TALKBACK PAGING AND BLOCK PAGING
USING ADAPTOR PA-B
1) Up to 10 block or talkback paging areas may be in­
stalled with a system.
For complete and comprehensive installation infor­
mation see instructions packed with PA—B.
2) Amplifier with 70V line output must be used with
adaptor PA—B.
3) One potential phone must be deducted for each PA—B
installed. (If all call is required one additional po­
tential phone must be deducted.
Example #1 shows 3 areas of talkback paging and
all call. Selector button #9 on each phone operates
block #1. Button #12 is used for calling all 3 blocks
simultaneously.
Example #2 illustrates single talkback paging cir­
cuit.
Example #3 illustrates connection if block paging is
desired but without talkback. One amplifier, one
PA—B and one PG—U per block is still required even
though talkback is not required.
