Our Voltimum Experts answer your questions on a daily basis in our Technical Expertise area. This one, regarding redundant fire alarm systems and standards, is answered by the ECA:
Answer: BS 5839 Part 1: Code of practice for system design, installation, commissioning and maintenance, was first published as a British Standard in January 1980. Over the years it has been revised and amended as and when new installation practices and new technology become more relevant. Consulting the older withdrawn version of the standard will highlight changes that might be installed, but not up to current standard.
With regard to redundant fire alarm systems, all new installation work will need to be carried out to the current standard, and any deviations because of the standard moving on would have to rectified - and the installation brought up to current standards.
