Care and
Maintenance
The TYCO Series TY-FRL 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, permission to shut down 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.
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 or over-heated sprinklers must be
replaced.
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.
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 product manufacturer
with any questions.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with local
requirements and/or national codes.
