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.

System 2000 Commercial and Light Industrial Fire Alarm Control Panel

The FireSystem 2000 is a fully supervised, non-coded fire alarm control panel available in multiple zone configurations. The control panels are modular in design and feature individual control modules designed to meet specialized system requirements for commercial, institutional, and light industrial applications. The system is both UL listed and FM approved and conforms to applicable NFPA 72 requirements for local and auxiliary protective signaling systems.

It may also be used as part of a proprietary fire alarm system or, when properly configured, is capable of sprinkler supervisory service, water flow alarm, pre action sprinkler or deluge system release.
