Protectowire CTM-530 Series control modules process alarm and trouble signals from PHSC-Series linear heat detection cable circuits and interface them to the connected fire alarm control panel. The CTM-230 is a replacement component for maintaining installed CTM-530 Series units in service. CTM-Series controllers are used in tunnels, conveyor galleries, transformer rooms, and cable tray installations where PHSC linear heat detection cable provides continuous thermal monitoring along the full cable length. Replacement must use the exact CTM variant specified for the installed system to maintain UL listing and FM approval for the complete detection circuit.

Verify panel/device family compatibility before ordering.
