How Thermal Expansion Tanks Prevent Pressure Damage in Fire Protection Systems

Water doesn’t compress. That one fact causes more quiet damage in sprinkler work than almost anything else. Warm the water inside a closed-loop fire protection system by even a few degrees, and it wants more room, but the piping is sealed, so instead of expanding, it just pushes. Hard. Pressure climbs, gauges creep up, and everything from valve seats to pipe threads takes the strain.

A thermal expansion tank fixes this in the least dramatic way possible: it gives that extra water somewhere to go. Nothing electronic, nothing that needs resetting. Just a steel vessel with an air cushion inside that soaks up the swelling and lets it back out when things cool down. Skip it, and sprinkler system pressure fluctuations will slowly work on your weak points: a weeping relief valve here, a damp fitting there. Good fire protection system pressure control isn’t glamorous, but it’s a big part of why automatic fire sprinkler systems actually work when the day comes. So here’s how the thermal expansion tank does its job, and how to size, fit, and look after one.

Why Thermal Expansion Occurs in Fire Protection Systems

Water expands when it warms. Not by much, in percentage terms, but in a sealed pipe, “not much” is plenty. Sunlight on exposed pipe, a warm ceiling void in July, heat drifting off nearby plant equipment: any of it will do. In an open system, the extra volume would just push back toward the supply, and nobody would notice. In a closed-loop fire protection system, though, a backflow preventer sits between the piping and the main, allowing water to flow only one way. The water is trapped.

That’s really all there is to thermal expansion in sprinkler systems. Sealed pipe, warming water, nowhere to go. A 10–15°C rise can add several bar of pressure, which sounds abstract until you watch a gauge that reads 8 bar at breakfast sitting at 12 by mid-afternoon. People sometimes blame the water supplier for sprinkler system pressure fluctuations like these. Usually, it’s not them; it’s physics at work inside the building. Once you understand thermal expansion in sprinkler systems, the daily gauge wobble stops being a mystery and starts being a warning.

Pressure Changes in Closed-Loop Sprinkler Systems

Every heat-up and cool-down is a stress cycle. Joints flex a little, gaskets compress, gauge internals get hammered. Do that twice a day for five years and something gives, usually a threaded joint or a gauge connection- and usually at a bad time. Without a thermal expansion tank or some other form of fire sprinkler system pressure relief, the piping itself absorbs every one of those cycles.

How Thermal Expansion Tanks Control Pressure in Fire Sprinkler Systems

A thermal expansion tank is a sealed steel vessel teed into the sprinkler piping. Inside, a rubber diaphragm (or bladder) splits it in two. Water on one side, pressurized air or nitrogen on the other, with the air charge set to match normal system pressure. When the pipework warms and the water expands, the surplus water enters the fire sprinkler expansion tank, compressing the air cushion. Pressure still rises, but gently and by a known amount instead of spiking. When the water cools, the air pushes it back out. The system stays full the whole time.

That’s fire protection system pressure control with no moving parts, no power, no software. HVAC people have leaned on the same trick forever; a hydronic expansion tank does exactly this in a heating loop. The fire-service version is built to sprinkler-pressure ratings and functions as a dedicated thermal expansion control system rather than a comfort-heating accessory, but the physics is identical. And compared with letting a relief valve dump water every afternoon? No contest. The tank wastes nothing and keeps the entire network more stable.

Diaphragm and Air Cushion Functionality

The air charge is the working part. Set it right, and the cushion starts absorbing expansion the instant pressure edges past normal quiet, immediate fire sprinkler system pressure relief, long before the mechanical relief valve has any reason to lift.

Preventing Pressure Damage with Fire Protection Expansion Tanks

An expansion tank for fire sprinkler systems interrupts that in three ways. It caps the peak pressure below the ratings of the pipes, couplings, and heads, so nothing runs near their limits. It kills the constant cycling that fatigues gaskets and joints. And it lets the relief valve stay shut, which matters more than people think, because a relief valve that opens daily eventually stops reseating properly, and then you’ve got a permanent drip.

That’s fire system pressure damage prevention in a nutshell: stop the event before it exists, rather than mopping up after it. Buildings that retrofit with a properly sized thermal expansion tank tend to see fewer leak call-outs, fewer dead gauges, and control valves that last as the catalog said they would. Cheap insurance, honestly. Real fire system pressure-damage prevention costs a fraction of what a burst fitting above a finished ceiling will.

