Installation (Continued)

Hub Options

The intercom hub has two banks of
dipswitches. One bank enables or
disables each door station's door
release button. The other bank
enables or disables each door or
patio station's privacy mute and do-
not-disturb feature.
Select the options appropriate for
the installation. The numbers on the
dipswitches correspond to the hub's
station numbers. Mark the switch
settings in the log on Page 17.

Hub Power Supply Connection

The switching power supply module
included with each hub powers the
hub and all stations connected to
it. If an expansion hub is used, it
requires its own power supply.
Place the power supply in the
enclosure with the hub. Insert the
power supply output plug into the
hub's POWER jack. Insert the power
supply's power cord into the 117 VAC
outlet installed in the enclosure.

Hub Status Indicators

When the hub powers up, a
diagnostic check is run for all the
stations connected. On the hub, the
green indicator above the station's
connector will light and stay lit for
all stations that pass the diagnostic
check (also for the optional expansion
hub). If any hub indicators do not
light, check the wiring associated
with that connector.
The diagnostic check only occurs
when power is applied to the hub.
To perform the diagnostic check at
any time, cycle the hub power off
then on again.
