dispatch console while one or two headsets are connected, the desk microphone is only active during a transmit function when the dispatcher presses the transmit button on it. This solution prevents the desk microphone from picking up unwanted background sound when the dispatcher uses a headset to transmit. Each MCC 7500E Dispatch Console can support 1 desktop microphone. Desktop Speakers Two audio speakers have been included with each console position and can be configured to transmit audio from a specific talkgroup or set of talkgroups. Each speaker is a self-contained unit, with individual volume controls and can be placed on a desktop, or mounted on a rack or computer display. The MCC 7500E can support a maximum of 8 individual speakers per dispatch position. 1.3.7 AUXILIARY INPUTS AND OUTPUTS (NOT INCLUDED) An Auxiliary Input/Output server enables console operators to control and monitor external devices, such as doors and lights, from the console user interface. Multiple dispatch consoles anywhere in the network may monitor and control the same relay output and/or external inputs. Changes are indicated across all dispatch consoles simultaneously. Customizable graphic icons are also used to provide a visual indication of both the function and state of external inputs. The contact closures and input buffers required to interface to these devices are housed in Remote Terminal Units (RTUs). These RTUs can be physically located close to where they are needed, at any console site or network. Individual relay outputs can be configured so that they require a safety switch to be pressed before they respond to any commands from the dispatch console user. Supported Aux I/O Configurations The following Aux I/O configurations are supported. Aux I/O Configuration Description Momentary Input This is an input where the user interface always shows the true state of the input. Latched Input This is an input where the user interface does not necessarily show the true state of the input. When the input goes active, the user interface shows the state as active. The display will continue to show the state as active even if the input changes to the inactive state. A dispatch console user must manually reset the display to return it to the inactive state. Momentary Output This output relay is activated when the dispatch console user presses the button on the user interface and deactivated when the dispatch console user releases the button. This output relay changes state only when the dispatch console user Latched Output presses the button. This latched output relay is part of a group of latched output relays. Only Interlocked Latched Output one of the relays in the group may be active at a time. Interlocked relays he previously active relay is deactivated before the new relay is activated.
