Construction - Protectowire Linear Heat Detector is a proprietary cable that detects heat conditions 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.

Operation - 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 between conductors, permitting them to move into contact with each other, thereby initiating an alarm signal. It is not required 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.

AlarmLine Linear Heat Detection

Rapid response to both localized fires and wide area overheating. Suitable for virtually all environments; dusty, hazardous, vibrating, even inaccessible. Easy-to-install, yet rugged, with coatings of fire-retardant polymer, extruded nylon or braided metal. Short circuit discrimination. Self restoring up to 390° F. AlarmLine is engineered to eliminate false alarms and lower maintenance costs.

Pyrotronics - Seimens 

FPT-11 intelligent Thermal Detector provides and advanced method of detection, address programming and supervision combined with sophisticated control panel communications. Operates with the Siemens Fire Safety MXL family of control panels including MXL, MXL-IQ and MXLV.

Catalog sheet #6176

Continuous Fire Detection (CFD)

Unique fire and overheat detection, recommended for you most harsh and demanding applications. Discrete (point) sensing permits alarm at any point along length, regardless of rate-of-rise or average ambient temperature. Alarm set points from 255°F – 1250°F. Auto reset after multiple exposures above 2000°F.
