Protectowire Linear Heat Detector is a proprietary cable that detects
heat anywhere along its length. 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.
Protectowire is a fixed temperature digital sensor and is therefore capable of initiating an alarm once its rated activation temperature is
reached. At the rated temperature, the heat sensitive polymer insulation
yields to the pressure upon it, permitting the inner conductors to move
into contact with each other thereby initiating an alarm signal. This
action takes place at the first heated point anywhere along the
Detector’s length. It does not require that a specific length be heated in
order to initiate an alarm nor is system calibration necessary to compensate for changes in the installed ambient temperature. Protectowire
Linear Heat Detector provides the advantages of line coverage with
point sensitivity.
