Marine Intelligent Base Mounted UV IR² Flame Detector

Product code: 55000-028MAR

55000-028MAR - Marine Intelligent Base Mounted UV IR² Flame Detector
The Marine Intelligent Base Mounted UV Dual IR Flame Detector is designed to protect open indoor areas where open flaming fires may be expected. The detector has a UV and dual IR sensors responding to different wavelengths in order to discriminate between flames and spurious sources of radiation.
Full Details
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 ultraviolet and low-frequency, flickering infra-red radiation emitted by flames during combustion. Since it requires both UV and IR radiation the detector can operate in applications where a basic single UV or single IR detector would be inappropriate. The detector is set to respond to ultraviolet (185−260nm) and low-frequency flickering infra-red (0.75−2.7μm) radiation at 1−15Hz in order to detect all flickering flames, including those invisible to the naked eye, e.g. those emitted by hydrogen fires. The detector has one UV and two IR sensors responding to different wavelengths in order to discriminate between flames and spurious sources of radiation. False alarms due to electrical discharges from lightning or arc welding and flickering sunlight are minimised by combining the UV/IR signals.

Application

This detector is not affected by any of the sources mentioned above. They are used in aircraft hangers, generator rooms (diesel and gas turbines) and paint works.

Product Information

The Marine Intelligent Base Mounted UV Dual IR Flame Detector is designed to protect open indoor areas where open flaming fires may be expected. The detector has a UV and dual IR sensors responding to different wavelengths in order to discriminate between flames and spurious sources of radiation.

Key Features

Responds to stationary flames with no flicker Sensitive to low-frequency flickering IR radiation emitted by flames during combustion. Compact flame detector which fits into Discovery Marine bases Loop-powered False alarms due to factors such as flickering sunlight are avoided by a combination of filters and signal processing techniques
