OPERATING CONDITIONS AND TERMINOLOGY
UK
C3. ALERT button Key for sending pre-recorded Alert messages manually, operation during Manual Emergencies. In the idle condition
this key is not operational.
C4. EVAC button Key for sending pre-recorded Evacuation messages manually, operational during Manual Emergencies. In the idle
condition this key is not operational.
C5. MENU key Multi-purpose key for accessing the Main Page, for navigating among the menus and for specific functions of the
submenus indicated on the display.
C6. OK key Multi-purpose key for confirming selections, for navigating among the menus and for specific functions of the submenus
indicated on the display.
C7. ESC key Multi-purpose key for returning to the Music menu, for navigating among the menus and for specific functions of the
submenus indicated on the display.
C8. Numerical keys from 1 to 6 Multipurpose keys, operational throughout the system. These keys are used to select the zones, from
1 to 6. For the VAIE 2250 unit being used. They enable the access password to be entered or the specific functions indicated on the
status bar on the display to be applied.
C9. Status signalling
• ALARM LED (red)
LED for signalling the existence of a “Voice Alarm Condition”. A VOICE ALARM condition can be activated both automatically from
an external peripheral unit, and manually by the operator of the VAIE 2250 or of an emergency microphone station. When the LED
is illuminated steadily, this indicates that a pre-recorded or live emergency message is being broadcast to at least one zone (of the
whole system, also when it includes 12 zones). During the VOICE ALARM condition, the standard functions for playing out music
and the voice source service are disabled. In the “Quiescent condition” the ALARM LED is extinguished.
• FAULT LED (yellow)
LED for signalling the existence of a “Fault condition”. This indicates that the diagnostic system has detected at least one failure in the
VAIE 2250 unit or in one of the items of equipment connected to it and covered by the diagnostic procedure. When the fault condition
is cleared, the FAULT LED extinguishes automatically and the wording “RES” is shown on the FAULTS display, to show that a failure
has been detected and subsequently remedied (RESOLVED). The LED signalling that the fault has been cleared will extinguish
once the MANUAL FAULT RESET procedure has been completed. In a 12-zone system with two VAIE 2250 units connected to one
another, if the LED flashes, this indicates the presence of at least one current failure referred to the other remote VAIE 2250 or to an
item of equipment connected to it and covered by the diagnostic procedure.
• DIS. LED (yellow)
LED for signalling activation of the disablement of the emergency zones (DISABLING). The DISABLING signal indicates that at least
one zone has been disabled by the emergency envisaged when configuring the system. Activation of the DISABLING signal does
not prevent normal operation of the system in a “Quiescent Condition”.
• SYS LED (yellow)
LED for signalling an existing “System Fault” (System CPU Fault) condition. When the SYS LED is illuminated, all the operational
functions, whether of the standard or emergency type, are disabled. When the VAIE 2250 is switched on, the SYS LED will flash to
show that the system is being started up.
• BATT. LED (green)
This LED refers to the 24 VDC auxiliary power supply. The BATT. LED lights up to indicate that the 24 VDC power supply is connected
to the system.
• ON LED (green)
This LED signals that the VAIE 2250 system is switched on and operational.
The ON LED continues to be illuminated when:
- 230 VAC power supply present and POWER switch in the ON position.
The ON LED will flash continuously when:
- there is no 230 VAC power supply but the 24 VDC power supply is available.
The ON LED will be Off in the following cases:
- no 230 VAC and no 24VDC power supply, or
- 230 VAC power supply in order, no 24 VDC power supply and POWER switch in the OFF position.
C10. +/- knob This is a rotary control with no end-of-travel. It is a multi-purpose control that depends on the specific menu that is
operational. It is used to move the cursor to select and adjust values. In an idle condition, in the Music menu it is used to control
directly the master output volume of the BGM.
C11. “EXT.” USB socket This is a powered type A USB socket for plugging in external flash memory devices. It enables .mp3 music
files to be played out directly using the controls of the USB Music menu. It also enables *.WAV files containing Chime tones and pre-
recorded Alert and Evacuation messages to be transferred to the memory residing in the VAIE 2250, during checking and diagnostic
procedures. To load the files, refer to the procedures illustrated in the CHIME and Messages menus.
C12. “TO PC” USB socket Type B USB socket, provisions for connecting the management PC in order to use the system software.
