  1. An Introduction to FIRE SENTRYC 0 R P O R A T I O N Electro-Optical Fire Detection& Visual Smoke Detection

  2. Company Background • Founded in 1984 • Privately owned • Headquarters in Brea, California, USA • Technology based onMilitary Missile Warning Systems • Industry Leader in Advanced DigitalElectro-Optical Fire Detection • Second Largest Manufacturer ofElectro-Optical Fire Detectors in the World(Frost & Sullivan Marketing Report Published in 2000)

  3. Technical Background • Aerospace Designers • Former Aerospace Production Personnel • Aerospace Design Experience: • Armored Vehicle Early Warning • Aircraft Self-Protection • Countermeasures • AAA Early Warning • Ground & Air-to-Air Missile Early Warning • Submarine Countermeasures

  4. Electro-Optical Fire Detectors Used in many Industries: • Oil & Gas Exploration and Production • Gas Transmission • Petrochemical • Automotive • Semiconductor • Aviation • Explosives, munitions and airbag manufacturing • All Types of Manufacturing

  5. Glossary of Terms • WBIR – Wide Band Infrared(0.7 to 3.5 micrometers) • NIR – Near Band Infrared(0.7 to 1.1 micrometers) • IR – Narrow Band Infrared(Typically 4.3 micrometers) • UV – Ultraviolet(Typically 185 to 260 nanometers) • VIS – Visible Light(400 to 700 nanometers) • FireBusTM(FSC’s proprietary RS-485 Communications Software) • FirePicTM(Pre-Fire Alarm Data stored in Non-Volatile Ram)

  6. Electro-Optical Fire Detectors Theory of Operation

  7. Electro-Optical Fire Detectors Electro-Optical Fire Detectors sense the radiated Electromagnetic Fire energy in the Ultraviolet and Infrared wavelengths.

  8. 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. Electromagnetic Radiation There are (3) phenomena throughwhich energy can be transmitted: 1. Electromagnetic Radiation 2. Conduction 3. Convection Unlike conduction and convection, electromagnetic radiation needs nomaterial medium for transmission.

  10. Electromagnetic Spectrum Fire Sentry Electro-Optical Fire Detectors use all or a combination of these three light spectra to detect a fire

  11. Electro-Optical Fire Detectors Hydrocarbon Fires produce: Water and Carbon Dioxide & Electromagnetic Radiation IR (Heat), UV and VIS Typical combustion of a Hydrocarbon C3H8 + 5O2 = 3CO2 + 4H2O (Propane + Oxygen = Carbon Dioxide + Water) Incomplete combustion produces more Carbon Monoxide (CO)

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