Linesense H9650
LINEAR HEAT DETECTION (LHD)
(240°C, 464°F Nominal)

The technology behind the digital Linear Heat Detection (LHD) cable, makes it suitable for difficult and challenging applications where other technologies struggle to work.

The cable is easy to install and maintain. It also provides a cost effective solution where project expenditure requires this to be kept at a minumum.

The sensing cable is created from a pair of twisted steel conductors, each with their own temperature sensitive insulation. This then has an overall Fluropolymer outer sleeve. When the temperature sensitive insulation reaches it's predetermined alarm temperature the two conductors short together providing the digital or switched signal.

The cable can be connected to any unit capable of monitoring a switched signal, i.e. Conventional fire panel, addressable switch monitor unit or PLC.

Linesense H9650 Digital LHD

The Fluropolymer outer sleeve of the Linesense H9650 offers exelent chemical and water resistance, allowing it to be deployed in harsh and dirty environments.

Features

  • Simple digital switch operation.
  • Continuous sensing along the total length of the element.
  • Fixed alarm temperature operation.
  • Compatible with switch monitoring units and conventional alarm panels.
  • Suitable for use in Hazardous areas using safety barriers.
  • Chemical & water resistant Flouropolymer outer sleeve.
  • Rugged and durable construction.
  • Simple maintenance free installation.
  • Small diameter and bend radius.
  • FM Approved.
