Description
The WM1000 and WM2000 Intercom Stations are designed for stationary, wall-
mounted installation in standard two-gang electrical boxes. The WM1000 is a
single-channel station; the WM2000 provides switch-selectable access to either of
two intercom channels. The WM1000 and WM2000 are ideal when users need to ac-
cess the intercom system from strategic locations where a desktop station would be
unsuitable, but they do not wish to carry around a belt-pack station. Since all of the
intercom electronics are in the intercom station, the user need only connect a headset
or telephone style handset to begin communicating. Alternatively, a headset or tele-
phone handset can be left at the station.

lists the
switch descriptions and factory default settings. Figure 1 shows the locations of the
switches.
DC Call Enable (DIP Switch 2)

By default, incoming calls are indicated by a red-flashing Call key and a beep tone in
the headphones. If you do not want the beep tone, set DIP switch 3 to the closed position.
Headset Microphone Type Selection (DIP Switch 4)
If the headset specifications indicate the microphone type is balanced, or if you are
unsure, leave this switch in the open (default) position. If the specifications indicate
an unbalanced microphone set DIP switch 2 to closedn.

General Information
After connecting intercom stations as described below, and before installing the
☞
mounting screws, connect a headset and perform the sidetone adjustment as described on page 10.
The WM1000 and WM2000 mount in a standard two-gang electrical box. Some example intercom system configurations are shown in Figures 2 through 5, pages 12
through 14. Detailed connections for the WM1000 and WM2000 are shown in Figures 6 and 7, pages 15 and 16. There are two basic methods for connecting the
WM1000 and WM2000: 1) using a phantom powered connection, and 2) using local
power. The two methods are discussed below:
Method 1: Phantom Powered Connection
In this method, operating power and intercom audio are delivered to the WM1000 /
WM2000 over the same wires. The advantage of this setup is simplicity of connection. Also, the Audiocom power supply automatically provides what is known as a
terminating impedance for the intercom system. Without this terminating impedance,
the sound quality on the channel will be very distorted, and the levels will shift every
time additional stations are connected to the channel. The disadvantage of the phantom power method is that some operating power is lost over very long intercom cables, and performance will then be reduced at remotely located stations. Generally, if
the intercom stations are located within a few hundred feet of the power supply,
phantom power will be sufficient. The actual distance over which power can be delivered can vary, however, depending on the number of stations connected. Increasing
the number of stations will reduce the distance. Note that the range over which power
can be delivered is independent from the range over which audio can be sent. Audio
can be transmitted for several miles, providing that intercom stations are locally powered as described below.
