- Page 2 2 IK‐E306‐001GB The DUR‐4046 optical smoke detector covered by the present manual, complies with the requirements of the following European Union Directives: CPD 89/106/EWG on construction materials; EMC 2004/108/WE on electromagnetic compatibility. The DUR‐4046 optical smoke detector has been approved with the EC‐Certificate of Conformity No. 1438/CPD/0011 issued by the Scientific and Research Centre for Fire Protection (CNBOP) Józefów, Poland, an EU notified authority No. 1438, confirming its compliance with the requirements of PN‐EN 54‐7:2004 standard. ...
- Page 3 IK‐E306‐001GB 3 1 PURPOSE The DUR‐4046 microprocessor based interactive addressable 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 a high resistance against wind, pressure change and steam condensation. It is very sensitive to visible smoke. The DUR‐4046 addressable optical smoke detectors operate only in the POLON 4000 fire detecting and alarm system control panel addressable loop‐shaped lines. The detectors are equipped in internal short circuit isolators. ...

Its basic element is a detecting optical module consisting of transmitting ultraviolet diode and a receiving diode. They are mounted in ...
- Page 5 IK‐E306‐001GB 5 Communication between the POLON 4000 system control panel and the DUR‐4046 detectors is obtained through an addressable two‐wire detection line. A unique, fully digital communications protocol enables passing any information from the control panel to the detector and inversely. Apart from transmitting an evaluation of fire factors and tendency of 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 ...

Fig. 2 Detector elements after dismantling 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; b) remove two screws that fix the labyrinth and take the labyrinth out; c) perform the necessary cleaning. ...
- Page 7 IK‐E306‐001GB 7 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. ...
