Fire Alarm Domestic
All fire alarm systems installed should follow the relevant British Standard BS 5839. Guidance given in the BS 5839 code of practice is suggested as the minimum standard to follow for domestic buildings.
BS 5839-6 ‘Fire detection and fire alarm systems for residential buildings. Code of practice for the design, installation and maintenance of fire detection and fire alarm systems in dwellings’ gives guidance and recommendations for all dwellings, including existing.
These British Standards are the current “codes of practice” for installers, architects and designers to follow. They have been put in place as best practice guidelines in order to minimise the loss of life.

The Category of System
What areas should I protect?
The standard states that the level of protection to the occupants needs to be directly related to the fire risk. However it does list three categories of system to describe the level of protection the systems provide. Where and how many alarms are installed will affect how quickly a fire is detected – generally the higher the category of system the higher the level of protection.
LD1 High Protection
- All areas where a fire could start, e.g.
- Hallways
- Landings
- Living Room
- Kitchen
- Bedrooms
- Airing Cupboards
- Meter Cupboards
LD2 Medium Protection
- Escape Routes and high risk areas, such as:
- Hallways
- Landings
- Living Room
- Kitchen
LD3 Minimum Protection
- Escape routes, such as:
- Hallways
- Landings
