Description - Protectowire Linear Heat Detector, the main component of our linear heat detection systems, is a proprietary cable that detects heat conditions anywhere along its length. Available in a range of alarm temperatures and jacket models to suite a vast array of fire detection applications.

Construction - The sensor cable is comprised of two steel 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 an outer jacket suitable for the environment in which the Detector will be installed.
