Linear heat Detector is a proprietary cable that detects the heat at any point of its length.

The sensor cable consists of two steel conductors individually insulated with a polymer sensitive to temperature. The insulated conductors are twisted together to create a spring pressure, then is wrapped with an outer cover appropriate to the environment in which must be installed in the detector.

In the calibrated temperature, heat sensitive insulating polymer yields against the pressure generated by the radiation of heat, allowing interior conductors get in touch between them and activate an alarm signal. This action occurs at any point heated within the detector cable length. It is not required to heat a specific length to activate the alarm, or you need to calibrate the system to compensate for changes in environmental temperature where it is installed.

The linear heat Detector provides the advantages of coverage of lines with sensitivity of specific points.
