Commercial Fire Alarm Design Services

Almost all buildings in the UK require a fire alarm system of some kind. As a leading fire alarm design company, we can work with your business whether you want to send us drawings which we can mockup into a CAD design or require a free site survey to get things started. 

Here at Britannia Fire and Security, all our computer-aided design (CAD) is conducted in house giving us the utmost flexibility when changes are needed in your project. Our skilled staff are fully qualified and experienced commercial fire. alarm design contractors for many different buildings, including Local Authority, Retail and Leisure. All systems designed are compliant with BS 5839 standards (Fire detection and fire alarm systems for buildings).

When you choose Britannia, you can rest assured you are using an honest and expert fire alarm system designer. We work with your business to find the most suitable system and design for your commercial premises. 

We start by conducting a comprehensive site survey to understand your requirements. We can also conduct a Fire Risk Assessment to check for areas that are non-compliant.

Our experienced designers will then create a fire alarm system design suitable for your requirements and office premises which complies with BS 5839. We can also provide fire alarm monitoring and maintenance for your office to give you a single point of call for all your fire safety requirements.

Fire alarm system design is the process of planning a fire detection and alarm system so it provides effective early warning and meets legal requirements.

The design considers the layout, size, occupancy type, and fire risks of a building. This helps determine the most suitable system type, such as a conventional or addressable fire alarm system. It also defines detector placement, alarm zoning, control equipment, and sounder coverage across the building. A properly designed system helps ensure reliable fire detection and compliance with recognised standards such as BS 5839.

A fire alarm system includes several components that work together to detect fires and alert occupants. The control panel acts as the central unit that monitors the system and displays alerts when devices are activated.

Detectors are installed throughout the building to identify signs of fire, such as smoke or heat. Manual call points are also placed in accessible areas so occupants can trigger the alarm if they discover a fire.

Once activated, sounders and visual alarms warn people in the building to evacuate. The system is supported by a power supply with battery backup so it continues to operate during a power failure. Devices are connected through cabling or wireless infrastructure that allows them to communicate with the control panel.

Effective fire alarm design follows several principles to ensure reliable detection and clear evacuation procedures. Systems are designed using a risk based approach so the level of protection reflects the building’s fire risks and how the premises are used.

Buildings are typically divided into alarm zones so the location of an alarm can be identified quickly. Detector placement must also be carefully planned, taking into account ceiling height, room layout, and airflow.

Fire alarm systems may also include cause and effect programming that defines how the system responds when a device is triggered. Designers often allow for future expansion so additional devices or zones can be added if the building changes.

Fire alarm systems in the UK must comply with recognised standards such as BS 5839, which provides guidance on design, installation, and maintenance.

The system category should match the building’s fire risk assessment and the level of protection required. Installation should be carried out by competent engineers and the system must be tested and commissioned once installed.

Documentation and commissioning certificates should be provided at completion. Ongoing inspection and servicing help ensure the system remains compliant and supports legal duties under the Regulatory Reform (Fire Safety) Order 2005.

From complex integrated packages to simple fire detection systems, we can tailor make a solution to suit your requirements.