Protecting Fire Sprinkler Piping and Components

Fire sprinkler piping protection begins with a steady gauge. When the tank absorbs the swings instead of the pipework, hangers, seams, and welds stop getting flexed twice a day. Sensible fire sprinkler system testing also spares the delicate stuff: flow switches, pressure switches, gauges, which are calibrated for a range and drift out of it when they’re repeatedly over-pressurized. So fire sprinkler piping protection isn’t one local fix; the whole network feels it.

Benefits of Thermal Expansion Tanks in Fire Protection Systems

Stable pressure means alarm and supervisory devices sit inside their intended range, so you chase fewer nuisance trouble signals. The relief valve stays dry, so no treated water goes down the drain, and the discharge pipe doesn’t corrode from constant weeping. Inspection reports get boring gauge readings that don’t swing with the weather, and boring is exactly what you want in this trade. Over the long haul, tidy fire protection pressure management just costs less. 

Seals last, valve seats last, and the maintenance budget stops absorbing surprises. A fire sprinkler expansion tank helps at inspection time too, since chronic overpressure is the kind of thing that gets flagged now. And because it’s a passive thermal expansion control system, there’s nothing to program and nothing to reset after a power cut. For the price of a thermal expansion tank, proactive fire protection system pressure control is one of the easier decisions a building owner will make all year.

Installing Thermal Expansion Tanks in Fire Sprinkler Systems

A thermal expansion tank only works if it’s connected where the problem is on the system side of the backflow preventer, inside the closed-loop fire protection system. Typically that means near the riser, on a tee with an isolation valve so it can be serviced without draining everything. Put it somewhere a person can actually reach it, keep it out of freezing spaces, and support it independently; a tank full of water is heavier than it looks and shouldn’t hang off the pipework.

One step is often skipped: the air pre-charge must be set to the system’s static pressure before commissioning. Wrong charge, and the diaphragm is either already flattened or refuses to accept water; either way, you’ve installed a decoration. Ratings and materials need to follow the design standard; in most places that’s NFPA 13 from the National Fire Protection Association, and manufacturers like Watts publish sizing and pre-charge tables for their vessels. A word of caution: a standard hydronic expansion tank off the heating shelf can look identical to a fire-rated one. Looks aren’t ratings. Check the listing.

Selecting the Right Expansion Tank Capacity

Sizing an expansion tank for fire sprinkler systems comes down to four numbers: total system water volume, expected temperature swing, static supply pressure, and the maximum pressure you’re willing to see. Too small and the tank fills up and quits. Too big and you’ve paid for steel you’ll never use. A well-chosen fire sprinkler expansion tank rides out the worst seasonal sprinkler system pressure fluctuations with room to spare, keeping peaks comfortably under the relief valve’s set point.

Maintaining Thermal Expansion Tanks for Reliable Fire Protection Performance

Tanks fail quietly. That’s the problem. A diaphragm can split, and the system continues to look normal right up until the pressure swings return. So fold the tank into your regular NFPA 25 inspection routine. Isolate and drain the water side, check the air pre-charge with a tire gauge, look the shell and connections over for rust, and confirm the isolation valve is locked open before you leave. A waterlogged tank gives itself away: it’s heavy, and its gauge tracks system pressure exactly instead of holding its own charge. 

Recharge or replace it straight away, because a dead thermal expansion tank protects nothing.

Gauge trends logged during routine fire sprinkler system testing are the cheapest early warning you’ll get; if the daily swing starts widening, the cushion is going. Pair that with fire sprinkler system pressure relief valve testing, and you’ve covered both layers of defense. Maintenance is the unglamorous half of fire system pressure damage prevention, and it’s what keeps the thermal expansion control system honest.

Final Verdict

To sum this up, none of this is complicated, which might be why it gets overlooked. Thermal expansion in sprinkler systems happens every single day the temperature moves; the only question is whether the pipework absorbs it or a thermal expansion tank does. Size the vessel properly, fit it on the right side of the backflow preventer, and check the charge once a year to get durable fire protection, pressure management, and genuine fire sprinkler piping protection for less than the cost of repairing one ceiling.

Frequently Asked Questions

What is the purpose of a thermal expansion tank in a fire protection system?

It gives heated, expanding water a place to go. The tank’s internal air cushion absorbs the excess volume, so system pressure stays within a safe band rather than spiking against sealed pipework.

