BS5839 Cable

BS5839-1 is the British Standard that provides guidance on the design, installation, commissioning, and maintenance of fire detection and fire alarm systems in non-domestic premises. BS5839 fire alarm & security cable is intended to continue working under fire conditions up to the rated period (30 minutes for standard, 120 minutes for enhanced).

Designed for use in low rise buildings (standard) and multi-storey or high-rise tower blocks (enhanced), in applications ranging from security lighting to fire detection and alarm circuits.

Fire Resistance: BS5839-1 specifies two types of fire resistant cables: standard and enhanced. Standard cables are suitable for most fire alarm systems, while enhanced cables are designed for buildings where evacuation may be delayed or require more time.

Applications: BS5839 cables are used in various applications, including fire detection, fire alarm, voice alarm, and emergency lighting circuits, in buildings ranging from low-rise to high-rise.

Standard vs. Enhanced: Standard fire resistant cables are typically used in general applications, while enhanced cables are used in situations requiring extended fire resistance, such as in high-rise buildings or buildings where evacuation is expected to be delayed.
