Linear heat sensing cable is designed to detect the fire conditions in critical applications across industries. LHS Cable consist two twisted cores of very low conductor resistance tri-metalic conductors, insulated & sheathed with advance thermal polymers. These advance thermal polymers have characteristics to breakdown at fixed temperature, results in allowing twisted conductors to make a contact and initiate an alarm in fire system. Selection of LHS cable for fastest alarm response is determined from maximum ambient temperature of the hazardous area or equipment to be protected