How does a thermal expansion tank prevent pressure damage in fire sprinkler systems?

Expanding water compresses an air charge behind a rubber diaphragm inside the vessel. Air gives; water doesn’t. That caps peak pressure and removes the daily stress cycles that fatigue joints, gaskets, and gauges.

Why does thermal expansion occur in closed-loop fire protection systems?

Water expands when heated, and in a closed-loop system with no place for the extra volume, pressure builds up.

Where should a thermal expansion tank be installed in a fire sprinkler system?

It is typically installed on the system’s supply side, near the backflow preventer or pressure-reducing valve, following the manufacturer’s and local code requirements.

How often should thermal expansion tanks in fire protection systems be inspected?

They should be inspected during routine fire protection system maintenance, with at least annual checks or as required by local codes and applicable standards.

AI Fire Detection Boom: 2026 Fire Safety Tips for Facilities

Fire safety has always been a matter of life and property. But in 2026, the situation has changed. AI fire detection systems are no longer futuristic novelties; they are operational realities being deployed across warehouses, hospitals, data centers, and manufacturing plants worldwide. As facilities grow smarter and more complex, the fire safety tips that protected buildings a decade ago simply aren’t enough anymore.

According to the National Fire Protection Association (NFPA), structure fires cause billions of dollars in property damage annually, and a significant share of those losses occur in commercial and industrial facilities. The difference between a near-miss and a catastrophe increasingly depends on how early a fire is detected and how intelligently a building responds to that detection.

This guide brings together the most practical, forward-thinking fire safety tips for facility managers navigating the AI era.

Why AI Fire Detection Is Essential for Modern Facilities

Traditional fire alarms detect smoke or heat after a fire has already established itself. AI fire detection systems operate differently; they continuously analyze environmental data, identify patterns, and flag anomalies long before a flame takes hold.

Modern facilities are not simple spaces. They house battery storage systems, high-density server racks, chemical processing lines, and complex HVAC networks, all of which introduce fire risks that conventional detectors weren’t designed to handle. Intelligent fire monitoring addresses exactly this gap by processing multiple data streams simultaneously, from temperature gradients to gas concentration levels, using machine learning to separate real threats from background noise.

The global AI in fire safety market is expected to grow significantly through 2026 and beyond, driven by stricter building codes, insurance requirements, and the widespread adoption of IoT infrastructure. For facility managers, the key fire safety tip here is straightforward: if your detection infrastructure hasn’t been reviewed in the past three years, it is likely behind where it needs to be.

Explore how fire detection systems are evolving to meet these demands in practice.

Fire Safety Tips for Smart Building Risks

Smart buildings introduce a new category of fire risk that most standard protocols don’t account for. Connected HVAC systems, automated lighting rigs, and IoT-enabled equipment all generate heat, draw power, and interact in ways that can exacerbate fire conditions.

Here are targeted fire safety tips specifically for smart building environments:

1. Audit your power infrastructure regularly: Lithium-ion battery banks and EV charging stations are among the fastest-growing fire risk factors in commercial facilities. These require specialized detection, as they can undergo thermal runaway, a rapid, self-sustaining heating process without producing visible smoke in the early stages.

2. Integrate your fire detection with your building management system (BMS): When smart fire prevention systems communicate directly with HVAC controls, they can shut down air-handling units that might otherwise spread smoke through the ductwork during an event.

3. Map your dead zones: Smart buildings often include cable risers, roof plant rooms, and raised-floor voids, which teams routinely miss when placing detectors. A physical walkthrough with your fire safety consultant should map every space, not just occupied ones.

4. Train staff on automated emergency response systems: Technology is only as effective as the people supporting it. Staff should understand what automated alerts mean, how to verify them, and what manual override procedures look like.

5. Review your fire safety documentation annually: Fire risk assessments in smart buildings should be dynamic documents, updated every time a new system is installed or the building’s use changes significantly.

How AI Smoke Detection Improves Emergency Response

Speed is everything in fire response. Every additional second between ignition and alarm activation increases the risk to life and the likely extent of property damage. Real-time smoke detection powered by AI dramatically compresses this response window.

Traditional photoelectric smoke detectors respond to the physical presence of particulates. AI-driven systems go further; they use video analytics, chemical sensors, and pattern-recognition algorithms to identify the signature of combustion at microscopic concentrations. Some systems deployed in 2025 and 2026 can detect the early byproducts of smoldering fires, such as carbon monoxide and volatile organic compounds, up to 30 minutes before visible smoke appears, according to research highlighted by Eurofins Scientific.

