The Intelligent IR3 Flame Detector is designed to protect areas where open flaming fires may be expected. It is sensitive to low frequency, flickering infra-red radiation emitted by flames during combustion. Since it responds to flickering radiation the IR Flame Detector can operate even if the lens is contaminated by a layer of oil, dust, water-vapour or ice. The Intelligent IR Flame Detector is set to respond to low-frequency radiation at 1 to 15Hz (1 to 2.7m) in order to detect all flickering flames, including those invisible to the naked eye, eg, those emitted by hydrogen fires. The Intelligent IR Flame 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 such factors as flickering sunlight are avoided by a combination of filters and signal processing techniques. Flame detectors are used when detection is required to be unaffected by convection currents, draughts or wind; tolerant of fumes, vapours, steam, dust and mist; responsive to a flame more than 25m away and fast reacting. Before installing the flame detector, it is necessary to set the address using the DIL switch, which is accessed by removing the front cover, using a 5mm hexagonal key. 7 segments of the switch are set to 0 or 1, using a small screwdriver or similar tool. A complete list of address settings is shown in the Installation Guide (PP2271). The Intelligent IR Flame Detector operates only with control equipment using the Apollo XP95 or Discovery digital protocol (or any development of it).
