Fire Alarm categories explained:

Fire alarm systems are categorized according to BS5839:Pt1 and BS5839:Pt6 standards to ensure appropriate safety measures are in place. The categories help determine the level of protection required for different types of buildings and situations.

Each category plays a vital role in ensuring the safety and security of buildings and their occupants. It is important to assess the specific requirements of a building and choose the appropriate fire alarm category accordingly to ensure that your property is adequately protected. By seeking guidance from professionals, such as your insurance provider or a risk assessor, you can make an informed decision on the most suitable type of fire alarm for your premises. Remember, having the correct category of fire alarm can make a significant difference in safeguarding your property and the people within it. Don’t hesitate to reach out for expert advice to ensure the safety and security of your space.

For commercial properties, compliance with BS5839: Part 1 is crucial to ensure the safety and well-being of occupants and visitors. This standard provides guidelines for the design, installation, commissioning, and maintenance of fire detection and alarm systems in non-domestic buildings. By adhering to the requirements outlined in BS5839: Part 1, businesses can significantly reduce the risk of fire-related incidents and protect both property and lives. Regular testing and maintenance of fire detection systems are essential to guarantee their effectiveness in case of an emergency. Investing in proper fire safety measures not only safeguards the premises but also demonstrates a commitment to prioritizing the safety of everyone within the commercial property.

For Domestic properties, compliance with BS5839: Part 6 is essential to ensure the safety of occupants in case of a fire emergency. This standard provides guidance on the design, installation, and maintenance of fire detection and fire alarm systems in domestic buildings. By following the regulations outlined in BS5839: Part 6, homeowners can create a safe environment that can alert residents promptly in the event of a fire, allowing them to evacuate the premises quickly and efficiently. It is important to regularly test and maintain these systems to ensure they are functioning correctly and provide the necessary protection. By prioritizing compliance with BS5839: Part 6, homeowners can significantly enhance the fire safety measures in their properties and protect the well-being of their loved ones.

Understanding the level of detection for commercial premises:

Category L1 – Maximum Life Protection Automated Fire Alarm System

  • L1 systems are the most comprehensive, with multiple detectors covering all areas where fires could potentially start in a building, including larger cupboards, roof spaces, and voids.
  • The primary aim is to provide early warnings to occupants for life preservation, covering all building areas except for small cupboards and lobbies.

Category L2 – Additional Life Protection Automated Fire Alarm System

  •  L2 systems offer advanced warning to building occupants about fires in other rooms. By having detection devices in escape routes, rooms leading onto escape routes and specialized areas such as kitchens and boiler rooms.
  • Typically, fire and smoke alarms are placed in high-risk rooms and along escape routes leading to fire exits, focusing on areas like kitchens in small and medium-sized premises.

Category L3 – Standard Life Protection Automated Fire Alarm System

  • L3 systems, known as standard life protection systems, have alarms along all escape routes and rooms leading onto escape routes from the interior of the premises to fire exits.
  • The goal is to ensure that all occupants receive adequate warning to exit the building before smoke, fire, or toxic fumes hinder their escape, without requiring alarms near high-risk ignition sources.

Category L4 – Modest Life Protection Automated Fire Alarm System

  • L4 systems only position detectors in escape routes like hallways, stairwells, and corresponding circulation areas, not in individual rooms.
  • These systems suit low-risk environments where quick evacuation is possible, such as ground floor offices using L4 alarms in entryways.

Category L5 – Localised Life Protection Automated Fire Alarm System

  • L5 alarms are specialized systems addressing fire hazards in high-risk areas, like factories installing extra fire detection equipment in welding zones.
  • Businesses can combine L4 systems across their premises with L5 standards in specific high-risk rooms, such as installing L5 equipment in server rooms while maintaining L4 elsewhere.

Category P1 – Maximum Property Protection Automated Fire Alarm System

  • P1 systems focus on protecting property from fire, often implemented in operationally critical areas like computer rooms.
  • The goal is to swiftly detect fires and prevent significant damage, aiding in protecting lives and critical business assets, serving as a form of business continuity planning.

Category P2 – Minimum Property Protection Automated Fire Alarm System

  • P2 systems deploy fire and smoke detectors only in high-risk areas rather than across the entire premises.
  • These cost-efficient systems optimize funds usage but may fall short if fires occur unexpectedly.

Understanding the level of detection for domestic premises:

Category LD1 – Maximum Life Protection Automated Fire Alarm System

  • LD1 systems the highest level of protection for all occupants by including detectors in escape routes and all rooms except those with minimal ignition sources like toilets and bathrooms.
  • Their primary objective is to give early warnings to occupants for life preservation

Category LD2 – Additional Life Protection Automated Fire Alarm System

  • LD2 systems integrates detectors in escape routes and all circulation areas connected to an escape routes within the premises, as well as in designated rooms or areas that pose a significant fire risk to occupants, such as kitchens and main living spaces.
  • These systems typically place fire and smoke alarms in high-risk rooms and along escape routes leading to fire exits, focusing on areas such as kitchens in small and medium-sized premises.

Category LD3 – Standard Life Protection Automated Fire Alarm System

  • LD3 systems an integrated system that includes detectors in all escape routes from the domestic premises.
  • The main objective is to ensure that all occupants receive ample warning to evacuate the building before smoke, fire, or toxic fumes impede their escape, without needing alarms near high-risk ignition sources.

BS5839:Pt6 Grades:

The Fire Detection Grades are various combinations of Fire Detection and Control / Indicating Equipment. The system designated for your residential property will be classified into one or multiple of the following categories based on your needs.

Grade A

  • A Fire Detection and Alarm system (FD&A) integrates Control and Indicating Equipment (CIE) complying with BSEN54 2 and PSU equipment meeting BSEN54 4 standards.

Grade B

  • An FD&A system includes fire detectors (excluding smoke and heat alarms), fire alarm sounders, and CIE that meets the requirements of Grade A or “Annex C” in this section of BS5839.

Grade C

  • A system of Fire Detectors and Alarm Sounders (possibly combined as smoke alarms) linked to a shared power supply, encompassing the regular mains and a standby supply, with central control equipment.

Grade D1

  • A system of one or more mains powered smoke alarms each with a tamper-proof standby supply consisting of a battery or batteries.

Grade D2

  • A system of one or more mains powered smoke alarms each with an integrated standby supply comprising a user-replaceable battery or batteries.

Grade E

  • A system of one or more mains powered Smoke Alarms without a standby supply. The system may also include one or more Heat alarms, with or without standby supplies.

Grade F

  • A system of one or more battery-powered Smoke alarms, each with an integrated standby supply. The system may also include one or more battery-powered Heat alarms.
