Fire Detection for Sub-Zero, High-Consequence Cold Storage Environments
Cold storage facilities operate under extreme, tightly controlled conditions designed to protect temperature-sensitive goods. However, these same conditions introduce distinct fire detection challenges that must be considered at the design stage.
Sub-zero temperatures, concealed ignition points within high-bay racking, insulated construction and continuous airflow can all interfere with conventional detection technologies, increasing the potential impact of a fire event.
ProReact Linear Heat Detection (LHD) is purpose-engineered to perform reliably in freezing environments, providing continuous temperature sensing and offering dependable early warning across cold storage facilities where traditional systems may struggle.

Why Fire Detection Must Be Approached Differently in Cold Storage
- Concealed ignition within high-bay racking and panels
Dense racking systems and insulated sandwich panels can hide early ignition, allowing fires to develop within enclosed or inaccessible spaces before heat or smoke reaches traditional detectors. - Fire risk from plant, automation, and continuous operation
Refrigeration plant rooms, electrical switchgear, conveyors, and automated handling systems introduce persistent overheating and ignition risks, often in areas with limited occupancy and supervision. - Sub-zero conditions that impair conventional detectors
Freezing temperatures, condensation, and ice formation can reduce sensor sensitivity, cause component failure, or increase nuisance alarms in point-type smoke and heat detectors. - Airflow and stratification that delay alarm activation
High air circulation from evaporator fans and temperature layering can disperse or trap heat and smoke, preventing ceiling-mounted detectors from activating until a fire is already well developed.

- Detection at the source, not the ceiling
ProReact Linear Heat Detection provides continuous sensing along the entire cable length, allowing fires to detected close to likely ignition points within racking, plant rooms, and sandwich panels. - Reliable performance in extreme low temperatures
Purpose-engineered for cold storage, ProReact LHD maintains dependable operation in sub-zero environments, including temperatures as low as -60°C, where conventional detectors may degrade or fail. - Unaffected by airflow, condensation, or stratification
As a heat-based detection system, ProReact does not rely on smoke movement, making it well suited to freezer environments with high airflow and disrupted fire behaviour. - Adaptive protection with programmable alarm response
The ProReact Programmable range offers programmable alarm thresholds and optional rate-of-rise detection, supporting faster response to rapid temperature increases while helping to minimise false alarms in sensitive cold storage operations.

Installation Best Practices for Cold Storage
- Install LHD to follow the racking layout, running along aisles and across storage zones to provide coverage of critical risk areas and concealed ignition points.
- Account for sub-zero conditions by maintaining appropriate cable support, regular fixed intervals, and a minimum bend radius of 150 mm (6 inches) to protect long-term performance.
- Use mounting accessories suitable for freezing environments i.e., silicone sleeves, and locate controllers and interface modules outside cold areas to avoid condensation and extreme temperature exposure.
