3.6 Emergency microphone
The voice alarm controller has one connector for an
emergency microphone. A hand-held emergency
microphone is supplied with the voice alarm controller.
See figure 3.2 for installation details. Turn the lock ring
clockwise to lock the plug.
3.7 BGM inputs
The voice alarm controller has 2 BGM inputs (see figure
3.3 and table 3.3). Each BGM input has a double cinch
socket. To these cinch outputs, a background music
source can be connected (e.g. a PLN-CDT Plena CD
Tuner). The signals connected to the L (left) and R
(right) cinch sockets are mixed to form a single input
signal.
