Care and
Maintenance
TYCO Model FSC 80 K-factor Flush
Sprinklers must be maintained and ser-
viced in accordance with this section:
Service inspections should be made
on a regular basis to detect possible
damage or alterations to the sprin-
kler and escutcheon. Inspections
should include making certain that the
escutcheon is held fast to the mount-
ing surface. Damaged or altered sprin-
klers are to be replaced immediately
to avoid personal injury and to prevent
use for causing personal injury, as well
as to maintain the sprinkler system in
an operative condition.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system
that it controls, obtain permission to
shut down the affected fire protection
system from the proper authorities
and notify all personnel who may be
affected by this action.
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 other-
wise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
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.
Frequent visual inspections are recom-
mended to be initially performed for
sprinklers installed in potentially corro-
sive atmospheres to verify the integrity
of the materials of construction as they
may be affected by the corrosive con-
ditions present for a given installation.
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 approval agency and standards
of any other authority having jurisdic-
tion. Contact the installing contrac-
tor or product manufacturer with any
questions.
Sprinklers are recommended to be
inspected, tested, and maintained by
a qualified Inspection Service in accor-
dance with local requirements and/or
national codes.
