The Alpha Communications RSM404 4-station master module provides LED annunciation (of 4 different colors) of the room status on an AlphaStatus room status system, for up to four (4) remote room locations. Virtually any number of RSM404 modules can be used to configure a system with the room station capacity needed. A momentary call pushbutton/switch is provided for optional signalling to each remote room location (requires additional components).

Each RSM404 module is designed to be mounted in the Alpha Communications/S.T.R. 'MT' series modular mounting frame, in Titanium (suffix- T), White (suffix-W) or Brown (suffix-B) color. The 'MT' frame can be mounted flush (in the wall), surface (on the wall) or desk mount, using the required flush or surface housing or sloped desktop adaptor.
