8.9 MANUAL EMERGENCY - < EMERGENCY > MENU
Following is a description of the procedure for managing emergencies manually by an authorised operator.
8.9.1 General information
The manual emergency mode can be accessed at any time. It has priority over any pre-recorded messages being broadcast at the time
activated by an external peripheral unit connected to a “Control Input” and over any emergency units able to cover the six output zones
of the unit concerned. During a Manual Emergency (once access has occurred), the display will show the operating status of the system
as follows:
8.9.2 Recommended procedure for managing emergencies manually
Thanks to its double-channel operation, the VAIE 2250 system enables structured management of the alarm messages, of silencing of
the messages and of selection of the zones, as illustrated in detail below. Following is a list of activities enabling a Manual Emergency
to be handled rapidly.
Zone status bar:
- Empty label: no message being broadcast to this zone.
- EVAC: EVACUATION message being broadcast to this zone.
- ALERT: ALERT message being broadcast to this zone.
- MIC: life announcement being broadcast to this zone with the hand-held
microphone.
- DIS: zone disabled for alarms, cannot be selected (see point 8.6.4).
- FAIL: zone with the speaker line in a failed condition, shown even if the type of failure does not prejudice the output signal being
broadcast, or operating on a single channel due to failure of the amplifier so that the envisaged signal cannot be broadcast to that zone.
For details see points 9.2 and 9.3.
• Led ALARM: LED illuminated to indicate that the VOICE ALARM condition is active when a live announcement or the current pre-
recorded message are being broadcast to at least one zone even if, in a 12-zone system, the zone is covered by the other VAIE 2250 unit
connected via the REMOTE LINK.
Labels associated with zones Z1-Z6:
- Zones with white background: zone non selected.
The current message, if any, has been activated automatically.
- Zones with black background: zone with current message
activated manually.
- Flashing zones: zone selected, ready for a message to be sent
manually or to be Reset (see Note 1).
• Title bar:
- EMERGENCY: access achieved for a manual emergency.
- EMERGENCY UNIT #: on-going manual emergency activated by an emergency unit, with the relevant address, connected to the
EMERGENCY UNIT socket.
- REMOTE UNIT #: on-going manual emergency activated by an emergency unit, with the relevant address, connected to the remote
VAIE 2250 unit, in a 12-zone system.
