Fire Detection & Alarm Systems

From initial design through to commissioning and ongoing maintenance, we deliver BS 5839-1 compliant fire detection and alarm systems for all premises types across Essex, London, Hertfordshire, Kent and Suffolk. Every system is designed to suit your specific occupancy and risk profile.

BS 5839-1

BS 5839-1 is the British Standard governing the design, installation, commissioning, and maintenance of fire detection and fire alarm systems in non-domestic premises. Compliance is expected by insurers, enforcing authorities, and building control — and is referenced directly by approved documents in building regulations. All our systems are designed, installed, and certificated to meet this standard.

System Types

The Right System for Your Building

Category L — Life Protection

Designed to protect the occupants of a building. L1 provides the highest level of protection with detectors throughout all areas. L2 through L5 offer targeted protection of specified escape routes and areas.

Category P — Property Protection

Designed to provide early warning to protect the building and its contents. P1 covers all accessible areas; P2 covers defined higher-risk areas such as plant rooms or high-value storage.

Category M — Manual Systems

Manual call point-only systems where automatic detection is not required. Typically used in lower-risk premises or as part of a broader life safety strategy.

Addressable Systems

Each device has a unique address, enabling rapid fault or alarm identification. The preferred choice for larger or more complex buildings where precise zone information is critical.

Conventional Systems

A cost-effective solution for smaller premises. Devices are wired in zones, providing an alarm indication by zone rather than individual device.

Wireless Systems

Radio-linked devices remove the need for disruptive cable runs. Ideal for listed buildings, phased installation, or temporary detection requirements.
