CTM-230 Interface Module (CTI™)

The CTM-230 is an interface module with LEDs for CTI linear heat detectors. The module provides one (1) supervised detection circuit that may be field wired for either Class A (Style D) or Class B (Style B) service.

The initiating device circuit is capable of monitoring a maximum of 4000 feet (1220 meters)combined total of Protectowire Type CTI™ Linear Heat Detector and Type T thermocouple extension grade cable, this module is not compatible with other types of NO initiating devices.

CTM-230 CTI Interface Module Options

  • CTM-230: Module w/LED indicators less enclosure
  • CTM-230E: Module w/LEDs in NEMA-4X (IP66) Enclosure

EPC (Extruded Polyvinyl Chloride) – is a durable flame-retardant vinyl outer jacket designed for interior commercial and industrial applications. Features of this jacket include low moisture absorption, resistance to many common chemicals, and excellent flexibility at low temperatures.

XCR (Extreme Corrosion Resistance) – is a high-performance fluoropolymer jacket designed for both interior and exterior environments. Features of this jacket include excellent chemical resistance, abrasion resistance, weather resistance, and high-temperature performance. XCR is the only heat detector that is FM-approved for corrosive environments.

LSZH (Low Smoke Zero Halogen) – is a durable outer jacket designed for interior commercial and industrial applications requiring low smoke zero halogen performance. Features of this jacket include low moisture absorption, resistance to many common chemicals, and excellent flexibility at low temperatures.

XLT (Extreme Low Temperature) – is an outer jacket specifically selected for cold storage and freezers. Features of this jacket include low moisture absorption and excellent performance in extremely low temperatures. This detector has been UL and FM tested to –60°F (–51°C)

EPR (Extruded Polypropylene Rubber) – is an outer jacket designed for both interior and exterior environments. Features of this jacket include good abrasion resistance, chemical resistance, and weather resistance over a wide temperature range.