This capability transforms emergency response in two important ways. First, it allows building systems to pre-position resources, unlock stairwells, alert on-site security, and notify fire services before conditions become dangerous. Second, it gives occupants more time to evacuate calmly rather than in a panic, thereby reducing injury risk.

Pairing real-time smoke detection with smart systems for fire monitoring ensures your response protocols are as up to date as your detection hardware.

Fire Safety Tips Using Thermal Imaging and Smart Sensors

Thermal anomaly detection is arguably the most transformative technology currently entering mainstream facility fire safety. Unlike smoke or heat detectors, which are reactive, thermal cameras and smart sensors continuously scan for temperature anomalies that indicate electrical stress, overheating equipment, or friction-generated heat.

Here are fire safety tips for implementing thermal and sensor-based detection effectively:

1. Install thermal cameras at high-risk equipment zones: Electrical switchgear, transformer rooms, and battery storage areas benefit most from continuous thermal monitoring. A temperature spike of even 10–15°C above baseline on a specific component is an actionable warning long before failure occurs.

2. Use multi-sensor fusion: The most accurate detection systems combine thermal imaging with gas sensors, acoustic sensors, and optical smoke detectors. Cross-referencing data from multiple inputs dramatically reduces both missed detections and false alarms.

3. Set graduated alert thresholds: Not every thermal anomaly is an emergency. Well-configured predictive fire analytics systems can categorize alerts by severity, flagging a maintenance issue at level one and triggering a full evacuation protocol only when multiple parameters align.

4. Ensure regular sensor calibration: Smart sensors drift over time. Build a calibration schedule into your preventive maintenance program, particularly for detectors in environments with wide temperature swings or chemical exposure.

5. Document baseline conditions: AI systems learn from historical data. Feeding your system accurate baseline readings from commissioning onwards makes its anomaly detection progressively more precise.

The NFPA 72 standard on fire alarm and signaling systems provides a useful framework for understanding how sensor placement and system design requirements are evolving to accommodate these new technologies.

Protecting Critical Infrastructure with Intelligent Fire Monitoring

Data centers, utilities, healthcare facilities, and transport hubs represent high-consequence environments where a fire doesn’t just threaten a building; it threatens the services and communities that depend on it. Intelligent fire monitoring is becoming a compliance expectation, not just a best-practice recommendation, in many of these sectors.

For critical infrastructure operators, facility fire risk management should include:

  • Zone-based suppression integration: Suppression systems should be able to isolate and address a fire within a defined zone without contaminating adjacent clean rooms, server halls, or patient areas.
  • Redundant detection pathways: No single point of failure should disable your entire detection network. Industrial fire safety solutions designed for critical environments build redundancy at both the hardware and software levels.
  • Regular tabletop and live-fire drills: Technology does not replace procedural competency. Drills that test both the automated systems and the human response remain a non-negotiable component of any credible fire safety program.
  • 24/7 remote monitoring partnerships: Many critical facilities now contract with connected fire protection platforms that provide around-the-clock monitoring, remote diagnostics, and rapid escalation services.

This level of sophistication in facility fire risk management is not exclusive to large operators. Even mid-size facilities handling high-value or sensitive assets should be moving in this direction.

How Machine Learning Reduces False Fire Alarms

False alarms are not merely inconvenient; they are genuinely dangerous. They fatigue staff, desensitize occupants to alerts, and consume fire service resources that may be needed elsewhere. According to London Fire Brigade data, a substantial proportion of emergency call-outs are false or unwanted fire signal activations, a problem that is common across major urban fire services globally.

Machine learning addresses this problem through contextual intelligence. Where a traditional detector simply measures whether smoke particles exceed a threshold, an ML-trained system evaluates the entire environmental context, time of day, recent activity in the zone, humidity, temperature history, and the behavior of adjacent sensors before triggering an alarm.

False fire alarm reduction is one of the most compelling operational arguments for upgrading to AI-driven detection. Facilities that have made the switch report significant reductions in unwanted alarm activations while maintaining or improving their true detection rates.

The practical fire safety tip here is that when evaluating any new detection system, ask vendors specifically for their false-alarm discrimination performance data, not just their sensitivity specifications. Both numbers matter equally.

