Sprinklers must be maintained and
serviced in accordance with the fol-
lowing instructions:
NOTICE
Service inspections should be made
on a regular basis to detect possible
damage or alterations to the sprinkler
and escutcheon. Inspections should
include making certain that the Insti-
tutional Escutcheon is held fast to the
mounting surface. Damaged or altered
sprinklers are to be replaced immedi-
ately to avoid personal injury and to
prevent use for causing personal inju-
ry, as well as to maintain the sprinkler
system in an operative condition.
Before closing a fire protection sys-
tem main control valve for mainte-
nance work on the fire protection sys-
tem that it controls, permission to shut
down the affected fire protection sys-
tems must be obtained from the prop-
er authorities and all personnel who
may be affected by this action must be
notified.
Sprinklers which are found to be leak-
ing or exhibiting visible signs of corro-
sion 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 dam-
age to the sprinklers -before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be
replaced.
The owner is responsible for the in-
spection, testing, and maintenance
of their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Pro-
tection Association (e.g., NFPA 25), in
addition to the standards of any oth-
er authorities having jurisdiction. The
installing contractor or sprinkler man-
ufacturer should be contacted relative
to any questions.
Automatic sprinkler systems should
be inspected, tested, and maintained
by a qualified Inspection Service in
accordance with local requirements
and/or national codes.
