The choice of a fire alarm system depends upon many criteria, but specifically the building type and its construction, the purpose of use, and the current legislation. Where new and altered buildings are concerned fire safety is the duty of the owner of the building, but the responsibility for checking that the building regulations have been observed is down to local building control or an approved Inspector from the private sector.

Fire alarm systems all fall within the standards defined in BS5839, either Part1:2017 which is the code of practice for design, installation, commissioning and maintenance of systems in non-domestic premises, and Part 6:2013, which is code of practice for the design, installation, commissioning and maintenance of fire detection and fire alarm systems in primarily for domestic properties. Both of these have several categories/levels, which can cause confusion, especially if you have not had a proper fire risk assessment performed and a suitably qualified person has provided the appropriate guidance.
