Figure 28 shows how to wire an Annuncicom 200 to the BOWS Interface
board at a slave.
Figure 28. Wiring an Annuncicom 200 to the Slave BOWS Remote Audio
Input.
The Annuncicom 200 in the master is configured to broadcast audio to
the modules in the slave BOWS when its Input 0 input is activated (by the
BOWS emergency PA Mic‟s PTT switch). The master Annuncicom 200 is
also configured to activate the output relay on Annuncicom 200 or the
RTS output on the Exstreamer 100 module at the slave BOWS. This
output is used to control the ACTIVE signal on the Remote Audio port.
If the PA announcements are not required to override the
Alert/Evacuation tones at the slave BOWS, the audio output of the
module can be connected to the background music input on the Slave
BOWS as shown in Figure 29.
