Maritime lithium-ion battery fire detection starts with heat

AP Sensing explains how fibre optic Linear Heat Detection enables earlier lithium-ion battery fire detection on ships through continuous thermal monitoring

On the open ocean, where a ship’s hull is its entire world, fire is one of the few threats that can escalate faster than a crew can respond. Today, that threat is increasingly linked to lithium ion batteries.

Once specialty cargo, they now move through global supply chains in huge volumes, powering electric vehicles, e-bikes, tools, laptops and portable electronics. The maritime industry understands how lithium ion batteries behave under failure conditions.

The chemistry is well studied and the progression from defect to thermal runaway is familiar. What remains difficult is spotting developing thermal events early enough to act. Conventional systems often react only once smoke or fire is visible.

At sea, earlier automatic detection and precise situational awareness can make a critical difference.

How lithium-ion battery fires begin at sea

A lithium ion battery failure usually begins quietly. A defect, manufacturing flaw or Lithium-Ion Battery Fires “The maritime industry understands how lithium ion batteries behave under failure conditions.” impact can cause a small, localised rise in temperature. Inside a battery pack or sealed container, that heat can build slowly and invisibly.

On ships, where containers are tightly stacked and airflow is limited, early detection is difficult. Monitoring still often relies on inspections and fire watches, but thermal events can develop between checks, especially where visibility is restricted.

This is why maritime fire safety is shifting from reacting to visible fire toward continuous, automated awareness of developing thermal conditions.

How fibre optic Linear Heat Detection works

Fibre optic Linear Heat Detection addresses this challenge by continuously monitoring temperature along the protected area.

AP Sensing uses a passive fibre optic sensor cable routed through the ship or cargo zone, creating a continuous sensing line rather than isolated detection points. Wherever the cable runs, temperature is measured.

The system provides thousands of temperature readings along the cable, creating a real time thermal map that updates every few seconds. If thresholds or abnormal thermal developments are detected, it automatically alarms on the bridge, helping crews assess and respond earlier.

How fibre optic sensing detects heat before fire

At the centre of the system is a controller that sends short laser pulses into an optical fibre. As light travels through the fibre, a tiny portion scatters back from every point along the sensor cable.

Part of these backscattered light changes with temperature, while another part remains stable. By comparing the two, the system calculates temperature at every point along the cable. It also measures how long the light takes to return, allowing localised temperature changes to be precisely located.

This creates a complete, real-time temperature profile across the monitored area, not just a reading at one hotspot. Operators can see where heat is developing, how temperatures change and whether a thermal event is spreading.

For lithium-ion battery cargo, where conditions can escalate rapidly, continuous awareness is critical.

Maritime lithium-ion battery fire detection proven at sea

Technology is already proven in demanding environments.

Fibre optic Linear Heat Detection has long been used as a certified special detector within fire alarm systems. Before lithium-ion batteries became a growing maritime concern, it was deployed across road and rail tunnels, parking garages, large photovoltaic installations and storage facilities.

In these settings, reliability is essential. Detection systems must perform despite contamination, electromagnetic interference, vibration, weather and other harsh influences.

Fibre optic LHD has demonstrated this resilience while helping operators maintain safety and avoid unnecessary interruptions. This history is important because the technology is not new to challenging conditions.

At sea, however, airflow, motion and operational constraints create a distinct detection challenge. To explore this, AP Sensing’s system was evaluated alongside conventional and alternative detection technologies in a major European and insurance research initiative focused on fire safety on RoRo (Roll on, roll off) and container vessels. Testing included laboratory work and long-term onboard trials under real operating conditions.

The findings contributed to the inclusion of fibre optic Linear Heat Detection in the maritime SOLAS Fire Safety Systems (FFS) Code in early 2026, reflecting growing recognition of continuous thermal monitoring in maritime fire protection.

AP Sensing’s solution is also DNV-approved for safety-critical ship environments. The results highlighted the limits of traditional smoke detection on ships. In controlled settings, smoke detectors performed well. At sea, airflow, humidity, salt aerosols and engine related particles could delay detection or increase nuisance alarms.

Fibre optic Linear Heat Detection was unaffected by these challenges. Because it measures temperature directly along the cable, it remained reliable regardless of airflow or airborne contaminants.

The trials also showed that the system can reveal how a thermal event develops. It pinpointed the heat source and helped operators track spread and direction, giving crews precise, real-time information instead of a general alarm.

Why fibre optic heat detection suits maritime fire safety

Beyond detection performance, fibre optic Linear Heat Detectors fit maritime operations. The sensing cable is passive and needs no electrical power along its length, simplifying installation and removing potential ignition sources.

