Linear heat detection uses a heat sensing cable that detects a rise in temperature anywhere along its length. It continues to work where dust, moisture, vibration or extreme temperatures would defeat other detectors, and it can follow the shape of the asset it protects.
Typical uses are tunnels, conveyor belts, cable trays and cable tunnels, car parks, cold stores and industrial plant. Resettable linear heat detectors are covered by EN 54-22 in Europe. AlarmLine II from Kidde Global Solutions is designed for these demanding applications.
