Overview The U9921-GUV (40994G-01) Universal Gateway is a fixed-mounted wireless communication device that, when used in conjunction with one or more U9910-BSW (40992G-01), U9912-BSW (40992G-02), or U9913-BSW (40992G-07) Wireless Belt Stations, becomes part of a wireless intercom system. The U9921-GUV provides communication for up to four users as well as an interface to an existing wired intercom system. Up to four belt stations can be connected to one gateway.
Installation Intercom Interface The U9921-GUV is designed to add wireless capability to an existing wired intercom. Connection to the intercom is accomplished by connecting an interface cable to the interface connector of the U9921-GUV (see Figure 1). The following list contains David Clark intercom systems that have been tested to work with the U9921-GUV and the required cable assembly.

Range The range of a belt station and a gateway can be up to 300 ft (100m). If you are in an environment with metal or concrete walls, this range could be reduced. If the belt station enters into a "fringe" reception area, a brief sequence of three beeps will be heard in the headset. This is to serve as a warning of a possible disconnection if conditions are not improved. When possible, the user should attempt to regain line-of sight contact with the controller.
