Linear Heat Detection (LHD) is an advanced fire detection system that employs a heat-sensitive sensor cable to identify temperature increases along its entire length. Unlike conventional point detectors, which only monitor specific areas, LHD provides continuous coverage and can detect heat or fire at any point along the cable. This makes it particularly effective in challenging or expansive environments—such as industrial facilities, tunnels, cable trays, and storage areas—where traditional detection methods may be impractical. Additionally, LHD systems are capable of monitoring extended distances, ensuring early and reliable fire detection across large or complex spaces.
