CTM-230 Interface Module (CTI)

The CTM-230 is a detection control module that acts as an interface between a fire alarm control panel detection circuit or addressable node and Protectowire CTI Linear Heat Detectors. The CTM-230 module can supervise up to 4,000 feet (1220m) in a Class A or Class B configuration.

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. Protectowire offers thermocouple extension grade cable in 200 and 500 ft coils (part # PWTX-200 and PWTX-500 respectively. The CTM-230 initiating circuit is designed to monitor Protectowire Type CTI Linear Heat Detectors only and does not support other types of normally open contact alarm initiating devices.

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.
