Linear heat and fire detection cable (LHD) will sense an excessive temperature or fire condition at any point along its length and display its location at the control panel. Designed for use in a wide variety of fire and heat detection applications, LHD cable is particularly suited for harsh environmental conditions, applications where maintenance access is in a physical or hazardous area, and/or where there is a requirement to cost-effectively install detection in close proximity to the hazard.
