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 Intelligent Base Mounted IR3 Flame Detector is loop powered and needs 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 fi res. 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 as flickering sunlight are avoided by a combination of filters and signal processing techniques.
Application
UV/IR² 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.
Backward Compatibility
The Detector operates only with control equipment using the Apollo XP95 or Discovery digital protocol (or any development of it).
Additional Information
ACCESSORIES A portable Flame Detector Test unit is available, part number 29600-226.
