The right system for your building, fitted and looked after properly.

A fire alarm has one job: to give people enough warning to get out. Getting that right depends on how the building is used, who is in it and when, and what your fire risk assessment says. That is why every new system starts with a site visit rather than a price off a list.

We fit conventional, addressable and wireless systems, and we service most makes of panel, including Advanced and Kentec. If you already have a working system there is no need to replace it just because you are changing supplier. We will inspect it, tell you honestly what condition it is in and put it on a maintenance plan.

We are BAFE and SSAIB registered and a Kentec Installation Partner, and we work to BS 5839-1 for non-domestic buildings and BS 5839-6 for homes and flats.

What we install

The systems we install

Conventional systems

Detectors and call points are wired in zones, so the panel shows which zone has gone into alarm. A cost-effective choice for smaller buildings with a simple layout.

Addressable systems

Every device has its own address, so the panel tells you exactly which detector or call point has activated. Better for larger or more complex buildings and quicker to fault-find.

Wireless systems

Devices talk to the panel by radio, with little or no cabling. Ideal for listed buildings, occupied premises and temporary sites where running cables would be disruptive.

Domestic and HMO systems

Interlinked smoke and heat alarms to the right grade and category of BS 5839-6 for homes, flats and houses in multiple occupation.

Interfaces and cause and effect

Links to door holders, access control, lifts, plant shutdown and alarm receiving centres, so the rest of the building responds correctly when the alarm sounds.

Upgrades and extensions

Extending an existing system after a refurbishment or change of use, or replacing an old panel while keeping the cabling and devices that are still sound.

Standards and your responsibilities

What you need to know

We work to BS 5839-1 and BS 5839-6.

The law

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for a non-domestic building must make sure its fire alarm is kept in working order.

Weekly test

Someone on site should operate a different call point each week and record it in the log book. We show you how when we hand the system over.

Six-monthly service

BS 5839-1 recommends a competent person inspects and tests the system at least every six months.

FAQs

Fire alarms questions

How often does a fire alarm need servicing?

BS 5839-1 recommends that a competent person services a fire alarm in a non-domestic building at least every six months. A call point should also be tested every week by someone on site.

What category of fire alarm do I need?

It depends on your building and your fire risk assessment. Most workplaces need at least an L3 or L2 system to protect escape routes, while sleeping risks such as care homes and hotels usually need more detection. We recommend a category after the site survey.

Can you take over a fire alarm installed by another company?

Yes. We service most makes of panel. We start with a full inspection, report what we find and then add it to a maintenance plan.

Our fire alarm keeps going off. Can you fix it?

Usually, yes. Unwanted alarms almost always have a cause, such as a detector in the wrong place, dust, steam or a failing device. We find the cause and fix it rather than just resetting the panel.

What happens after installation?

We commission the system, hand over the certificates and zone plan, and show whoever looks after the building how to use the panel and carry out the weekly test.

What changed in BS 5839-1:2025?

A new version of the standard was published in 2025. We have written a plain-English summary of what changed and what it means for existing systems.
