Fire Alarms for Commercial Premises

CIA is BAFE SP203 accredited for design, installation, commissioning & handover, verification and maintenance of fire detection & alarm systems.  We fully understands the complexities surrounding the installation of fire alarms in commercial properties.  This page outlines the Regulatory Reform Order and the British Standards.

Fire Alarms in Business Premises/Commercial Property

The starting point of every commercial fire alarm installation is a Fire Risk Assessment.

The Regulatory Reform (Fire Safety) Order 2005 requires every commercial premises to appoint a ‘responsible person’ who is accountable for producing a fire risk assessment of the property… read our Guide for Responsible Persons.

If a business’s responsible person does not want to do the risk assessment, they can nominate an independent fire risk assessor who will undertake this service for a fee.

CIA cannot, by law, undertake a fire safety risk assessment for a business but our qualified and knowledgeable fire system designers can advise on what should be taken into consideration when preparing it.  We can also help you understand the British Standards, and have a wealth of expertise on the application of the various fire alarm products.

The British Standard is broken down into categories.  Loosely speaking, the categories are split into L systems where the prime aim is to save life, and P systems where the prime aim is the protection of property, and M systems – which are always required within L systems, and sometimes for P systems – for manual operation (call points).

The following explanations are intended as a reference only:

M – A system is designed for life protection and includes manual break glass call points located adjacent to all exits from the property and on each main landing but there is no automatic detection.

P1 – A system designed for the protection of property with automatic fire detection installed throughout the property, including roof voids.

P2 – A system designed for the protection of property with automatic fire detection installed in specified risk areas only.

L1 – A system designed for the protection of life with automatic fire detection located throughout the property, including roof spaces and any roof voids over 800mm associated with the above protected areas.  (Voids less than 800mm are subject to risk assessment.)

L2 – A system designed for the protection of life with automatic fire detection located within the communal escape route(s), all rooms opening onto the escape route(s) and within other specified risk areas, including any roof voids over 800mm associated with the above protected areas.  (Voids less than 800mm are subject to risk assessment.)

L3 – A system designed for the protection of life with automatic fire detection located within the communal escape route(s) and all rooms opening onto the escape route(s), including any roof voids over 800mm associated with the above protected areas.  (Voids less than 800mm subject to risk assessment.)

L4 – A system designed for the protection of life with automatic fire detection located within the communal escape route(s) only, including any roof voids over 800mm associated with the above protected areas.  (Voids less than 800mm are subject to risk assessment.)

Audibility levels – Category L & M systems require sufficient audible warning devices to achieve a minimum audibility level of 65dBA or 5dBA above ambient noise levels in all normally accessible parts of the property. In sleeping risk areas, a sound level of 75dBA is required at each bed head.