Future Fire Safety Tips Using Predictive Automation

The near-term future of fire safety sits at the intersection of predictive fire analytics, autonomous building systems, and real-time data integration. Facilities that invest in this direction now will be meaningfully ahead of both regulation and risk in the years to come.

Key fire safety tips for building a future-ready program:

1. Move from reactive to predictive: The goal of a modern fire safety strategy is to intervene at the pre-fire stage, addressing the conditions that lead to fire before they escalate. Predictive fire analytics tied to equipment health monitoring enables exactly this outcome.

2. Connect fire safety data to your broader risk management platform: Fire incidents don’t exist in isolation. When you integrate your fire safety data with your operational risk dashboard, you give leadership a clearer picture of where vulnerabilities exist and where to direct resources.

3. Invest in fire safety automation: Automated suppression, smoke control, and evacuation systems reduce response times and remove the variability of human reaction under stress.

4. Stay ahead of evolving standards: Codes and standards around AI-enabled fire detection are actively being developed. Engaging with future fire safety technologies now positions your organization to meet those standards ahead of mandatory deadlines.

5. Budget for ongoing system evolution: AI fire detection systems are software-driven, which means they can improve over time through updates. Treat your fire safety infrastructure as a living system, not a one-time capital investment.

Conclusion

The AI fire detection boom is not coming; it is already here, reshaping what best-practice fire safety looks like for facilities of every size and across sectors. The fire safety tips covered in this guide reflect a clear direction of travel: from reactive to predictive, from single-sensor to multi-system, from periodic inspection to continuous intelligent monitoring.

Facility managers who act on these fire safety tips, now auditing their current infrastructure, integrating smart detection, reducing false alarms, and building toward predictive automation, will be better protected, better insured, and better positioned for the regulatory landscape ahead.

Fire safety has always been about protecting lives. In 2026, the tools available for that purpose are more sophisticated than ever. The responsibility is to use them.

FAQs

What are the best fire safety tips using AI detection? 

The most impactful fire safety tips for AI detection focus on multi-sensor integration, thermal anomaly monitoring, real-time data analytics, and automated emergency response. Start by auditing your current detection infrastructure against the specific fire risks in your facility, then layer in AI-driven tools where coverage gaps exist.

How does AI improve modern fire safety tips? 

AI improves fire safety by enabling predictive detection rather than reactive response. Machine learning algorithms continuously analyze environmental data to identify the early signatures of fire development, often 20–30 minutes before visible smoke, giving facilities more time to respond safely and effectively.

Why is AI monitoring important for fire safety tips? 

AI monitoring is important because modern facilities are too complex and too interconnected for conventional detection systems to manage alone. Intelligent fire monitoring processes multiple data streams simultaneously and applies contextual reasoning, dramatically improving both detection accuracy and response speed.

Can AI reduce false alarms with smarter fire safety tips? 

Yes. False alarm reduction is one of the strongest proven benefits of AI-driven detection. Machine learning systems evaluate the full environmental context before triggering alerts, which eliminates most unwanted activations caused by steam, cooking, dust, or humidity issues that routinely defeat traditional threshold-based detectors.

What fire safety tips help protect smart facilities? 

Smart facilities need fire safety tips that account for their specific risks: lithium-ion battery storage, EV charging infrastructure, high-density electrical distribution, and IoT device proliferation. Integrate fire detection with the building management system, use thermal imaging in high-risk zones, and ensure your risk assessments are updated whenever new systems are installed.

How does thermal imaging support fire safety tips? 

Thermal imaging supports fire safety tips by detecting temperature anomalies in equipment and infrastructure long before they reach the ignition point. Continuous thermal monitoring of electrical switchgear, server racks, and battery systems enables maintenance teams to address overheating conditions proactively, removing the hazard before it can cause a fire.

Siemens launches cloud-connected fire detectors for autonomous building operations

Siemens fire detector launch in Zug

Siemens has unveiled its Sinteso Nova and Cerberus Nova fire detector portfolio in Zug on 27 March 2026, introducing a cloud-connected fire safety system designed for continuous monitoring.

The company said the detectors use IoT connectivity to support 24/7 self-checks, real-time monitoring, remote diagnostics and predictive maintenance across building environments.

The portfolio is designed for sectors including healthcare, higher education, data centres and commercial real estate.

It is also compatible with cloud-based applications such as Siemens’ Building X Fire Apps.

