Controls
The 2-Wire Intercom Type Select Switch determines the type of 2-Wire intercom that may be
connected to the corresponding 2-Wire connectors on the rear panel of the BaseStation. Clear-Com,
RTS, or BAL (AudioCom) can be selected. These switches only affect 2-Wire operation and do not
control 4-Wire operation. The CHAN A&B switch selects the 2-Wire system type for both the A and
the B intercom channels.
The Intercom Channel Select (SEL) button selects one of the two intercom channels to allow
selection of 2-Wire or 4-Wire functionality and to allow the intercom audio IN and OUT levels to
be adjusted.
Pressing the Intercom Channel Select button once selects Menu Mode on the BaseStation and
displays the Intercom Levels screen on the LCD display. A second press selects channel A. The
intercom channel selected is indicated by one of the two CHAN LEDs located to the right of the
CHAN SEL button and on the LCD screen. Additional presses of the CHAN SEL button advances
through the remaining intercom channels. The next press of the CHAN SEL button will exit Menu
Mode and will cause all of the LEDs to be illuminated.
The 2-Wire/4-Wire Select (SEL) button selects the connection mode for operation of each
of the two intercom channels. Pressing the 2-Wire/4-Wire Select (SEL) button changes the
selected intercom mode between 2-Wire, 4-Wire or no wired connection. In Operational
Mode, the four 2-Wire/4-Wire LEDs indicate the currently selected hardwired intercom
connection mode for each of the intercom channels: 2-Wire, 4-Wire, or no wired intercom
connection.
The IN and OUT controls adjust the intercom volume level coming in to the Tempest BaseStation from
the hardwired intercom system or out to the hardwired intercom from the BaseStation. In addition,
these knobs adjust Aux IN/OUT levels.
To adjust the levels press the CHAN SEL button to enter Menu mode, CHAN SEL again to advance
to the desired channel and rotate the IN or OUT controls. Note that the LCD display indicates the
currently selected levels.
Intercom Channel volume levels are expressed in Decibels (dB):
» IN: -10.5 t5.5
» OUT: -10.5 t5.5
Always set the 2-Wire Intercom Type Select Switches prior to connecting the 2-Wire
intercom to the back of the Tempest BaseStation. Never change the switch setting while
connected to a wired intercom system. Failure to follow this procedure could damage the
Tempest BaseStation or the 2-Wire hardwired system.
The IN and OUT controls are only active in Menu Mode.
