Why are fire alarms in high rise buildings so important?

Fire alarms in high rise buildings are critical because taller structures present unique evacuation challenges, extended escape routes, and higher occupant numbers. A robust high rise fire alarm system provides early detection and clear alerting, which is essential to ensure safe evacuation and effective emergency response.

What makes a high rise fire alarm system different from a standard system?

A high rise fire alarm system is designed to cover multiple floors, stairwells, and communal areas with enhanced detection and zoning. It must support complex evacuation strategies, often integrating with voice alarm systems, evacuation alert systems, and fire service interfaces — far beyond what standard single-storey systems require.

Are fire alarms in high rise buildings required by law in the UK?

Yes. Fire alarms in high rise buildings are a key component of UK fire safety law and guidance. Buildings over 18 metres (or typically 7 storeys) must have a suitable fire detection and alarm system as part of their fire strategy, documented in a fire risk assessment and maintained in compliance with BS 5839-1 and related guidance.

Who is responsible for ensuring a high rise fire alarm system is compliant?

The Responsible Person (often the building owner, facilities manager, or managing agent) must ensure the high rise fire alarm system is installed, tested, and maintained in line with fire safety regulations. This includes regular servicing, fault monitoring, and reviews of system performance against fire risk assessments.

How do fire alarms in high rise buildings help with evacuation?

Fire alarms in high rise buildings alert all occupants simultaneously and can integrate with pre-planned evacuation strategies — whether phased evacuation or simultaneous evacuation. Clear alarm signals and zone identification help reduce confusion and support faster, safer movement to escape routes and assembly points.

How often should a high rise fire alarm system be serviced?

A high rise fire alarm system should undergo routine checks weekly (by onsite personnel) and be professionally serviced at least every six months. Given the complexity of high rise systems, more frequent inspections help ensure reliability and compliance with BS 5839-1.

Fire Alarms In High-Rise Buildings: Why Every Building Needs One

6 months ago

Ensuring robust fire safety in high-rise buildings has never been more critical. The tragedy of the Grenfell Tower fire, has underscored the vital importance of having effective fire alarms in high-rise buildings. They are a critical component of any effective fire safety strategy that can save lives and protect property.

In this blog, we explore the key reasons why every high-rise building needs a complete fire alarm system in more detail, along with the current requirements for fire alarms in high-rise buildings following Grenfell.

What are the current fire alarm system requirements for high-rise buildings?

In England, the specific fire alarm system requirements for high-rise buildings, especially blocks of flats, have evolved massively following the Grenfell Tower fire. Some of the most notable pieces of guidance provided by the UK government and the Regulatory Reform (Fire Safety) Order 2005 state that:

High-rise residential buildings over 18 metres (or 7 storeys) must have a robust fire detection and alarm system suitable for the building’s design and fire strategy.
A comprehensive and up-to-date fire risk assessment must be undertaken, taking into account the building’s construction, occupancy, and fire safety management procedures.
Common areas such as corridors, stairwells, and lobbies should be equipped with appropriate fire detection and alarm systems to facilitate safe evacuation.
Buildings that have transitioned from a “stay put” strategy to a simultaneous evacuation strategy must be fitted with a full communal fire alarm system capable of alerting all occupants.
New high-rise residential buildings are advised to install an evacuation alert system in which firefighters can use to begin evacuation procedures in the event of a fire.

This guidance highlights the critical importance of having a professionally installed, fully operational fire alarm system tailored to the unique risk of each high-rise building.

5 reasons to have a high-rise fire alarm system

As we’ve briefly mentioned, high-rise buildings pose unique fire safety challenges due to their height, complex layouts, and the number of occupants that either live there, or pass through each day. This means that evacuations can take longer, and fires can spread quickly across floors.

With that in mind, here are five key reasons why every high-rise building should have a complete fire alarm system.

They’re life saving

Fire alarms provide the earliest possible warning, enabling swift evacuation and reducing any potential injuries. Early alerts can also mean the possibility of a life or death situation, particularly in taller buildings where evacuation times are longer, and paths to exits are more complex. Even just a few minutes delay in warning can have devastating consequences, emphasising the importance of fire alarms in high-rise buildings.

They support simultaneous evacuations

Following Grenfell, many high-rise buildings have shifted from “stay put” policies to simultaneous evacuation strategies. With that, a complete fire detection and alarm system is essential for this policy to work effectively as they ensure all residents are immediately alerted to a fire outbreak and can begin evacuating without confusion or delay.

They enhance fire service coordination

With a fully integrated high-rise fire alarm system, it can support local fire services by helping to identify the location of the fire, activate other control measures such as fire sprinklers or ventilation systems, and assist firefighters in prioritising areas for evacuation and fire suppression. This then enables fire services to coordinate a faster, more targeted response, helping to save lives and limit property damage.

They fulfil fire safety responsibilities

Since the introduction of the Building Safety Act 2022 and the Fire Safety (England) Regulations 2022, obligations and responsibilities surrounding fire safety in high-rise buildings have tightened considerably. Installing a full fire alarm system not only protects lives but also ensures you’re adhering to your responsibilities as a “responsible person” or an “accountable person”.

They instil confidence to occupants

The psychological impact of fire risk should not be underestimated. Building occupants deserve to feel safe in their home or place of work, especially in high-rise properties that can be perceived as vulnerable to fire incidents. A visible, well-maintained fire alarm system provides peace of mind and demonstrates your commitment to your occupants safety as a building owner.
