25 Background music
25.1 Introduction
The background music (BGM) is controlled using the
BGM controls on the front of the voice alarm controller,
voice alarm router and their remote control and remote
control extensions. Proceed as follows to route BGM:
1 Select the BGM source (see section 25.2).
2 Select the zones (see section 25.3).
25.2 Select BGM source
Select the BGM source with the Select button on the
front of the voice alarm controller (see figure 25.1). A
green LED indicates the source that is selected.
• If the source is a CD player or a tuner that is
connected to the CD/Tuner input, choose CD/Tuner.
• If the source is an auxiliary source that is connected
to the Aux input, choose Aux.
25.3 Select zones
The BGM is distributed to the zones with the Zone
select buttons on the voice alarm controller (see figure
25.2), voice alarm router, remote controls and remote
control extensions. A green LED indicates the zones to
which BGM is distributed.
•If the Zone select indicator is off, no BGM is
distributed to the zone. Push the Zone select button
to distribute the BGM to the zone.
•If the Zone select indicator is on, BGM is distributed
to the zone. Push the Zone select button to stop
distributing the BGM to the zone.
25.3.1 Adjust volume
The voice alarm controller has two types of controls to
adjust the BGM volume (see figure 25.3). The overall
(maximum) volume of the BGM source is set with the
master volume control, which is located below the BGM
source selector (Select button, see figure 25.1). Per zone
that is connected to the voice alarm controller, the local
volume can be adjusted with the zone volume switches,
which are located below the zone selection buttons
(Zone select, see figure 25.2).
The local volume in the zones that are connected to
voice alarm routers must be adjusted using local volume
controls.
