H9650 Linesense digital Linear Heat Detection (LHD) cable. Alarm temperature 240˚C, maximum ambient 200˚C. White Fluoropolymer outer sheath. FM Approved.

The simple and proven technology of digital Linear Heat Detection (LHD) cable makes it a product of choice for difficult 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 with temperature-sensitive insulation and then an overall Fluoropolymer 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 Fluoropolymer outer sleeve of the H9650 offers excellent chemical and water resistance, allowing it to be deployed in harsh and dirty environments.
