The DGM-32/64-RF Series includes data gathering modules (DGMs) that monitor dry contacts. The units communicate with the System 3505 head-end via polling radio, as indicated by the suffix –RF. The System 3505 polls the DGM panels for any change in status, which is then passed to the head end. In addition to reporting all status changes to the System 3505, the DGM panes 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-RF is suitable for an installation that will start out at, or possibly expand later to, 64 end-of-line resistor alarm inputs without relay control requirements.
The DGM-32M-RF (M=8, 16 or 24) is suitable for an installation that will start out at 8, 16 or 24 and (or possibly or expand later to) 64 end-of-line resistor alarm inputs without relay control requirements. Order this panel according to how many zones are initially desired: DGM-32-8RF, DGM 32-16-RF, etc.
The DGM-32/64-RLY-RF is suitable for an installation that will start out at (or possibly later expand to) 64 end-of-line resistor alarm inputs with relay control requirements that can be purchased separately. The –RLY suffix indicates that the DGM can be equipped with relay control initially or in the future.
