Here Ian Ballinger, Certification Manager for FireAngel, outlines the key updates professionals should be aware of in order to ensure constant compliance when specifying, installing and maintaining fire detection systems in domestic properties.
Covering the implementation of fire precautions in domestic premises, including HMOs and sheltered housing, throughout both the dwelling units and common areas, the Standard is applicable to both new build and materially altered dwellings in conjunction with regional building regulations as well as existing properties.
The recommendations can be applied to the fire detection components of combined domestic fire and intruder alarm systems, or fire and social alarm systems. New recommendations have been added for fire detection in supported housing in particular, whilst revised guidance on the installation of communal fire alarm systems in purpose-built blocks of flats has also been introduced.
The Standard has also been updated to reflect the updates made to Part 1 in , which addresses non-domestic premises, combined with any other updates made to other Standards since the last full revision. This applies to architects, building professionals, installers and enforcing authorities. Grade C has been revised and its recommendations expanded. Grade C Separate detectors and sounders that are mains powered with back-up power supply and central control equipment. Grades B and E are no longer defined in BS Professionals should adhere to the above grades when designing, constructing and managing fire detection and fire alarm systems in domestic properties.
They should also be aware of the revisions made to Table 1 of The Standard, which outlines the minimum grade and category of system that should be installed to provide protection of life in typical premises. The updates have been made to reflect current living conditions. In conjunction with Table 1, a new table has also been created, which outlines the recommended testing and servicing by grade to prevent the blocking or delaying of fire alarm signals transmitted via social alarm systems in sheltered housing to an alarm receiving centre.
Categories for fire detection and fire alarm systems as per BS : With regard to categories, the standard of protection in sheltered housing flats has been increased from Category LD2 to Category LD1, positioning it as a higher potential risk. To meet LD1 requirements, the installation of a fire detection system is required throughout the premises - this includes all rooms and circulation areas that form part of the escape routes except toilets, bathrooms and shower rooms.
The three categories for fire detection and fire alarm systems are listed below and outline where fire detection systems should be installed: LD1 Maximum Protection Escape routes, high risk rooms plus all areas where a fire might start Escape routes, high risk rooms plus all areas where a fire might start Category LD1: The highest level of protection of all occupants who might occupy the dwelling over the lifetime of the fire detection and fire alarm system.
A system installed throughout the premises, incorporating detectors in all circulation areas that form part of the escape routes from the premises, and in all rooms and areas, other than those with negligible sources of ignition, such as toilets, bathrooms and shower rooms.
