Protectowire thermal imaging cameras, powered by Planck Vision Systems, are superior to traditional systems that typically alert to fire only after the visible consequences of smoke and flame are present. Thermal cameras can help to prevent the destruction of goods and loss of life by monitoring for abnormal heat conditions before fires erupt.

The Standard Digital Protectowire Heat Sensitive Cable (PHSC) linear heat detector can best be described as a continuous run of spot heat detectors. It is capable of sensing heat anywhere along its length and initiates an alarm once its fixed activation temperature is reached.

The CTI linear heat detector is a twisted pair of dissimilar spring conductors which are insulated with a heat-sensitive material. This material is designed to soften and allow the conductors to short when exposed to a specific alarm temperature. The dissimilar conductors, when shorted, form a temperature measurement junction called a thermocouple.

This product is best described as a continuous linear thermometer actively reporting temperature readings in real time. The restorable linear heat detector is comprised of quartz fibers enclosed in a low smoke zero halogen jacket. Immune to all EMI and RFI, the fiber optic linear detector can be configured to offer custom alarm criteria and zone sizes up to 30,000 feet (10 + km) in length.