Siemens outlines detection technology and applications

Siemens said healthcare facilities can use the detectors for continuous supervision, with Disturbance-Free Testing (DFT) carrying out automated self-checks to reduce system downtime.

Smoke Entry Supervision (SES) monitors smoke entry points in real time, enabling earlier intervention when risks develop.

ASAplus combines multi-wavelength optical sensing with dual thermal detection to reduce false alarms and limit unnecessary evacuations.

In data centres, the detectors are intended to support operational continuity where overheating and electrical faults present fire risks.

For higher education and commercial real estate, the systems are designed to support centralised management across multiple sites through continuous monitoring and maintenance planning.

Upgrade approach and Siemens statement

Siemens said the detectors support stepwise upgrades in both new and existing buildings, with compatibility retained for existing fire panels.

The company said plug-and-play integration includes automatic transfer of configured settings, reducing installation time and associated risk.

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,”

Siemens said the detectors carry its EcoTech environmental product performance label, use recycled plastics and form part of the Siemens Xcelerator portfolio developed and produced in Switzerland.

Two Bulgarian installations highlight Hochiki fire detection range

Hochiki projects in Bulgaria

Hochiki Europe has published details of two completed fire detection installations in Bulgaria, covering a logistics warehouse in Radinovo and a mixed-use tower in Sofia.

The company said the projects were delivered by partners MCM Engineering and Sectron, using different parts of the Hochiki product range to match each building’s layout and fire detection needs.

At the BULTEX 99 logistics centre in Radinovo, a 270,000 square foot facility storing large volumes of flammable clothing materials, MCM Engineering installed 350 ESP intelligent devices with Hochiki’s 6-loop Latitude fire control panel.

The site’s dense racking storage systems were protected using FIREbeam Xtra addressable beam smoke detectors positioned along warehouse corridors.

Georgi Georgiev said: “Hochiki’s ESP open protocol gives us the flexibility when dealing with such a large and complex facility, BULTEX 99 now have a centralised system that is simple to monitor and designed to support future expansion.”

Smart Tower installation in Sofia

In Sofia, Hochiki Europe said Sectron completed an installation at Smart Tower, a development with 30 floors of luxury apartments, 12 levels of commercial space and a four-storey underground car park.

The estimated occupancy across the two connected buildings is 2,552.

More than 10,000 Hochiki devices were installed across the development.

The commercial areas used the ESP addressable range, individual apartments used the Conventional CDX range and the basement car park used Hochiki’s Linear Heat Detection Cable where exhaust fumes made conventional smoke detection unsuitable.

Elena Pencheva, Design Engineer, Sectron, said: “Hochiki’s multiple solutions made overcoming the challenges with Smart Tower’s infrastructure straightforward.

“The open-protocol capabilities provided ultimate flexibility when integrating multiple, tailored solutions across the building.”

The two installations were presented as examples of how different Hochiki systems can be applied across large warehouse and mixed-use residential developments.

Fire and smoke detection results raise questions for smart cities

Detection system combines two AI models

Researchers at Jouf University in Saudi Arabia have developed an artificial intelligence framework for early smoke and fire detection in smart city environments.

A study by Amr Abozeid and Rayan Alanazi describes a hybrid system that combines a Vision Transformer with the YOLOv8 object detection architecture.

The framework is designed to identify early-stage smoke and fire patterns in complex visual scenes and support faster response through smart city monitoring systems.

The study says conventional heat and smoke detectors often raise alerts only after smoke reaches the device.

It adds that existing video-based systems can also produce false alarms when visual conditions include dust, clouds or changes in lighting.

The Vision Transformer analyses global visual patterns in an image so the system can detect subtle smoke characteristics and spatial relationships across a scene.

The YOLOv8 module then performs real-time object detection to localise smoke and fire regions at speed.

Detection results and next steps

According to the study in Scientific Reports, the researchers trained and tested the model on more than 7,000 images from urban and rural datasets.

These images included smoke and fire scenes captured under different lighting conditions and in different environments.

The system achieved 99.2% accuracy, with precision of 98.5% and recall of 97.8%.

Its F1 score reached 98.1% and inference latency was about 45 milliseconds, which the study says enabled real-time detection at about 22 frames per second.

The researchers reported an accuracy increase of about 4.3% compared with conventional convolutional neural network approaches and other single-model detection systems.