The system also remains active during loading and unloading, when cargo handling introduces added risk.

How early heat detection improves maritime fire response

Detecting heat early is only part of the equation. What matters is how quickly and effectively that information becomes action. In a maritime environment, where response time is critical and access can be limited, crews need to know where something is happening and how it is evolving.

Fibre optic sensing provides this insight in real time. Temperature data is processed in the measuring unit and visualised through a graphical user interface (GUI), giving operators a continuous view of conditions across the vessel.

Alarm strategies can be configured around absolute temperatures or temperature gradients, enabling early warnings of abnormal developments before a localised issue escalates.

Lithium-ion battery fire detection beyond maritime transport

With lithium-ion batteries, the challenge does not begin or end at sea. A battery’s journey spans storage, transport, use and recycling. Across these stages, the pattern remains the same: heat develops before fire.

Fibre optic Linear Heat Detection applies this principle consistently. A continuous sensing cable enables early detection and precise localisation, supporting a unified approach to fire safety beyond maritime transport.

This is especially relevant in battery storage facilities, where large volumes of cells are concentrated in confined spaces and in recycling operations, where damaged or unstable batteries add risk during handling and processing.

Across these environments, the value is consistent: early insight enables faster, better-informed decisions and safer operations.

Meet AP Sensing at SMM Hamburg

At SMM maritime exhibition in Hamburg, September 1-4, discussions around lithium-ion battery safety and early fire detection will continue across the industry.

AP Sensing’s fire detection expert, Felix Heck, will be on site to present how fibre optic Linear Heat Detection and Distributed Fibre Optic Sensing are applied in real maritime environments. He will share how continuous thermal monitoring supports earlier detection and more informed response strategies.

Ramtech deploys wireless fire detection system at 2026 Le Mans race

Ramtech has successfully deployed its wireless fire detection technology at the 2026 24 Hours of Le Mans, providing temporary fire protection across key event infrastructure and demonstrating the increasing adoption of automated fire safety systems at major motorsport events.

Working alongside event infrastructure specialist iEvent and integration partner Prodomo, Ramtech France installed a temporary network of more than 300 wireless devices, including smoke and heat detectors and manual call points. The system protected 14 team paddocks and the Genesis Hospitality Building throughout the event.

Installed on a one-month rental basis, the system delivered continuous 24/7 fire monitoring during both the event build-up and race period, with the core live system operating for one week.

The deployment follows a similar installation at the Formula 1 Hungarian Grand Prix, reflecting a broader trend among major motorsport organisers towards wireless fire protection systems that can be rapidly installed and adapted.

Bruna Esposito, Business Unit Director at Ramtech, said: “The environment at a modern Grand Prix or endurance race closely mirrors the extreme complexities of major commercial construction or industrial sites; massive temporary structures, constantly evolving site layouts, tight installation windows and millions of dollars in critical team assets. Managing these risks via manual human patrols is increasingly seen as an outdated and reactive liability.

“We are seeing a fundamental shift in how the world’s largest public events manage fire safety. Rather than relying on traditional, human-led fire watch personnel to manually patrol grounds, tier-one event organisers are embracing automated wireless safety technology to protect people and temporary infrastructure. This project represents an important milestone for Ramtech, demonstrating the trust that global event organisers place in our technology.”

Because the wireless mesh system requires no cabling or conduit, additional devices could be installed or relocated as site layouts evolved during the build-up to race day, allowing organisers to respond quickly to changing operational requirements.

Wireless system chosen for flexibility

Antoine Galicher, Project Manager at iEvent, said: “Flexibility was one of the key reasons we chose Ramtech’s WES system. For an event of this scale, we needed a solution that could deliver both reliability and ease of deployment, allowing us to adapt quickly as requirements changed. The wireless technology simplified installation while helping us maintain the high safety standards expected at Le Mans.”

Sylvain Castaignau, Business Development Manager for Ramtech France, added: “The customer was initially looking for a solution to improve fire safety but was not aware that an automated system like WES existed. From the first demonstration, it became clear that the flexibility and functionality of the system were perfectly suited to an event environment where requirements change daily. This project proves how temporary fire protection can evolve beyond traditional fire watch approaches.”

Ramtech highlights wider event safety trends

Ramtech believes the Le Mans project reflects a wider shift in temporary fire protection for large-scale events, where organisers are increasingly seeking alternatives to manual fire watch patrols.

Esposito said: “With the additional risk posed by increasing summer temperatures and prolonged heatwaves, relying on manual human labour for continuous fire watch patrols introduces major occupational health risks and soaring overtime costs. In addition, there is a heightened concern around the potential for outbreaks of fire, particularly in conditions of dry outdoor spaces, where events may be held.”

