AD LHSC 700-070
Digital Linear Heat Sensing Cable (LHSC)
These cables are heat sensors that offer heat detection all through its length. It can be used to provide early fire warning at areas such as cable trays, storage racks, conveyors etc. where an installation of a detector device can be impractical.
Digital LHS cables that comprises of a twisted pair of 2-core copper wire allows a short circuit or a ‘hot spot’ between two twisted joints at the time of fire. With the ‘hot spot’ as reference, digital LHS cable can determine the exact location in fire. However, they cannot be reused like the Analog type LHS cables.
These cables are connected with the relevant LHSC Interface Unit (LIU) to establish communication with the Control panel.
- Exact location detection
- Early detection of fire hazards at temperature well below flame point
- Mechanical and chemical protection available
- Fixed alarm trigger temperature
- Easy to install
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.
