4-Wire Call Signal Connections
FIGURE 5. Call signal connections for ADAM, ADAM CS, and Zeus Intercom Systems. This example uses GPI outputs #1 and #2 and GPI Input
#1; however, you may use any other available GPI inputs and outputs. The Call Enable/Inhibit connection is optional. It gives you the ability to
disable call signalling using a GPI output. However, when connecting to a Clear-Com intercom system, if an enable/inhibit switch is not connected, a
jumper must be installed for any other application. You DO NOT have to use GPI outputs for call signalling or enable/inhibit, you can use simple
switches instead, as shown in Figure 6 on page 11.
