Description: Linear Heat Detector, the main component of our linear heat detection systems, is a proprietary cable that detects heat conditions anywhere along its length. Available in a range of alarm temperatures and jacket models to suite a vast array of fire detection applications Principles: The primary mechanism of heat (fire) detection is that inner core insulating polymer is specially formulated such that it plasticizes at a specific temperature. The cable is constructed such that the twisted steel cores are in tension, and at the polymer trigger temperature the conductors connect. This provides an alarm signal to any associated monitoring device. The LHDC may be used as a simple switch to operate a relay etc. However in most fire alarm installations the minimum requirement is that the LHDC circuit is monitored for disconnections by means of an End Line (EOL) device and an appropriate Fire Alarm Channel or Address Loop interface unit. LHS CABLE can provide more sophisticated monitoring schemes that can discriminate and identify Zone / Area alarm initiations whilst maintaining a single length of LHDC. The LHS Digital Linear Heat Detectors are designed to provide early detection of fire conditions and overheating in circumstances where other forms of detection would not be viable, either due to inability to sustain the environmental requirements or through prohibitive costs. Extensive single zonal lengths of the Linear Heat Detector (LHD) may be installed with the ability to trigger alarms for hot spots occurring on very small sections of the overall cable. The LHDC may be employed in a wide variety of applications but is particularly suited where there is a harsh environmental condition, a physical or hazardous maintenance access constraint to the protected area, and/or requirements to cost effectively install detection in close proximity to the risk(s) The Key features are:- Early detection of hazards at temperatures well below flame point Rugged construction for use in harsh environments. Ease of installation - wide range of fixings available. Compatible with many existing zone monitors / control equipments. Fixed Alarm Trigger Temperature Intrinsically Safe configurable for Hazardous Areas. Compliant with industry standards Extensive range of proven applications. UL Approved, ULC LISTED
Construction: The sensor cable is comprised of two steel conductors individually insulated with a heat sensitive polymer. The insulated conductors are twisted together to impose a spring pressure between them, then wrapped with a protective tape and finished with an outer jacket suitable for the environment in which the Detector will be installed. Application: LHDC is versatile in that it can both provide an alternative to point heat detectors in conventional (space) protection situations and it may also be readily installed in very close proximity to monitored hazards. The detector is particularly suited to applications where harsh environmental conditions preclude the use of other forms of detection. The low maintenance requirement of the detector provides a unique solution to fire detection in areas that have access restrictions due to either physical difficulties or personnel health risk. The cable may be installed in Hazardous Areas by means of Intrinsically Safe Zener Barriers. When the protected area is remote from the monitoring equipment interposing cables may be employed. Linear Heat Detector is made in multiple temperature ratings to allow for differences in normal or ambient temperature. Guidelines for selecting the proper detector temperature rating are the same as for automatic sprinklers and other heat actuated devices. Refer to the Temperature Rating Chart for proper model selection based upon installation temperature limits. The Detector s product range consists of four distinct types of cable. Each designation identifies a specific outer jacket material which has unique characteristics that have been selected to accommodate the widest range of installation environments.

The Alarm Point Location Meter An exclusive feature of Fire System control panels, the alarm point location meter is designed to locate a heat actuated point on a length of Linear Heat Detector. The Meter provides a means to display the alarm point location, represented as a linear distance in Feet or Meters, from the start of the 0portion of the circuit to the heat actuated alarm point on the detector. Alarm Point Location Setup: Each zone is field calibrated after installation to eliminate copper feed cable resistance from the Alarm Point Location reading. This is done by manually shorting the detector at the beginning of the zone and adjusting the display to zero "0000". Zone Mapping: When a Linear Heat Detection System using the Alarm Point Location Meter is first brought online, points along the detector correlating to a floor plan or installation detail can be temporarily shorted an measured. Each distance reading can then be marked on the floor plan or detail at it's corresponding point. In the future, a reading of the Alarm Point Location Meter can be referenced on the floor plan or detail, making location of the overheated (alarm) portion of the wire easier to locate.
Accessories: Our company offers an assortment of fasteners and splicing devices to facilitate installation for both standard and special applications. Full details are available upon request.
