Linesense H8045N
LINEAR HEAT DETECTION (LHD)
(85°C, 185°F Nominal)

The technology behind the Linear Heat Detection (LHD) cable is proven and simple, making it a product of choice for difficult and challenging applications where other technologies may struggle.

It is easy to install, with low maintenance therefore making it a cost effective solution where project expenditure requires to be kept at a minumum.

The sensing cable is created from a two twisted steel conductors, with temperature sensitive insulation on each conductor. The cable has an overall Nylon 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 connect to any unit capable of monitoring a switched signal, i.e. Conventional fire panel, addressable switch monitor unit or PLC.

H8045N Digital LHD Cabling

The outer sleeve of the Linesense H8045N is nylon which offers chemical and water resistance, so the cable can be used in harsh dirty environments.

Features

  • Digital switch operation.
  • Continuous sensing along the length of the element.
  • Fixed alarm temperature operation.
  • Switch monitoring unit and conventional alarm panel compatible.
  • Can be used in Hazardous areas using safety barriers.
  • Rilson outer sleeve that is chemical & water resistant.
  • Rugged and durable construction.
  • Maintenance free, simple installation.
  • Small diameter and bend radius.
  • FM Approved.
