What are Linear Heat Sensing Cables and how do they work?
Linear Heat Sensing Cables (LHS cables) are heat sensors that offer heat detection through out its length. They can be used at cable trays, storage racks, conveyors etc. for early fire detection, where an installation of a detector device is impractical.
LHS cables are of type Analog and Digital. Each consists of two cores of copper wire with a polymer separating them. They detect heat as the resistivity separating polymer varies in proportion to the temperature in its surveillance.
LHS Interface Units are those that interface communication and settings of the LHS cable with the Control panel.