The company says the project demonstrates how wireless fire detection technology can provide flexible protection for temporary venues, particularly where layouts change frequently during construction and event preparation.

PFAS-free fire extinguishers: future-proofing fire safety for sustainability and compliance

Andy Spence of Britannia Fire explains how fire safety professionals can prepare for PFAS restrictions, reduce carbon emissions and improve whole-life value through PFAS-free technology, circular economy principles and sustainable procurement

The fire safety sector is entering a period of significant change. Growing environmental expectations, evolving regulations surrounding PFAS and increasing pressure to reduce carbon emissions are prompting organisations to reassess how fire protection products are specified, managed and maintained throughout their lifecycle.

At the same time, budget constraints and supply chain considerations are placing greater emphasis on long-term value rather than upfront cost alone. Future proofing requires organisations to anticipate regulatory change, reduce environmental impact and invest in solutions that deliver long-term operational and financial benefits.

From PFAS free technologies to circular economy principles, the decisions made today will shape both sustainability performance and future resilience.

PFAS regulations and the fire safety challenge

Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS), known as ‘forever’ chemicals, have historically been used in firefighting foams and fire extinguishers because of their unique ability to rapidly suppress flammable liquid fires.

However, they are under intense scrutiny as they do not degrade easily in the environment and can lead to a range of health issues, including decreased fertility, developmental delays in children, a higher risk of certain cancers and immune system suppression.

Across the European Union, regulations restricting PFAS in firefighting foams and extinguishers came into force on 23 October 2025, with a ban in most scenarios taking effect from 23 October 2030. The UK government is also taking this issue seriously.

Earlier this year the Department for Environment, Food and Rural Affairs (Defra) published its PFAS plan, which outlines key steps the government will take to understand, manage and reduce exposure to PFAS. Some action is already being taken, with the Health & Safety Executive (HSE), the agency which regulates chemicals placed on the market in Great Britain (GB), due to report back later this year on how PFAS should be phased out of firefighting foam in the UK.

The HSE is suggesting a staggered approach to phasing out PFAS in firefighting foam and extinguishers, depending on use and type. Looking at the proposed timescales for transition, it’s unlikely fire extinguishers containing PFAS would be phased out before 2031, but what we do know is that they will probably be the first to go – in part due to advances in technology and credible alternatives.

We are expecting the HSE to publish its final opinion later this year, with a decision on UK wide restrictions to follow soon after. As PFAS bans take effect across the EU and the

UK moves towards tighter regulation, those responsible for fire safety need to evaluate their existing assets, develop transition strategies for equipment containing PFAS, budget for replacement costs and manage the complex requirements associated with disposal and environmental compliance.

Transitioning to PFAS-free fire extinguishers and foams

We recognised the detrimental effects of PFAS some time ago and removed them from all our products in 2024. Since then, we have been at the forefront of shaping future fire safety regulation in the UK.

In June last year, I addressed the Environmental Audit Committee in the House of Commons, sharing our experience of phasing out PFAS with the aim of helping policymakers understand both the environmental urgency and the practical realities of a transition.

The emergence of high performing PFAS free solutions is helping to dispel the myth that switching to PFAS free is a compromise. Britannia’s lightweight, composite P50 fire extinguishers are a prime example of how the industry is evolving, combining proven fire suppression performance with PFAS free technology and a reduced environmental footprint.

They are tried and tested in the real world, meaning organisations can confidently transition away from PFAS while maintaining the levels of protection, reliability and compliance that modern fire safety demands.

Organisations need to start thinking about this now. They should review their stock to establish what needs replacing and put in place an action plan as part of their usual fire risk assessments and in accordance with their health and safety asset management plan.

If existing stock is nearing its end of life, has failed an inspection or Knowledge Partner additional units are required, make the switch and get ahead of the ban. Allow time for transition but don’t panic.

Use a reputable supplier that will support and provide advice throughout the process.

Circular economy principles for sustainable fire protection

Future-proofing fire safety requires organisations to look beyond the initial purchase cost and consider the entire lifecycle of their fire protection assets. Factors such as maintenance requirements, replacement frequency, waste generation and end-of-life disposal all contribute to the true environmental and financial cost of a product.

Adopting a lifecycle approach enables organisations to identify solutions that deliver long-term value, reduce resource consumption and minimise carbon emissions. In an era of increasing sustainability expectations, understanding the full lifecycle impact of fire safety equipment is becoming just as important as assessing its firefighting performance.

Composite fire extinguishers and long-life fire safety equipment

Traditionally, steel fire extinguishers have been the go-to solution for facilities managers and fire safety professionals, but they are prone to corrosion and therefore need servicing every year and often replacing every five years.

