<br />Series TY-FRS - 2.8, 4.2, 5.6, and 8.0 K-factor
<br />Upright, Pendent, and Recessed Pendent Sprinklers
<br />Quick Response, Standard Coverage
<br />
<br />General
<br />Description
<br />
<br />The Series TV-FRS, 2,8, 4.2, 5.6, and
<br />8.0 K-factor, Upright and Pendent
<br />Sprinklers described in this data sheet
<br />are quick response - standard cover-
<br />age, decorative 3 mm glass bulb type
<br />spray sprinklers designed for use in
<br />light or ordinary hazard, commercial
<br />occupancies such as banks, hotels,
<br />shopping malls, etc.
<br />
<br />The recessed version of the Series
<br />TV-FRS Pendent Sprinkler, where ap-
<br />plicable, is intended for use in areas
<br />with a finished ceiling. It uses either a
<br />two-piece Style 10 (1/2 inch NPT) or
<br />Style 40 (3/4 inch NPT) Recessed Es-
<br />cutcheon with 1/2 inch (12,7 mm) of
<br />recessed adjustment or up to 3/4 inch
<br />(19,1 mm) of total adjustment from the
<br />flush pendent position, or a two-piece
<br />Style 20 (1/2 inch NPT) or Style 30 (3/4
<br />inch NPT) Recessed Escutcheon with
<br />1/4 inch (6,4 mm) of recessed adjust-
<br />ment or up to 1/2 inch (12,7 mm) of
<br />total adjustment from the flush pen-
<br />dent position. The adjustment provided
<br />by the Recessed Escutcheon reduces
<br />the accuracy to which the fixed pipe
<br />drops to the sprinklers must be cut.
<br />
<br />Corrosion resistant coatings, where
<br />applicable. are utilized to extend the
<br />life of copper alloy sprinklers beyond
<br />that which would otherwise be ob-
<br />tained when exposed to corrosive at-
<br />
<br />IMPORTANT
<br />Always refer to Technical Data
<br />Sheet TFP700 for the "INSTALLER
<br />WARNINGn that provides cautions
<br />with respect to handling and instal-
<br />lation of sprinkler systems and com-
<br />ponents. Improper handling and in-
<br />stallation can permanently damage
<br />a sprinkler system or its compo-
<br />nents and cause the sprinkler to fail
<br />to operate in a fire situation or cause
<br />it to operate prematurely.

<br />mospheres. Although corrosion resis-
<br />tant coated sprinklers have passed the
<br />standard corrosion tests of the appli-
<br />cable approval agencies, the testing is
<br />not representative of all possible cor-
<br />rosive atmospheres. Consequently, it
<br />is recommended that the end user be
<br />consulted with respect to the suitability
<br />of these coatings for any given corro-
<br />sive environment. The effects of ambi-
<br />ent temperature, concentration of
<br />chemicals, and gas/chemical velocity,
<br />should be considered, as a minimum,
<br />along with the corrosive nature of the
<br />chemical to which the sprinklers will be
<br />exposed.

<br />An intermediate level versions of the
<br />Series TV-FRS Pendent Sprinklers are
<br />detailed in Technical Data Sheet
<br />TFP356, and Sprinkler Guards are de-
<br />tailed in Technical Data Sheet TFP780
<br />
<br />WARNINGS
<br />The Series TY-FRB Sprinklers de-
<br />scribed herein must be installed and
<br />maintained in compliance with this
<br />document, as well as with the applica-
<br />ble standards of the National Fire Pro-
<br />tection Association, in addition to the
<br />standards of any other authorities hav-
<br />ing jurisdiction. Failure to do so may
<br />Impair the performance of these de-
<br />vices,
<br />
<br />The owner is responsible for maintain-
<br />ing their fire protection system and de-
<br />vices in proper operating condition.
<br />The installing contractor or sprinkler
<br />manufacturer should be contacted
<br />with any questions.
