended for sensitive areas where it is desirable to prevent air and dust from the area above the ceiling to pass through the cover plate. NOTICE The Series RFII Concealed Pendent Sprinklers described herein must be installed and maintained in compliance with this document and with the appli- cable standards of the National Fire Protection Association, in addition to the standards of any authorities having jurisdiction. Failure to do so may impair the performance of these devices. The owner is responsible for maintain- ing their fire protection system and devices in proper operating condition. The installing contractor or sprinkler manufacturer should be contacted with any questions.

Stainless Steel Design Criteria The TYCO Series RFII 5.6 K-factor, “Royal Flush II” Concealed Pendent Sprinklers are intended for fire protec- tion systems designed in accordance with the standard installation rules recognized by the applicable Listing or Approval agency; for example, UL Listing is based on NFPA 13 and VdS Approval is based on the CEA 4001. For more information on LPCB and VdS Approvals, contact Tyco Fire Protection Products at the following office: Enschede, Netherlands Telephone: 31-53-428-4444 Fax: 31-53-428-3377 The Series RFII Concealed Pendent Sprinklers are only listed and approved with the Series RFII Concealed Cover Plates having a factory applied finish. NOTICE Do not use the Series RFII in applica- tions where the air pressure above the ceiling is greater than that below. Down drafts through the Sprinkler/Support Cup Assembly can delay sprinkler operation in a fire situation. Operation When exposed to heat from a fire, the Cover Plate, normally soldered to the Retainer at three points, falls away to expose the Sprinkler/Support Cup Assembly. The Deflector — supported by the Guide Pins — then drops down to its operational position. The glass bulb contains a fluid that expands when exposed to heat. When the rated temperature is reached, the fluid expands sufficiently to shatter the glass bulb, activating the sprinkler and allowing water to flow. Installation The TYCO Series RFII 5.6 K-factor, “Royal Flush II” Concealed Pendent Sprinklers must be installed in accor- dance with this section. General Instructions Do not install any bulb-type sprinkler if the bulb is cracked or there is a loss of liquid from the bulb. With the sprin- kler held horizontally, a small air bubble should be present. The diameter of the air bubble is approximately 1/16 inch (1,6 mm) for the 155°F (68°C) and 3/32 inch (2,4 mm) for the 200°F (93°C) tem- perature ratings. A leak-tight 1/2 inch NPT sprinkler joint should be obtained by applying a minimum to maximum torque of 7 to 14 ft.-lbs. (9,5 to 19,0 Nm). Higher levels of torque can distort the sprinkler Inlet with consequent leakage or impairment of the sprinkler. Do not attempt to compensate for insufficient adjustment in the Sprinkler by under- or over-tightening the Sprin- kler/Support Cup Assembly. Re-adjust the position of the sprinkler fitting to suit. Step 1. Install the sprinkler only in the pendent position with the center-line of the sprinkler perpendicular to the mounting surface. Step 2. Remove the Protective Cap. Step 3. With pipe thread sealant applied to the pipe threads, hand- tighten the sprinkler into the sprinkler fitting. Step 4. Wrench-tighten the sprinkler using only the RFII Sprinkler Wrench. (Refer to Figure 3.) Apply the RFII Sprinkler Wrench to the Sprinkler as shown in Figure 3.

Replace the Protective Cap by pushing it upwards until it bottoms out against the Support Cup. (Refer to Figure 4.) The Protective Cap helps prevent damage to the Deflector and Arms during ceiling installation and/or finish. You can also use the Protective Cap to locate the center of the clear- ance hole by gently pushing the ceiling material up against the center point of the Protective Cap. NOTICE As long as the Protective Cap remains in place, the system is considered “Out of Service”. Step 6. After the ceiling has been completed with the 2-1/2 inch (63,5 mm) diameter clearance hole and in preparation for installing the Cover Plate/Retainer Assembly, remove and discard the Protective Cap. Verify that the Deflector moves up and down freely. If the Sprinkler is damaged and the Deflector does not move up and down freely, replace the entire Sprinkler. Do not attempt to modify or repair a damaged sprinkler. Step 7. When installing an Air and Dust Seal, refer to Figure 5; otherwise, proceed to Step 8. To attach the Air and Dust Seal, verify the angle of the outside edge of the seal is oriented according to Figure 5. Start the edge of the Retainer in the grooved slot of the Air and Dust Seal and continue around the retainer until the entire Air and Dust Seal is engaged.

All rights reserved. TEFLON is trademark of The DuPont Corporation Step 8. Screw on the Cover Plate/ Retainer Assembly until the Retainer (shown in Figure 2) or the Air and Dust Seal (shown in Figure 5) contacts the ceiling. Do not continue to screw on the Cover Plate/Retainer Assembly so that it lifts a ceiling panel out of its normal position. If you cannot engage the Cover Plate/Retainer Assembly with the Support Cup or you cannot engage the Cover Plate/Retainer Assembly suf- ficiently to contact the ceiling, you must reposition the Sprinkler Fitting. Care and Maintenance The TYCO Series RFII 5.6 K-factor, “Royal Flush II” Concealed Pendent Sprinklers must be maintained and serviced in accordance with this section. Before closing a fire protection system main control valve for maintenance work on the fire protection system that it controls, obtain permission to shut down the affected fire protection system from the proper authorities and notify all personnel who may be affected by this action. Absence of the Cover Plate/Retainer Assembly can delay sprinkler opera- tion in a fire situation. When properly installed, there is a nominal 3/32 inch (2,4 mm) air gap between the lip of the Cover Plate and the ceiling, as shown in Figure 2. This air gap is necessary for proper operation of the sprinkler. If the ceiling requires repainting after sprinkler installation, ensure that the new paint does not seal off any of the air gap. Do not pull the Cover Plate relative to the Enclosure. Separation may result. Sprinklers which are found to be leaking or exhibiting visible signs of corrosion must be replaced. Automatic sprinklers must never be painted, plated, coated, or other- wise altered after leaving the factory. Modified sprinklers must be replaced. Sprinklers that have been exposed to corrosive products of combustion, but have not operated, should be replaced if they cannot be completely cleaned by wiping the sprinkler with a cloth or by brushing it with a soft bristle brush. Care must be exercised to avoid damage to the sprinklers - before, during, and after installation. Sprin- klers damaged by dropping, striking, wrench twist/slippage, or the like, must be replaced. Also, replace any sprin- kler that has a cracked bulb or that has lost liquid from its bulb. (Ref. Installa- tion Section.) Exercise care to avoid damage to sprin- klers before, during, and after instal- lation. Replace sprinklers damaged by dropping, striking, wrench twist- ing, wrench slipping, or the like. Also, replace any sprinkler that has a cracked bulb or that has lost liquid from its bulb. (Refer to the Installation section.) If you must remove a sprinkler, do not reinstall it or a replacement without reinstalling the Cover Plate/Retainer Assembly. If a Cover Plate/Retainer Assembly becomes dislodged during service, replace it immediately. The owner is responsible for the inspection, testing, and maintenance of their fire protection system and devices in compliance with this document, as well as with the applicable standards of the National Fire Protection Asso- ciation (e.g., NFPA 25), in addition to the standards of any other authorities having jurisdiction. Contact the install- ing contractor or sprinkler manufac- turer regarding any questions. Automatic sprinkler systems should be inspected, tested, and maintained by a qualified Inspection Service in accor- dance with local requirements and/or national code.
