1.
Set the "Zone Amplifier/Central Amplifier" select switches for each group as required. See switch symbol 1 . If a group is using a zone amplifier
or speaker amplifier, then that group's switch should be in the down position. If a group is using a central amplifier, then that group's switch should
be in the up position.
2.
Set the "Central Amplifier" select switch for each group, as required. See switch symbol 2 . If one central amplifier is used for both paging and
background music, then the switch should be in the down position. If two or more central amplifiers are used, one for paging and one or more for
background music, then the switch should be in the up position. If central amplifiers are not used, then the switch should be in the up position.
3.
Set the "One-Way/Talkback" select switches for each zone as required. See Switch symbol 3 . If a zone is to have talkback paging, then that
zone's switch should be in the up position. If a zone is to have one-way paging, then that zone's switch should be in the down position.
NOTE: All zones in groups using (selected for) zone amplifiers or speaker amplifiers are one-way paging zones. Hence, the individual zone
switches should be in the down position. Zones selected for talkback paging must be in groups selected for central amplifiers - See switch symbol
