1 PURPOSE
The DUR-4047 radio universal optical smoke detector is designed for detection of 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 appearance of an
open flame and a noticeable rise in temperature. The detector is characterised by high resistance
against wind, pressure change and is very sensitive to visible smoke.
The DUR-4047 radio optical smoke detectors interoperate with the POLON 4000 fire detection and
alarm system control panels through the ACR-4001 radio adapter. The detectors are power supplied
with batteries.
The detector application is recommended when detectors cannot be connected to detection lines,
e.g. in historic buildings, churches, etc.

4 DESIGN DESCRIPTION
The DUR-4047 detector mechanical construction is shown on Fig. 1. Its basic part is a detecting
optical module consisting of a transmitting diode and a receiving diode. They both are mounted in a
holder in such a way that the light emitted by the transmitting diode does not reach the other diode
directly. The detecting module (holder with diodes) is fastened directly to a printed board that
contains all electronic elements with the detector operation monitoring processor. The optical
module penetration by external light is eliminated with a help of a labyrinth. 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 consisting of a basket, a detector cover and a screen.
The DUR-4047 detector is mounted on ceilings using the G-40 base (without clamps) which is
delivered together with the detector.

5 PRINCIPLES OF OPERATION
The DUR-4047 optical smoke detector operation basis is the Tyndall effect –light ray scattering on
smoke particles. Its basic element is a detecting optical module consisting of an electroluminescence
diode that transmits light radiation and a photodiode acting as a receiver. The optical module and
the 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 into digital form and then analysed by the microprocessor installed
inside the detector. An alarm mode is indicated with a pulse red light emitted by a diode installed in
the detector casing. The indicator enables fast location of the activated detector and is helpful in
periodic detector inspections.
Communication between the POLON 4000 system control panel and the DUR-4047 detectors is
obtained through the ACR-4001 radio adapter. The smoke detector communicates with the adaptor
using the radio protocol with confirmation and a possibility of changing the radio channel. During
operation, radio interferences are monitored and in an event of an interference occurrence, the
radio channel is changed, which allows the detector further uninterrupted operation. Apart from
transmitting an evaluation of fire factors and their change tendency, the detector passes to the
control panel, on its request, a 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 DUR-4047 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 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 alarm mode is signalled with a flashing red light of the illuminating diode. A fault mode,
a technical alarm and the battery fault are signalled with yellow flashes of the diode. The detector

6 IK-E315-001E
indicates the battery fault in case one of the installed batteries is taken out or when a battery
approaches the end of its operational period (one month prior to the genuine discharge and
impossibility to continue its work).
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 SERVICING CONDITIONS
The DUR-4047 batteries should be fixed only after the fire detection and alarm system installation
and configuration. Earlier battery connection in detectors that are unable to communicate with an
adapter may result in their fast discharge.
The DUR-4047 radio detector is power supplied with two 3 V batteries of CR123A type. It is
recommended to use batteries manufactured by Kodak (K123LA), Sanyo (CR123A), Energizer (EL123)
and Duracell (DL123A). The batteries delivered by the manufacturer, Polon-Alfa company, may be
purchased separately, in order to replace discharged ones already installed in detectors.
In case of battery replacement, it is necessary to exchange a set –2 batteries. The discharged
batteries must not be disposed as industrial waste; it is obligatory to obey environment protection
regulations in force (European Union directives No. 91/157/EWG and 93/86/EWG).
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.
For the period of repair works, the detector should be taken out or protected with
appropriate 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 DUR-4047 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 once in 6 months.
The detector operation is checked with a smoke simulator or smoke generator.
The DUR-4047 optical smoke detector long-lasting operation 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 a technical alarm mode sending excessive
contamination information to the control panel. It causes a necessity to clean the detector optical
module: the labyrinth and lenses of both diodes –the transmitting one and the photodiode. The
chamber contamination evaluation, before a technical alarm signalisation, can be carried out from
the control panel through contamination value readout from the control panel service function. A
failure to perform the servicing works may result in false alarm evoking in future.
The detector assembling and dismantling is shown on Fig. 2. In order to dismantle the detector it is
necessary to:
a) pressing the net long tongue, turn the cover right in the basket until it is taken out;

IK-E315-001E 7
b) remove two screws that fix the labyrinth and take the labyrinth out;
c) perform the necessary cleaning.
Fig. 2 Detector elements after dismantling
A delicate brush as well as vacuum cleaner is 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.

