BS5839-1,2017 Update – What has Changed (Fire Detection & Alarm Systems for Buildings – design, installation, commissioning and maintenance)

This presentation gives an overview of the British Standard BS5839 Fire Detection & Alarm Systems for Buildings Part 1 Code of Practice for system design and installation and servicing. It describes the different categories of fire detection and alarm systems, the design and application of their component parts – and their differences, the requirements of installation and commissioning and handover, and the maintenance and user-requirements after installation. It also covers the use of competent companies and different accreditation schemes.

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.
