6-4 GCNET and Galactic Voice
FIREFINDER-XLS INSTALLATION, OPERATION AND MAINTENANCE MANUAL | CHAPTER 6
Automatic Operation The Global Voice system interfaces automatically to the fire alarm system using the
speaker functions in the Function view of the Zeus programming tool. In reaction to
events from the fire alarm system (DLC devices), the voice alarm system activates its
pre-programmed alarm procedures. Typically, the voice alarm system broadcasts an
alarm signal, which is immediately followed with a prerecorded message on the fire
floor, the floor above, and the floor below. It is common to have two stage alarms,
with evacuation in some areas and alert in others. LEDs indicate the current system
status and the floors in which the evacuation or alert signal is sounding.
Since this sequence has occurred automatically, only the events that were predeter-
mined in the original system evacuation plan and programmed into the system
configuration program will occur.
Evacuation Signal (EVAC) A steady red LED indicates that an evacuation signal (tone or message) is being sent
to the entire building or to selected areas of the building requesting that the occu-
pants evacuate. It is possible to have two different evacuation signals, EVAC 1 and
EVAC 2. EVAC 2 will be overridden by EVAC 1 to the same speaker group.
Alert Signal Alert signal sends the alert tone or message (predetermined in system design) to all
or selected speaker groups in the building. The alert signal will be overridden by an
emergency page or an evacuation signal to the same speaker group.
A flashing red LED indicates that an ALERT signal (tone or message) is being sent to
the entire building or selected areas to alert occupants. It is possible to have two
different alert signals, ALERT 1 and ALERT 2. ALERT 2 will be overridden by ALERT 1
to the same speaker group.
Manual Operation After a few minutes of automatic operation, the voice alarm system can be taken
over manually by authorized personnel.
Manual voice operation functions such as emergency paging, evacuation or alert
signal activation, firefighters' telephone operation, multiple voice system command
center operation, as well as convenience page or background music operation are
possible at any time.
Emergency Page Emergency Page allows a live voice page from the emergency microphone to all or
selected speaker groups in the building. An optional preannouncement tone pre-
cedes emergency pages for a duration of time set in the Zeus programming tool.
SYSTEM PRIORITIES The priority of requests to a speaker group in the case that multiple signals (audio
channels) are requested at the same time are as follows:
1. Emergency Page (highest priority)
2. Evacuation Signal 1 (EVAC 1)
3. Evacuation Signal 2 (EVAC 2)
4. Alert Signal 1 (ALERT 1)
5. Alert Signal 2 (ALERT 2)
Galactic ALL applications (such as Galactic All Evac 1) apply the application to all
speaker groups across all Buildings throughout the site.
