Overview

Details

Marine Intelligent Base Mounted IR³ Flame Detector

The Intelligent Base Mounted IR3 Flame Detector is designed to protect all indoor areas, even in dirty or smoky conditions where open flaming fires may be expected. The detector has three IR sensors that respond to different IR wavelengths in order to discriminate between flames and spurious sources of radiation.

Electrical Description

The detectors are loop powered and need no external supply. A remote LED alarm indication may be connected to the flame detector.

Operation

The detector is sensitive to low-frequency, flickering infra-red radiation emitted by flames during combustion. Since it responds to flickering radiation the detector can operate even if the lens is contaminated by a layer of oil, dust, water-vapour or ice. The detector is set to respond to low-frequency radiation at 1−15Hz (0.75−2.7μm) in order to detect all flickering flames, including those invisible to the naked eye, e.g. those emitted by hydrogen fires. The detector has three IR sensors that respond to different IR wavelengths in order to discriminate between flames and spurious sources of radiation. False alarms due to factors such as flickering sunlight are avoided by a combination of filters and signal processing techniques.

Application

The triple IR flame detector is also fast reacting but is also tolerant of fumes, vapours, steam, dust and mist, while being unaffected by the phenomena listed above. It may, however, be affected by modulated IR radiation. Triple IR flame detectors are used in waste handling, colour printing and paper manufacturing.

Backward Compatibility

The detectors operate only with control equipment using the Apollo XP95 or Discovery digital protocol (or any development of it).
