Communication
between
the
POLON
4000
fire
alarm
control
panel
and
the
DOR
‐
4046
detectors
is
obtained
with
an
addressable
two
‐
wire
detection
line.
Unique,
fully
digital
communication
protocol
enables
passing
any
information
from
the
fire
alarm
control
panel
to
the
detector
and
inversely.
Apart
from
transmitting
an
evaluation
of
fire
factors
and
tendency
of
their
changes,
the
detector
passes
to
the
control
panel,
on
its
request,
the
current
analogue
value.
The
detector
operation
controlling
microprocessor
monitors
correctness
of
its
basic
circuits
operation
and,
in
case
an
irregularity
is
found,
reports
relevant
information
to
the
control
panel.
The
DOR
‐
4046
is
an
analogue
detector
with
an
automatic
sensitivity
self
‐
regulation
digital
mechanism
that
is
it
maintains
a
constant
sensitivity
level
during
progressing
dirt
build
‐
up
in
the
measuring
chamber.
After
exceeding
a
pre
‐
set
threshold
of
technical
alarm,
the
detector
transmits
a
signal
to
the
POLON
4000
system
control
panel
denoting
the
measuring
chamber
partial
contamination.
The
signal
is
generated
in
order
to
inform
the
servicing
personnel
that
the
detector
parameters
shall
not
remain
at
the
declared
level
in
case
the
dirt
build
‐
up
tendency
is
maintained
and
appropriate
measures
are
not
taken.
It
must
be
stressed
that
the
detector
shall
be
fully
efficient
within
ca.
1/3
of
the
time
period
that
passed
since
the
latest
maintenance
works.
The
detector
is
equipped
with
an
internal
short
circuit
isolator
that
cuts
off
an
efficient
part
of
a
detection
line
from
the
adjacent
shorted
section
what
enables
further
undisturbed
detector
operation.
The
detector
alarm
mode
is
signalled
with
flashing
red
light
of
the
illuminating
diode.
The
fault
mode,
technical
alarm
and
an
actuation
of
a
short
circuit
isolator
are
signalled
with
yellow
flashes
of
the
diode.
The
detector
sensitivity
level
is
adjustable.
Its
sensitivity
is
settled
from
the
control
panel
level
choosing
one
of
available
sensitivity
levels:
1
st
operation
mode
–
normal
sensitivity,
2
nd
operation
mode
–
increased
sensitivity,
3
rd
operation
mode
–
decreased
sensitivity.
The
detector
operation
modes
(besides
the
control
panel
alarm
variants)
entails
that
the
user
is
able
to
adapt,
in
the
best
way,
its
operation
characteristics
to
operation
in
the
determined
environment.

OPERATION
AND
MAINTENANCE
CONDITIONS
During
the
detectors
operation
it
is
obligatory
to
avoid
creation
of
dew
or
rime
on
the
detector
surface
as
well
as
to
protect
against
excessive
contamination
with
dust.
In
the
time
of
any
repair
works,
the
detector
should
be
taken
out
or
protected
with
provided
‐
for
‐
this
‐
purpose
cover.
Such
a
cover
can
be
obtained
from
an
installer
or
purchased
from
the
manufacturer.
In
case
the
detector
is
taken
out,
its
base
should
be
protected
against
being
painted
utilising
a
painting
tape.
Detectors
which
are
damaged
during
painting
and
renovation
works
due
to
a
fault
of
the
persons
executing
such
works
(e.g.
painted
detector
casing,
stuck
‐
with
‐
paint
net,
etc.)
are
not
subject
to
warrant
repairs.
During
the
operation
life,
the
DOR
‐
4046
addressable
optical
smoke
detector
should
be
subjected
to
periodical
inspection
according
to
PKN
‐
CEN/TS
54
‐
14:2006
standard,
which
is
executed
in
order
to
confirm
the
detector
proper
operation
and
its
appropriate
interoperation
with
the
control
panel.
The
inspection
should
be
carried
out
at
least
every
6
months.
The
detector
operation
is
tested
with
a
smoke
simulator
or
smoke
generator.
Long
‐
lasting
operation
of
the
DOR
‐
4046
optical
smoke
detector
may
result
in
dust
accumulation
inside
its
internal
optical
chamber.
After
exceeding
the
self
‐
regulation
range
due
to
the
chamber
contamination
