- BA BS 5839-1 Category M manual system
- CA BS 5839-6 system, at least Grade D2 Category LD3

Why: Clause 4: a Category L2 system is installed only in defined parts of the building. Its objective is that of an L3 system plus early warning to occupants of rooms in which people sleep and in specified areas of high fire hazard or risk. L1 is installed throughout all areas.
03What type of premises would typically require a Category L1 system?
- AOffices
- BCare homes