Composite fire extinguishers, however, are helping organisations to meet stringent waste and carbon reduction targets and simplifying fire safety. They’re made from a unique combination of durable plastic and aramid fibres, meaning they are strong, don’t corrode and therefore last 20 years.

They don’t require costly annual servicing, just simple, efficient in-house checks done as part of an organisation’s routine maintenance programme and a full refurbishment after 10 years.

They are also multipurpose, meaning organisations don’t need as many. Britannia’s composite P50 fire extinguishers are used worldwide and despite some claims to the contrary, they conform to all required regulations and standards, including BS EN3-7.

Delivering long-term cost savings Sustainable products like the P50 are well positioned to deliver long-term savings. High-quality, long-lasting equipment with reduced maintenance and replacement requirements lowers ongoing operational costs, while PFAS free solutions help organisations avoid future disposal expenses and compliance challenges associated with evolving regulations.

P50s are also multi-purpose, capable of tackling Class A and B fires as well as electrical fires, reducing the number of extinguishers needed and saving money.

By taking a whole-life cost approach, organisations can identify solutions that not only support sustainability objectives but also deliver measurable financial benefits over time.

Reducing carbon emissions across the fire safety lifecycle

Manufacturing, transportation, maintenance and end-of-life disposal all contribute to a product’s overall carbon footprint, making it important to look beyond operational performance alone.

By assessing lifecycle emissions rather than simply focusing on purchase price, organisations can identify opportunities to significantly reduce their environmental impact.

For example, selecting composite fire extinguishers that don’t require annual servicing reduces vehicle journeys and associated emissions, while products that don’t need frequently replacing, lowers the carbon costs linked to manufacturing and transportation.

They are also fully recyclable, with solar assisted, low energy manufacturing helping to minimise their carbon footprint. Choosing durable, reusable and recyclable fire safety equipment can therefore make a meaningful contribution to both carbon reduction targets and wider sustainability objectives.

Future-proofing fire safety with sustainable compliance strategies

Fire safety and sustainability are no longer separate considerations. By embracing PFAS-free technologies, lifecycle thinking and circular economy principles today, organisations can strengthen compliance, reduce costs and improve environmental performance. This will ensure that those organisations are well prepared for the challenges and opportunities of the future.

Fire safety compliance for housing providers: Beyond waking watch

Hyfire’s Brett Boyd explains how wireless fire detection is helping housing providers achieve fire safety compliance and reduce reliance on waking watch

For housing providers across the UK, fire safety compliance remains one of the most pressing challenges facing the sector.

As organisations continue to address issues including unsafe cladding, compartmentation failures and inadequate fire stopping, there is increasing pressure to find solutions that not only meet regulatory requirements but can be implemented quickly, cost-effectively and with minimal disruption to residents.

The launch of the Interim Measures Alarm Fund (IMAF) by Homes England in April 2026 is designed to help tackle that challenge, providing funding for housing providers to upgrade fire safety systems in buildings where urgent remedial works are required.

According to Brett Boyd, Regional Sales Manager – South East at Hyfire, the fund represents far more than a financial opportunity. “Compliance is at the centre of it all,” he says. “It’s not just about ticking boxes to access the funding. It’s about making sure systems are actually doing what they’re supposed to do, and that’s protecting people.”

The introduction of IMAF comes at a time when many housing providers are seeking alternatives to temporary fire safety measures while remediation projects are undertaken.

In particular, the industry continues to look for ways to reduce reliance on waking watch arrangements, which can be expensive to maintain over extended periods.

“A big driver behind it has been the need to move away from costly measures like waking watch and towards a more cost-effective and more permanent solution,” says Boyd.

For landlords and building managers, compliance is increasingly about demonstrating that buildings are safe while also providing reassurance to residents.

“Being compliant means housing providers can demonstrate that they are meeting their obligations and can safely step away from things like waking watch, which can be both disruptive and expensive over time,” he explains.

“At the end of the day, compliance gives everyone confidence, from the landlords to the residents. It’s the right level of protection that needs to be in place.”

Delivering fire safety compliance without complexity

While funding provides an opportunity for improvement, implementing compliant fire safety systems can still present practical challenges.

This is particularly true in occupied residential buildings, where traditional hardwired installations can create disruption for residents and significantly extend project timescales.

For Boyd, one of the key advantages of Hyfire’s Taurus system is that compliance has been built into the technology from the outset. “Taurus was developed with real-world challenges in mind, so compliance is built into what we do,” he says.

“Our systems are fully certified and designed to align with the standards that sit behind funding schemes like IMAF.”

