The DGM-16LS is a Data Gathering Module unit that is suitable for an installation requiring up to sixteen (16) End of Line resistor inputs.
DGM units communicate with the System 3505 Prism LX™ devices via supervised, bi-directional, polling multiplex communication using any combination of RS-485, Fiber, Audio Modem, Ethernet or Polling Radio (RF). The Line Driver Rack and the appropriate Line Driver Cards allow the DGM units to work in an existing communication system, without costly upgrades, or replacing current field equipment and wiring. This capability saves our customers thousands of dollars and system down time.
DGM units are continually polled by System 3505 Prism LX™ for any change of status.
All status changes are held in memory by the DGM, even if the condition clears. Supervised inputs report any break in the circuit as a Trouble condition by zone.
Up to five hundred (500) DGM units can be installed in any system.
