Monogase DMG-3 detector (CO, O2)

The CO detector is designed to detect the excess of the established thresholds for the content of carbon monoxide (OC) in the air of controlled premises. The O2 detector is designed to signal a lack of oxygen in the air. For example, in the residential sector of public utilities, garages of motor vehicles, closed underground parking lots, etc. When the threshold values of the concentration of the detected gas (or a decrease in the concentration of oxygen) in the monitored area are reached, the device switches to the emergency mode. (or warning) light alarm. Carbon monoxide detector is available in four versions: "DMG-3", "DMG-3M", "DMG-3R", "DMG-3MR". Oxygen detector: DMG-3K and DMG-3KR. DMG-3, DMG-3R have an operating temperature range from minus 10 to plus 50 ° СDMG-3M and DMG-3MR – have an operating temperature range from minus 40 to plus 50 ° СDMG-3K and DMG-3KR – an operating temperature range from 0 up to plus 40 ° C. All other technical characteristics of the detector versions are the same. Those. specifications Operating conditions of detector operation Ambient temperature, ° С from minus 10c to plus 50c for DMG-3, DMG-3R From minus 40c to plus 50c for DMG-3M, DMG-3MR From zero to plus 40C for DMG-3K, KR Relative ambient humidity at a temperature of 25 ° С,% to 80 atmospheric pressure, kPa from 84 to 106.7 (from 630 to 800 mm Hg) the content of corrosive agents is not higher than the permissible values for an atmosphere of type I (conditionally clean) according to GOST 15150-69 Main parameters. The method of sampling by the detector is diffusion. Operation mode is continuous. Detection range, mg / m3 from 0 to 250. Maximum permissible concentration level, mg / m3. 250. signaling, s, no more * 60 Current consumption, no more, A 0.03 Power consumption, V * A, no more than 6.6 Class of protection against electric shock BI (according to GOST IEC 61140-2012) Communication interface RS-485 Degree of protection of the enclosure: IP65 ( for civil defense ST 14254-2015) Overall dimensions, mm, no more than 120x104x55 Weight, kg, no more than 0.4
