BS5839 - Part 1 - Fire Detection & Alarm Systems for Buildings

This presentation gives an overview of the 2017 update & changes to British Standard BS5839 Fire Detection & Alarm Systems for Buildings, Part 1 Code of practice for design, installation, commissioning and maintenance of systems in non-domestic premises. It assumes a knowledge of the previous BS5839-1 standards & concentrates on what has changed in the 2017 revision.

This presentation describes how certain sound pressures and frequencies can cause vibration and damage to Hard Disk Drives (HDD). The sound pressure and frequency from a gas extinguishing discharge falls within this range that is known to cause damage to HDD’s. Research has been carried out into this phenomenon and manufacturers have come up with different solutions to the problem. The various studies and different solutions are presented along with other measures that can be taken to mitigate noise damage in a datacentre. Methods of calculating predicted noise levels and practical solutions for new and existing installations are discussed.

This presentation gives a brief overview of sprinkler systems, various types of gas extinguishing systems and water mist systems. As sprinklers and gas extinguishing systems are widely known, more time in spent on water mist and explaining its different uses and applications. There is a specific section on data centre protection. The presentation compares the different technologies and the pros and cons of each system and their applications.
