Digital Linear Heat Sensing Cables

Linear Heat Detection Cable consist of a twisted pair of extremely low resistance tri metallic conductors, coated in advanced temperature-sensitive thermal polymers which is chemically engineered to breakdown at particular fixed temperatures allowing the twisted conductors to make contact and initiate an alarm at the control panel. This linear cable can detect a fire anywhere along its entire length.
The proper temperature model must be chosen to provide the fastest alarm response to a potential fire conditions without creating false alarm conditions as it’s a co-axial cable which exerts a defined change in electrical resistance of internal polymer when subjected to changes in surface temperatures. Fault indication of open and short circuit condition on the sensor cable can be provided by system monitoring through an associated electronic interface unit.
