Committed to Life Safety

Fire poses a very real threat to today’s businesses. Of course the most important assets to protect are the lives of the buildings occupants. After this, fire damage to the building and its contents can cause lengthy interruption to normal business activity. As a result, many businesses lose significant revenue following a fire and many are forced out of business completely.

Automatic fire detection and alarm systems play a fundamental part in protecting the people and assets that are most important to you and your business. Realising that every building has its own unique challenges, our supplier's systems are flexible enough to provide solutions to ensure any building, whatever its size or function enjoys the best in fire protection to meet any unique needs.

Whether in a data centre, historic building, factory or office, our suppliers have a tried, tested and trusted solution designed to protect the people and assets that are most important to you.

Introduction

Fire detection and fire alarm systems may be installed in buildings to satisfy one, or both, of two principal objectives, namely protection of life and protection of property. The objectives may differ in time or place. Other possible objectives exist, such as protection against business interruption and protection of the environment; these are likely to be satisfied by the recommendations in this standard for protection of property.
Because of the great variety of applications for systems covered by this part of BS 5839, systems are divided into a number of different Categories, as described in 5.1.2, 5.1.3 and 5.1.4.

Category M Systems

Category M systems are manual systems and, therefore, incorporate no automatic fire detectors.

Category L Systems

Category L systems are automatic fire detection and fire alarm systems intended for the protection of life. They are further subdivided into:

Category L1: systems installed throughout all areas of the building.

The objective of a Category L1 system is to offer the earliest possible warning of fire, so as to achieve the longest available time for escape;

Category L2: systems installed only in defined parts of the building.

A Category L2 system ought to include the coverage necessary to satisfy the recommendations of this standard for a Category L3 system; the objective of a Category L2 system is identical to that of a Category L3 system, with the additional objective of affording early warning of fire in specified areas of high fire hazard level and/or high fire risk;

Category L3: systems designed to give a warning of fire at an early enough stage to enable all occupants, other than possibly those in the room of fire origin, to escape safely, before the escape routes are impassable owing to the presence of fire, smoke or toxic gases;

NOTE To achieve the above objective it will normally be necessary to install detectors in rooms which open onto an escape route (see 8.2).

Category L4: systems installed within those parts of the escape routes comprising circulation areas and circulation spaces, such as corridors and stairways.

The objective of a Category L4 system is to enhance the safety of occupants by providing warning of smoke within escape routes;

NOTE The installation of detectors in additional areas is not precluded, and the system could then still be regarded as a Category L4 system.

Category L5: systems in which the protected area(s) and/or the location of detectors is designed to satisfy a specific fire safety objective (other than that of a Category L1, L2, L3 or L4 system).

Often, the design is based on a localized need for fire detection in only part of a building. Protection might be provided to compensate for some departure from normal guidance elsewhere or as a part of the operating system for a fire protection system. Such a system could be as simple as one that incorporates a single automatic fire detector in one room (in which outbreak of fire would create undue risk to occupants, either in the room or elsewhere in the building), but the system could comprise comprehensive detection throughout large areas of a building in which, for example, structural fire resistance is less than that normally specified for buildings of that type.

Category P systems

Category P systems are automatic fire detection and fire alarm systems intended for the protection of property. They are further subdivided into:

Category P1: systems installed throughout all areas of the building.

The objective of a Category P1 system is to offer the earliest possible warning of fire so as to minimize the time between ignition and the arrival of firefighters;

Category P2: systems installed only in defined parts of the building.

The objective of a Category P2 system is to provide early warning of fire in areas of high fire hazard level, or areas in which the risk to property or business continuity from fire is high.

NOTE The defined parts of the building may be as few as one or more rooms, or as extensive as, for example, complete floors of the building.
