1 PURPOSE
The DOR-4043 microprocessor based, interactive optical smoke detector is designed for detection of
a visible smoke that is concurrent with most fire combustion. It enables a fire detection at a start of its
flameless stage when material starts to smoulder, and therefore generally, a long time prior to the
appearance of an open flame and a noticeable rise in temperature. The detector is characterised by
a high resistance against wind, pressure change and steam condensation. It is very sensitive to visible
smoke.
The DOR-4043 addressable optical smoke detectors operate only in addressable lines/loops of the
POLON 4100 and POLON 4200 fire detecting and alarm systems. They are equipped with short circuit
isolators.

4 CONSTRUCTION DESCRIPTIONS
The detector mechanical construction is shown in Fig. 1. Its basic element is a detecting optical module
consisting of transmitting infrared diode and a photodiode acting as a receiver. They are mounted in
a holder in such a way that radiation emitted by the transmitting diode does not reach the other diode
directly. The detecting module (holder with diodes) is fastened to a printed board that contains all
electronic elements and a circuit with the detector monitoring processor. The optical module is
protected by a labyrinth, damping external radiation. A metal protective net prevents irruption of small
insects or pieces of dirt into the detecting module. The whole structure is placed in a white plastic
housing containing a basket, screen and detector cover.
The DOR-4043 detector is installed in the G-40 base where detecting line cables are connected to.

5 PRINCIPLE OF OPERATION
The DOR-4043 is a Tyndall effect based optical smoke detector –light ray scattering on smoke particles.
Its basic element is a detecting optical module consisting of an electroluminescence diode that transmits
infrared radiation and an optical receiving diode. The optical module and surrounding measuring
chamber are protected by a labyrinth which is shaped to dump both external light and radiation
resulting from internal reflexes of the transmitting diode light. When smoke particles enter the
measuring chamber, they reflect the light emitted by the transmitting diode. The reflected light reaches
the optical diode producing photocurrent which is first strengthened and processed, and then analysed
by the microprocessor installed inside the detector.
The alarm mode is indicated with pulse red light emitted by a signalling diode installed on the detector
casing. The indicator enables fast location of the activated detector and is helpful in periodic detector

5 IP-E282-002E
inspections. In case the detector is hardly visible or is installed in a difficult-to-reach space, an additional
optical alarm indicator (WZ-31) may be connected in an accessible and visible place.
Communication between the POLON 4100/POLON 4200 fire alarm control panel and the DOR-4043
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-4043 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: 1st operation mode –normal sensitivity, 2nd operation mode –
increased sensitivity, 3rd 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.
6 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 warranty repairs.
During the operation life, the DOR-4043 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.

6 IP-E282-002E
The detector operation is tested with a smoke simulator or smoke generator.
Long-lasting operation of the DOR-4043 optical smoke detector may result in dust accumulation inside
its internal optical chamber. After exceeding the self-regulation range due to the chamber contamination
progress, the detector triggers the technical alarm mode sending excessive contamination information to
the control panel. It causes a necessity to clean the detector optical module: the labyrinth and the lenses
of both diodes –transmitting one and photodiode. A failure to carry out the servicing works may result
in false alarm evoking in future.
Fig.2 Detector elements after dismantling

7 IP-E282-002E
The detector assembling and dismantling is shown in Fig. 2.
In order to dismantle the detector it is necessary:
a) pressing the net long tongue, to turn the cover right in the basket until it is taken out;
b) to remove two screws that fix the labyrinth and take the labyrinth out;
c) to 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.
7 DETECTOR INSTALLATION
The DOR-4043 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.
