Linear Heat Protection & Detection Systems
Linear Heat Detection (LHD) is a versatile and economical fire detection product designed for use in a wide variety of fire and heat detection applications This cable is particularly suited for harsh environmental conditions. This could mean the maintenance access is in a physical or hazardous area, and/or where there is a requirement to cost-effectively install fire detection in close proximity to the hazard. Linear Heat Detection cable is a combination of advanced polymer and digital technologies that can detect heat conditions anywhere along the length of the cable. The cable is comprised of two tri-metallic conductors individually insulated with a heat sensitive polymer outer-layer, and engineered to break down at specific fixed temperatures. This allows the twisted conductors to make contact and initiate a fire alarm condition at the control panel without any calibration for changes in the ambient temperature. Nor is it required that a specific length be heated in order to initiate a fire alarm, adding to the versatility of this unique product.
For further flexibility the Linear Heat Detection cable can be utilized with fire alarm control panels by using either addressable monitor modules or by connecting the cable directly to the detection circuit of a conventional fire panel. In addition, the distance locating option allows the control panel to identify and display the exact location, in feet or meters from the fire panel where the heat source interacted with the linear heat detection. That's a tremendous amount of valuable information in a small, easy to install and maintain fire detection package. T&R has installed this system in tunnels, under raised floors, and in cable trays. Some of the other applications where this can be used with a switchgear, a freezer/cooler container, archive and warehouse storage, elevator shafts, cooling towers, conveyors, cable spreading rooms, terminal rooms, generators, bridges, engine bays, and many others. To see if this system is right for you please call T&R Alarms and we will provide you with a free consultation.
