  1. Detector Technologies Ltd

  2. Detector Technologies Ltd • D-Tec was created from two companies, Intelligent Security and AD Holdings (Dedicated Micros) with the sole purpose to further market and develop the technology of detecting fires through the use of CCTV cameras • The technology foundation for Video Smoke Detection was created back in 1996 and the product is continually being refined and enhanced. • From being the pioneers of Video Smoke Detection we have continued to be the World market leaders with continual design and development • D-Tec is a small ‘High Tech’company yet international with distribution networks in Australasia, USA, Africa, Middle and Far East as well as Europe

  3. Itinerary • Factors affecting fire detection • Background to the Nature of Fire and how it develops • Cameras and Lens calculation • Positioning of cameras • Architecture of VSD and FireVu • Benefits of VSD & FireVu over conventional fire detection • Typical Applications • Regions of operation • Latest VSD projects • Approvals and Awards • Future developments

  4. Lets begin ‘Video Smoke Detection’ first appeared on Tomorrow's World programme back in 1997.

  5. Factors Affecting Fire Detection • Detection Type • Room Height • Thermal Barriers • Area of Coverage • Internal/External • Airflow Rate • Access • Ex / Toxic Areas • Acceptability of False Alarms • Alarm Management • Remote Signalling

  6. Fire Development

  7. Smoke/Heat Movement SD Thermal Barrier Flame 20m+ Beam 25m Smoke 10.5m Heat 6m

  8. VSD Area Of Detection Conventional Area Of Detection T H E R M A L B A R R I E R Smoke Cools & Reaches Thermal Barrier Smoke Falls Smoke Falls Smoke Rises Fire Starts

  9. Three Dimensional Thinking • Camera can detect anywhere in the field of view • Lens designates the viewing area

  10. Lens Calculation Methodology • The web makes this task simple • The wider angle the lens the smaller objects • appear in the distance

  11. Images demonstrate different camera lenses • The wider the lens angle the smaller objects appear in the distance

  12. Positioning Cameras Effectively

  13. System Architecture Multiplexer Monitor

  14. System Architecture - FireVu IP Cloud

  15. Benefits of VSD over Conventional Fire Detection • Detection at Source • Visual Verification • Large Area of Detection • Zoning • Ability to “Look” in • Use of Existing Cameras • DETECTS WHERE NOTHING ELSE IS SUITABLE

  16. Benefits of FireVu • Remote monitoring • Visual Memory File • Pre and post alarm video clips • On line diagnostics • On line maintenance / testing • Software Based System • System data management • DETECTS WHERE NOTHING ELSE IS SUITABLE

  17. Typical Applications • High Value Areas • Telecommunications • Production areas • Aircraft Hangers • Shopping Centres • Transportation • External • Historic Buildings • Power Generation Halls • Large Open Areas • Warehouses • Atria • Tunnels • Cold-stores

  18. Regions of Operation

  19. Latest VSD Projects • Genoa – Ventimiglia Road Tunnels (Italy) • QANTAS aircraft hangers (Australia) • Shah Diniz Oil Refinery (Azerbaijan) • London Underground (U.K.) • Ford & Nissan Car Manufacturing Plants • Airbus Hangers (U.A.E. & Oman) • Phosphorous Plant (Australia) • US Navy • Airbus & Boeing On-board aircraft (Germany & U.S.A.) • Network Rail - Euston Station • Swiss-Re Head Office

  20. Visy Recycling Plants - Australia

  21. Collaroo Coal Power Station - Australia

  22. Check Out the Air Filters on That !

  23. Asgard Platform North Sea - Statoil

  24. Stratford Market Depot London Underground

  25. Imperia Test Tunnel

  26. Boeing Construction Hanger Seattle

  27. Approvals & Awards

  28. Future Developments • Flame • Central Station • Pan Tilt Zoom (PTZ) • Fish-Eye Lens • 360° • Web Enabled Camera • Gas

  29. Summary • Offers many advantages over and above other detection devices • Offers detection in environments considered impractical or impossible • Shares CCTV Systems thus can offer cost savings. • Flexibility within the software to allow ‘engineered solution’ and ultimately reduce spurious alarm activations.
