Industrial & Commercial Fire Alarms & Suppression Systems

There are eight individual fire alarm categories defined by the BS 5839 code, the British Standard for fire alarm installation and the governmental code of practice. These categories fall into three main system types: manual, life protection, and property protection. The type of fire alarm system your business requires depends on:

• The type of premises
• The contents within your business
• The nature of your business
• The level of risk

‍

A fire risk assessment, which can be carried out by the fire safety experts at Aberdeen Alarm Company, is essential to determine the appropriate fire alarm category for your premises. Our team can assess your site to ensure that the system installed provides optimal protection for life, property, and compliance with regulations.

Details on Life Protection Systems

Category L Fire Alarm Systems – Life Protection

Life protection systems are divided into five categories:

• L1: Automatic Fire Detection (AFD) installed throughout all areas of the building.
• L2: AFD as defined in L3, with additional detection in high-risk areas like kitchens, boiler rooms, or storerooms.
• L3: Smoke detection on escape routes and in rooms opening onto escape routes.
• L4: AFD installed only within escape routes.
• L5: Targeted detection in specific high-risk areas, often designated as L5/M when combined with a manual system.

Category M Fire Alarm Systems

A BS5839 Category M Fire Alarm System is a manual operation only system which has call points on all exits as well as corridors where persons are not expected to walk any more than 45m to operate one.

All categories of life protection will have a type M system installed.
