It is advisable to have sprinkler
systems inspected regularly by a
qualified inspection service. Length
of time between such inspections can
vary due to accessibility, ambient
atmosphere, water supply, and site
activity.
Do not attempt to re-assemble or
otherwise reuse a sprinkler that has
operated. Replace any sprinkler
exhibiting corrosion or damage;
always use new sprinklers of the
same type and temperature rating as
replacements.
Because the discharge pattern is
critical to protection of life and
property, nothing should be hung or
attached to the sprinkler unit that
would disrupt the pattern. Such
obstructions must be removed. In the
event that construction has altered
the original configuration, additional
sprinklers should be installed to
maintain the protection level.
Do not attempt to replace sprinklers
without first removing the fire protec-
tion system from service. Be certain
to secure permission from all
Authori-
ties Having Jurisdiction, and notify all
personnel who may be affected
during system shutdown. A fire
watch during maintenance periods is
a recommended precaution.
To remove the system from service
mode, first refer to the system
operating guide and valve instruction.
Drain the water and relieve pressure
in the pipes. Remove the existing
unit and install the replacement, using
only the special sprinkler wrench. Be
certain to match model, style, orifice,
and temperature rating.
A fire protection system that has
been shut off after an activation
should be returned to service immedi-
ately. Inspect the entire system for
damage and replace or repair as
necessary. Sprinklers that did not
operate but were subjected to corro-
sive elements of combustion or
excessive temperatures should be
inspected, and replaced if need be.
The
Authority Having Jurisdiction will
detail minimum replacement require-
ments and regulations.
