5.6.5.2 Select zones

Select the zones to which the live speech must be

distributed with the Zone select buttons on the front of

the voice alarm controller (see figure 5.12). A red LED

indicates the zones to which the live speech is

distributed.

• If the indicator of a Zone select button is off, the

zone is not selected. Push the button to select the

zone.

• If the indicator of a Zone select button is on, the

zone is selected. Push the button to deselect the zone.

To select all zones, push the All call buttons on the front

panel of the voice alarm controller (see figure 5.13).

5.6.5.3 Make the announcement

Push the push-to-talk (PTT) button of the emergency

microphone to make an announcement (see figure 5.14).

The live speech is only distributed to the selected zones

(see section 5.5.2). At the moment the PTT button of the

emergency microphone is pushed:

• The red EMG mic indicator is lit (see figure 5.15).

• If they are currently distributed, the default alert

message and default alarm message are stopped.

Note

If no additional action is taken within 10

seconds after the last Zone select button has

been pushed (for example closing the PTT

switch), the zone selection is cancelled.
