TH68N Digital LHD Nylon Cable 68°C/155°F 100m Drum

TH68N Digital Linear Heat Detection Nylon Cable – 68°C / 155°F Alarm Temperature – 100m Drum

The TH68N Digital Linear Heat Detection (LHD) Cable is a robust, high-performance solution designed for early fire detection in a wide range of industrial, commercial, and hazardous environments. With a fixed alarm temperature of 68°C (155°F) and supplied in a 100-metre drum, this UL 521-approved nylon-coated cable delivers precise and reliable overheat detection where traditional smoke detection is ineffective.

Manufactured with twisted tri-metallic conductors and advanced temperature-sensitive polymer insulation, the TH68N cable activates an alarm the moment its temperature threshold is reached, triggering a dependable response through your fire alarm control panel. Its nylon outer sheath offers exceptional UV resistance, abrasion resistance, and chemical protection, making it especially suitable for harsh or outdoor environments and where hydrocarbons like diesel, kerosene, and fuel oils are present.

Ideal for use in tunnels, cable trays, warehousing, escalators, and transport infrastructure, this cable can be connected directly to conventional fire systems or integrated with addressable systems via a zone/switch monitor, offering both versatility and ease of installation.
