“Instant Transmit Safety Switch” prevents accidental activation of functions that may cause negative consequences.
The safety switch can be used with Aux I/Os and pre-defined pages, as well as, instant transmit switches.
2.3.2.3 Audio Communication te the Field and Other Dispatch Operators
The dispatch operator can transmit audio in different ways. They can make calls to all users listening to a specific
conventional radio resource or a specific trunking talkgroup. When multiple resources are required, the dispatcher
can select additional talkgroups and/or conventional channels, as needed, using the multi-select feature. The MCC
7500 console also enables dispatch operators to make private calls to individual field radio users or dispatch
operators. Once a private call is established, it can be patched in with another resource at the dispatch operator's
discretion.
2.3.2.4 Controiling Console Audio
The MCC 7500 console offers dispatchers several different ways of controlling or muting the audio on their consoles:
2 Audio volume can be changed for any specific resource.
* Allnon-selected resources on the console can be muted for 30 seconds (“All Mute”) or unmuted, if already
muted.
° Adispatcher can transmit on a resource while receiving audio from the same resource or other resources.
* Adispatcher can mute the other dispatch audio on a shared resource to prevent acoustic feedback when a
co-located operator position transmits.
2.3.25 Cortrofling Hetwaork Audio
Dispatch operators can control the audio on the ASTRO 25 network. Using the console, the dispatcher can enable or
disable radio users in order to compartmentalize traffic, reduce interruptions, and maintain communications between
dispatch and the field. When this function is enabled or disabled, all dispatch consoles with this resource assigned
are updated with the current status of the feature.
Note: This feature can be controlled from any dispatch console.
2.3.3 Emergency Radic Transmission and Reception
As part of a mission-critical communications network, the MCC 7500 console will facilitate immediate prioritization
and resolution of emergency communications between The City's of Nashua and Manchester dispatch and first
responders in the field, enabling dispatch operators and first responders to focus on their mission, not their
equipment—especially during critical situations.
2.3.4.1 Receiving an Emergency Call
When a field user or another dispatch operator initiates an emergency call, the console emits both visual and audible
indications ("Emergency Alarm”). The audible indication alerts the dispatch operator that an emergency is
underway, the visual indication directs the dispatch operator's attention to the specific resource making the
emergency call. The dispatch operator can immediately reserve a voice channel for the duration of the emergency.
2.3.3.2 Responding to an Emergency Call
A dispatch operator can bypass the standard console interface to auto-open a quick list, which contains specific
controls for recognizing an emergency call, initiating an emergency call, and ending an emergency call (“Auto-Open
of Quick List”). The dispatcher can then “recognize” the emergency call, which ends the audible emergency
indication and notifies all dispatch operators that the emergency is being addressed (“Emergency Recognize”).
The audible emergency indication may also be muted by a dispatch operator without recognizing the emergency
alarm (“Mute Tones at a Single Op”). This would be used in a situation where one agency is monitoring a channel
that belongs to ancther agency. That channel can be configured to not generate audible and/or visual emergency
indications.
