Attention! The text in this document has been recognized automatically. To view the original document, you can use the "Original mode".
DUE TO THE ADVANCED DESIGN OF THE PA-1 AND PA-2 BLOCK PAGING ADAPTORS, SEPARATE
CHANNELS MAY BE ESTABLISHED FOR PAGING OR PAGING WITH TALKBACK TO ANY NUMBER OF BLOCKS.
COMBINATION OF STRAIGHT PAGING AND TALKBACK PAGING
1) One potential phone must be deducted for each PA-1
or PA-2 installed.
2) One amplifier must be used with each PA-1 or PA-2.
3) Only one background music source, if used, is required
for entire system.
This example shows one area of talkback paging (block #1)
and two areas of paging without talkback (block #2 and
#3).
Selector button #10 on each phone operates block #1,
selector button #11 operates block #2, and selector
button #12 operates block #3.
This is a multi-channel paging system meaning more than
one paging operation may take place at the same time.
For full information please refer to instruction sheet
packed with the PA-1 or PA-2.
