Global Audio View
The eight-channel digital evacuation FireFinder-XLS Global Voice system can be added
to the basic FireFinder-XLS fire alarm/mass notification system. This is accomplished
with the addition of the DAC-NET Digital Audio card and its accompanying submodules
(ZAC, LVM/LPB, SCM-8, ZIC, FMT, TZC-8B, NRC) and zone-installed equipment (speak-
ers, strobes, telephones). Figure 5-1 is a block diagram of Global Audio.
The system is capable of automatically or manually signaling to its installed speaker
zone circuits (ZAC). The signal can be up to eight channels of prerecorded messages
and/or tones including up to two simultaneous channels of live paging. The tones and
prerecorded messages are configurable in the Zeus programming tool and are
available for upload to each installed DAC-NET. A maximum of 32 DAC-NET modules
can be installed in each FireFinder-XLS system. Each DAC-NET may input either its
own tone/message to a channel, or it may be programmed to use a tone/message
from a DAC-NET designated as the Global Audio source.
Individual zone circuits (speaker, strobe, telephone) are bundled into geographic
groups during system configuration. These groups are either automatically controlled
by pre-programmed system logic, or manually controlled by the switches located on
one or more Command Stations. Paging, manual control, or monitoring of the
speaker or telephone groups can be performed from any location where an LVM/LPB
microphone, SCM switch control module, or PMI/PMI-2/PMI-3 is installed.
