Fire
Detection

L1–L5 categories

Category L5 fire alarm systems are designed for buildings that have a particular risk identified which warrants some special attention. For example, if there is an area of high risk, which is considered worthy of having some automatic detection, but a manual system is also needed, then this will be termed as L5/M.

Category L4 provides detection within the escape routes only, whereas L3 not only covers these areas but all rooms leading onto the escape route. The reasoning behind this is to alert people of the danger prior to the corridor becoming ‘smoke logged’ so people can escape safely.

Category L2 is a further enhancement of protection with all the areas covered by an L3 category as well as high-risk areas such as boiler rooms etc.

Category L1 provides protection throughout the building.