However, Boyd is quick to point out that technology alone is only part of the solution.  “One of our big advantages is our network of approved installers,” he explains. “It means organisations aren’t just getting the technology, but also the right expertise to deliver a compliant solution from start to finish.”

That installer network plays an important role in ensuring systems are delivered correctly and in accordance with the latest requirements.

“Installers understand both the technical side and the compliance requirements, which makes the whole process much smoother,” he says.

The flexibility of wireless technology also helps simplify projects that might otherwise be difficult to deliver.

“Because it’s wireless, it gives a lot more flexibility when designing and installing, particularly in buildings where running cables would be difficult or disruptive.” In many cases, speed can be just as important as compliance.

“It’s particularly effective in situations where a fast upgrade is needed,” Boyd adds, revealing that ultimately the goal is straightforward.

“It’s about making compliance more achievable, helping organisations meet funding criteria without overcomplicating the projects that they’re working on.”

Why wireless fire detection is changing the conversation

Wireless fire detection systems have evolved significantly over the last two decades and are increasingly becoming a preferred solution rather than a specialist alternative.

According to Boyd, the technology has transformed the way retrofit projects can be delivered. “Wireless has been a game changer, especially for retrofit projects,” he says.

 “The biggest benefit is the lack of disruption. There’s no need to run cabling through walls and ceilings. Residents can stay in their homes while the system is installed.” For housing providers managing occupied residential buildings, that ability to complete works without requiring residents to relocate can deliver major benefits.

Speed is another important factor. “It’s also much quicker to install, which naturally helps keep costs under control when you look at a whole project,” Boyd explains. “Given the ongoing cost of waking watch, that speed can make a real financial difference.”

One misconception that still occasionally exists within the market is that wireless systems may not offer the same level of reliability as traditional wired installations.

Boyd is keen to challenge that perception. “Modern wireless systems are incredibly robust and perform to the same standards as wired systems,” he says. “There’s no compromise there.” He believes the flexibility of wireless technology is another significant advantage.

“Buildings can change over time and wireless systems can make it easy to adapt without needing major works again in the future.”

Overall, he says, the benefits are clear. “It’s about delivering a safer compliance solution in a way that works for both the building and the people that live in that building.”

Adapting to changing fire safety regulations

As regulations continue to evolve, flexibility is becoming an increasingly valuable feature of fire safety systems. One example is BS 8629, the standard covering evacuation alert systems for use by fire and rescue services in blocks of flats.

For many building owners, the prospect of upgrading systems to meet new requirements can raise concerns about cost and disruption. However, Boyd says this is often not necessary with HyFire systems.

“One of the strengths of Hyfire is how adaptable our system is,” he explains. “If a building needs to meet the requirements of BS 8629, it’s often not a case of ripping everything out and starting again. Instead, we can build on what’s already there.”

In many cases, the process is relatively straightforward. “With proper planning from the outset of a project, it can be as simple as changing out the panel, removing the automatic detectors and doing some basic reprogramming of the system.”

The wireless nature of the technology once again provides a major advantage. “Because it’s wireless, those changes can usually be made without major disruption as well,” Boyd says.

“Residents don’t need to leave their homes.” The approach not only helps simplify compliance but also protects previous investment. “Overall, it’s a pretty straightforward upgrade and it helps protect the original investment in the system as well.”

The future of fire safety compliance

Despite the progress that has been made, Boyd believes housing providers still face considerable challenges. “There’s obviously a lot for housing providers to consider and manage at the moment,” he says.

“Things like compartmentation, unsafe cladding on buildings and substandard fire stopping are major contributing factors and they need to be addressed.” While waking watch remains a common response during remediation works, he believes the industry is increasingly recognising the limitations of the approach.

“While they do provide short-term reassurance, they’re not a sustainable solution and can become very costly over time,” he says. “There’s also the human element to waking watch, where it’s not always as reliable as it should be. Having an automatic detection system can sometimes be a more reliable solution.”

Looking ahead, Boyd sees wireless technology becoming even more prominent across the residential sector. “Where wireless was traditionally always used where cabling couldn’t be installed as a must-have solution, it’s now becoming a go-to solution for a lot of people because the technology has improved over the last two decades.”

Future developments are likely to focus on connectivity and visibility, helping housing providers manage fire safety more effectively across their portfolios. “There’s going to be a bigger focus on smarter, more connected systems that can give housing providers better oversight and control.”

At the same time, resident experience will remain central to decision-making. “When it comes to IMAF, it’s important to note that everything will continue to centre around the residents,” Boyd says.

“The improvements don’t come at a cost of comfort or convenience.” For Hyfire, the long-term objective remains simple.

“We believe in providing the right solution,” he says. “It’s not just about putting something in. It’s the right solution for the right application, solutions that meet the highest standards of safety while still being practical and efficient for the environments that they serve.”

