Fire alarm systems FAQs
What are the different types of fire alarm systems?
What are L1, L2 and L3 fire alarm systems?
L1, L2 and L3 refer to categories of life protection fire alarm systems defined within BS 5839-1. L1 systems provide automatic fire detection throughout all areas of a building for the highest level of life protection. L2 systems provide detection on escape routes and in specified high-risk areas. L3 systems provide detection on escape routes and in rooms opening directly onto those routes.
What are the legal requirements for fire alarms in the UK?
The Regulatory Reform (Fire Safety) Order 2005 requires responsible persons to implement suitable fire detection and warning systems where necessary to protect occupants. Fire alarm systems should be designed, installed, tested and maintained in accordance with relevant British Standards, including BS 5839.
