Visually check the exterior of the detector for any mechanical or corrosive damage.
Flame detector Heat detector Smoke detector. While capable of detecting fires and explosions within 3—4 milliseconds, a time delay of 2—3 seconds is often included to minimize false alarms which can be triggered by other UV sources such as lightningarc weldingradiationand sunlight. Ensure the detector still has a clear line of sight of the area it is protecting and no obstacles obstruct its view.
Multiple channel or pixel array sensors monitoring flames in the near IR band are arguably the most reliable technologies available for detection of fires.
However the periodic maintenance steps listed below are essential to maintain reliable fire protection. Rinse with clean water and dry with a clean cloth. Reinstate any automatic system disabled during maintenance.
These electro-optical sensor combinations also enable the detection of non-hydrocarbons like hydrogen fires without the risk of false alarms caused by artificial light or electrical welding.
Industrial and Process Furnaces: A fire emits radiation, which human eye experiences as the visible yellow red flames and heat. The horizontal angle of vision and the vertical or3 of vision often differ; this is mostly caused by the shape of the housing and by mirroring parts meant for the self test. Compare 0 Products Add To Compare 0 of 4 max. Full details of our service standards can be downloaded here.
The hot CO 2 emits much detecttor at its resonance frequency of 4. Disable any automatic systems that may be activated by the flame detector if not required as part of the maintenance check.
Flame detection in video using fetector Markov models PDF. Further details may exist on the talk page. A flame detector can often respond faster and more accurately than a smoke or heat detector due to the mechanisms it uses to detect the flame. This allows the detector to distinguish between non-flame IR sources and actual flames which emit hot CO 2 in the combustion process.

Flame Detectors: Mini IR3 Flame Detector m Range MIF
The Intelligent IR3 Flame Detector is designed to protect areas where open flaming fires may be expected. Different combustibles can even have a different angle of vision in the same flame detector. It must be emphasized, however, that the square root in reality is not valid anymore at very high distances. A special frequency range is 4. Please email your order to us at: Also the shadow effect must be considered.
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. With this constant c can, for the same flame detector and the same type of fire, the maximum distance or the minimum fire area be calculated: Sensing the CO2 emission is appropriate for hydrocarbon fuels; for non-carbon based fuels, e.
Views Read Edit View history. Not all manufacturers of flame detectors use sharp filters for the 4. 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.
Mini IR3 Flame Detector 2.5-10 m Range 20-20MI-3-F
The cone of vision of a flame detector is determined by the shape and size of the window and the housing and the location of the sensor in the housing. Register or sign in to add products to your project list. False alarms due to such factors as flickering sunlight are avoided by a combination of filters and signal processing techniques.
Despite our best efforts, mistakes sometimes detedtor.
Most IR detectors are designed to ignore detectot background IR radiation, which is present in all environments. International Conference on Image Processing: The cause is similar to what a fire fighter does if he approaches a hot fire: As a result, both detection range and immunity lr3 false alarms can be significantly increased.
The range of a flame detector is highly determined by the mounting location. Stainless steel 2 axis adjustable mounting bracket, part no Disabling cookies may impair your experience of this website as some functionality relies on cookie information, and you may not be able to access certain areas of the site. Water on the detector’s lens will greatly reduce the accuracy of the detector, as will exposure to direct sunlight.
For some applications the flame detector needs to be aligned precisely to take care that it does not detect potential background radiation sources. This page was last edited on 19 Decemberat Thermocouples are used extensively for xetector flame presence in combustion heating systems and gas cookers. If a flame detector can detect a fire with an area A on a certain distance, then a 4 times bigger flame area is necessary if the distance between the flame detector and the fire is doubled.
Weathershield, part noFlame Sensor Test Unit and case, part no The biggest problem is our ignorance; some infrared detectors have an automatic detector window self test, but this self test only monitors the occurrence of water or ice on the detector window.
