Linear heat detection senses excessive temperature or fire conditions at any point along the cable and alerts the control panel. These cables may measure several miles long and are often the ideal solution to provide early warning detection in challenging environments such as long tunnels, spacious warehouses and more.

Fike Distributed Temperature Sensing (DTS) – Measures temperatures in real time along the length of the fiber optic cable by transmitting pulses of laser light and analyzing the return signal, and allows precise identification of the fire.

Protectowire Linear Heat Cable – Detects early stages of fire when increased heat melts a heat-reactive polymer. When the two conductors touch, an electrical short occurs and the connected PIM-530 module relays the information to the fire panel.