BS 5839-1:2025: Why cyber security is now essential for modern fire alarm systems

Nicholas Whiting, VP Alarm Signalling, AddSecure UK, explains why the updated code of practice reflects the growing need to protect both the physical and digital resilience of modern fire alarm systems

The updated BS 5839-1:2025 code of practice reflects the increasing connectivity of fire alarm systems, introducing stronger guidance on remote access, signalling resilience and system security. As fire alarm technology evolves, cyber security is becoming a core part of protecting life safety and ensuring resilient fire detection.

How BS 5839-1:2025 is reshaping fire alarm best practice

Introduced in 2025, BS 5839-1:2025 replaced the previous 2017 edition, marking a significant evolution in how the fire alarm sector approaches the design, installation, commissioning and maintenance of fire alarm systems in non-domestic buildings. While the standard remains a code of practice rather than a new regulatory requirement, it reflects the growing complexity of connected fire alarm environments and highlights the increasing importance of cyber security alongside fire safety.

As the industry approaches a year since the publication of BS 5839-1:2025, the updated guidance offers valuable lessons on how fire safety and cyber security are becoming increasingly interconnected.

For many years, BS 5839-1 has provided the fire and alarm industry with a framework for good practice. The 2025 revision builds on this by improving fire safety guidance, strengthening detection requirements in higher-risk areas and incorporating lessons learned from major incidents, including Grenfell Tower. The revised code also introduces clearer expectations around documentation, false alarm reduction and protecting vulnerable building occupants.

Key changes for Category L and Category P fire alarm systems

Under BS 5839-1:2025, Category L systems, which prioritise life safety, should use smoke or multi-sensor detectors as the default in sleeping accommodation. Zone plans are now considered essential in multi-zone installations and must be verified for accuracy during maintenance.

For residential care premises, the updated guidance recommends automatic transmission of fire signals to alarm receiving centres, recognising that the absence of remote monitoring is no longer considered acceptable. Meanwhile, Category P systems, designed to protect property, include refreshed guidance on detector positioning around structural obstacles, simplified manual call point distances and enhanced signalling requirements. These include alarm signal transmission within 120 seconds and reporting catastrophic loss of both signalling paths within 31 minutes for dual-path systems.

Why cyber security is now part of fire alarm system design

Perhaps the most significant development within BS 5839-1:2025 is its recognition that fire alarm systems are no longer standalone installations. Modern systems are increasingly integrated into wider building networks, communicate over IP infrastructure and can often be accessed remotely for diagnostics and maintenance.

While these capabilities deliver operational benefits, they also introduce cyber security risks that were largely absent from traditional fire alarm systems. Any system capable of remote access presents the potential for unauthorised interference if appropriate safeguards are not in place.

Historically, engineers were required to attend site to diagnose faults or carry out maintenance. Today’s connected systems allow faster fault identification, earlier notification of issues and, in some cases, remote servicing. However, BS 5839-1:2025 makes it clear that improved functionality must be matched by appropriate security measures.

Although the guidance stops short of mandating specific cyber security controls, it outlines best practice for securing remote access. This includes using secure authentication before connections are established and ensuring equipment used to facilitate remote access is housed within locked cabinets or tamper-resistant enclosures. Whether systems communicate via IP or mobile networks, the revised code reinforces the importance of protecting remote access against unauthorised activity.

Strengthening signalling resilience under BS 5839-1:2025

The updated standard also places greater emphasis on signalling resilience, recognising that reliable communication is fundamental to effective fire protection.

For property protection systems, alarm signals should be transmitted within 120 seconds, while life safety systems are expected to achieve even shorter transmission times due to their higher-risk nature. Dual-path signalling devices must report catastrophic loss of both communication paths within 31 minutes (DP2) for Category P systems, helping ensure faults are detected and escalated promptly.

Dual-path radio systems may be used where they satisfy the reporting requirements for DP2 and DP3. For Category L systems, however, catastrophic failures should be reported within three minutes (DP4), with alarm signals transmitted within 90 seconds. DP3 dual-radio systems should only be used where a documented variation justifies their installation, such as where a fixed IP connection is not technically feasible.

These requirements demonstrate that signalling resilience extends beyond the fire alarm panel itself. As remotely monitored systems become increasingly common, installers are relying more heavily on manufacturers and signalling providers to deliver secure, resilient infrastructure capable of meeting the expectations set out in BS 5839-1:2025.

Training and future resilience

Alongside technological improvements, the revised standard also recognises the importance of ongoing competence. Modern fire alarm systems are active, connected assets that require continual management rather than one-off installation. The guidance recommends that installers invest in continuous professional development to ensure their knowledge evolves alongside increasingly sophisticated systems.

