for installing the Cover Plate Assembly,
remove and discard the Protective Cap,
and verify that the Deflector moves up
and down freely.
If the sprinkler has been damaged and
the Deflector does not move up and
down freely, replace the entire sprinkler
assembly. Do not attempt to modify or
repair a damaged sprinkler.
Step 6.
Push on the Cover Plate
Assembly until its flange comes in
contact with the ceiling.
Do not continue to push on the Cover
Plate Assembly such that it lifts a
ceiling panel out of its normal position.
If the Cover Plate Assembly cannot
be engaged with the Mounting Cup
or the Cover Plate Assembly cannot
be engaged sufficiently to contact the
ceiling, the Sprinkler Fitting must be
repositioned.
Care and
Maintenance
The TYCO RAPID RESPONSE
Series LFII Residential Concealed
Pendent Sprinklers (TY3596) 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
which 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 a Cover Plate may delay the
sprinkler operation in a fire situation.
When properly installed, there is an air
gap between the lip of the Cover Plate
and the ceiling. The Ordinary Tem-
perature Cover Plate assembly has a
nominal 1/8 in. (3,2 mm) air gap. The
Intermediate Temperature Cover Plate
has a nominal 3/32 (2,4 mm) air gap,
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 re placed,
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.
Sprinklers which 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 before, during, and after instal-
lation. Sprinklers damaged by drop-
ping, 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
ASSOCIATION, for example, NFPA 25,
in addition to the standards of any other
authorities having jurisdiction. Contact
the installing contractor or product
manufacturer with any questions.
The owner must assure that the sprin-
klers are not used for hanging any
objects and that the sprinklers are only
cleaned by means of gently dusting
with a feather duster; otherwise, non-
operation in the event of a fire or inad-
vertent operation may result.
Automatic sprinkler systems should be
inspected, tested, and maintained by a
qualified Inspection Service in accor-
dance with local requirements and/or
national codes.
