The LHS Linear Heat Sensor cable is a flexible, durable and cost-effective fixed-temperature fire detector, suitable for protecting a wide range of commercial and industrial fire applications. LHS is a small diameter cable capable of detecting heat from a fire over its entire length. The sensor cable consists of a twisted pair of copper coated steel conductors covered by a temperature sensitive insulation. The LHS Linear Heat Sensor is Underwriters Laboratories Listed and Factory Mutual Approved and is designed for open area as well as proximity detection. See Table 1 on page 2 for specific listings. A wide range of operating temperatures are available for proper system design, including confined areas or harsh environments which prohibit the use of other forms of detection. LHS is compatible with any fire control panel that is capable of accepting contact closure type initiating devices.