As fire alarm technology continues to become more connected, remotely managed and integrated within wider building management systems, cyber security is no longer a separate consideration. BS 5839-1:2025 demonstrates that protecting connected fire alarm systems now requires both physical and digital resilience. The updated code of practice reflects an industry where fire safety and cyber security are becoming inseparable, requiring manufacturers, installers and building owners to consider both as part of delivering resilient life safety systems.

FireAngel launches Spec+ domestic safety alarms for professional installations

Domestic safety alarms range combines smoke, heat and carbon monoxide protection with flexible interconnection and 10-year battery backup

Domestic safety alarms specialist FireAngel has launched its new Spec+ range, introducing a portfolio of mains-powered smoke, heat, carbon monoxide and multi-sensor alarms designed to simplify installation, improve replacement and support long-term residential fire protection.

Developed for the UK professional market, the Grade D1 alarm range is aimed at installers, landlords, housebuilders and housing providers, with every product featuring a 10-year sealed rechargeable lithium back-up battery and compliance with the requirements of BS 5839-6 for most residential applications.

The Spec+ portfolio includes dedicated smoke, heat and carbon monoxide alarms, alongside multi-sensor devices that combine smoke, heat and carbon monoxide detection within a single unit. The products have been developed to support changing legislation and evolving domestic safety requirements while providing greater flexibility for residential installations.

FireAngel said the new alarms have been designed to make installation and replacement easier through a practical base plate design, while built-in Bluetooth Low Energy (BLE) connectivity enables up to 50 Spec+ devices to be interconnected wirelessly, via hardwired connections or through a hybrid of both without requiring additional communication modules.

The smoke alarms combine the company’s Thermoptek and UltraSense technologies, which operate in parallel to improve fire detection while reducing nuisance alarms caused by contaminants and everyday household activities. Bug mesh and dust compensation features have also been incorporated to improve product longevity and minimise interference that can lead to false alarms.

Across the range, alarms are designed for a 10-year service life and are backed by a 10-year warranty. FireAngel recommends replacing smoke, heat and carbon monoxide alarms after 10 years to maintain optimum protection, even if devices continue to function beyond that period.

The Spec+ range includes the SP500 smoke alarm, SP510 heat alarm, SP520 multi-sensor smoke and heat alarm, SP530 multi-sensor heat and carbon monoxide alarm, and the SP540 multi-sensor smoke, heat and carbon monoxide alarm. Compatible wireless and hard-wired low-level control units are also available.

All products in the range comply with recognised standards for smoke, heat and carbon monoxide detection, including BS EN 14604, BS 5446-2 and EN 50291-1 where applicable. FireAngel said every alarm is individually tested during manufacture and the range carries third-party SGS certification.

Nick Rutter, Chief Executive Officer at FireAngel, said: “Our new Spec+ range represents a significant product portfolio for FireAngel that will enable a step-change for the future of domestic safety. Spec+ has been designed around real installation needs, quality-first design principles and trusted protection for residents.”

He added: “The launch comes at an important time for the fire safety sector, where innovation and healthy marketplace competition are essential to continuously improving protection in homes across the UK. FireAngel believes that bringing new products to market plays a vital role in giving specifiers, contractors and housing providers greater choice, while ensuring safety-critical technology continues to evolve.”

Siemens launches intelligent fire detection and notification systems for smart buildings

Intelligent fire detection portfolio combines connected fire detectors and digital notification technology to support autonomous buildings

Siemens has expanded its portfolio with the launch of a new intelligent fire detection and notification portfolio that combines cloud-connected fire detectors with digital alarm notification systems to improve building safety, reduce maintenance and support autonomous building operations.

The company has introduced its next-generation Sinteso Nova and Cerberus Nova fire detectors alongside the Acend Intelligent notification portfolio, creating an integrated fire safety ecosystem that delivers continuous self-testing, predictive maintenance, remote diagnostics and real-time monitoring. The combined offering is designed for sectors including healthcare, hospitality, commercial real estate, higher education and data centres, where maintaining uninterrupted operations is critical.

Together, the new products transform conventional fire safety into a proactive, connected system that gives building operators greater visibility of system performance while reducing manual maintenance through cloud-based monitoring and diagnostics.

Intelligent fire detection monitoring

The Sinteso Nova and Cerberus Nova fire detectors continuously monitor their own performance using Disturbance-Free Testing (DFT), allowing automated self-checks to take place around the clock without disrupting occupants or building operations. Smoke Entry Supervision (SES) technology monitors smoke entry points in real time, while ASAplus technology combines multi-wavelength optical and dual thermal detection to reduce false alarms and unnecessary evacuations.

