Linear Heat Sensor Cable

Product Literature

LHS Linear Heat Sensor cable is a flexible,durable and cost-effective fixed-temperature detector that is suitable for protecting a wide range of commercial and industrial environments. LHS Cable comes in a variety of cable jackets and operating temperatures allowing you to select the perfect cable-type for a particular job. The LHS Cable detects heat from a fire over its entire length and it can be connected directly into the fire panel initiating circuit, eliminating the need for extra, costly equipment. The LHS Cable is FM Approved and being a contact shorting device, is compatible with all fire control panels.

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 19 AWG copper coated steel conductors covered by a temperature sensitive insulation, and protected by either a plastic braid or jacket for various environmental applications. The LHS Linear Heat Sensor is Factory Mutual Approved and is designed for open area as well as proximity detection. A wide range of jackets and 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.
