4-Wire Call Receive

The DSI 2008 receives call signals from the 2-wire system, then converts this to relay contact closure for use as a 4-wire call

receive indication. The DSI 2008 also provides +5 VDC which can be connected to the relay contacts to generate a DC output

signal instead of a contact closure. Connections for a simple contact are shown in Figure 6 on page 16.
