However, the use of the Figure 730Tee for this arrangement is limited towet pipe systems.The configuration shown in Figure 8 isonly applicable for wet pipe systemswhere the sprinkler fitting and waterfilled pipe above the sprinkler fitting arenot subject to freezing and where thelength of the Dry-Type Sprinkler has theminimum exposure length depicted inFigure 9. Refer to the Exposure Lengthsection. 1 in. x 1 in. NPT Female Adapter(P/N 80145) 1 in. x 1 in. x 1 in. NPT SprinklerHead Adapter Tee (P/N 80249)For dry pipe system installations,use only the side outlet of maximum2-1/2 inch reducing tee when locating Series DS-2 Dry-Type Sprinklersdirectly below the branch line. Otherwise, use the configuration shownin Figure 9 to assure complete waterdrainage from above Series DS-2 DryType Sprinklers and the branchline.Failure to do so may result in pipefreezing and water damage.NOTICEDo not install Series DS-2 Dry-TypeSprinklers into any other type fittingwithout first consulting the TechnicalServices Department. Failure to use theappropriate fitting may result in one ofthe following: failure of the sprinkler to operateproperly due to formation of iceover the Inlet Plug or binding of theInlet Plug insufficient engagement of theInlet pipe-threads with consequentleakageDrainageIn accordance with the minimumrequirements of the NATIONAL FIREPROTECTION ASSOCIATION for drypipe sprinkler systems, branch, cross,and feed-main piping connected to DrySprinklers and subject to freezing temperatures must be pitched for properdrainage.Exposure LengthWhen using dry sprinklers in wet pipesprinkler systems to protect areassubject to freezing temperatures, useTable C to determine a sprinkler’sappropriate exposed barrel length toprevent water from freezing in the connecting pipes due to conduction. Theexposed barrel length measurementmust be taken from the face of thesprinkler fitting to the surface of thestructure or insulation that is exposedto the heated area. Refer to Figure 9 foran example.For protected area temperaturesbetween those given above, theminimum recommended length fromthe face of the fitting to the outside ofthe protected area may be determinedby interpolating between the indicatedvalues.

TFP540Page 7 of 8Clearance SpaceIn accordance with NFPA 13, whenconnecting an area subject to freezing and an area containing a wet pipesprinkler system, the clearance spacearound the sprinkler barrel of Dry-TypeSprinklers must be sealed. Due totemperature differences between twoareas, the potential for the formation ofcondensation in the sprinkler and subsequent ice build-up is increased. Ifthis condensation is not controlled, icebuild-up can occur that might damagethe dry-type sprinkler and/or preventproper operation in a fire situation.Step 1. With a non-hardening pipethread sealant such as TEFLON appliedto the Inlet threads, hand-tighten thesprinkler into the sprinkler fitting. Donot grasp the sprinkler by the deflector(Ref. Figure 7).Use of the Model DSB-2 Dry Sprinkler Boot, described in Technical DataSheet TFP591 and shown in Figure 11,can provide the recommended seal.Note: If sprinkler removal becomesnecessary, remove the sprinkler usingthe same wrenching method notedabove. Sprinkler removal is easier whena non-hardening sealant was usedand torque guidelines were followed.After removal, inspect the sprinkler fordamage.InstallationTYCO Series DS-2 Dry-Type Sprinklers, 11.2K Pendent, Extended Coverage, Light and Ordinary Hazard mustbe installed in accordance with thissection.General InstructionsSeries DS-2 Dry-Type Sprinklers mustonly be installed in fittings that meetthe requirements of the Design Criteria section. Refer to the Design Criteriasection for other important requirements regarding piping design andsealing of the clearance space aroundthe Sprinkler Casing. With referenceto Figure 7, do not grasp the sprinklerby the deflector. Failure to follow thisinstruction may impair performance ofthe device.Do not install any bulb-type sprinklerif the bulb is cracked or there is a lossof liquid from the bulb. With the sprinkler held horizontally, a small air bubbleshould be present. The diameter of theair bubble is approximately 1/16 inch(1,6 mm) for the 135 F (57 C) rating to1/8 inch (3,2 mm) for the 360 F (182 C)rating.A leak-tight 1 inch NPT sprinkler jointshould be obtained by applying a minimum-to-maximum torque of 20 to30 lb-ft (26,8 to 40,2 N·m). Higher levelsof torque may distort the sprinkler Inletwith consequent leakage or impairmentof the sprinkler.Do not attempt to compensate forinsufficient adjustment in an Escutcheon Plate by under or over-tighteningthe Sprinkler. Re-adjust the position ofthe sprinkler fitting to suit.Note: Install pendent sprinklers only inthe pendent position. The deflector ofa pendent sprinkler must be parallel tothe ceiling.Step 2. Wrench-tighten the sprinklerusing either: a pipe wrench on the Inlet Band orthe Casing (Ref. Figure 1) a W-Type 17 Sprinkler Wrench onthe wrench flat (Ref. Figure 6); applythe wrench recess of the W-Type 17Sprinkler Wrench to the wrench flatStep 3. After installing the ceiling andapplying a ceiling finish, slide on theouter piece of the Escutcheon untilit comes in contact with the ceiling.Do not lift the ceiling panel out of itsnormal position.When using the Deep Escutcheon,hold the outer piece in contact with themounting surface (ceiling or wall). Thenrotate the inner piece approximately 1/4turn with respect to the outer piece,to hold the Deep Escutcheon firmlytogether.Care andMaintenanceTYCO Series DS-2 Dry-Type Sprinklers,11.2K Pendent, Extended Coverage,Light and Ordinary Hazard must bemaintained and serviced in accordancewith this section.Before closing a fire protection systemmain control valve for maintenancework on the fire protection systemthat it controls, obtain permission toshut down the affected fire protectionsystems from the proper authoritiesand notify all personnel who may beaffected by this action.Absence of the outer piece of anescutcheon, which is used to cover aclearance hole, may delay the time tosprinkler operation in a fire situation.A Vent Hole is provided in the BulbSeat (Ref. Figure 1) to indicate if the DrySprinkler is remaining dry. Evidence ofleakage from the Vent Hole indicatespotential leakage past the Inlet sealand the need to remove the sprinklerto determine the cause of leakage, e.g.,an improper installation or an ice plug.Close the fire protection system controlvalve and drain the system beforeremoving the sprinkler.Sprinklers which are found to beleaking or exhibiting visible signs ofcorrosion must be replaced.Automatic sprinklers must never bepainted, plated, coated, or otherwise altered after leaving the factory.Modified sprinklers must be replaced.Sprinklers that have been exposed tocorrosive products of combustion, buthave not operated, should be replacedif they cannot be completely cleanedby wiping the sprinkler with a cloth orby brushing it with a soft bristle brush.Care must be exercised to avoiddamage to the sprinklers before,during, and after installation. Sprinklers damaged by dropping, striking,wrench twist/slippage, or the like, mustbe replaced. Also, replace any sprinklerthat has a cracked bulb or that has lostliquid from its bulb. (Refer to Installation Section.)The owner is responsible for the inspection, testing, and maintenance of theirfire protection system and devices incompliance with this document, as wellas with the applicable standards of theNATIONAL FIRE PROTECTION ASSOCIATION (e.g., NFPA 25), in addition tothe standards of any other authoritieshaving jurisdiction. Contact the installing contractor or product manufacturerwith any questions.Automatic sprinkler systems are recommended to be inspected, tested,and maintained by a qualified Inspection Service in accordance with localrequirements and/or national codes.
