Digital linear heat sensing cablesfixed temperature linear heat detection cable features a twisted pair of extremely low resistance . 05 ohm/ft. Of twisted sheathed in, Pair tri, Metallic conductors new advanced thermal polymers. These polymers are chemicallyengineered to breakdown at specific fixed temperatures allowing the twistedconductors to make contact and initiate an alarm at the management console without anycalibration for changes in ambient temperatures. The consideration that affects which detection temperature wire to use is the maximum ambient temperature of the hazard area or equipment to be protected. The proper temperature model must be selected to supply the fastest alarm response to a potential fire condition without creating false alarm conditions. In the selection process its critical to consider the hazard areas highest potential ambient temperature.
