HOW MANY ALARMS TO INSTALL - CATEGORIES & GRADES - The advice here follows the guidance in British Standard BS 5839-Part 6: 2004 in general (for further information see the BS standard itself). The main reason for fitting Smoke & Heat Alarms in dwellings is to ensure that when there is a fire, sufficient early warning is given so that everybody can escape safely. This means that the fire alarms should ideally be located near all potential sources of fires and that the alarm should be heard throughout the house – particularly in the bedrooms. It is also important that nuisance/false alarms are minimised to ensure the units are not disabled or ignored. The BS standard gives 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. The risk assessment is 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 are needed. 2.1 Categories of System There are three Categories of LD systems for Life protection in Dwellings that can be installed, depending on the fire risk and regulations.
