BS5839-1 Fire Alarm

BS5839-1 is a specific part of the British Standard that provides recommendations and guidelines for the design, installation, commissioning, and maintenance of fire detection and fire alarm systems in non-domestic premises in the UK. It covers a wide range of commercial, industrial, and public buildings, including offices, schools, hospitals, retail stores, and other similar environments.

Here is an overview of a BS5839-1 fire alarm system:      

  1. Design Requirements: BS5839-1 emphasises the importance of a well-designed fire alarm system tailored to the specific premises. It considers factors such as the size, layout, and purpose of the building, as well as the potential fire risks associated with the occupancy and activities within the premises. 

  2. Alarm Zones and Categories: The standard defines alarm zones and categories, which help determine the type and positioning of fire detectors, manual call points, and alarm sounders. These zones and categories are based on factors such as the level of fire risk and the need for phased evacuation.     

  3. Detection Devices: BS5839-1 provides guidance on the selection, positioning, and spacing of fire detectors, including smoke detectors, heat detectors, and multi-sensor detectors. It considers factors such as the environment, the presence of potential false alarm sources, and the specific fire detection needs of the premises.  

  4. Alarm Sounders and Notification Devices: The standard outlines the requirements for audible and visual alarm devices, including their audibility levels, suitable locations, and activation methods. It considers the need for specific devices for individuals with hearing impairments. 

  5. Control and Indicating Equipment: BS5839-1 specifies requirements for fire alarm control and indicating equipment, including the design and functionality of control panels, repeater panels, and associated interfaces.

  6. System Testing and Maintenance: The standard provides recommendations for regular testing, inspection, and maintenance of the fire alarm system to ensure its ongoing reliability and compliance. It includes requirements for recording test results and establishing maintenance procedures.

Compliance with BS5839-1 ensures that fire alarm systems in non-domestic premises meet the recommended standards for effective fire detection, alerting, and evacuation, promoting the safety of occupants and minimising the risk of fire incidents.
