DATA GATHERING MODULE
DGM units communicate with the System 3505 Prism LX™ devices via supervised, bi-directional polling multiplex communication using any combination of RS-485, Single or Multi-Mode 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.
DGM panels also contain a relay that is controllable from the System 3505 Prism LX™ via the Relay Control Option (sold separately) additional relays can be added in blocks of eight (8) relays to a total of sixty four (64) relays per DGM. The Relay Control Option provides user-defined, manual and programmable (If “X” do ”Y”) control of the relays. Relays can be used to control electronic locks, preprogrammed annunciation devices, sirens etc.
Up to five hundred (500) DGM units can be installed in any system.
Order this panel according to how many zones are desired initially: DGM-32-8M, DGM 32-16M, etc.
