Care and
<br />Maintenance
<br />The TYCO Series TY-FRB, 5.6 K-factor,
<br />Upright (TY313) and Pendent (TY323)
<br />Sprinklers must be maintained and ser-
<br />viced in accordance with this section.
<br />Before closing a fire protection system
<br />main control valve for maintenance
<br />work on the fire protection system
<br />that it controls, obtain permission to
<br />shut down the affected fire protection
<br />systems from the proper authorities
<br />and notify all personnel who may be
<br />affected by this action.
<br />Absence of the outer piece of an
<br />escutcheon, which is used to cover
<br />a clearance hole, can delay sprinkler
<br />operation in a fire situation.
<br />The owner must assure that the sprin-
<br />klers are not used for hanging any
<br />objects and that the sprinklers are only
<br />cleaned by means of gently dusting
<br />with a feather duster; otherwise, non -
<br />operation in the event of a fire or inad-
<br />vertent operation may result.
<br />Sprinklers which are found to be
<br />leaking or exhibiting visible signs of
<br />corrosion must be replaced.
<br />Automatic sprinklers must never be
<br />painted, plated, coated, or other-
<br />wise altered after leaving the factory.
<br />Modified sprinklers must be replaced.
<br />Sprinklers that have been exposed to
<br />corrosive products of combustion, but
<br />have not operated, should be replaced
<br />if they cannot be completely cleaned
<br />by wiping the sprinkler with a cloth or
<br />by brushing it with a soft bristle brush.
<br />Care must be exercised to avoid
<br />damage to the sprinklers before,
<br />during, and after installation. Sprin-
<br />klers damaged by dropping, striking,
<br />wrench twist/slippage, or the like, must
<br />be replaced. Also, replace any sprin-
<br />kler that has a cracked bulb or that has
<br />lost liquid from its bulb. (Ref. Installa-
<br />tion Section.)
<br />The owner is responsible for the
<br />inspection, testing, and maintenance of
<br />their fire protection system and devices
<br />in compliance with this document, as
<br />well as with the applicable standards
<br />of the National Fire Protection Asso-
<br />ciation (e.g., NFPA 25), in addition to
<br />the standards of any other authorities
<br />having jurisdiction. Contact the install-
<br />ing contractor or product manufacturer
<br />with any questions.
<br />Automatic sprinkler systems are rec-
<br />ommended to be inspected, tested,
<br />and maintained by a qualified Inspec-
<br />tion Service in accordance with local
<br />requirements and/or national codes.
