Protectowire CTI-135XLT (3,280 feet)

The Protectowire family of Confirmed Temperature Initiation Linear Heat Detectors are advanced multi-sensor detectors consisting of models with alarm temperatures ranging from 135°F (57°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.
