DGM-64, 64 Zone With LCD Display

Product Information

The DGM-32/64 Is a data gathering module (DGM) that monitors dry contacts. The DGM units communicate with the System 3505 Prism LX™ head-end via Isolated RS-422/485, audio modem, RS-232, Fiber Optics cable, or Ethernet. The System 3505 Prism LX™ polls the DGM panel for any status change at the DGM. 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 begin with (or expand later to) 64 endof-line resistor alarm inputs with or without relay control systems.

All models are housed in steel enclosures with step-down transformer, tamper switch, CAM lock, data-link interface, LCD display, keypad, 60-hour standby battery, and built-in battery charger. Each zone can be bypassed by using the internal keypad. Any zone that is out of service reports its status to the head end equipment.

All panels are powered by 117 VAC through the internal step-down transformer (12VDC backup). Loss of AC power for more than 15 seconds will be reported to the System 3505 Prism LX™ for display. The reporting delay can be changed by the user to any value between 1-90 seconds. Should the battery voltage drop below 10.5 volts, a “Low Battery” condition will be reported for display. In normal operation, the DGM internal charger maintains the standby battery at full charge. Should a loss of power occur, all panels are capable of switching from AC to battery power without interruption in service.

Each zone input has internal lightning and surge protection and Ground Fault Detection.
