5.5 12-ZONE SYSTEM
5.5.1 Connection
Example of connection of two VAIE 2250 units so as to configure a system with a total of up to 12 zones, using the REMOTE LINK. It is
also possible to add to each VAIE 2250 unit its own optional MPA 5240 amplifier for increasing the output power up to a total of 980 W.
As far as concerns sizing and the settings for each VAIE 2250 unit, reference should be made to points 5.1.1 and 5.1.2.
Basically, the two units function as two separate systems covering six zones each, but which share the generic signalling referred to
their operating conditions for the “Failure”, “Alarm” and ”Disabled” status affecting the system as a whole.
With the addition of a FMD 2001 or FMD 2012 remote microphone station, connected to an EMERGENCY UNIT socket and set in the
GLOBAL mode, it is possible to send out alerts and emergency messages throughout the 12 zones. For the settings see point 8.6.4
It is also possible to broadcast announcements selectively to the 12 zones via the MBT 1112 PAGING UNITS.
After making the connection via the REMOTE LINK, the two VAIE 2250 units configure
themselves automatically without making any other settings. The logo “12” will appear
in the top right-hand corner of the main page of the MUSIC Menu of each VAIE 2250
to indicate that the system is configured for 12 zones (see figure opposite).
Should the REMOTE LINK be broken off, both VAIE 2250 units will signal the failure
as a “Remote Link Fault”. To restore the standard 6-zone configuration, RESET the
configuration as illustrated in point 8.6.6.2 “Restoring the 6-zone configuration” on
page 8-26.
N.B.:
Use Cat. 5e SF/UTP cable with a braided
shield for connecting the two VAIE 2250
units and PAGING UNITS to one another.
Maximum length of the connecting
line: 1km.
5.5.2 Assigning the output zones to the selection controls
• VAIE 2250 Units
The six numerical keys on the control panel of each VAIE 2250 affect only their respective output zones, so that the two units function
basically as two separate systems covering six zones each.
• FMD 2001 and FMD 2012 remote emergency units
By connecting one or more remote emergency units to the EMERGENCY UNIT sockets, it is possible to achieve complete management of
the 12-zone system. The emergency units can function either in the “Local” mode or in the “Global” mode, thus adapting them to various
different needs according to the emergency plan. A station in the LOCAL mode can only access the six output zones covered by the VAIE
2250 unit to which it is connected, while a station in the GLOBAL mode can access all 12 zones of the system. For further details on the
station programming modes, see point 8.6.4. Model FMD 2001 has only the PTT key assigned to general switching (it may be programmable)
and the programmable AUX key for sending pre-recorded messages to a pre-defined set of zones. In addition to all the functions available
on the FMD 2001, model FMD 2012 also has a selection keypad with 12 keys, each of which has 3 LEDs for signalling the various operating
statuses of the relevant output zones.
