VOICE SYSTEM
Figure 4-1
Typical FireFinder-XLS Command Station
A voice system may have one or more different locations of control over the same
installed equipment. Each control station will generally use Request/Grant/Deny
Access switches for managing controls in emergencies, but access restrictions are
Zeus-programmable to the degree allowed by the authority having jurisdiction (AHJ).
A location of voice system control (command station) consists of the following:
1. A list of Speaker Groups to be controlled/monitored.
2. A set of Voice Applications to be performed on the Speaker Groups (for
example, ALL CALL, SELECT EVAC, DISPLAY ALERT, etc.).
3. An LVM microphone.
4. An optional list of telephone groups and an FMT master phone.
5. Request/Grant/Deny access.
All voice system faults are reported at the PMI/PMI-2/PMI-3, and at the programmed
speaker group control switch. The operator at the PMI/PMI-2/PMI-3 is able to ACK,
SILENCE/UNSILENCE and RESET voice system events. For example, in the event of
an ALL EVAC, the Audibles LED on the PMI/PMI-2/PMI-3 comes on and the Silence
Audibles soft key displays on the PMI/PMI-2/PMI-3 so the system can be silenced
from the PMI/PMI-2/PMI-3.
The voice system interfaces automatically to the fire alarm/mass notification system
using the speaker functions in the Function view of the Zeus Programming tool. In
reaction to events from the fire alarm/mass notification system (DLC devices), the
voice alarm system activates its pre-programmed alarm procedures. In fire applica-
tions, the voice alarm system typically broadcasts an alarm signal, which is immedi-
ately 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.
