Telex WM1000, WM2000 Specifications

WM-1000 and WM-2000

Wall Mount Intercom Systems

The WM-1000 and WM-2000 Intercom Stations are designed for stationary, wall mounted installation in standard two-gang elec­trical boxes. The WM-1000 is a single-channel station; the WM-2000 provides switch-selectable access to either of two intercom
channels. The WM-1000 and WM-2000 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. 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 telephone handset can be left at the station.
