Understanding Electro-Optical Flame Detectors
-
Electro-Optical Flame Detectors Respond to:
- Ultraviolet (UV) energy
- Visible light (VIS)
- Infrared radiant energy (IR)
Modern electro-optical flame detectors use the combination of these three light spectra to detect a fire. They detect electro-optical radiant energy from the fire at the speed of light. Since the detectors do not rely upon heat or smoke they can detect a fire in its early stages. Also because it is a line-of-sight/cone-of-vision product, the detectors can cover a large area and do not have to be located directly at the fire event to accurately alarm.
Old Technology
Most competitors use single band IR at 4.3 microns. These detectors use narrow band interference filters looking for a CO2 "spike". This spike in a fire is unpredictable as the emission line is narrow and difficult to discriminate from interferences (sun, flares, welding, etc.). Some competitors combine narrow band IR with UV which results in less false alarms yet require "flicker" amplifiers to discriminate interference. This type of technology is antiquated and relies on technology developed during WWII.
Our Advanced Technology
Our flame detection technology uses Wide Band Infrared sensors that respond to IR between 0.7 & 3.5 microns and detect over 88% of the radiant energy generated by a fire. This technology enables detection of all types of fires - both Hydrocarbon and non-Hydrocarbon. Our technology does not use optical interference filters to discriminate interferences. The advanced technology is fast acting using a "Quantum" effect sensor as used in many current military applications. And our technology easily detects a small fire and tracks it as it grows and/or gets hotter.

Disadvantages of Old Technology:
- Will only respond to hydrocarbon fires
- CO2 "spike" is unpredictable
- Real world fires have incomplete combustion producing more CO and less CO2
- Narrow band IR sensors detect less than 1% of radiant IR energy from a fire
- Electromagnetic Radiation is energy waves produced by the oscillation or acceleration of an electric charge.
- The Sun, Earth, and other bodies radiate electromagnetic varying wavelengths.
- All Electromagnetic energy passes through space at the speed of light in the form of sinusoidal waves.
- Electromagnetic Radiation can be arranged in a spectrum that extends from waves of extremely high frequencies and short wavelengths to extremely low frequency and long wavelengths.
