It uses either a two-piece Style 10 (1/2 inch NPT) or Style 40 (3/4 inch NPT) Recessed Es- cutcheon with 1/2 inch (12,7 mm) of recessed adjustment or up to 3/4 inch (19,1 mm) of total adjustment from the flush pendent position, or a two-piece Style 20(1/2 inch NPT) or Style 30(3/4 inch NPT) Recessed Escutcheon with 1/4 inch (6,4 mm) of recessed adjust- ment or up to 1/2 inch (12.7 mm) of total adjustment from the flush pen- dent position. The adjustment pro- vided by the Recessed Escutcheon re- duces the accuracy to which the fixed pipe drops to the sprinklers must be cut. Corrosion resistant coatings, where applicable, are utilized to extend the life of copper alloy sprinklers beyond that which would otherwise be ob- IMPORTANT Always refer to Technical Data Sheet TFPTOO for the INSTALLER WARNING that provides cautions with respect to handling and instal- lation of sprinkler systems and com- ponents. Improper handling and in- stallation can permanently damage a sprinkler system or its compo- nents and cause the sprinkler to fall to operate in a fire situation or cause it to operate prematurely, tamed when exposed to corrosive at- mospheres. Although corrosion resis- tant coated sprinklers have passed the standard corrosion tests of the appli- cable approval agencies, the testing is not representative of all possible cor- rosive atmospheres. Consequently, it is recommended that the end user be consulted with respect to the suitability of these coatings for any given corro- sive environment. The effects of ambi- ent temperature, concentration of chemicals, and gas/chemical velocity, should be considered, as a minimum, along with the corrosive nature of the chemical to which the sprinklers will be exposed. An intermediate level versions of the Series TY-FRB Pendent Sprinklers are detailed in Technical Data Sheet TFP356, and Sprinkler Guards are de- tailed in Technical Data Sheet TFP780 WARNINGS The Series TY-FRB Sprinklers de- scribed herein must be installed and maintained in compliance with this document, as well as with the applica- ble standards of the National Fire Pro- tection Association, in addition to the standards of any other authorities hav- ing jurisdiction. Failure to do so may impair the performance of these de- vices. The owner is responsible for maintain- ing their fire protection system and de- vices in proper operating condition. The installing contractor or sprinkler manufacturer should be contacted with any questions.

TABLE C, MAXIMUM WORKING PRESSURE Installation The Series TY-FRB Sprinklers must be installed in accordance with the fol- lowing instructions: NOTES Do not install any bulb type sprinkler if the bulb is cracked or there is loss of liquid from the bulb. With the sprinkler 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 1350F/57°C to 3/32 inch (2,4 mm) for the 286"F/141"C temperature ratings. A leak tight 1/2 inch NPTsprinklerjoint should be obtained with a torque of 7 to 14 ft.lbs. (9,5 to 19,0 Nm). A maxi- mum of 21 ft. lbs. (28,5 Nm) of torque may be used to install sprinklers with 1/2 NPT connections. A leak tight 3/4 inch NPT sprinkler joint should be ob- tained with a torque of 10 to 20 ft.lbs. (13,4 to 26,8 Nm). A maximum of 30 ft.lbs. (40,7 Nm) of torque is to be used to install sprinklers with 3/4 NPT con- nections. Higher levels of torque may distort the sprinkler inlet and cause leakage or impairment of the sprinkler. Do not attempt to make-up for insuffi- cient adjustment in the escutcheon plate by under- or over-tightening the sprinkler. Readjust the position of the sprinkler fitting to suit. The Series TY-FRB Pendent and Up- right Sprinklers must be installed in accordance with the following instruc- tions. Step 1. Pendent sprinklers are to be installed in the pendent position, and upright sprinklers are to be installed in the upright position. Step 2. With pipe thread sealant ap- plied to the pipe threads, hand tighten the sprinkler into the sprinkler fitting. Step 3. Tighten the sprinkler into the sprinkler fitting using only the W-Type 6 Sprinkler Wrench (Ref. Figure 14). With reference to Figures 1, 2, 3, 4, and 5, the W-Type 6 Sprinkler Wrench is to be applied to the sprinkler wrench flats. The Series TY-FRB Recessed Pen- dent Sprinklers must be installed in accordance with the following instruc- tions. Step A. After installing the Style 10. 20, 30, or 40 Mounting Plate, as appli- cable, over the sprinkler threads and with pipe thread sealant applied to the pipe threads, hand tighten the sprin- kler into the sprinkler fitting.

