Note that if multiple outputs are needed to fulfil the power requirements, it is recommended to name lines to same. For
additional information, see the section “Locked Group”.

Transfer line voltage level is only informative. Real selection needs to be done with hardware.

LINE TRANSFER CTRL mode:

Priority

→

 +24V priority voltage for announcements

Spare amp

→

 spare amplifier control to be used with AAC 200 module

Locked Groups

When more than 120W of amplifier power is needed, outputs can be set to Locked Group. This will lock 2-4 outputs to
work as a one output with power of 240-480W (max. 350W without external power supply)

In the example window above outputs 6, 7 and 8 is chained together working as a Locked Group named “Line 6”. The
total output power for this line is raised to be 360W.

How to connect the line is described in the section LINE TRANSFER: Locked Group.

Note  It is very important to configure the Locked Group carefully for proper function of the system!

Allow Standby Switch

Enables front panel stand-by switch. It is not recommended to enable stand-by switch for monitored voice evacuation
systems.

4.3.3 Definition of Announcement Characteristics

Paging Zones

Choose from Define System menu “Paging Zones” or select icon

It will open a window to manage paging zones.
