CO and NO2 GAS DETECTION SYSTEM USING ELECTROCHEMICAL SENSOR The new DURPARK series of control panels have been designed specially for use in car parks and small installations. It allows for the simultaneous detection of CO and NO2 in the same loop, being able to control up to 16 detectors with the possibility of programming up to 2 groups, making it possible to carry out individual maneuvers in the case of different gases, or sectorize maneuvers in the case of the same gas being detected. The installation of the detectors is carried out in parallel, with any type of branching being allowed. In its 4 module line version up to 12,800m2 (CO) can be covered in accordance with current Spanish standards. Each detector is monitored individually, showing its status in real time on the display. Module lines, independently. A programmable function is incorporated that allows leaving the detectors in test mode so they will not carry out the maneuvers in case of breakdown or lack of maintenance. A non-expandable DURPARK MINI version with one module line is also available, with the same characteristics than the expandable model. MAIN CHARACTERISTICS u Expandable from one to four totally independent module lines. u Two tension free switched relay outputs per module line for maneuvers, fuse protected. u Detector communication through 3 wires, allowing detectors to be addressed. u One tension free switched alarm output per module line, fuse protected. u Information is presented in real time, in a 16x2 character line LCD backlit display. u One general fault output. u Three optical indications: general fault, inhibited acoustics and ventilation status. u 13.8V 3,4A power supply source capable of controlling the presence, charge and status of a battery of up to 12V 7,5Ah. u Factory programmed with Spanish or Portuguese standards with the possibility of programming for Spanish, Portuguese, French and English languages (depending on software version). DURPARK DETECTOR This detector includes a new type of electrochemical sensor with a low cost and great performance that allows for a useful life period of up to 5 years (CO) and 3 years (NO2) almost without maintenance. Specially designed for use in car parks. Two models in two versions are available. One model for CO detection with a range of 0-300 ppm and a resolution of ±1 ppm, and another model for NO2 detection with a range of 0-20ppm and a resolution of ±0.5 ppm, both with a 3-wire communications format and addressable. In these detectors, maintenance and calibration have been simplified, algorithms have been created for automatic zero and gain calibration through software, as well as an algorithm and special hardware that allows verifying CO sensor sensibility without the need to apply gas. For the CO detector, the composition of its electrolyte is respectful of the environment, its structural form cancels the risk of the electrolyte leaking, it does not use active materials in its electrodes during operation, it has a lower sensitivity to interfering gases, long life and good stability and accuracy.
