Restoring
the
System
The
following
activities
are
to
be
conducted
when
restoring
the
fire
‐
protection
system.
1.
Once
it
has
been
confirmed
that
the
fire
has
been
extinguished,
press
the
red
STOP
button
on
the
front
of
the
pump
controller
to
turn
off
the
fire
pump.
2.
Notify
remote
monitoring
entity
and
fire
brigade
that
the
water
mist
system
is
going
to
be
taken
out
of
service.
3.
Power
down
the
fire
pump
controller
by
closing
the
Circuit
Breaker
Switch
and
then
the
Isolating
Switch.
Verify
loss
of
AC
power
to
the
controller
is
indicated
on
the
Detection
and
Releasing
panel.
4.
For
system
equipped
with
a
pressure
maintenance
(jockey)
pump,
power
down
the
jockey
pump
by
switching
the
selector
switch
on
the
jockey
pump
controller
to
the
OFF
position.
5.
Close
the
isolation
valve
located
on
the
water
supply,
suction
side
of
the
pump
skid
and
verify
that
a
supervisory
signal
is
indicated
at
the
Detection
and
Releasing
panel.
6.
Clean
the
pump
skid
strainer
per
the
procedure
outlined
in
Annex
B.
7.
The
activated
nozzles
shall
be
removed
and
returned
to
FIKE,
the
thread
sealant
removed
and
new
nozzles
shall
be
installed
in
their
place.
It
is
recommended
that
activated
nozzles
be
replaced
by
nozzles
of
same
make
and
build
as
to
make
certain
that
the
correct
spacing
and
height
of
nozzle
is
achieved.
8.
Nozzles
in
the
adjacent
areas
of
the
activated
zone/nozzles
shall
be
visually
inspected.
This
requires
the
nozzles
to
have
intact
bulbs
with
a
sufficient
amount
of
liquid
within,
no
signs
of
any
leakages
and
retaining
a
small
spherical
concentration
of
air
within
the
liquid
at
room
temperatures,
i.e.
25°
C
±5
(
≈
68°
F
±10).
Nozzles
which
do
not
comply
with
above
mentioned
requirements
shall
be
returned
to
FIKE
and
new
nozzles
shall
be
installed
in
their
place.
Depending
on
the
situation
and
circumstances
which
actuated
the
fire
protection
system,
nozzles,
which
have
not
been
activated,
in
the
vicinity
of
the
activated
nozzles
may
have
been
contaminated
or
soiled
as
a
result
of
fire
or
other
chemical
reactions
in
the
vicinity
of
the
nozzles.
Because
of
the
sensitive
nature
of
the
bulb,
the
nozzle
is
not
to
be
cleaned
immediately.
A
photograph
of
the
nozzle
shall
be
sent
to
FIKE
of
which
will
determine
the
severity
of
the
contamination
and
whether
the
nozzle
should
be
cleaned
or
replaced/refurbished.
