Audiocom® Description The WM1000 and WM2000 Intercom Stations are designed for stationary, wallmounted 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 access 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.
Features 1. Channel Select Switch (WM2000 Only): Used to switch between intercom channels one and two. The switch lights green for channel one and red for channel two. 2. Intercom Listen Key: Both momentary (push-to-listen) and latching (hands-free listen) are possible. 3. Call Key: Used to send call signals on the intercom channel and to indicate incoming calls. 4. Intercom Talk Key: Both momentary (push-to-talk) and latching (hands-free talk) are possible.
Audiocom® Installation Unpacking Each WM1000 / WM2000 is supplied with the following items. Contact the shipper or your Audiocom dealer immediately if anything is damaged or missing. Detach and fill out the registration card and return it to Telex to properly register your intercom station.
Table 1.
Audiocom® 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.
Method 2: Locally Powered Connection Using this method, the intercom station is connected to the intercom line just like any phantom-powered intercom station, except that a local power supply is also connected. This local power supply is located right with the intercom station and provides power for that station only. Since power loss on the intercom lines is no longer an issue, the operating range is now limited only by the audio transmission range, which is several miles.
Audiocom® Power-Up Make sure any local power supplies are plugged in, and turn on the power switches of any phantom power supplies. ☞ If you are using a large number of locally powered intercom stations, you should activate their local power supplies before activating any phantom power supply. Otherwise, you may get an overload indication on the phantom supply. In this case, either reset the phantom supply, or momentarily turn it off, then on.
6. Install the intercom station mounting screws after completing the adjustments. The station is now ready for use. If you are using headphones that completely enclose the ears, adjust sidetone as follows: 1. Activate channel 1 as described in the operating instructions. (Required only for the WM2000, the WM1000 is active on whichever channel it is connected to.) 2. Activate talk and listen as described in the operating instructions. 3.
