BS 5839-6: Fire Detection and Fire Alarm Systems for Buildings (Domestic Premises)

If you are a property owner or manager in the UK, ensuring fire safety is essential for safeguarding the lives of your residents. This article examines the British Standard BS 5839-6, which specifies the minimum fire safety criteria for newly constructed buildings. Understanding this standard will enhance your ability to develop a secure and compliant fire alarm system.

The British Standard BS 5839-6 determines guidelines for the design, installation, commissioning, and maintenance of fire detection and fire alarm systems in domestic premises. It is essential for the welfare of residents, landlords, property managers, and fire safety professionals. The standard is a component of the broader BS 5839 series, which encompasses fire alarm systems in various property categories.

The objective of BS 5839-6:

The primary objective of BS 5839-6 is to decrease the risk of fire-related casualties and property damage by setting up a fire detection system that is both dependable and efficient. This standard ensures the design and implementation of fire alarm systems to meet the specific needs of diverse residential environments.

The primary objectives are as follows:

• Defining the Minimum Fire Safety Requirements: The standard establishes the Minimum Fire Safety Requirements to ensure that buildings are designed and constructed with fire safety in mind.

• Guaranteed public safety: BS 5839-6 endeavours to safeguard occupants from fire-related hazards and guarantee public safety by offering recommendations for the design, installation, and maintenance of fire alarm systems.

• Promoting adherence to UK fire safety regulations: BS 5839-6 is a critical element of the UK’s fire safety regulations, and adhering to its guidelines guarantees that buildings satisfy the minimum fire safety standards.

• Aiding in the advancement of fire alarm systems that are both efficient and effective: By adhering to the standard, designers and installers can create efficient systems that are tailored to the requirements of newly constructed buildings.

Covered by BS 5839-6 are the subsequent domestic building types:

• Cottages
• Houses with multiple stories
• Individual apartments
• Individually owned residences
• Mobile houses
• Mansions
• Shared housing
• Individual sheltered accommodation and its common components
• Houses in multiple occupations (HMOs)
• Specific NHS residences in the community
• Houses that have been partitioned into multiple self-contained single-family dwelling units

Fire Alarm Grades and Categories

BS 5839-6 classifies fire alarms according to their ability to identify fires, with a particular emphasis on those that originate from thermal or electrical sources. 

The following are the grade categories:

Grade C: A system that includes fire detectors and alarm sounders (which may be domestic smoke alarms) is connected to a common power supply that comprises a standard mains and standby supply, as well as central control equipment.

Grade D1 & D2: A system including one or more interconnected mains-powered smoke alarms (and heat alarms if necessary), each equipped with an integral standby power supply. They may be interconnected via hardwiring or radio transmission.

• Grade D1: The standby supply must be tamper-proof and maintain its functionality for the duration of the alarm.
• Grade D2: The standby supply is user-replaceable and will not endure for the entire lifespan of the alarm.

Grade F1 & F2: A system comprising one or more battery-operated smoke alarms (and heat alarms if necessary).

• Grade F1: The battery must be resistant to alteration and last for the entire duration of the alarm’s lifespan.
• Grade F2: The battery is user-replaceable and will not endure for the entire lifespan of the alarm. 

Categories of Fire Alarms:

• Category LD1: Optimum protection, featuring smoke and heat detectors in all livable spaces and circulation zones.
• Category LD2: Improved protection, featuring detectors in high-risk zones such as kitchens and evacuation pathways.
• Category LD3: Essential protection, covering solely escape routes.

Classification of Alarms and Criteria for Detection Performance

The categorisation of alarms is predicated on the criteria for detection performance, which are enumerated as follows:

• Detection Performance: The capability of an alarm to identify the existence of a fire.
• Notification Performance: The capacity of an alarm to alert inhabitants to a potential fire threat.

Essential Aspects of BS 5839-6

• Efficient detection and notification: The detection and notification functions of fire alarms are essential for safeguarding occupants against potential fire threats.
• Performance standards ensure compliance: The performance requirements guarantee that fire alarms adhere to defined standards for detection and notification.
• Difference in detection performance: The level of detection required varies based on the type of fire, with Class 1 alarms having stronger detection performance.

Suggested Strategies for Executing BS 5839-6

Property owners and managers should adhere to BS 5839-6 compliance requirements.

• Partner with a certified fire safety engineer or designer: They can help you develop a design that adheres to the standard’s criteria.
• Ensure the proper installation of all components: This encompasses manual pull stations, smoke detectors, and other essential components.
• Conduct routine inspections and maintenance: Routine inspections will mitigate the risk of system failure during fire incidents.

Conclusion:

BS 5839-6 is an essential standard for the protection of domestic premises in the United Kingdom from fire. The establishment of clear standards for the design, installation, commissioning, and maintenance of fire detection and alarm systems is essential in the reduction of fire-related casualties and property damage. The standard guarantees the categorisation of fire alarms into various classifications and categories, thereby offering tailored solutions for diverse residential environments.
