High-precision heat detection
Hochiki Europe, the manufacturer of life safety systems, has launched a range of Linear Heat Detection (LHD) equipment to provide specialist high-precision heat detection over large distances, in challenging environments.
The LHD System is designed to provide early detection of fire and overheating in circumstances where other forms of detection would not be viable.
Hochiki Europe’s LHD range offers both analogue and conventional products. The conventional Linear Heat Detection Cable (LHDC) is able to identify the zones in a fire condition, while the addressable LHDC can isolate the heat to within one metre. This fast response ensures facility owners and managers have time to deal with outbreaks before there is any damage to infra-structure or equipment.
Providing the LHDC has not been subjected to excessive temperatures, the alarm condition can also be reset at the zonal controller which is particularly useful when carrying out annual maintenance.
Capable of utilising cabling up to 2 kilometres, the LHDC system is ideal for use in a range of applications. These include road and rail tunnels, conveyor systems, as well as indoor car parks and cable trays in building interiors. It can even be used in the harsh environments found in recycling and food processing plants, as its heat detection abilities are not affected by the build-up of dust and vapour, unlike standard equipment.
In addition, the range includes infra-red transit heat detectors which are designed to monitor the temperature of the contents of a conveyor belt and can be used in manufacturing facilities.
