Controls

The two 2-Wire Intercom Type Select Switches determine 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 CHAN C&D switch selects the 2-Wire system type for both the

C and the D intercom channels.

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 Intercom Channel Select (SEL) button selects one of the four 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 four 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 four 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 eight 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):

2-Wire IN: -13.5 to +10.5

4-Wire IN: -18 to +4

2-Wire OUT: -10.5 to +7.5

4-Wire OUT: -6 to +12
