GLOBAL VOICE 5-1
INTRODUCTION A FireFinder-XLS system can be either a Single Node Voice system (as described in
Chapter 4) or a Global Voice system. For a Single Node Voice system, multiple
command stations (an Autonomous Control Unit [ACU] in Mass Notification systems)
are controlled by a single PMI/PMI-2/PMI-3. The Global Voice system is a network of
multiple voice systems that can be controlled throughout the system from a single
point. It also enables voice control, paging and synchronized audio between multiple
XLS nodes. Zeus Version 7.0 or higher is required for a Global Voice system. An XLS
network cannot contain both Single Node Voice and Global Voice.
A Global Voice system supports five Global Command Stations per network. Global
Command Stations allow annunciation and control over phone and speaker groups
across all FireFinder-XLS nodes in the system. There are two types of Global Com-
mand Stations: Primary and Secondary.
• Primary Global Command Stations require coverage of all speaker and
phone groups across all FireFinder-XLS nodes in the system.
• Secondary Global Command Stations allow a selectable group of speaker
and phone groups. The groups are selected using the Zeus tool.
Global Command Stations may also have “Global All” applications and related global
control switches.
FMTs and LVMs are allowed only in Global Command Stations. A maximum of 59
DAC-NETs can be networked together across XLS nodes. Each DAC-NET is controlled
by and associated with their own parent PMI/PMI-2/PMI-3 (one DAC-NET per PMI/
PMI-2/PMI-3). There can be a maximum of 10 Global PMI/PMI-2/PMI-3s.
Global Command Stations are unrelated to Global PMI/PMI-2/PMI-3s. In Global Voice
only, each PMI/PMI-2/PMI-3 node does not need a command station. However, at
least one Primary command station (ACU in Mass Notification systems) is required in
each Global Voice System.
The most important difference in the system configuration between Single Node
Voice and Global Voice is that in a global system, there is one DAC-NET per PMI/
PMI-2/PMI-3. The DNET between all DACs is connected. Also note that XLSV nodes
must be networked in a ring using NRCs. These NRCs are to be used in place of XNET
NIC-Cs.
Global Voice cannot be used on hybrid systems (those with MXL, MXL-IQ or MXLV).
Some features are not available before Zeus 8 or 9.
