Reliable, Fast-Response Heat Detection for Critical Applications

When fast, fixed-temperature fire detection is vital, Patol’s digital linear heat detection cable delivers exceptional performance with proven reliability.

Designed for early detection of overheating and fires along long distances, our non-resettable heat detection cables provide immediate alerts the moment a specified temperature is reached—helping protect critical infrastructure where delays are not an option.

From tunnels and conveyors to power stations and car parks, Patol’s digital cable systems are trusted in environments where fast, simple fire detection is essential.

How Digital Linear Heat Detection Cables Work

Digital linear heat detection cables are constructed with two specially coated conductors separated by a heat-sensitive polymer.

Under normal conditions, the cable remains open and inactive.

When the cable is exposed to a specific temperature (for example, 70°C, 90°C & 180° etc.), the heat melts the polymer, allowing the conductors to come into contact and trigger an alarm.

Once activated, the affected portion of the cable must be replaced (hence, "non-resettable").

Applications of Digital Linear Heat Detection

• Conveyor belt fire protection
• Cable tunnels and risers
• Storage tank and fuel depot monitoring
• Car parks and underground structures
• Power generation facilities
• Industrial manufacturing sites

Wherever a straightforward, durable, and fast-acting heat detection solution is needed, Patol’s non-resettable cables provide trusted protection.
