5.1 A 4481 PAGING CONSOLE
The A 4481 paging console is an extremely flexible addition to the A 4480B audio switcher.
The consoles can be used for multi zone paging with the facitily to store and recall multiple zones to a single button. The
recall functions can also be labelled via a USB keyboard which can be plugged into the rear of the unit. (see section 5.1.4)
The labels will then be displayed on the highly functional and attractive LCD. An example might be a label “sales”.
An emergency paging over-ride facility is accessed by a combination of an illuminated push button switch and a PTT (push
to talk) switch. This combination removes the possibliity of accidentally activating the emergency over-ride facility. When
activated, emergency paging will be forced through to all zones regardless of any zones which were set to be locked out.
A maximum of 8 paging consoles can be connected to the A 4480B at the same time. These work on a “first in, best
dressed” arrangement. The consoles can be cascaded together or wired back to the A 4480B (see section 5.1.3 to 5.1.5
for details).
Each unit must be assigned an ID number through DIP switch settings on the rear of the unit.
A pre-announcement chime is available at the paging console and through the PA system. Both of these are set by DIP
switches on the rear of the unit.
