Stratos-HSSD is normally only supplied to customers with existing systems and is not recommended for new installations. For new installations use the Stratos-HSSD 2 or Stratos-Micra. To see Stratos-HSSD 2 click here.

Stratos-HSSD is an air sampling smoke detector. See our Introduction to Air Sampling technical paper for a general overview of smoke detection methods.

AirSense Technology Ltd has a team of specialists with over 175 man years experience in the field of air sampling High Sensitivity Smoke Detection. We drew upon this experience to produce Stratos-HSSD®, which embodies many unique features to maximise performance and increase reliability compared to alternative systems.

Stratos-HSSD embodies innovative features which depart from accepted techniques for detectors which operate at very high sensitivity. Perhaps the most important feature of the system is the adoption of a patented 'artificial intelligence' known as ClassiFire. This controls all aspects of the system operation. ClassiFire ensures that Stratos-HSSD operates at maximum SAFE sensitivity to give warning of problems earlier than previously considered possible.

ClassiFire is the most comprehensive intelligence found in a smoke detection system to date. Not only does it determine the maximum reliable sensitivity for the environment, but is also controls the dust separator monitoring for maximum efficiency.

 

 

The detection principle used in Stratos-HSSD is known as 'forward light scattering' where the laser beam is diffracted by a small angle by smoke particles. This principle not only offers high sensitivity, but sensitivity to a known range of particle sizes.
A patented feature of the system is that compensation is made for any contamination, ensuring a long and trouble free life.

Stratos-HSSD is the only high sensitivity system which is routinely applied to the protection of very dirty and dusty environments. This is achieved by using Laser Dust Discrimination (LDD) with a patented dust management and separator system. These features have greatly extended separator life service intervals. At the other extreme, Stratos-HSSD is capable of providing the very highest levels of sensitivity in environments such as computer and clean rooms. In these applications it is able to sense the very smallest amounts of smoke.

By using the latest semiconductor laser, electronic components and manufacturing techniques enable the Stratos-HSSD system to be supplied and installed with a significantly lower whole-life cost then alternative high sensitivity systems.

Stratos-HSSD® provides three alarm level outputs and a fault output to the fire alarm panel. The interface is an industry standard that many manufacturers provide their own interface cards for connection to their panels. For multi-detector systems, Stratos-HSSD has the option of using unique 'Slave' detectors which are controlled by the 'Master' unit. This offers further significant cost advantages without compromising performance or reliability in any way.

Stratos-HSSD is supplied with comprehensive diagnostic facilities as standard. By simply plugging a PC into the serial port you can display diagnostic menus which give the capability of fault finding down to the individual component level. ClassiFire may be viewed working in real time. You can also view a detailed chart recorder of historical smoke levels showing date, time and alarm thresholds.
