• MBT 1106 and MBT 1112 broadcasting microphone stations
By connecting one or more remote paging units to the PAGING UNIT socket, it is possible to manage the whole 12-zone system for
broadcasting announcements.
Model MBT 1106 has six zone-selection keys that can be assigned only to the six output zones of the “local” VAIE 2250 unit to which the
station is connected. The PTT key (which may be programmable) functions in the GLOBAL mode and is assigned to selecting all 12 zones;
model MBT 1112 functions in the GLOBAL mode and has 12 zone-selection keys that can access all 12 zones of the system.
The zone-selection keys and their LEDs are assigned to the output zones of the system with reference to the VAIE 2250 unit connecting
them to the microphone station:
- The first zone-selection group, numbered from 1 to 6, is assigned to the output zones of the “local” VAIE 2250 unit to which the station
is connected.
- The second zone-selection group, numbered from 7 to 12, is assigned to the output zones of the “remote” VAIE 2250 unit, connected
to the “local” VAIE 2250 unit via the REMOTE LINK.
The zone-selection keys can also be programmed to activate a group of several output zones (see the User Manual of the station), in which
case the LEDs corresponding to the actual zones activated will light up both at the time of selection and at the time of the announcement.
The figure shows how the zone-selection keypads are used.
The signalling LEDs of the zone-selection keypad are assigned to the output zones of the system with reference to the VAIE 2250 unit
connecting them to the microphone station:
- The first group of LEDs of the zone-selection keys numbered from 1 to 6, is assigned to the output zones of the “local” VAIE 2250 to which
the station is connected.
- The second group of LEDs of the selection keys numbered from 7 to 12 is assigned to the output zones of the “remote” VAIE 2250 unit,
connected to the “local” VAIE 2250 unit via the REMOTE LINK.
The zone selection keys can also be programmed to activate a group of several output zones (see point 8.6.4.1, page 8-24). In this case:
- When a zone is selected, the green LED corresponding to the chosen key will flash to indicate that the selection has been made.
- When the output signal is activated, the LEDs corresponding to the actual zones activated will light up on the basis of the current status.