The study also says the framework performed better than several existing detection models across precision, recall and localisation accuracy.

It states that the hybrid architecture can distinguish real smoke or fire from visually similar features such as printed flames or static images by analysing contextual and spatial characteristics rather than relying only on colour.

The authors say further validation in real-world settings is still needed, with future work set to examine thermal imaging and environmental sensor inputs for low-visibility conditions.

Gutteridge has been in his new role for around six months, having previously been Siemens Solutions Partner Manager for the UK and Ireland for the company’s digital industries business.

Completing the line-up is Marios Malone as RSM for fire in the South.

Malone has more than 20 years of experience in the fire safety industry, including three years with Siemens.

Robert Yates, Head of Building Products Fire Safety in the UK, said: “It is a very exciting time for the business with the use of digitalisation in our offering.

“It was important for us to have a strong team in place to support our partners and to maximise the opportunities this presents in the market.

“We have recruited from within Siemens, drawing not only on the understanding of how the company operates but also from those who have direct experience of working within the fire safety arena.”

Hochiki installs bespoke detection system at Willis Aviation’s Teesside base

Hochiki case study at Teesside International Airport

A bespoke fire detection solution from Hochiki Europe has been installed at Willis Aviation Services’ maintenance base at Teesside International Airport, covering Hangars 7 and 8 across 45,000 m².

Hochiki said the project was delivered with local life-safety specialist Render Alarms, which designed and installed a tailored system built around Hochiki intelligent detection technology.

The site includes hangars, workshops and office space.

The case study described engineers working with high-value aircraft and potentially flammable materials.

System design and devices specified

The installation centres on Hochiki’s ESP intelligent fire detection system, described as offering open-protocol flexibility and performance aligned with the forthcoming BS 5839-1 2025 standard.

In office environments, adjustable smoke and heat detectors were specified, described as supporting reliable detection and reducing unwanted alarms.

In workshop areas, wall-mounted sounder beacons were installed to provide visual alerts in high-noise conditions.

For hangar voids, Hochiki’s FIRElink aspirating detection system was specified, described as using laser-based technology to monitor large areas with enhanced sensitivity and reduced maintenance requirements.

Render Alarms’ installation team used specialist design software to optimise the aspirating pipe network around the hangar’s structural framework, with the case study describing this as supporting coverage and compliance.

Luke Render, from Render Alarms, commented: “Hochiki’s bases are a gamechanger, one base fit all devices.”

The case study described sensors twist-fitting onto bases as part of the installation and commissioning approach.

Euralarm fact sheet explains Cyber Resilience Act product classification for fire safety manufacturers

Euralarm fact sheet on CRA categories

A new fact sheet sets out how electronic fire safety and security products are classified under the EU Cyber Resilience Act (CRA), published in November 2024.

Euralarm said the document is intended to help manufacturers understand categorisation and conformity assessment obligations before products can be placed on the EU market.

The fact sheet describes the CRA product categories as “default,” Important Class I, Important Class II, and Critical.

It explains that the essential cybersecurity requirements apply equally to all in-scope products with digital elements.

It also explains that Important and Critical products are subject to stricter conformity assessment procedures.

The document sets out why correct categorisation matters for deciding whether self-assessment is permitted or whether a notified body is required.

Examples used to classify fire safety and security products

In the fact sheet, Euralarm provides structured examples focused on electronic fire safety and security products where interpretation can raise practical questions.

The examples include smart home products with security functionalities, identity management systems and privileged access management products, and hardware devices with security boxes.

The document also uses examples including intrusion detection systems, fire detection control panels, access control systems, biometric readers, and cloud-based alarm management software.

It explains when a product’s core functionality determines its categorisation.

It states that most electronic fire safety and physical security products are expected to fall within the “default” category and may rely on self-assessment where compliance with the CRA essential requirements can be demonstrated.

It also states that embedding security-related components such as microcontrollers with security functions or cryptographic capabilities does not automatically make a product “Important” or “Critical” where its core functionality does not meet the criteria defined in the Implementing Regulation.

Standards and conformity assessment routes

Euralarm noted that future harmonised standards under development may support manufacturers in demonstrating conformity under the CRA.

The fact sheet references EN 62443-4-x and other horizontal standards as examples that may support presumption of conformity where applicable.

The publication is presented as part of Euralarm’s ongoing work to support the fire safety and security industry in adapting to European regulatory requirements.
