Care and
Maintenance
The TYCO ILLUSION, 11.2 K-factor,
Extra Large Orifice Concealed Pendent
Sprinklers must be maintained and
serviced in accordance with this
section.
Absence of the Cover Plate Assembly
may delay sprinkler operation in a fire
situation.
When properly installed, there is a
nominal 3/32 in. (2,4 mm) air gap
between the lip of the Cover Plate
and the ceiling, as shown in Figure 2.
This air gap is necessary for proper
operation of the sprinkler by allowing
heat flow from a fire to pass below and
above the Cover Plate to help assure
appropriate release of the Cover Plate
in a fire situation. If the ceiling is to be
repainted after the installation of the
Sprinkler, care must be exercised to
ensure that the new paint does not seal
off any of the air gap.
Factory painted Cover Plates must not
be repainted. They should be replaced,
if necessary, by factory painted
units. Non-factory applied paint may
adversely delay or prevent sprinkler
operation in the event of a fire.
Do not pull the Cover Plate relative to
the Enclosure. Separation may result.
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.
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.
Modified 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. Also, replace any sprin-
kler that has a cracked bulb or that has
lost liquid from its bulb. (Ref. Installa-
tion Section).
If a sprinkler must be removed, do not
reinstall it or a replacement without
reinstalling the Cover Plate Assembly.
If a Cover Plate Assembly becomes
dislodged during service, replace it
immediately.
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.
Automatic sprinkler systems should be
inspected, tested, and maintained by a
qualified Inspection Service in accor-
dance with local requirements and/or
national codes.
