8.6.4.1 EMERGENCY UNIT CONFIG
Configuring an emergency unit
Panel for displaying and changing the operating parameters of an emergency
unit.
• Adjusting the sensitivity of the microphone
- Press key 1 - Mic attenuation and hold it down.
- Use the +/- knob to set the required evel of attenuation within a range
from 1 (maximum sensitivity) to 30 (minimum sensitivity).
N.B.: Once the parameter has been set, it is operational both in the Emergency
mode and in the Broadcasting mode.
• Setting the output volume:
- Press key 2 - Output level and hold it down.
- Use the +/- knob to set the required volume level within a range from –6 (minimum output level) to +21 (maximum output level).
N.B.: The parameter set is operational only in the Emergency mode. To set the volume for the Broadcasting mode, see under “AUDIO
SETTING>”.
• Diagnostic settings:
- Press key 3 – Tested cyclically.
> OFF: diagnostics disabled
> ON: diagnostics enabled
N.B.: The addresses of the stations for which diagnostics have been disabled remain in any case in the configuration of the acquired system.
• Setting the 6-zone or 12-zone operating mode:
In a 12-zone system with two VAIE 2250 units connected to one another, it is possible to configure these stations for operation limited to the
6 zones covered by the unit in question or extended to all 12 zones within the system as a whole.
- Press key 4 – Mode cyclically.
> GLOBAL: When a microphone station is in the Global mode, it can be used to make selective announcements or general announcements
in all 12 zones of the system. Access is governed by the priority settings of all the “Global” or “Local” stations connected to the
two VAIE 2250 units.
> LOCAL: When a microphone station is in the Local mode, it can be used to make selective announcements or general announcements
only to the zones covered by the local VAIE 2250 unit to which it is connected. This mode enables another “Local” microphone
station connected to the other VAIE 2250 unit to make announcements to the six zones it covers at the same time. Access
is governed by the priority settings of all the stations connected to the VAIE 2250 unit with which they are associated and to
those of the other VAIE 2250 unit that are set in the “Global” mode.
N.B.: To manage the system correctly, it is suggested that priority levels set for the “Global” microphone bases should be higher than those
set for the “Local” microphone bases. In any case, the VAIE 2250 unit with its own hand-held emergency microphone connected to the front
panel is configured for LOCAL operation and with the highest level of priority, higher than any remote station of the FMD range.
• Setting the level of the 20 kHz test tone:
This control adjusts the level of the 20 kHz test tone generated by the
microphone station so as to offset any losses of the signal in the event of
long-distance connections.
- Press key 6. The line “20 kHz level” will appear, followed by a six-bar
vu-meter showing the value set for the test signal. It is advisable to set
the level in such a way that at least two or three bars of the vu-meter are
active.
- Hold down key 6 and use the +/- knob to set the required level, within a
range from 0 to 200.
N.B. The change in the level shown by the vu-meter will not occur immediately.
After setting the level, wait for about 30 seconds before reading it again.
• Priority
The priority level set for the microphone station is shown on the bottom line to the left. The values can vary between 8 (lowest priority) and
14 (maximum priority). The parameter is displayed only. To change its value, consult the manual of the FMD 2001 and FMD 2012 stations.
• Low Cut Filter
The setting of the LOW CUT filter is shown on the bottom line at the centre.
> LCON: filter active
> LCOFF: filter not active
This parameter is only displayed. To change its value, consult the manual of the FMD 2001 and FMD 2012 stations.
• P.T.T. Toggle
The toggle mode of the PTT key is shown on the bottom line on the right-hand side.
PTT: Toggle OFF
LOCK: Toggle ON
N.B.: The setting of this parameter is operational only in the Broadcasting mode. In Emergency conditions the Toggle mode is always OFF.
This parameter is only displayed. To change its value, consult the manual of the FMD 2001 and FMD 2012 stations.
