5. OPERATING CONDITIONS AND TERMINOLOGY
5.1 GENERAL DEFINITIONS
Following is a list of the signalling modes of the operating conditions of the system and of definitions used in the rest of the manual, completed
by indications of a general nature:
5.1.1 Signalling of operating conditions
The VAC 2006 system is structured to signal the different operating conditions on the basis of the following definitions:
“
Q
uiescent condition” (ALARM – FAULT – DIS – SYS LEDs extinguished)
Normal operating condition, with no current failures or emergencies. This status enables the sources of music and voice to be managed for
service announcements.
“A
larm Condition” (ALARM LED illuminated)
This operating condition signals the current presence of at least one alarm signal, either pre-recorded or live, on at least one output zone. The
“Alarm Condition” can be activated in the form of an Automatic Emergency from an external peripheral unit connected to the Control Inputs or of
a Manual Emergency through an authorised operator. During an “Alarm Condition”, the functions of the music sources and of the voice services
referred to the quiescent condition are not operational.
“
F
ault warning condition” (Led FAULT)
Operating condition signalling the presence of at least one on-going failure, detected by the internal diagnostics system causing the FAULT
LED to light up steadily.
In the event of failure of a remote controller, the FAULT LED will flash.
It is accompanied by an acoustic signal (buzzer) indicating the failure. Depending on the causes of the failure, the system may in any case
p
e
rform the functions relating to the “Quiescent” and “Alarm” conditions.
“System Fault” (SYS LED illuminated)
This operating condition signals that the system is blocked as the result of a temporary or permanent malfunctioning of the CPU, detected by the
wa
tchdog. It is accompanied by an acoustic signal (buzzer) indicating the failure. During a System Fault, the functions relating to the “Quiescent”
and “Alarm” conditions are not operational.
“Dis
ablement condition” (DIS LED illuminated)
This operating condition signals that the Alarm signals for at least one output zone have been set to a Disablement condition. The system can
in
any case carry on the functions pertaining to the “Quiescent” condition for all the zones and, only for those zones that are not disabled, the
functions pertaining to the “Voice Alarm Condition”.
“A
utomatic Emergency” (CONTROL INPUT STATUS Display with zones active)
This indicates a sequence of operations performed from an external peripheral unit connected to the Control Inputs. Depending on how these
inputs are programmed, the “Voice Alarm Condition” or an Alarm Reset are activated.
“M
anual Emergency” (LED of the EMERGENCY button ON/flashing)
This procedure is performed by an authorised operator using the manual controls, to activate Emergency sources or to reset the Alarms (Manual
Alarm Reset). The operations carried out in the Manual Emergency mode have a higher priority than those activated by an Automatic Emergency.
A VAC 2006 unit or an emergency unit on which the EMERGENCY LED is illuminated is enabled for use for activating Emergency sources or
for resetting the alarms. A VAC 2006 unit or an emergency unit on which the EMERGENCY LED is flashing indicates that a Manual Emergency
has been activated from a remote station.
5.1.2 Glossary
Following is a list of definitions of terms used in this manual, completed by indications of a general nature.
“BGM Source”:
One of the following audio sources using the “Music” amplification channel (BackGround Music):
-
A
udio source connected to the AUX input.
- Flash memory device containing *.mp3 files plugged into to the front-panel USB EXT socket.
- Sorgente audio collegata all’ingresso IN 1 (Microfonico) con modalità impostata MODE: IN OFF.
- Sorgente audio collegata all’ingresso IN 2 (Microfonico oppure di Linea) con modalità impostata MODE: IN OFF.
During a “Voice Alarm Condition”, the BGM sources are not operational.
“PA Source”:
One of the following audio sources using the ”Voice” amplification channel for Public Address announcements:
-
S
ource of sound connected to the IN 1 input (Microphone input), set in the ON or PRECEDENCE MODES.
- Source of sound connected to the IN 2 input (Microphone or Line input), set in the ON, VOX or PRECEDENCE MODES.
- EMERGENCY UNIT in the broadcasting mode, PAGING UNITS.
During a “Voice Alarm Condition” the PA sources are not operational.
