3. Detectors Incorporated (DI) History
• Detectors Incorporated was founded in August 2015.
• DI is collective of partners from the detection industry. Our
team’s shared experience is 100+ years developing,
designing and marketing detection.
• The DI team launched a new disruptive technology which
resolved known issues. The first project took two years, from
concept to launch three product lines.

4. Flame Detection Design Parameters
• False Alarm Immunity (FAI)
• Field of View (FOV)
• Coverage Area
• Speed of Response
• Self Diagnostic

5. False Alarm Immunity (FAI)
• The false alarm immunity is the most critical parameter due to the financial
ramifications - i.e. activation of the extinguishing system and fault in
production.
• False radiation from many environmental or industrial sources can impede
with the fire spectrum which can make it difficult to detect the flame. The
device should not be affected by this environment and at the same time
should have a good sensitivity to fire.
• The type of false sources tested (welding arc, tungsten, halogen lamp, etc.)
• During the time of installation - one must keep in mind false alarm sources
such as modulated infrared source, direct or reflected sunlight or vapors
represents a significant background radiation which can reduce the
detector’s sensitivity.

9. Flame Detection Technology (Past & Present)
• Ultraviolet (UV)
• Ultraviolet detectors (UV) can only react to UV radiation that has a wavelength of less
than 300 nm (a solar blind region).
• Infrared (IR)
• An IR detector is a pyroelectric sensor that is capable of detecting thermal radiation and
is rather sensitive to variations of the received light signal. A tantalum/lithium crystal is
associated with an OP amp or a field effect transistor. An optical filter (a spectral gate)
chooses a specific spectral band or wavelength (2.9 µm, 4.3 µm, 4 to 5 µm…).

17. Conclusion
• Which type of flame detector you chose depend on the following:
• what type of fire (metal fire, flammable liquid fires, etc.)
• where is the environment (outdoor, indoor, industrial, offshore, etc.)
• what is the acceptable response time?
• what is the required overall coverage area?
• The overall functional system:
• Devices location, adjustment of sensitivity and time delay settings.
• Maintenance
• Cleaning the device window - the OptiRadar self-tests indicates a fault or as a preventive measure.
