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, and at the programmed speaker
group control switch. The operator at the PMI 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 comes on and the Silence Audibles soft key displays on the
PMI so the system can be silenced from the PMI.
The 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.
