Discrete Control Module (DCM) Mounting

The DCM provides 16 control points and 2 discrete alarms.

Discrete Control Module DCM (Dial-up) 16 controls, 2 opto isolated alarm inputs. Relays operate momentary or latch/release. Relay and alarm status displayed on LEDs. Includes 1200 baud internal modem (TRIP protocol), craft port, T/DCM software and cable. DCM may work in conjunction with a DPM to "Echo" alarms via a dial link.

Discrete Control Module DCM (Dedicated) As above, for dedicated DCPF facility. Communications interface determined by "docking module" on line port. Specify desired interface with dash number, per note below.

DB37 Wire Wrap Block - One or Two 1 ft connectors, Pre-wired DCM: A block that is used to make Wire Wrap connections to a DPM or DCM RTU. Features two alarmed fused inputs, panel/wall mountable, and clear plastic cover. This model is perfect for connecting to single DPM or DCM on a 19"/23" rack mount panel.

DCM Interrogator Software Module (1-Port or Multi-Port): Allows the IAM alarm management systems to communicate with devices that use the DCM protocol (MAT's and CPM's).


DCM Application

The DCM normally communicates with an alarm master, such a The T/Mon NOC or IAM alarm management system, via a telecom network that may include several other DCM's and other remote devices. It can also report to a PC running T/DCM software.

DPM/DCM Echo Mode

In an echo application the DCM communicates directly with a DPM, which is its complement with 16 alarm inputs and 2 control relays. The DCM control relays operate when the DPM detects an alarm, providing 16 hard, contact-closures that follow the alarm inputs point-for-point.
