Linear Heat Detection Cables (LHDC)

Simple Installation, High Sensitivity, Early Detection
Honeywell’s Linear Heat Detection Cable (LHDC) is a continuous heat detector that can detect heat (due to fire or other events) at any point along its entire length. The cable is composed of two twisted-shield conductors, insulated with a heat-sensitive polymer, then wrapped with a protective tape and finished with an outer covering.

Analogue/Resettable LHDC

Honeywell’s Analogue LHDC consists of insulators whose resistance varies proportionally to changes in temperature. This cable is self-restorable after the fire event as long as temperature does not exceed its specified resettable temperature limit of 120°C.

Feature
  • Construction: overall insulated, twisted pair of tri-metallic cores
  • Insulation: 1kV tested protective outer coat
  • Multiple alarm temperature ratings
  • Maximum zone length: 200 metres
  • Compatible with any conventional or intelligent fire alarm panel
  • Smoothing algorithms provide false alarm immunity
  • Approvals: CE Marked, RoHS Compliant, FM, UL

Digital/Non-Resettable LHDC

The Digital LHDC from Honeywell is a fixed-temperature, non-resettable cable from Honeywell, the worldwide leader in fire safety solutions. Each cable consists of low-resistance, twisted-pair, tri-metallic conductors, sheathed in thermal polymers that are chemically engineered to break down at specific fixed temperatures.

Feature
  • Construction: overall insulated, twisted pair of tri-metallic cores
  • Insulation: 1kV tested protective outer coat
  • Multiple alarm temperature ratings
  • Maximum zone length: 3000 metres
  • Compatible with any conventional or intelligent fire alarm panel
  • Smoothing algorithms provide false alarm immunity
  • Approvals: CE Marked, RoHS Compliant, FM, UL
