LHD – CTI Linear Heat Detector Interface

The CTM-530 provides a single zone interface for Protectowire Type CTI™ Linear Heat Detectors, using Protectowire’s patented CTI technology. When paired with Protectowire Type CTI Linear Heat Detectors, the module can distinguish between a mechanical short in the linear heat detector and a thermal alarm activation, thereby greatly reducing the risk of false alarms. This multi-criteria detection method provides for short circuit discrimination, a feature previously unavailable for digital-type linear heat detectors.

The CTM-530 is also available with an IP66 Enclosure.
