What is HART High SensitivitySmoke Detection (HSSD)?
• Aspirating detection system
• Fan draws air through sampling pipework system
• Capable of detecting smoke concentration as low as 0.0025% obscuration per metre down to 1%
• Display Control Unit provides indications and controls

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
![Page 11: High Sensitivity Smoke Detection Kelvin Miller](https://reader034.vdocuments.mx/reader034/viewer/2022051401/56649f145503460f94c294ad/html5/thumbnails/11.jpg)
12
• 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

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
![Page 13: High Sensitivity Smoke Detection Kelvin Miller](https://reader034.vdocuments.mx/reader034/viewer/2022051401/56649f145503460f94c294ad/html5/thumbnails/13.jpg)
14
