Product Overview

 The CTM-230 is a detection control module that interfaces between a fire alarm control panel detection circuit or addressable node and Protectowire CTI Linear Heat Detectors. It supervises up to 4,000 ft (1,220 m) of detector cable in Class A or Class B configurations, providing one supervised detection circuit. The module monitors Protectowire Type CTI Linear Heat Detectors and does not support other normally open contact devices.
