CTM-530 Module (CTI)
CTM-530 Module and the CTI Linear Heat Detector were invented to reduce incidences of false alarms due to mechanical damage to the detector. Using thermocouple technology, a CTI Linear Heat Detector confirms whether or not a true alarm condition exists. The CTI Linear Heat Detector control module continuously monitors the detectors’ continuity. In the case of an open circuit, the module reports an open fault condition.
Features and specifications include:
- Temperature verification and short circuit discrimination
- Engineered and designed for use with suppression systems
- MUST be connected to a CTI Linear Heat Detector
- Integrated Protectowire Alarm Point Location Meter with field calibration
- CTM-530 control module can support up to 4,000 feet (1,220 meters) of CTI Linear Heat Detector per zone
- Modbus over RS-485 communications
- 4-20 mA outputs for status and alarm point location
- 64 event history log (FIFO)
- 4×20 LED backlit LCD display
- Approved for use in hazardous locations
CTI Series (CTI & CTM-530)
Using thermocouple technology, the CTI Linear Heat Detector can distinguish between a short caused by physical damage or a short caused by heat actuation. Dissimilar metal conductors enable the CTI Linear Heat Detector to determine the exact alarm point location as well as the temperature of any short. If the temperature of the short is below the linear heat detector’s fixed temperature, a short fault or trouble condition is initiated. If the temperature of the short is above the linear heat detector’s fixed temperature, an alarm condition is initiated.
