• The default position of these switches is in the off position for normal
mode, which is the only mode in which the call alert tone functions
operate. In other modes, the call alert tone is automatically disabled to
avoid interference with operation.
Note: Only normal mode may be used when the EB7-4W four-wire option
module is installed.
10. Intercom Line Connection: The KB-701 contains a five-terminal,
plug-on connector for intercom line connection. This connector is
intended to be unplugged from the circuit board when connecting the
intercom line, and then plugged back on when the wiring is completed.
The connections for each pin are visible on the circuit board when the
connector is unplugged. The pinout of this connector is as follows:
Pin #1 --- (NC)
Pin #2 --- (NC)
Pin #3 --- Channel A Audio
Pin #4 --- Power
Pin #5 --- Ground (Shield)

11. Program Input: A three-terminal, plug-on connector provides the
program input to the station. Program is fed to the speaker. This level is
controlled by the program level control. If this input is connected to the
stage announce (SA) output of a main station it can be used as a paging
input. Since the level of this input is independently adjustable from the
intercom audio volume, it can be used to override the intercom audio in
all modes except remote listen-page. The program input is also
independent of the mode setting. The pinout of the program input
connector is as follows:
Pin #1 --- Ground (Shield)
Pin #2 --- + Signal
Pin #3 --- - Signal
