Apollo Marine Orbis BS Heat Detector - ORB-HT-41004-MAR

Apollo Marine Orbis BS Heat Detector - ORB-HT-41004-MARThe Orbis Marine Heat Detector uses a single thermistor to sense the air temperature around the detector. There are twelve heat detectors in the Orbis Marine range designed to suit a wide variety of operating conditions.OperationThe Orbis range incorporates seven heat detector classes to suit a wide variety of operating conditions in which smoke detectors are unsuitable. The European standard EN54-52001 classifies heat detectors according to the highest ambient temperature in which they can safely be used without risk of false alarm.The classes are identified by the letters A to G. Class A is subdivided into A1 and A2. In addition to the basic classification detectors may be identified by a suffix to show that they are rate-of-rise suffix R or fixed temperature suffix S types. All heat detectors in the Orbis range are tested as static or rate-of-rise detectors and are classified as A1R A1S A2S BR BS CR and CS.Key FeaturesCan be used for applications where smoke detectors are unsuitableIdeal for environments that are dirty or smoky under normal conditions
