6.1 Switching ON
To switch on the power, put the Power switch on the
rear of the voice alarm controller (see figure 6.1) in the I
position.
If mains power or back-up power is available, the power
indicator on the front of the voice alarm controller is
turned ON (see figure 6.2).
Note that, on each connected call station, the power
indicator is turned ON (see figure 2.4, no. 7).
6.2 Switching OFF
To switch the system OFF, put the Power switch of the
voice alarm controller (see figure 6.1) in the O position.
6.3 Calibrating the controller
If the system is switched on for the first time and
supervision is enabled, the voice alarm controller must
be calibrated. During a calibration, all loudspeaker line
impedances are measured and stored as reference
values in the controller. These values are used for line
supervision calculations (see section 5.3.3.5). To
calibrate the controller, push the calibration button,
located on the back of the controller (see figure 2.3, no.
24).
6.4 Background music
The background music (BGM) is controlled using the
BGM zone controls on the front of the controller (see
figure 2.3, no. 6). Follow the next steps to distribute
BGM to the zones:
1 Select a BGM source (see section 6.4.1).
2 Select one or more zones (see section 6.4.2).
6.4.1 Selecting a BGM source
Select the BGM source with the BGM source selector
(toggle) button (see figure 6.3). A green LED indicates
which BGM source is selected.
•Select CD/Tuner if a CD or tuner is used for the
background music (see also section 3.7).
•Select AUX if an auxiliary audio source is used for
the background music (see also section 3.7).
6.4.2 Selecting BGM zones
The BGM can be distributed to one or more zones. Use
the Zone select (toggle) buttons (see figure 6.4) to select
the zones. A green Zone select LED indicates if the
corresponding zone is selected.
