7 FIRE SENTRY CORPORATION © 2001 Electro-Optical Fire Detectors sense the radiated Electromagnetic Fire energy in the Ultraviolet and Infrared wavelengths. Electro-Optical Fire Detectors

8 FIRE SENTRY CORPORATION © 2001 Electromagnetic Radiation  Electromagnetic Radiation is energy waves produced by the oscillation or acceleration of an electric charge.  Electromagnetic Radiation can be arranged in a spectrum that extends from waves of extremely high frequency and short wavelength to extremely low frequency and long wavelength.  Visible Light is only a small part of Electromagnetic spectrum.

9 FIRE SENTRY CORPORATION © 2001 There are (3) phenomena through which energy can be transmitted: 1.Electromagnetic Radiation 2.Conduction 3.Convection Unlike conduction and convection, electromagnetic radiation needs no material medium for transmission. Electromagnetic Radiation

10 FIRE SENTRY CORPORATION © 2001 Electromagnetic Spectrum Fire Sentry Electro- Optical Fire Detectors use all or a combination of these three light spectra to detect a fire

11 FIRE SENTRY CORPORATION © 2001 Hydrocarbon Fires produce: Water and Carbon Dioxide & Electromagnetic Radiation IR (Heat), UV and VIS Typical combustion of a Hydrocarbon C 3 H 8 + 5O 2 = 3CO 2 + 4H 2 O (Propane + Oxygen = Carbon Dioxide + Water) Incomplete combustion produces more Carbon Monoxide (CO) Electro-Optical Fire Detectors

12 FIRE SENTRY CORPORATION © 2001 Advantages of Electro-Optical Fire Detectors: s Fast - detects Electromagnetic Radiant Energy from the fire (Moves at the Speed of Light 186,000 mps/300,000 kps) s Fast - detects fire in the early stages s Area Coverage, not a point detector. Does not have to be located directly at the fire event Electro-Optical Fire Detectors
