Prior to the invention of Stratos^TM HSSD, ASD systems were reliant on a manufacturer’s recommended settings for different environments. These generic recommendations are an attempt to suit an ASD system to the protected environment. It is a typically a best-effort approach to provide a degree of acceptable protection. Due to this, traditional ASD systems rely heavily on the commissioning engineer’s expertise in fine tuning the system sensitivity to suit a protected environment. Even with all these efforts, ASD systems are typically prone to unwanted alarms from naturally occurring ambient fluctuations within the protected space. The main challenge is in the balancing act of maintaining a high enough sensitivity while at the same time reducing and eliminating unwanted (nuisance) alarms. Automated Monitoring and Adapting to Ambient Fluctuations became the obvious solution to this problem.

To solve the “High Sensitivity and Unwanted Alarms” conundrum, the inventors of Stratos^TM HSSD used a new approach for sensitivity scaling called Relative Scaling. Relative Scaling is a concept that eliminates human guesswork from the equation. Relative Scaling works by means of an Artificial Intelligence that continuously monitors and makes automated adjustments to optimise the ASD’s sensitivity to exactly suit a protected environment. In addition, Relative Scaling is also capable of minimising unwanted alarms due to the A.I.’s decision-making algorithm. For almost 30 years, Stratos^TM HSSD system has been the only Relative Scaling ASD available. Only recently has there been a recognition from the general industry for this unconventional fire detection method, resulting in research into similar technologies by other manufacturers.

Even then, most other brands have only managed to produce an approximation of the Stratos^TM HSSD Relative Scaling capabilities or hybrid Relative-Absolute Scaling products. The secret of the Stratos^TM HSSD success lies in its proprietary Artificial Intelligence called ClassiFire^TM. Stratos^TM HSSD’s Relative Scaling allows it to be deployed within ultra-clean environments as well as dirty and dusty spaces with equal efficacy. In recognition of this revolutionary technology, Airsense Technology Ltd, UK was awarded the Queen’s Award for Technological Achievement in 1999. This was the first time ever the award had been bestowed upon a fire detection product and/or manufacturer.
