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.