8 IK-E315-001E
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) lay down the basket in the reverse position as that shown on the figure;
c) insert the net into the basket paying attention to its positioning –alignment with the
tongues;
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 DUR-4047 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.
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.
8 RADIO SET COMMISSIONING (ACR-4001 ADAPTER + DUR-4047 DETECTORS)
The DUR-4047 detectors and the ACR-4001 adapter disposition is critical; any obstacle in the form of
walls, ceilings, doors or windows results in radio signal damping and in the worst case can reduce the
operation range from 100 m down to just few meters in case of unfavourable detector arrangement
in the building.
It should be ensured that not more than two adapters operating in the same more are installed in
radio range, i.e. consecutive adapters placed one next to another should be programmed to
operate in ‘1’, ‘3’, ‘5’ or ‘9’ mode. The modes from ‘3’ to ‘10’ are available only for adapters
supported with software not older than v. 1.3 and for detectors with software version not lower
than v. 1.4. For detectors supported with software versions of v. 1.0, v. 1.1 and v. 1.2 it is possible
to choose the adapter’s ‘1’ or ‘2’ mode only. The ‘1’ mode is not recommended due to highest
number of interferences from neighbouring frequency bands coming from other radio spectrum
users.

The above table presents corresponding operation modes: in the time of normal work and during
testing. For a given operation mode pair (e.g. 3 –4), the detector and the adapter work at the same
frequency set. In case the adapter’s operation mode is changed for another one (of a non-
corresponding pair), then ‘lack of communication with the detector’ fault may occur for several
minutes (if the detector was earlier furnished with batteries). Therefore, operation mode choice
choices should be made at the design stage, in accordance with the rule that the neighbouring
adapters (in radio range) are set up with different operation modes: consecutively ‘1’, ‘3’, ‘5’, ‘7’ and
‘9’.
When the DUR-4047 detector and ACR-4001 adapter are mounted in historic buildings, due to the
devices working conditions (signal damping value) that may be hard to estimate, it is necessary to
simulate the devices disposition in advance.
I. The devices mounting place choice is based on estimation: the detector and the adapter ‘see’
each other –there are no obstacles between them and the distance is smaller than 60 m.
II. The adapter mounting place choice –when the detector’s (detectors’) location is known –should
be made using the TZCR-4001 testing radio set (supplied from battery, with purposely worsened
radio spectrum parameters –in order to ensure unfailing work of a real adapter). After the
detector (with batteries connected) inserting into the base where it is intended to operate,
communication between the detector and adapter is checked (red flashes are emitted by a diode
placed in the adapter –minimum 1 red flash to provide 30 dB damping margin) using the testing
adapter.
Since the adapter communicates with every detector in its operation range, during the test only
one detector should operate!
III. The disposition choice, when the adapter mounting place is known and the detectors
arrangement can be altered.
Testing communication between the adapter and the detector, it is advised to carry out the
device tests at the level as close as possible to the real conditions (under the ceiling, not just
above the floor).
The devices commissioning should start from the radio adapter connecting into the POLON 4000
control panel detection line. None detector should be furnished with batteries. In order to check
the signal strength in the premises where the detectors are to be mounted, one detector should
be used.
1. At the control panel level, numbers of all detectors that are to interoperate with a given adapter
(max. 16 detector numbers) should be entered. For the purpose of this, it is necessary to choose
at the control panel (at the 3rd access level) the ‘SYSTEM CONFIGURATION -> LINE SETUP -> ACR
CONFIGURATION’menu.
a) The number of the line, where the adapter is installed, should be chosen;
b) The factory serial number should be entered –after its confirmation, the current adapter
configuration shall be read in and displayed;
c) At 1 –16 positions the numbers of the detectors interoperating with the adapter should be
written in.
Note: Special attention should be given to avoid the same detector assignment to two
different adapters as it may cause serious problems during configuration.
d) The ACR adapter configuration should be saved.
e) In case of such necessity, the a), b), c) and d) actions should be repeated for other radio
adapters.
2. In the control panel menu (at the 3rd access level), it is necessary to choose the ‘SYSTEM
CONFIGURATION -> LINE SETUP -> AUTOMATIC CONFIGURATION’ menu and to pursue automatic
elements declaration for a particular detection line. The control panel may signal detector faults

