ProReact Linear Heat Detection for Road and Access Tunnels
Protecting Lives and Infrastructure in the Harshest Tunnel Environments.
Road and access tunnels present some of the most demanding conditions for fire detection. Dampness, humidity, dust, and limited airflow make traditional point detection systems unreliable and difficult to maintain. Fires in these environments can escalate rapidly, threatening lives, disrupting transport, and causing extensive damage.
ProReact Linear Heat Detection (LHD) is engineered to thrive where other systems fail. Designed for continuous coverage and minimal maintenance, our cable-based detection technology offers a robust, reliable solution for tunnel safety.

Why Tunnel Fire Detection is so Challenging
- Harsh Conditions
High humidity, dust, and debris interfere with conventional sensors. - Limited Access
Maintenance and visual inspections are difficult and costly. - Rapid Fire Spread
Fires in enclosed tunnel spaces can intensify quickly, requiring fast and accurate detection. - False Alarms
Environmental factors often trigger false positives in traditional systems, leading to unnecessary disruptions.
How ProReact LHD Solves Challenges in Road & Access Tunnels
- Resilient in Harsh Environments
Unaffected by dirt, dust, and moisture, ProReact cables are built to last and perform reliably over time. - Continuous Coverage
Installed along tunnel ceilings or walls, LHD provides uninterrupted detection across long distances. - Pinpoint Accuracy
Optional Alarm Point Distance Locator helps identify the exact location of an incident for faster response. - Low Maintenance
Often described as “fit and forget,” ProReact systems require minimal upkeep and are designed for decades of service. - Flexible Activation Options
Choose from fixed temperature cables (non-resettable) or programmable sensing cables (resettable), depending on your tunnel’s needs.
