Patol Managing Director Iain Cumner explains how advanced detection solutions improve warehouse safety, compliance, and performance across automated, high-bay environments
Warehousing is changing.
Facilities today are taller, denser, and increasingly automated – designed to support the pace of modern 24/7 supply chains.
For site and facilities managers, the stakes are high.
Delays in fire detection don’t just mean lost stock – they put staff at risk, halt operations, and can damage hard-won reputations.
Let’s face it – cost continues to drive fire detection decisions.
But with UK insurers and regulators raising the bar on compliance, including BS 5839-1, the right solution now matters more than ever.
The challenges of modern warehousing height & stratification
In high-rack warehouses, there are specific areas that make conventional detectors less effective:
- Height & smoke layering: In tall warehouses, smoke can form layers (known as stratification) rather than rising to ceiling-mounted detectors, delaying alarms.
- Air movement: Ventilation, fans, or conveyor systems can push smoke away from detectors, while dense racking and tight packing of stock can prevent smoke reaching detectors.
- Access issues: In high racks or automated storage systems, installing and maintaining detectors is expensive and disruptive.
- Special environments: Cold storage, dusty sites, and humidity add further complications – from frozen detectors to false alarms.
- Even subtle fluctuations in temperature can interfere with detectors.
-
The result? Increased downtime, costly false activations, and risk of non-compliance.
These factors make one thing clear: conventional approaches to fire detection are unable to keep up with the demands of modern warehouses.
Modern Detection Technologies
Aspirating Smoke Detection (ASD)
Once considered unsuitable for dusty or industrial environments, ASDs have evolved to be ultra-sensitive and are now considered to be far more suitable for application that traditional point detection:
- Continuously samples air through a network of pipes, providing very early smoke detection.
- Modern systems now feature in-line blow-out filters and dust purge technology, addressing the false alarm problems that gave aspirators a poor reputation in the past.
Benefit for managers: Fewer false alarms, less maintenance, and earlier warnings – giving more time to act without disrupting daily operations.
Linear Heat Detection (LHD)
LHD offers a straightforward, yet effective solution:
- Uses heat-sensitive cable that triggers when a set temperature is reached.
- Ideal for racking aisles, conveyor belts, and hard-to-reach areas.
Benefit for managers: Works reliably regardless of airflow, reducing the risk of delayed detection and avoiding costly downtime.
Together, LHD and ASD complement each other, offering detection solutions that adapt to the requirements of today’s warehousing rather than forcing the environment to adapt to the technology.
Expert Insight
Patol’s Managing Director, Iain Cumner, highlights that the conversation around warehouse fire protection has shifted dramatically in recent years: “The days of exclusively relying on ceiling-mounted point detectors in warehouses are over.
With facilities now exceeding 20 metres in height, filled with dense racking, and incorporating complex automation, we need detection solutions that can ‘think differently’.
“Linear Heat Detection and Aspirating Smoke Detection are not just technologies.
“They’re enablers of safer, more resilient facilities. But the key is expertise.
“It’s about matching the right product to the right environment, and designing systems that balance compliance with practicality.”
This people-first, consultative approach is at the heart of Patol’s value proposition.
Trusted fire detection solutions are not just about products but about ensuring safety and continuity for people, businesses, and communities.
Practical advice for consultants and specifiers
When planning or upgrading fire detection in warehouses, keep these points in mind:
- Think in zones: Break large spaces into detection zones to quickly identify where a fire starts and limit unnecessary disruption.
- Match the tech to the risk: Use LHD for conveyors and racking; ASD for high-value stock or areas where early detection is essential.
- Plan maintenance early: Choose designs that allow servicing without major operational downtime.
- Work with experts: Engage with fire detection specialists early in the design stage to ensure compliance with BS 5839-1, BS EN54-22 and BS EN54-28 and alignment with insurer requirements.
What is the future of warehouse fire detection?
Automation, robotics, and AI-driven logistics will demand fire protection strategies that are adaptive and intelligent.
We will see more integration between detection and smart building management systems, enabling real-time analytics and predictive maintenance.
Hybrid systems that combine LHD, ASD, and intelligent control will become standard, providing a layered approach to protection.
At the same time, the emphasis on sustainability will grow – with detection systems designed to reduce energy use, minimise maintenance visits, and extend equipment lifespan.
Yet the core principle remains the same: protecting people.
Warehouses are workplaces as much as they are storage facilities.
Fire safety is about safeguarding employees, first responders, and the communities that rely on these essential buildings.
Fire safety in warehouses is about more than technology – it’s about confidence.
Confidence that your site is protected.
Confidence that operations won’t be disrupted by false alarms.
Confidence that your system meets both UK standards and insurer expectations.
Throughout this transition, Patol’s role is to delivers trusted fire detection solutions for challenging environments, combining technical expertise, responsive service, and a people-first approach.
With certified products, rapid dispatch, and ongoing consultancy, we help facilities managers achieve not only compliance but also the peace of mind that comes from knowing both people and assets are safe.
Case Study: Protecting Portcentric Logistics, Felixstowe
At the Port of Felixstowe, PD Portcentric Logistics operates one of the UK’s largest customs-approved warehousing facilities, storing a wide range of goods from fast-moving consumer products to ambient foodstuffs.
With three high-bay warehouses and racking exceeding 20 metres, ensuring reliable fire detection was a significant challenge.
Patol supplied 24 ASD units, installed by BBC Fire Protection (part of Marlowe plc), to provide comprehensive coverage across the site.
A mix of compact and two-channel detectors ensured every zone, from small ambient storage areas to large high-level bays was effectively protected.
By locating the ASD sampling points at accessible low levels, the system offered fast, reliable detection without disrupting operations.
The design also reduced maintenance complexity and downtime, as detectors could be serviced without specialist access equipment.
For the site’s management team, the result was clear: enhanced protection, simpler compliance, and complete peace of mind that both people and products are safeguarded around the clock.
This case demonstrates how modern detection, applied with expertise, can overcome problems that traditional systems would fail to address.
