11. HSSD Market
Aspirating HSSD has become widely accepted as a reliable smoke detection method
HSSD is now standard practice in Electronic Data Processing (EDP) environments, telecommunications suites and computer rooms
HSSD has become a viable alternative to other forms of detection in areas previously not considered such as warehouses, cold stores, production areas, shopping malls and heritage buildings
HSSD is often used when other forms of detection prove ineffective or difficult to maintain

12. HSSD Market
Design engineers are identifying more areas where aspirating HSSD will provide the best solution to an assessed risk
On all new projects & retrofits there is scope to include HSSD & provide the end user with an improved detection solution
HSSD can often be installed at comparable or at lower cost than other forms of detection

13. Why Hart Aspirating Smoke Detection?
Earliest detection to enable business continuity
Extra time is required for safe evacuation
Unnecessary suppression release must be avoided
Smoke is difficult to detect
Environmentally challenging areas
Aesthetics & concealed detection are important
Maintenance access is limited

14. Earliest Detection to Enable Business Continuity
Critical processes that cannot incur any business
disruption
Telecommunications facilities
Computer rooms
Banking operations
Production facilities
Internet Service Providers

15. Extra Time is Required for Controlled Evacuation
Environments where rapid exit can be impeded
Underground Stations
Theatres
Public buildings
Airports

16. Smoke is Difficult to Detect
Environments with high ceilings, high air flows or
vast open areas provide unique characteristics
Clean rooms
Warehouses
Aircraft hangars
Computer rooms
Atria

17. Unnecessary Suppression Release can be Avoided
Early warning gives time to investigate to avoid
unnecessary suppression release
Telecommunication facilities
EDP facilities
Computer rooms
Electrical sub-stations

18. Environmentally Challenging Areas
Aggressive environments with high levels of
pollution or extreme temperature conditions can be
protected reliably with acceptable maintenance levels
Cold Stores
Production areas
Paper mills
Underground tunnels
Mines

19. Aesthetics are Important & Replacement Impossible
Interiors that must not be spoilt by unsightly conventional
detectors - Hart XL can be installed unobtrusively
Cathedrals
Stately Homes
Museums
Art Galleries

20. Maintenance Access is Limited
Hart XL can be located at an accessible location while
the sampling pipework makes its way to the restricted area
Warehouses
Production machinery
Prisons
Restricted areas
EMC Controlled areas
Hospitals
