H8028 Linesense digital Linear Heat Detection (LHD) cable. Alarm temperature 105˚C, maximum ambient 70˚C. Black PVC outer sheath. FM Approved.

The simple and proven technology of digital Linear Heat Detection (LHD) cable makes it a product of choice for demanding and challenging applications where other technologies struggle to work.

With its ease of installation and low maintenance, it also provides a cost-effective solution where project expenditure requires to be kept at a minimum.

The sensing cable is formed from a pair of twisted steel conductors, each with temperature-sensitive insulation and then an overall PVC outer sleeve. When the temperature-sensitive insulation reaches its 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.

The PVC outer sleeve of the H8028 offers good UV resistance allowing it to be deployed in external applications.
