b)
remove
two
screws
that
fix
the
labyrinth
and
take
the
labyrinth
out;
c)
perform
the
necessary
cleaning.
A
delicate
brush
as
well
as
vacuum
cleaner
are
recommended
for
cleaning.
Compressed
air
can
be
possibly
used.
It
is
permitted
to
wash
the
labyrinth
with
warm
water
with
addition
of
washing
‐
up
liquid.
No
damp
patches
should
remain
on
the
labyrinth
internal
surfaces
after
washing
and
drying.
After
cleaning
the
detector
should
be
assembled,
its
functioning
should
be
tested
using
a
smoke
imitator
or
smoke
generator
and
installed
again
into
the
detection
line.
In
this
order
to
assemble
the
detector,
it
is
necessary
to:
a)
fasten
the
labyrinth
with
two
screws;
b)
place
the
basket
in
the
reverse
position
as
that
shown
in
the
figure;
c)
insert
the
net
into
the
basket
paying
attention
to
its
positioning
–
alignment
with
the
juts;
d)
insert
the
cover
into
the
basket
so
that
the
illuminating
diode
is
placed
a
little
to
the
right
in
relation
to
the
glass;
e)
turn
the
cover
to
the
left.
Note
–
In
case
the
cleaning
does
not
produce
the
required
result,
it
is
necessary
to
send
the
detector
to
the
manufacturer
for
repair.

DETECTOR
INSTALLATION
The
DOR
‐
4046
detectors
are
installed
(height,
arrangement)
according
to
the
guidelines
settled
by
the
Scientific
and
Research
Centre
for
Fire
Protection.
They
are
mounted
in
premises
where
the
working
equipment
or
stored
materials
may
emit
visible
smoke
when
a
fire
occurs.
In
case
it
is
difficult
to
determine
the
most
probable
fire
factor
(smoke
type)
that
is
likely
to
occur
in
the
first
fire
development
phase,
special
tests
should
be
carried
out
(at
a
designing
stage)
using
various
type
detectors
or
mixed
protection
(e.
g.
with
optical
and
ionisation
detectors)
should
be
applied.
The
detectors
are
intended
to
operate
in
loops,
in
loops
with
straight
branches
or
in
radial
detection
lines
of
the
POLON
4100
and
POLON
4200
control
panels
(see
the
POLON
4100/POLON
4200
control
panel
Operation
and
Maintenance
Documentation).
The
detectors
are
installed
in
the
40
model
range
bases.
The
detection
line
connection
is
presented
in
the
G
‐
40
base
Installation
and
Maintenance
Manual.
An
additional
optical
alarm
signal
of
a
detector
or
a
group
of
detectors
can
be
obtained
by
connecting
the
WZ
‐
31
alarm
indicator.
Alarm
system
cables
are
routed
in
accordance
with
the
regulations
obligatory
for
low
voltage
(below
42
V)
systems.
Note
–
The
detectors
should
not
be
installed
in
corrosive
atmosphere
that
contains
caustic
gases
and
vapours
as
well
as
dust.
Steam
condensation
on
detectors
is
impermissible.

STORAGE
AND
TRANSPORTATION
8.1
Storage
The
DOR
‐
4046
detectors
must
be
stored
in
closed
rooms
free
of
any
caustic
gases
and
vapours,
at
ambient
temperature
between
0
°C
and
+40
°C
and
relative
humidity
not
exceeding
80
%
at
+
35
o
C.
