Programmable Temperature Sensing (Resettable)
Thermocable’s Programmable Temperature Sensing Linear Heat Detection (previously known as ‘analogue’) is a cable-based fire detection solution that combines over 60 years of fire safety expertise with innovative technology that adapts to the most demanding environments.
Unlike conventional spot detectors, Programmable LHD’s four-core cable continuously monitors resistance changes along its length, allowing for precise temperature tracking and early warning capabilities. It’s ideal for environments where gradual temperature changes or rate-of-rise scenarios are common — such as tunnels, car parks, and solar PV installations.
Why Choose Programmable LHD?
- Resettable detection
the system can be reset after an alarm event (unless the thermal limit is exceeded), reducing cable replacement costs. - Ambient temperature compensation
minimises false alarms in environments with fluctuating conditions such as solar farms or refrigerated facilities. - Programmable alarm thresholds
configurable alarm and pre-alarm settings to match specific risks, from low-temperature areas to high-heat industrial zones. - Flexible installation
cable-based design provides continuous coverage in hard-to-reach areas where point detectors fail.

Applications Across Critical Sectors
Programmable LHD is engineered for industries where traditional detectors fall short:
- Industrial
dependable fire protection for production plants and transformer bays, where machinery generate different heat levels and downtime is costly. - Infrastructure
continuous coverage for tunnels, car parks, and cable trays, where long cable runs and harsh conditions make point detectors impractical. - Data Centres
protecting equipment from costly outages by detecting early signs of overheating. - Warehousing & Cold Storage
flexible thresholds adapt to low ambient conditions, preventing false alarms while ensuring rapid response in temperature-sensitive storage.
Built for Distributors, Specifiers, and Operators
- For distributors, it’s a clear differentiator in the market: resettable, programmable, and internationally approved. Easy to explain, easy to sell.
- For fire safety engineers, it’s a product that adds to their portfolio which integrates seamlessly into complex fire detection systems.
- For facility managers, it’s dependable coverage that keeps operations running without costly false alarms or downtime.
