🚨 Commercial Fire Alarm System Design, Installation & Commissioning

A correctly designed and installed fire alarm system is one of the most important life safety systems within any commercial, residential or public building. It provides early warning in the event of fire, supports safe evacuation and helps the Responsible Person demonstrate that suitable fire safety measures are in place.

At Kings Fire, we provide professional fire alarm installations, upgrades, alterations, wireless fire alarm systems and commissioning for businesses, landlords, managing agents, schools, healthcare premises, warehouses, offices, residential blocks and commercial buildings across Bedfordshire, Hertfordshire, Buckinghamshire, Cambridgeshire, Northamptonshire, London and the surrounding Home Counties.

Our experienced fire alarm engineers install systems in accordance with BS 5839-1:2025, helping ensure your fire detection and alarm system is suitable for the building, the occupancy, the fire risk and the required system category.

🧯 Why Your Fire Alarm Installation Must Be Correctly Designed

A fire alarm system should never be installed as a "one size fits all" solution. The correct system category, detector coverage, call point locations, sounder levels, zoning and control equipment should all be based on the use of the building and the findings of the fire risk assessment.

Before providing a fire alarm installation quotation, we will usually need to understand:

• The type and use of the premises
• The existing fire risk assessment findings
• The required fire alarm category, such as M, L1, L2, L3, L4, L5, P1 or P2
• The building layout and escape routes
• Sleeping risk, vulnerable occupants or higher-risk areas
• Existing fire alarm equipment, if any
• Any monitoring, landlord, insurer or enforcing authority requirements
• Access arrangements and business continuity needs
• Whether a wired, wireless or hybrid system may be most suitable

Where the required system category is not already confirmed, this should normally be determined by a suitable fire risk assessment or fire strategy before installation works are agreed.

📘 Fire Alarm Systems Installed to BS 5839-1:2025

Kings Fire installs commercial fire alarm systems in accordance with BS 5839-1:2025, the code of practice for fire detection and fire alarm systems in non-domestic premises.

Depending on the requirements of your building, we can assist with:

• New commercial fire alarm installations
• Fire alarm system upgrades
• Fire alarm panel replacements
• Extensions to existing systems
• Wired and wireless fire alarm system options
• Wireless fire alarm systems for buildings where new cabling is difficult or unsuitable
• Additional detection, call points or sounders
• Changes following a fire risk assessment
• Fire alarm cause and effect requirements
• Fire alarm monitoring connections
• Commissioning and certification
• Ongoing fire alarm servicing after installation

Our aim is to provide a system that is compliant, practical, reliable and suitable for the premises, rather than simply installing unnecessary equipment.

📡 Wireless Fire Alarm Systems

While traditional wired fire alarm systems are still suitable for many premises, there are some buildings where installing new fire alarm cabling can be difficult, disruptive or impractical.

Kings Fire can also provide modern wireless fire alarm systems where appropriate. These can be particularly useful for buildings where new wiring is not suitable due to the layout, construction, age of the building or the nature of the business operating inside.

Wireless fire alarm systems may be a practical option for:

• Heritage or listed buildings
• Occupied offices
• Schools and colleges
• Hotels and hospitality premises
• Retail environments
• Medical and healthcare premises
• Buildings with decorative finishes
• Sites where business disruption must be kept to a minimum
• Temporary or changing layouts
• Premises where cable routes are difficult or unsuitable
• Buildings where visible cabling would affect the appearance or operation of the premises

Modern wireless fire alarm systems can provide a flexible alternative to traditional hard-wired installations, reducing disruption, installation time and the need for visible cabling in sensitive areas.

However, wireless fire alarm systems must still be correctly designed, installed, commissioned and maintained. They are not simply a shortcut or a way to avoid proper fire alarm design. Our engineers will assess the building, the fire risk assessment requirements and the suitability of wireless equipment before recommending this type of system.

Where wireless is suitable, it can provide a professional, compliant and practical fire alarm solution for buildings where a fully wired installation may not be the best option.

🏢 New Fire Alarm Installations

If your premises does not currently have a suitable fire alarm system, we can carry out a site survey and provide a clear quotation for a new installation.

This may include:

• Fire alarm control panel
• Manual call points
• Smoke detectors
• Heat detectors
• Sounders and visual alarm devices where required
• Wired, wireless or hybrid system options
• Zone plans
• Fire-resistant cabling where applicable
• Battery standby
• Labelling and identification
• System testing and commissioning
• Handover documentation and certification

We will explain what has been allowed for, why it is required and whether there are any options available depending on the building and risk profile.

🔄 Fire Alarm Panel Replacements

In many cases, a full fire alarm replacement is not necessary. If your existing system wiring and field devices are suitable, it may be possible to replace or upgrade the fire alarm control panel instead.

A panel replacement may be required where:

• The existing panel is obsolete
• Replacement parts are no longer available
• The panel is unreliable or showing repeated faults
• The system no longer meets the needs of the building
• Additional zones, devices or functions are required
• The existing panel cannot support monitoring or future expansion

Where possible, we will always look for a practical and cost-effective solution before recommending a full system replacement.

🛠️ Fire Alarm Upgrades & Alterations

Buildings change over time. Internal layouts are altered, rooms are repurposed, tenants move in, extensions are built and fire risk assessment findings change.

Kings Fire can carry out fire alarm alterations and upgrades to help ensure your system remains suitable for the building.

Typical fire alarm upgrade works include:

• Additional smoke or heat detection
• New manual call points
• Additional sounders
• Visual alarm devices
• Changes to fire alarm zoning
• Fire alarm works following refurbishment
• Detection added to high-risk rooms
• Alterations following fire risk assessment actions
• Upgrades to support fire alarm monitoring
• Conversion or partial upgrade to wireless equipment where suitable

We can also review existing fire alarm systems and advise whether remedial works, upgrades or replacement may be required.

📞 24/7 Fire Alarm Monitoring

For premises where an activation needs to be responded to quickly, Kings Fire can supply and install fire alarm monitoring equipment through EMCS, the UK's largest independent Alarm Receiving Centre.

Fire alarm monitoring can be particularly useful for:

• Schools
• Warehouses
• Commercial buildings
• Residential blocks
• Care premises
• Unoccupied buildings
• Multi-site businesses
• Higher-risk premises

A monitored fire alarm system can provide additional reassurance by ensuring activations are received by an Alarm Receiving Centre, rather than relying only on someone being on site.