The detectors are fully IoT-enabled and integrate with Siemens’ Building X Fire Apps, allowing facility managers and service providers to access real-time monitoring, remote diagnostics, predictive maintenance and shared operational data from connected buildings.

Complementing the new detection portfolio, the Acend Intelligent notification range digitises fire alarm notification through connected horns, strobes, speakers and combination notification appliances that can each be monitored and activated individually.

Its integrated Disturbance-Free Testing technology enables technicians to verify system readiness without triggering audible or visual alarms, helping minimise disruption in environments such as hospitals, hotels, office buildings and data centres. Individual device monitoring also allows faults to be identified more quickly, reducing the need for physical inspections.

The notification portfolio also incorporates Class X isolation technology, ensuring systems remain operational by isolating wiring faults while maintaining protection across unaffected parts of the building.

Peter Nebiker, Head of Fire Safety at Siemens Smart Infrastructure Buildings, said: “The launch of our Sinteso Nova and Cerberus Nova fire detection portfolio is a game-changer in ensuring all alarms are accurate as best as possible. By moving from periodic checks to continuous, data-driven, self-supervising systems, we’re laying the foundation for truly human-centric, autonomous buildings. By automating testing, delivering real-time insights, and enabling remote action, these solutions protect people while freeing up staff to focus on strategic priorities. This shift isn’t just about innovation – it’s about smarter, safer, and more efficient operations.”

Commenting on the launch of Acend Intelligent, Nebiker added: “As buildings become increasingly connected and digitalized, safety systems must evolve alongside them. With Acend Intelligent, we are transforming fire notification into a foundational technology for these next-generation environments by combining cloud connectivity, real-time data, and digital integration.”

The new fire detection portfolio has been designed to simplify modernisation projects by supporting stepwise upgrades while remaining compatible with existing Siemens fire panels, eliminating the need for complete system replacement. Plug-and-play integration and automatic transfer of configured settings help reduce installation time and project risk for both new-build and retrofit applications.

Both the fire detection and notification portfolios have been developed with sustainability in mind. They incorporate recycled materials and carry Siemens’ EcoTech environmental product performance label to provide greater transparency around environmental performance. The Sinteso Nova and Cerberus Nova detectors are also part of the Siemens Xcelerator portfolio, the company’s open digital business platform, and have been developed and manufactured in Switzerland.

The Acend Intelligent notification portfolio is available in markets using UL certification standards, including the United States, Canada and selected countries in Latin America, the Middle East and Asia. Siemens showcased the new notification technology at the 2026 NFPA Conference & Expo in Las Vegas.

KiddeFenwal showcases BESS fire protection solution

KiddeFenwal is using two major fire safety events to highlight a multi-layered fire protection approach designed for battery energy storage systems (BESS), as the sector faces increasing scrutiny over the risks associated with lithium-ion battery installations.

The company, which specialises in fire protection and safety controls, presented its BESS-focused technologies at Interschutz and will also showcase it at the NFPA Conference and Expo. The systems are intended to detect early warning signs of fire and support rapid suppression before incidents escalate into thermal runaway events.

BESS are becoming an increasingly important part of global energy infrastructure, particularly as renewable energy deployment grows. However, their use of lithium-ion batteries can present complex fire risks, including overheating, flammable gas build-up and cell-to-cell fire propagation.

KiddeFenwal said its approach brings together several technologies to provide enhanced protection for BESS applications. These include:

REL-iON – a sensor platform that monitors flammable gases, hydrogen, overheating, refrigerant and water leaks, air temperature and humidity changes, and other early signs of corrosion and fire

Air sampling detection designed to provide early warning of smoke at the incipient stage

AEGIS– PHX and ARIES-SLX fire alarm-suppression control units that can trigger immediate suppression action

Fluoro-K – a clean agent designed to reduce temperature, tackle flames at the source and help stop cell-to-cell propagation without leaving harmful residue

NATURA IG-100 – an inert gas system that uses nitrogen to maintain an oxygen-deficient environment that cannot support combustion, helping prevent re-ignition

According to KiddeFenwal, research conducted at the University of Maryland over a multi-year period, alongside controlled fire tests conducted in December 2025, found that the systems were most effective when used together. The company said the combined approach can quickly detect and suppress initial flames, protect equipment and help maintain safer conditions for first responders.

“The full promise of BESS as reliable and sustainable energy solutions can truly be unleashed when protected with highly sophisticated fire systems,” said Rekha Agrawal, CEO of KiddeFenwal. “KiddeFenwal is advancing the pioneering fire prevention, detection and suppression systems needed for today’s most forward-thinking energy storage companies worldwide.”
