Introduction Contacts THE INTELLIGENT SOLUTION FOR HIGH SENSITIVITY ASPIRATING SMOKE DETECTION SM 10:28:06 PM Applications Technology Overview Questions & Answers Detection Chamber Light Receiver Smoke particles entering the chamber will be illuminated by the laser And Light will be scattered onto the reflective plane, re- focussed onto the light receiver The quantity of light scattered increases with greater quantities of smoke particulate present Technology Overview

10. Introduction Contacts THE INTELLIGENT SOLUTION FOR HIGH SENSITIVITY ASPIRATING SMOKE DETECTION SM 10:28:06 PM Applications Technology Overview Questions & Answers Fixed Vs Relative Sensitivity  The unique technology employed in Stratos ® Aspirating Smoke Detection Systems uses relative sensitivity to establish appropriate alarm thresholds.  The sensitivity is determined by the ambient smoke level of the protected area.  All other systems have their sensitivity (the amount of smoke required to produce an alarm) fixed during manufacture or during commissioning. Why is this a problem? Sensitivity settings are arbitrarily set and often times misapplied Must be manually altered, and are constantly “out of date” Filter loading or optic contamination diminishes smoke level reaching or being processed by the detector Sensitivity to a fire varies with changing ambient conditions Technology Overview

11. Introduction Contacts THE INTELLIGENT SOLUTION FOR HIGH SENSITIVITY ASPIRATING SMOKE DETECTION SM 10:28:06 PM Applications Technology Overview Questions & Answers Fixed Sensitivity Detectors 0 to 2 Weeks1 Month1 Year Using historical data or pre- designated sensitivity set points, the installer selects FIXED sensitivity set points typically above the highest smoke density the detector has registered. These set points will REMAIN at that level until manually altered. The TRUE sensitivity (the difference between ambient and alarm levels) will vary because the alarm point is fixed. As normal activity changes within the environment, the detector is prone to false alarms if the ambient level ever approaches or rises higher than the FIXED sensitivity set points As filter loading occurs or the activity within the environment changes, a trend of reducing ambient smoke level will result in the detector becoming less and less sensitive!

15. Introduction Contacts THE INTELLIGENT SOLUTION FOR HIGH SENSITIVITY ASPIRATING SMOKE DETECTION SM 10:28:06 PM Applications Technology Overview Questions & Answers Applications With the advent of “next generation” Aspirating Smoke Detection Systems which feature a wide sensitivity range and advanced artificial intelligence features, such as ClassiFire, reliable very early warning smoke detection is now possible in a wide range of applications.  Where very early warning detection is required  Where high air flow is present  Where the environment is hostile (very cold, very hot, wet or dusty, strong RF fields or contaminated)  Where detection is to be concealed for aesthetic or covert considerations  Where there are areas subject to smoke stratification  Where access for maintenance is impractical or impossible  Where reliable detection is required for suppression release Applications

16. Introduction Contacts THE INTELLIGENT SOLUTION FOR HIGH SENSITIVITY ASPIRATING SMOKE DETECTION SM 10:28:06 PM Applications Technology Overview Questions & Answers Hostile Environments  By nature of the system, an aspirating smoke detection system, such as Stratos, has no need to be located within the area to be protected, as the air is transported to the detector(s) via sampling pipes. This means ASD can often be used in areas of extreme heat, cold, humidity, high levels of RF interference or in contaminated areas.  The Stratos range of detectors incorporate Laser Dust Discrimination (LDD™). This means that it is possible to provide highly effective smoke detection in dusty hostile environments with minimum risk of false alarms Textile areas Power Generation Plants Cold & Frozen Storages Paper mills / tissue production Flour mills Wood recycling Recycling Centers Metro Tunnels Cable tunnels Coal conveyers MRI rooms Applications
