VOICE SYSTEM
4. If no Speaker Group switches are pressed for 120 seconds, the system
automatically returns to normal.
5. Depress the key on the Live Voice Microphone.
6. The LED on the selected Speaker Group switch turns steady green indicat-
ing that the speaker group is now turned on.
7 . Once the microphone is keyed, a preannouncement tone sounds on the
speaker group for approximately 3 seconds (0-10 seconds is programmable
in Zeus).
8. While the preannouncement tone is sounding, the Pre-Announce Tone LED
is on steady to give the operator a visual indication of what is sounding.
9. When the preannouncement tone ends, the Pre-Announce Tone LED turns
off and the Ready to Page LED turns on telling the operator to proceed with
the page.
10. The operator can now speak and make the page to the selected speaker
groups.
11. During the page, the operator can briefly (for up to 5 seconds) unkey and
then re-key the microphone (for example, to cough) - without re-initiating
the pre-announce tone.
12. To end the page the operator simply unkeys and replaces the microphone.
The Ready to Page LED turns off.
13. The Select Page and the selected Speaker Group switch LEDs turn from
steady green to flashing green.
14. To return the system to normal, the operator first depresses the selected
Speaker Group switches, then Select Page. If these switches are not
deselected, the system will return to normal automatically in approximately
1-2 minutes and turn off the Select Page and selected Speaker Group LEDs.
This sequence of operation assumes the system is normal and no alarms exist. If there were
alarms in the system, the Select Page would operate the exact same way - except that the
speaker groups that were receiving an evacuation or alert signal would be overridden by the
page. Once the page ends, the previously sounding evacuation or alert signals would resume
on the floors/groups that were sounding before the page.
Page to Evacuation
Page to Evacuation sends the emergency page message with a single switch press
from the microphone on the LVM to all speaker groups in the system that are
receiving an evacuation signal.
To select Page to Evacuation, follow the steps listed below.
1. The LEDs of the selected speaker groups receiving an evacuation signal are
steady red.
2. Pick up the Live Voice Microphone.
3. Depress the Page to Evacuation switch.
4. The Page to Evacuation switch LED and the LEDs of the selected Speaker
Groups receiving an EVAC signal flash green.
5. Depress the key on the Live Voice Microphone.
