5.1.5 Cascading the paging consoles with 8 zone wallplates and a preset plate.
The situation may arise where all 8 zone wall plates, a preset wallplate and two or more paging consoles are required.
In this case the configuration shown in Fig 5.1D may be used. In this figure six paging consoles have been connected to
ports 1-3. This is the maximum number of paging consoles allowed in this configuration. The A 4476 preset wallplate may
be connected to any of the paging console inputs or any zone wallplate input. Note that each paging console must be
assigned an ID number before operation (see 5.1.2 DIP switch 4). In cascade operation, each A 4481 paging console must
be powered by individual 24V DC power supplies (Altronics part: M 8968C).
Peripheral Connections
5.1.6 Multi-zone paging
Paging is achieved by pressing the numbered button of the zone required. The button will illuminate. Hold down the page
switch and speak into the microphone. Note: a zone with a fast flashing LED has general paging blocked. To page to
multiple zones, press the buttons for the desired zones. Multiple buttons will illuminate. Hold down the page switch and
speak into the microphone.
5.1.7 Zone lock out
General paging can be blocked to any zones either at the A 4480B main unit or via the paging consoles. To block paging
to a zone from the A 4481, hold down the desired zone button until a message on the LCD indicates the zone is blocked
out. Release the button to resume. To unlock the zone, repeat the procedure.
