Linear Heat Cable

Linear Heat Detection Cable

Product Overview

Linear Heat Detection Cable (LHD) is designed for use where traditional point heat detectors are unsuitable. LHD is a fixed temperature sensor capable of initiating an alarm once its rated temperature has been exceeded. It consists of two tri-metallic conductors twisted together to keep them under mechanical tension. Each conductor is individually coated with a temperature-sensitive polymer that detects heat conditions anywhere along its length. It is not required that a specific length be heated in order to initiate an alarm. Linear heat detection cable provides the advantage of line coverage with point sensitivity.


  • Suitable for use with Pertronic NZS 4512:2010 conventional zones of Loop Responder, Apartment Module, F16e, F4 and F1
  • Simple installation using standard 10 kΩ EOL resistor and one alarm resistor in series with the LHD cable
  • Can be used for Hazardous areas with Galvanic Isolator
  • Available: 200 m and 500 m drums
  • Maximum Zone Length: 3,000 m
  • International Approvals: CE marked, RoHS compliant, UL, FM, GOST-R
