What Is Digital Type Linear Heat Detection System?

Digital Type Linear Heat Detection System (LHDS) is a device in which detection is continuous along a path. It is designed to provide an early detection of fire and overheating in situations where other forms of detection would not be practical. The linear heat detector cable is capable of sensing heat anywhere along its length, initiating an alarm once its fixed activation temperature has been reached. When the ambient temperature meets or exceeds the detector peaks temperature the heat-sensitive insulation that is softens allows the wires to make electrical contact, initiating an electrical short triggering an alarm.

Composition Of Linear Heat Detector Cable

• Steel Conductors – composed of (a) steel, to provide tensile strength, (b) copper, to increase conductivity, and (c) tin, to resists corrosion
• Protective Tape – advanced insulation provides temperature specific activation, it softens on certain temperature
• Outer Jacket – comes with 4 jacket types for various

Applications and environments

a.EPC & CTI (Polyvinyl Chloride) – ideal for general, multi-purpose applications

b.Type XCR & CTI (Fluoropolymer) – ideal for extreme environments and includes excellent resistance to chemicals and UV.

c.Type XLT (Proprietary Polymer) – ideal for low temperature such as cold storage

d.Type PLR (Polypropylene Elastomer) – ideal for outdoor applications

Advantages Of Linear Heat Detector Cable

• Detects heat at any point along its length
• Minimal false alarms
• Easy installation and low maintenance
• Can be installed near to hazards
• Can be use in extreme conditions and can resist corrosion, hemicals, moisture and extreme temperatures
• Long life span

The detector can be used with any domestic and foreign manufacturers of fire alarmcontroller connection glance at automatic fire detection system, which can effectively protect the following objects:

• Cable facilities: cable tunnel, shaft, mezzanine,cable tray, etc:
• Electric utilities: distribution equipment, switchgear, transformers and reactors;
• Oil, gas, hydraulic, lubricating oil storage, oil tank, gas tank, oil boilers, gas boilers, fuel injection(baked) booth:
• Belt transmission facilities, coal delivery, transport belts and automated production lines.
