Linear Heat Detection Cable

Brand: Fike Corporation

Linear heat detection (LHD) cable is a combination of advanced polymer and digital technologies that can detect heat anywhere along its entire length.

At the core of LHD is a twisted pair of extremely low resistance [0.05 ohm/ft (0.164 ohms/m) per twisted pair] tri-metallic conductors, sheathed in new advanced thermal polymers.

These polymers are chemically engineered to break down at specific fixed temperatures allowing the twisted conductors to make contact and initiate an alarm at the control panel without any calibration for changes in the ambient temperature.

The distance locating option allows the ability to identify and display the exact location, in feet or meters from the control panel, where the heat source interacted with the detection cable.
Features
  • As a contact closure initiating device, Fike approves up to 2,000 ft (609 m) of LHD cable per each Cheetah Xi, CyberCat intelligent input device, or SHP PRO initiating circuit
  • Approved for up to 35 ft (10.7 m) spacing
  • 0.05 ohms/ft (0.164 ohms/m) resistance per twisted pair wire, lower than any other type of linear heat detection wire
  • Lower Cost than other types of heat detection
  • Compatible with all Fike fire alarm and releasing panels
  • Multiple Alarm temperatures: 155° F, 172° F, 190° F, 220° F (68° C, 78° C, 88° C, 105° C)
  • Distance locating option available
  • Multiple alarm temperatures can be mixed on the same zone
  • Total zone length replacement unnecessary after alarm condition
  • Longer standard spool lengths available: 500 ft, 1500 ft, 3000 ft (152 m, 457 m, 914 m)
  • Nylon-coated - for outdoor and harsh environments
  • Polypropylene coated - for chemically harsh environments
  • Guidewire for spans up to 250 ft (76 m) with supports at 15 ft (4.6 m) intervals
