USING THE SYSTEM
UK
8.8.1 Activation of an Automatic Emergency
In the event of activation of a programmed local input contact, the
VAIE 2250 system will suspend its normal activity typical of the
“Quiescent condition”, stop the music being broadcast, inhibit the
functions of the PA sources for broadcasting announcement and
show the “CONTROL INPUT STATUS” panel.
If the contact has been programmed to send at least one emergency
message to at least one output zone, the system will initiate the
Automatic Emergency by enabling a “Voice Alarm Condition” and
causing the ALARM LED to light up. The display will therefore show
a list of all the active inputs (whether programmed or otherwise)
and will indicate the type of pre-recorded message on the outputs
for each zone.
If the contact has been programmed for a GENERAL RESET, the
system will start the Automatic Emergency and show the “CONTROL
INPUT STATUS” panel, leaving the ALARM LED extinguished.
8.8.2 Operation of the system during Automatic Emergency
As long as the input contacts are active, the MUSIC panel will remain inactive. It will, however, be possible to navigate among the
various menus to access the advanced functions of the system and to investigate or change the settings.
• Press the ESC key.
To access the MAIN page and inspect the other management menus.
A current “Voice Alarm Condition” due to an Automatic Emergency may be altered by an authorised operator entering the system to
activate the manual controls for managing the emergency, in order to RESET the messages, change the current messages or send
live announcements using the microphone provided for this purpose.
For details about management of a Manual Emergency, consult the MANUAL EMERGENCY Section, point 8.9.
• Exiting from an Automatic Emergency:
• De-activate all the contacts of the external peripheral unit.
In order to signal the operator that an activation has occurred by external contacts, the system maintains the INPUT STATUS CONTROL
status display panel (input with no contact and no zone alarm activated).
• Press the ESC key.
The system will return to a Quiescent condition, showing the MUSIC panel.
8.8 AUTOMATIC EMERGENCY - ALARM CONDITION ACTIVATED FROM AN EXTERNAL PERIPHERAL UNIT
Following is a description of the operating mode of the system in the event of an Automatic Emergency initiated by an external peripheral
unit activating the input contacts programmed to enable a “Voice Alarm Condition”.
Viewing the operational status:
ALARM LED: This LED lights up to indicate that a VOICE ALARM is active when a live microphone announcement or a pre-recorded
message are being sent out to at least one zone. In a 12-zone system, the ALARM LED will light up on both VAIE 2250 units, regardless
of the active output zone.
Display:
In proper operating conditions with a dual channel, the display will show t he number of contacts activated, as illustrated in the figure. In
the event of a failure of an amplifier, on the other hand, the display will show the following message:
“Only one channel available - FAULT CONDITION” to indicate operation on a single channel.
Zone status bar:
- Empty label: zone without any current message
- RESET: zone mute due to general reset contact
- EVAC: zone with EVACUATION message being broadcast
- ALERT: zone with ALERT message being broadcast
- DIS: zone in which alarms are disabled (see point 8.6.4)
- FAIL: zone with failure condition on the speaker line. Label shown even if the type or failure does not prejudice the outgoing signal.
When operating on a single channel due to an amplifier failure, this indicates that the zone is unable to broadcast the planned signal.
For details see points 9.2 and 9.3.
For details about the messages displayed, consult point 8.5.4 INSPECTION / CONTROL INPUT STATUS and for details about
programming consult point 8.6.1 OPERATOR / Set> CONTROL INPUTS.
