DGM 32/64

The DGM-32/64 Is a data gathering module (DGM) that monitors dry contacts.  The units communicate with the System 3505 head-end via dedicated cable pair.  One pair of wires is capable of monitoring multiple panels.  In turn, each DGM panel monitors 32 or 64 end-of-line resistor alarm inputs.  The System 3505 polls the DGM panel for any change in status; any status change is passed to the head end.  Additionally, the DGM panels hold the changes in memory—even after a condition clears. Supervised inputs report any break in the circuit as a Trouble condition by zone.

The DGM-32/64 is suitable for an installation that will start out at (or expand later to) 64 end-of-line resistor alarm inputs with or without relay control systems.
