Combined (smoke-heat) optical-electronic point explosion-proof fire detector IP 212 / 101-116.4-A1 Redoubt MK is intended for installation in places where it is impossible to predict unambiguously the occurrence and development of a fire (primary occurrence of smoke or temperature rise).Compensation for dustiness in the smoke chamber ensures that the detector's sensitivity remains at the set level and that there are no false alarms, as well as significantly increases the periods of operation between maintenance.The detector complies with TR CU 012/2011, TR EAEU 043/2017, GOST R 53325-2012.
The detectors are designed for operation at ambient temperatures from minus 40 ° С to plus 75 ° С, type of climatic modification is UHL category 2, relative air humidity is 93% at a temperature not exceeding 40 ° С.Atmospheric pressure from 84 to 106.7 kPa.Seals and joints of the detector body structural elements ensure the degree of protection in accordance with GOST 14254-2015 (IEC 60529: 2013) "Degree of protection provided by enclosures (IP Code)" of the switch compartment - not less than IP67; smoke chamber - not less than IP31.
The detector has an explosion protection type "flameproof enclosure" d "" and "intrinsically safe electrical circuit" ib "" (external smoke detector).Depending on the category of explosive mixture IIB and IIC, the enclosure design is divided into two types in accordance with the requirements of GOST IEC 60079-1-2011.Explosion protection marking according to GOST 31610.0-2014 (IEC 60079-0: 2011): 1Ex d [ib] IIB T6 Gb and 1Ex d [ib] IС T6 Gb.Case material - aluminum alloy with total magnesium content, titanium zirconium - not more than 7.5%.
The detector can be installed in hazardous areas of premises and outdoor installations according to the classification of GOST IEC 60079-10-1-2011 and other directive documents regulating the use of electrical equipment in hazardous areas.The environment may contain explosive mixtures of gases and vapors with air, categories IIA, IIB and IIC.
In terms of the method of protecting a person from electric shock, the detector corresponds to class III according to GOST IEC 61140-2012.
The detectors comply with the standards and requirements for electromagnetic compatibility in accordance with GOST R 53325 with test severity 2. Radio interference from the detector does not exceed the standards established by GOST 30805.22-2013 (CISPR 22: 2006) for class B equipment.
IP 212 / 101-116.4-A1 Redoubt MK is a detector of maximum differential action and can be used in alarm loops for closing (parallel connection).
