A single Smoke Alarm will give some protection if it is properly installed, but most homes will require
two or more to ensure that a reliable early warning is given. For recommended protection you should
put individual Smoke Alarms in all rooms where fire is most likely to break out (apart from the kitchen
and bathroom).
BS 5839-Part 6:2013 and IS 3218:2013 give guidance on:
- how many Alarms to install
- what type of Alarm to use
- where to position Alarms
The above points will depend on the type of dwelling to be protected and the level of fire risk.
Fire Risk Assessment
The ‘Grade’ and ‘Category’ of system that should be installed depends on the fire risk. It is therefore
recommended that a Fire Risk Assessment is undertaken. The Risk Assessment would be based on a
combination of probabilities:
- fire occurring
- injury or death to occupant
- system operating correctly with a fire
- early detection and warning to occupants in the event of a fire.
The greater the risks, the more comprehensive and reliable systems needs to be.
LD (Life protection in Dwellings) Systems define the level of fire protection required for households,
depending on the fire risk and regulations. Ei Electronics recommends that an LD1 system be installed
for optimum protection.
