Care and
Maintenance
The Series DS-2 Dry Type Sprinklers
must be maintained and serviced in
accordance with the following instruc-
tions:
NOTES
Absence of the outer piece of an es-
cutcheon, which is used to cover a
clearance hole, may delay the time to
sprinkler operation in a fire situation.
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 systems must
be obtained from the proper authori-
ties and all personnel who may be
affected by this action must be notified.
A Vent Hole is provided in the Bulb
Seat (Ref. Figure 1) to indicate if the
Dry Sprinkler is remaining dry. Evi-
dence of leakage from the Vent Hole is
an indication that there may be
weepage past the Inlet seal and that
the sprinkler needs to be removed for
determining the cause of leakage (e.g.
an improper installation or an ice plug).
The fire protection system control
valve must be closed and the system
drained before removing the sprinkler.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
shipped or stored where their tem-
perature will exceed 100°F/38°C and
they must never be painted, plated,
coated, or otherwise altered after leav-
ing the factory. Modified sprinklers
must be replaced. Sprinklers that have
been exposed to corrosive products of
combustion, but have not operated,
should be completely cleaned by wip-
ing the sprinkler with a cloth or by
brushing it with a soft bristle brush.
Care must be exercised to avoid dam-
age - before, during, and after instal-
lation. Sprinklers damaged by drop-
ping, striking, wrench twist/slippage,
or the like, must be replaced. Also,
replace any sprinkler that has a
cracked bulb or that has lost liquid from
its bulb (Ref. Installation Section).
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 Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any other
authorities having jurisdiction. The in-
stalling contractor or sprinkler manu-
facturer should be contacted relative
to any questions.
It is recommended that automatic
spr inkler systems be inspected,
tested, and maintained by a qualified
Inspection Service.
