Fire Protection Categories

Fire alarm systems are designed with one of three considerations at their core, Category M, Category L and Category P.

Category M systems are manual systems that incorporate no automatic fire detection.

Category L systems are automatic fire detection systems designed for the protection of life; these are normally specified as a result of a fire risk assessment and/or a specific building regulations.

Fire Alarm Systems

Roland Security are specialists in the design, installation of Fire Detection and Fire Alarm systems to assist in the protection of your business and premises.

Business properties required a fire risk assessment and to implement a fire management plan, in many cases, this means the additional need for a fire alarm system.

The Regulatory Reform (Fire Safety) Order 2005 states that all non-domestic properties are required to carry out a fire risk assessment and implement a fire management plan which in most cases means maintenance and service of the fire detection and alarm system.

We can offer a comprehensive service, including design, installation and servicing of high-quality Commercial Fire Detection and Fire Alarm Systems to BS5839-1 2017 standards. These Fire systems provide a complete protection to a wide range of commercial premises.

Our qualified fire system design team can advise you on the latest in new fire detection and fire alarm systems. They can also provide professional advice and recommendations to enhance your existing system and ensure your business complies with all current regulations.


Category L systems

  • L1 Systems installed throughout all areas of the building

  • L2 Systems installed only in defined parts of the building, including all parts necessary to satisfy the recommendations of the code for a Category L3 system. The additional areas protected, over and above those protected in a Category L3 system, are those in which there is either a high likelihood of fire starting or a high risk to life if a fire does start.

  • L3 Systems designed to give 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 due to the presence of fire, smoke or toxic gasses. To satisfy this objective, other than in the case of very short corridors, fire detectors need to be installed in all rooms or areas that open into the escape routes.

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

  • 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 systems).

Category P Systems

Category P systems are automatic fire detection systems intended for the protection of property.

  • P1 Systems installed throughout all areas of the building

  • P2 Systems installed only in defined parts of the building.
