SYSTEM OVERVIEW
The Interview Window Intercom System is designed for high-quality one-to-one hands-
free voice communications and multi-zone paging. It is built to enhance intelligibility
of the human voice through background and outside noises. Installation involves
running one 2-pair cable as a paging bus, and 3-pair cable between a master and its sub-
station.
Speakers, such as outdoor-rated horn speakers or ceiling speakers, may be grouped in
such a way as to create Paging Zones. One Interface Box is used per Zone. Typically, a
Paging Zone consists of 2 or 3 speakers in one room or two nearby rooms. By a simple
dip-switch setting, each master can designate which 2 of up to 6 zones it can page. In
addition, each master can page all zones at once.
Background music or other program material may also be added to the system in such a
way that when one zone is paged, the program source is interrupted in that zone only.
Each zone may have its own program source or zones may share the program material.
This is accomplished by a simple 1-pair connection.
The interviewer can speak to the sub-station in one of three ways: 1) through the built-
in microphone in the Master; 2) by speaking into an optional thin gooseneck
microphone; 3) using an optional wireless headset/microphone that allows the
interviewer a free range of movement without interfering with their communication.
