ASD Data Center with Airsense Prsentation

ASD

1. Detection for challenging environments

2. Challenging applications

3. What is ASD? Aspirating smoke detection (ASD) active fire protection system  Central detection unit draws air through network of pipes to detect smoke. Sampling chamber detects presence of smoke particles in air by detecting light scattered in chamber.  ASD detects smoke before visible to naked eye.  In most cases, detector requires fan to draw air from protected area through network of pipes 3

4. Where standard detection is not enough Aircraft hangars Airport terminals  Atria  Cable tunnels  Ceiling voids, raised floors  Cleanrooms  Coal conveyers  Computer cabinets  Computer rooms  Correction facilities  Data processing centers  Engine rooms  Escalators  Flour mills Food preparation areas Freezer warehouses  Heritage buildings  High-end residential  Hospitals  Hotel lobbies  Metro tunnels  Museums  Paper mills  Record storage facilities  Recycling centers  Semiconductor fabrication  Telecommunications facilities  Textile areas  Warehouses Distribution centers 4

5. Why ASD? Overcomes shortcomings of conventional smoke detectors.  Air samples captured and filtered to only allow smoke particles Overcomes issues such as stratification or low/diluted smoke transport.  Alert raised when ability to detect smoke is compromised  Incorporates more than one level of alarm.  Allows very early warning of event, even at smouldering stage .   Alarm sensitivities configurable from thousands of times more sensitive than conventional detector, to much less sensitive.  Detector can be remote from protected area Eases access and maintenance 5

6. Challenging Environments 6 Atria Hard to access areas High Airflow Areas Clean Rooms Harsh Environments Power Generatoin Cold Environments Covert detection Storage, Large open areas & Large volume buildings

8. High airflow areas - Challenges 8 Challenges How to keep operations running 24/7 Unexpected problems can have serious consequences Causes of fire diverse, e.g. rodents biting through wires, lightning strikes, overheating, electrical faults Datacentres have many fuel sources – plastics, circuit boards, conductor insulation Datacentres and server rooms can have very high air flows Smoke moved away from point detectors and diluted Difficult to reach smoke levels required to generate alarm In many datacentres, there is a requirement for below false floor detection Why  Modulaser ? Primary sampling of HVAC air can provide very early warning in business-critical applications Cumulative effect of multiple sampling points and very high sensitivity of  ModuLaser  makes effective secondary detection possible  Under floor detection is simple to install due to ability to invert detector module

9. High airflow areas - pain points 9 Pain Points Fire second-leading cause of failure in datacentres (after power issues) Risk increasing as greater power densities (20-plus kW per rack) are housed in more confined spaces. Data centre market predicted to grow at 20% per year in 2022 Cost of downtime very expensive, both monetary and reputational Damage to infrastructure and data recovery can run into tens of millions of pounds

10. Key technical challenges & solutions – High airflow areas Challenge Solution How to keep operations running 24/7 ModuLaser has remote fault notification, meaning that an engineer is notified as soon as a fault occurs or as soon as a low level alarm is triggered Datacentres have many fuel sources – plastics, circuit boards, conductor insulation As Modulaser can provide early warning of smoke and smouldering, and immediately notify an engineer, reducing risk from smouldering flammables Datacentres and server rooms can have very high air flows Because Modulaser actively draws air into the detector, and is very sensitive to smoke, the detector is less affected by high airflows Common requirement for below false floor detection Modulaser pipework can be run anywhere that normal pipework can be installed, including behind false ceilings and floors 10

11. DATACENTRE design guidelines – ASD installation 11

12. Datacentre design guidelines - Return air grill  Full air intake grille should be adequately covered by number of sampling points.  Each sample point shall have maximum coverage of 0.4 m² of air grille. Single pipe should not cover multiple AHU  Pipe should be positioned in main air-stream with sample holes at around 20–45 degrees from incoming air, in area of neutral pressure.  For large airflows into grille (e.g. >4m/s) special arrangements may be necessary, such as positioning pipe away from grille using stand-off brackets. End cap should be closed 12

13. Datacentre design guidelines – return air grill Maintenance access to air-handling unit should not be restricted by sampling pipe. Convenient removal of pipe should be accommodated 13 Internal mounting of pipe sometimes desirable but requires special consideration due to internal operation of air-handling unit (dampers and louvers) and increased negative pressure 

14. Datacentre design guidelines – in cabinet detection 14 Pipe work and air sampling points are arranged to monitor specific pieces of equipment But differs from Localized systems due to protected volume being small, self contained risk and challenges associated with cooling of critical electronic and electrical equipment. Generally considered that enhanced Class B or very high sensitivity Class A systems are appropriate