10 IK-E315-001E
as batteries are not connected and the detectors do not function.
Note: Since wireless radio detectors constitute a line branch, AUTOMATIC CONFIGURATION is
possible only when the adapter in installed in a loop-shaped detection line. If it is installed in a
radial line, only manual configuration can be carried out.
3. In the control panel menu (at the 3rd access level), it is necessary to choose the ‘SYSTEM
CONFIGURATION -> LINE SETUP -> MANUAL CONFIGURATION’ menu and to settle the ACR-4001
adapter’s ‘2’ operation mode (alternatively ‘4’, ‘6’, ‘8’ or ’10’ – service modes). A collective
‘TESTING’ indicator is lit in the control panel and, after pressing the button located near the
indicator, an ‘ACR-4001 IN SERVICE MODE’ communique is displayed.
4. One of the declared detectors should be furnished with batteries. As soon as the detector enters
the adapter operation range, the indicating diode emits red modulated flashes. In case the
detector is unable to establish communication with the adapter, the diode emits modulated
yellow flashes. The number of red flashes indicates the signal level (from 1 to 3).
5. It is necessary to test, whether proper radio communication with the adapter is established in the
place where the detector is to be installed –regular 3 diode red flashes and no yellow flashes.
Additionally, it is possible to check in the control panel ‘SYSTEM ELEMENTS TESTING -> TESTS
SETUP -> COMMUNICATION WITH RADIO DETECTOR TEST’ menu, the number of successful
attempts out of latest 31 ones. Optimally the ‘COMMUNICATION QUALITY’ parameter value
should amount to 31; it cannot be lower than 20. Three minutes should be provided for reaching
the proper value and its stabilization. Additionally, the ‘TRANSMISSION HISTORY’ enables latest
transmissions history analysis. In order to provide 30-dB radio band damping, the graph columns
should be of maximum height.
Note: The ‘TRANSMISSION TIME’ parameter should not exceed 10 sec.; if the parameter
amounts to more than 60 sec. for the whole 3-minute test period, it is necessary to ascertain
that the adapter operates in the ‘2’ (or ‘4’, ‘6’, ‘8’,’10’) mode.
6. Subsequently, the detector should be placed in a consecutive base and its transmission
correctness should be checked as in p. 5.
7. When all the places where detectors are to be installed are checked, the detectors should be
furnished with batteries and mounted in the bases which were determined beforehand. It is
important to prove at the control panel that every communication fault with the installed
detectors has been eliminated.
8. After confirmation that the whole circuit operates properly, the control panel should be set up in
the ‘SYSTEM CONFIGURATION -> LINE SETUP -> MANUAL CONFIGURATION’ menu at the ‘1’ mode
(or ‘3’, ‘5’, ‘7’, ‘9’ – normal operation mode) of the ACR-4001 adapter. The collective ‘TESTING’
indicator should go out; if it does not happen, it is necessary to check whether, after pressing the
button located near the diode, the communique ‘ACR-4001 IN SERVICE MODE’ is still displayed, or
another test is being executed.
Note: In case a detector is located in a place where radio communication is hindered (i.e. the
detector does not receive a confirmation of every information sent –it receives for instance one
confirmation per 20 transmission attempts), it can result in faster batteries discharge and the
detector shortened operational period. Low transmission quality is indicated at the control
panel by the ‘LOW RADIO LINK QUALITY' technical alarm.
STORAGE AND TRANSPORTATION
8.1 Storage
The DUR-4047 detectors should be kept in closed premises free of caustic gases and vapours at the
temperature between +0 °C and +40 °C, and relative humidity not exceeding 80 % at +35 °C.
