USING THE SYSTEM
UK
8.5.2 IMP. REAL TIME
Real-time line impedance
Panel for checking the impedance values measured in real time, and
percentage variations from the value stored during start-up, using the
“Line impedance acquisition” procedure. The 6 zones are listed, with
their impedances, measured in Ohms. The measure indicated is referred
to both lines - A and B - connected to the zone output. If the percentage
of variation exceeds the level of tolerance set at the time of configuring
the system, a “LOUDSPK LINE FAULT” due to an excessively high or
low impedance (Impedance Hi or Impedance Low) will be signalled.

8.5.3 CHECK MESSAGES
Diagnosis of stored messages
Panel for checking all stored data for each of the emergency
messages. Referring to the two messages EVAC and ALERT, it
shows the checksum data in alphanumeric format (see example in
the figure). A different checksum data is generated when the new
message is stored.
Press ESC to return to the INSPECTION panel.
Note: if several input contacts are activated simultaneously, with
different programming of the messages in relation to the zones, for
each zone output the system will enable the event with the highest
priority (see table below). The CONTROL INPUT STATUS panel will
therefore show the zone outputs as configured following enabling of all
the active contacts:
8.5.4 CONTROL INPUTS STATUS
Status of the local input contacts
Panel for viewing the status of the local input contacts (CONTROL
INPUTS). A list of the input contacts activated by external peripheral
units is provided. The CONTROL INPUT STATUS panel shows
the active inputs, both if no events are associated with them and
if an output message event is associated with them. In the event
of activation of a programmed CONTROL INPUT, the VAIE 2250
system will trigger an “Alarm Condition” (VOICE ALARM), cause the
ALARM LED to light up and the CONTROL INPUT STATUS panel
to be displayed automatically. The display will show a list of all the
active inputs (whether programmed or otherwise) and will indicate
the type of pre-recorded message being output to each zone. In
the event of an active input contact programmed for a GENERAL
RESET, the ALARM LED will be extinguished.
For further information concerning programming, consult point 8.6.1, OPERATOR / Set> CONTROL INPUTS. For details on activity in
the “Voice Alarm Condition”, consult point 8.8 AUTOMATIC EMERGENCY – Voice Alarm Condition.
Press ESC to return to the panel INSPECTION.
8.5.5 INDICATORS TEST
Check of the functionality of the visual
and audio signal elements
Panel for checking speaker functionality (BEEP),
display and operating emergency LED indicators. All
LEDs on the front panel (excluding ‘ON’ LED) and
the EMERGENCY key LED are flashing. Horizontal
bar scrolls on the display and beep warning tone
are ON.
The functionality of the built-in speaker, all LEDs and
all the display pixels are checked. Please contact
Support in case of failure. Press ESC to return to
the INSPECTION panel.
Maximum priority General reset of messages (RESET)
High priority
Pre-recorded Evacuation message (EVAC)
Low priority Pre-recorded Alert message (ALERT)
Minimum priority No event (NONE)
