Example 3 - Optional Plug-In Module Application
The AA120M incorporates a module port that supports a variety of system options. For this example, a
plug-in chime module is used to announce a request for building entry. The chime sound would only go
to one speaker located over a security guard's area. In addition to the chime module, there is paging,
background music, and message on hold connected.
• Connect the customer's PBX page port to INPUT 1. Note: The INPUT 1 Trim and Sens will need
to be adjusted after all the settings and connections have been set.
• Set Dipswitch 10 to the "LINE" position.
• Set INPUT 1 to Mute Send.
• Connect the telephone message repeater to INPUT 2.
• Set INPUT 2 to Mute OFF. Turn down INPUT 2 volume control so no audio will be present at the
speaker terminal.
• Connect Zone 3 to the Telephone PBX MOH port. Adjust INPUT 2 Zone 3 Level as needed.
• Connect a BGM player to INPUT 5. Note: The input gain of this channel may need to be changed for
proper level balance. Dipswitch 6 allows you to select between a 100mV or 300mV input sensitivity.
• Install Chime Module to Input 6. Connect contact closure. Make sure front panel input level control is
turned down.
• Adjust INPUT 6 Zone 2 Level as needed.
• Connect the Chime Speaker to Zone 2 output terminals.
