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

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

The 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.

Operation:

The Orbis range incorporates seven heat detector classes to suit a wide variety of operating conditions in which smoke detectors are unsuitable. The European standard EN54-5:2001 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 Features:

• Can be used for applications where smoke detectors are unsuitable
• Ideal for environments that are dirty or smoky under normal conditions
