Linear Heat Detector Cable

In temperature sensitive environments early detection of an abnormal change is crucial to protect safety of life critical processes and reduce losses.

Linear heat detector cable.

Linear heat cable versatile economical heat detection. The alarmline linear heat detector provides specialty heat detection for non traditional applications such as open areas tunnels belt conveyors cable trays and floating roof oil tanks just to name a few. Linear heat detectors by protectowire can best be described as a continuous run of spot heat detectors within a versatile cable. Lios de tect is a robust linear heat detection system based on optical fibers.

The insulated conductors are twisted together to impose a spring pressure. Thermocable has developed a range of exceptionally durable linear heat detection lhd technologies which provide extensive and continuous coverage are easy to install and fully integrate with. The linear heat detection cable lhdc system from hochiki is designed to provide early detection of fire and overheating in circumstances where other forms of detection would not be viable either due to inability to sustain the environmental requirements or through prohibitive costs. Linear heat detection lhd also known as linear detection wire or linear heat detection cable or linear heat is a very commonly used method of fire detection it can detect a fire anywhere along the length of the cable and can be of lengths in excess of a kilometer.

Unlike conventional detectors the protectowire linear heat detector s unique form and construction make it the detector of choice for all types of installations. With a range of up to 10 km and a sampling interval down to 25 cm the system is ideal for fire detection in tunnels and metros as well as large facilities like warehouses and industrial facilities. Applications can range from building fire alarm systems to mobile plant machinery. Designed for use in a wide variety of indoor and outdoor applications lhd fire alarm cables are particularly suited for areas where installation or maintenance access is in a physically demanding or hazardous.

The sensor cable is comprised of two steel conductors individually insulated with a heat sensitive polymer. Protectowire linear heat detector is a proprietary cable that detects heat conditions anywhere along its length. The two cores are separated by a polymer plastic that is designed to melt at a specific temperature commonly 68 c for building applications and without which causes the two cores to short.
