Linear Heat Sensing Cable System Sensor

Linear heat detectors by protectowire can best be described as a continuous run of spot heat detectors within a versatile cable.

Linear heat sensing cable system sensor.

The lhs linear heat sensor is designed for open area as well as proximity detection. Alarm panels via system sensor monitor modules. A switching cable where a change in state of internal insulation caused by temperature rise to a pre defined level allows a short circuit or hot junction to occur between two twisted tin plated copper. Designed for use in a wide variety of indoor and outdoor applications lhd fire alarm cables are particularly suited for areas where installation or maintenance access is in a physically demanding or hazardous.

Analogue cable is installed in conjunction with an end of line eol device for continuity monitoring and a modulator providing selectable alarm thresholds programmed before shipping fire and fault outputs. Linear heat cable versatile economical heat detection. The sensor cable is comprised of two steel conductors individually insulated with a heat sensitive polymer. Linear heat detection lhd also known as linear detection wire or linear heat detection cable or linear heat is a very commonly used method of fire detection it can detect a fire anywhere along the length of the cable and can be of lengths in excess of a kilometer.

Applications can range from building fire alarm systems to mobile plant machinery. The 900 series is an analogue heat sensing cable containing insulators of which resistance varies proportionally to changes in temperature. Description the linear heat detection cable lhdc is a continuous heat detector in the form of a cable. System sensor linear heat sensing cable has two different variants digital lhs cable and analogue lhs cable.

The sensor is completely passive over its entire detection range and the de tect fiber optic linear heat detection can therefore be carried out in areas where high safety risks exist even in areas with a risk of explosion. Description protectowire linear heat detector the main component of our linear heat detection systems is a proprietary cable that detects heat conditions anywhere along its length. Protectowire linear heat detector is a proprietary cable that detects heat conditions anywhere along its 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.

Of twisted pair tri metallic conductors sheathed in new advanced thermal polymers. System sensor 800 series digital linear heat detector and 900 series analogue linear heat detector offer early detection of fire and overheating conditions in industrial high risk hazards as well as many types of commercial applications.
