Thermocable ProReact Analogue Linear Heat Detection Cable (LHD)

Analogue linear heat detection systems consist of a control or interface unit, a section of four-core analog linear heat detection cable, and an end-of-line unit. These systems detect fires or overheating conditions by continuously monitoring changes in electrical resistance along the detection cable. An alarm is triggered when the resistance falls below a predetermined threshold, which is set according to the desired alarm temperature chosen by the user.

In addition, ProReact Analog Linear Heat Detection systems offer a pre-alarm option for early indication of rising temperatures. These systems can be reset following a fire or overheating event, provided the detection cable has not been exposed to temperatures exceeding 125⁰C.

Analog linear heat detection cable is available with a wide variety of outer material coatings, making it suitable for use in diverse environments. These systems are commonly used in car parks, control or data rooms, warehouses, and manufacturing plants.
