The Protectowire family of Confirmed Temperature Initiation Linear Heat Detectors, are advanced multi-criteria detectors consisting of models with alarm temperatures ranging from 155°F (68°C) to 356°F (180°C). Each Detector is comprised of two special metallic alloy 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 a durable flame retardant outer jacket.
