Linear Heat Detection (LHD) provides fast and reliable detection of fire or overheating. It is suitable for use in most environments and is unaffected by airflow, hazardous chemicals or contaminants and for other areas where traditional detection types may underperform.
A Linear Heat Detection system typically consists of at least one length of heat sensing cable and one controller. The heat sensing cable is installed along or around the area to be protected. Heat sensing cable is available with a variety of outer coatings making it suitable for a range of different applications.
When a fire or overheat event occurs, the temperature of the cable increases. Once the cable reaches a predefined temperature, the controller reports an event to the fire alarm control panel. The controllers can also provide the location of the event to allow fires or potential fires to be quickly identified and dealt with.
Linear Heat Detection is well suited to a variety of applications, including: Cable trays, Conveyor Belts, Vehicle Tunnels, Car Parks, Warehouse Racking, Waste Recycling Centres, Hazardous Areas, Power Stations, Ships and Marine