After the ceiling has been in- stalled or the finish coat has been ap- plied, slide on the Style 10, 20, 30, or 40 Closure over the Series TY-FRB Sprinkler and push the Closure over the Mounting Plate until its flange comes in contact with the ceiling. Care and Maintenance The Series TY-FRB Sprinklers must be maintained and serviced in accord- ance with the following instructions: NOTES Before closing a fire protection system main control valve for maintenance work on the fire protection system that it controls, permission to shutdown the affected fire protection system must be obtained from the proper authorities and all personnel who may be affected by this action must be notified. The owner must assure that the sprin- klers are not used for hanging of any objects; otherwie, non-operation in the event of a fire or inadvertent opera- tion may result. Absence of an escutcheon, which is used to cover a clearance hole, may delay the time to sprinkler operation in a fire situation. Sprinklers that are found to be leaking or exhibiting visible signs of corrosion must be replaced. Automatic sprinklers must never be painted, plated, coated or otherwise altered after leaving the factory. Modi- fied 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 dam- age to the sprinklers - before, during, and after installation. Sprinklers dam- aged by dropping, striking, wrench twist/slippage, or the like, must be re- placed. Also, replace any sprinkler that has a craqked bulb or that has lost liquid from its bulb. (Ref. Installation Section). Frequent visual inspections are rec- ommended to be initially performed for corrosion resistant coated sprinklers, after the installation has been corn- 2-7/8" DIA. - (73,0 mm) I 1/2"(12,7 mm) 2-1/4" DIA. 1 I 14"(6,4mm) (57,2 mm) MOUNTING ( , l-IJiIc I (3,2 mm) I I f 1-1/4" (31,8 mm) V (25,4 mm) 1/2±1/8 (12,7±3,2 mm) FACE OF SPRINKLER FITTING I \ - MOUNTING SURFACE CLOSUR SERIES E •, FIGURE 11 SERIES TY-FRB RECESSED PENDENT WITH TWO-PIECE 1/2 INCH TOTAL ADJUSTMENT STYLE 20 RECESSED ESCUTCHEON 5.6 K-FACTOR, 1/2 INCH NPT - 2-78" DIA. 1/2±1/8" (73,0 mm) I 1/2"(12,7 mm) r (12.7±3.2 mm) - 2.1/4" DIA. 1/4" (6,4 mm) I FACE OF (57.2 mm) MOUNTING"] I SPRINKLER PLATE I I FITTING 1/8 (3.2 mm) I MOUNTING SURFACE/ I CLOSURE SERIES 1-5116'(33,3 mm)I TY-FRB 1-1116'(27.0 mm) FIGURE 13 SERIES TY-FRB RECESSED PENDENT WITH TWO-PIECE 1/2 INCH TOTAL ADJUSTMENT STYLE 30-RECESSED ESCUTCHEON 8.0 K-FACTOR, 3/4 INCH NPT TFP171 Page 9 of 10 - 2-7/8" DIA. - 518±1/4" (73.0 mm) I 3/4"(19,1 mm) I I (15.9±6,4 mm) 114" (6,4 mm) I FACE OF MOUNTING SPRINKLER I I - PLATE FITTING (3,21/ B m"m) 16-1 MOUNTING SURFACE/ SERIES 1-1/4" (31,8 mm) CLOSURE TY-FRB 3/4'(19.1 mm) FIGURE 10 SERIES TY-FRB RECESSED PENDENT WITH TWO-PIECE 3/4 INCH TOTAL ADJUSTMENT STYLE 10 RECESSED ESCUTCHEON 5.6 K-FACTOR, 1/2 INCH NPT - 2-7/8DIA. 5/8±1/4" (73,0 mm) .3/4"(19,1 mm) (15,9±6,4 mm) 2-1/4" DIA. 1/4" (6.4 mm) (57.2 mm) FACE OF I I MOUNTING SPRINKLER '"'ç 7"' ,_..- PLATE FITTING I I I Ill I 1/8' (3.2 mm) MOUNTING SURFACE,/ CLOSURE SERIES 1-5/16" (33,3 mm) TVFRB 13/16" (20.6 mm) FIGURE 12 SERIES TY-FRB RECESSED PENDENT WITH 7W0-PIECE 3/4 INCH TOTAL ADJUSTMENT STYLE 40 RECESSED ESCUTCHEON 8.0 K-FACTOR, 3/4 INCH NPT plated, to verify the integrity of the cor- rosion resistant coating. Thereafter, annual inspections per NFPA 25 should suffice; however, instead of in- specting from the floor level, a random sampling of close-up visual inspec- tions should be made, so as to better determine the exact sprinkler condi- tion and the long term integrity of the corrosion resistant coating, as it may be affected by the corrosive conditions present. The owner is responsible for the in- spection, testing, and maintenance of their fire protection system and de- vices in compliance with this docu- ment, as well as with the applicable standards of the National Fire Protec- tion Association (e.g., NFPA 25), in addition to the standards of any other authorities having jurisdiction.
