6.29 EMERGENCY COMMUNICATIONS
The M7200 mobile radio can transmit both emergency voice calls and emergency alerts over the entire
network. OpenSky handles emergency calls and alerts with the highest priority.
For critical voice communications, an emergency call can be raised on the default talk group or the
currently selected talk group by “declaring” an emergency on the talk group. The exact talk group is
determined by the currently active profile. After successfully declaring an emergency on a talk group, the
declaring radio’s microphone remains “hot” for a predetermined amount of time. In other words, the radio
transmits audio for a period of time even when the microphone’s PTT button is not pressed. An
emergency talk group is provided greater priority and infinite hang-time by the radio system’s
infrastructure. Hang-time is the maximum duration of quiet time between transmissions on the talk group
before the infrastructure assets are automatically taken away. Because an emergency call is handled on a
talk group, it is received by all radios and consoles monitoring the talk group.
An emergency alert is a data message sent by the radio to the MIS console (or any console capable of
receiving it). It identifies the radio declaring the emergency, and the radio’s location (if the radio is
equipped with a GPS receiver). Voice audio is not automatically transmitted during the emergency if the
administrator configures the radio for alert notification only.
6.29.1 Declaring an Emergency Call or Alert
Press the red emergency button on the radio to enter emergency mode. The emergency is raised after the
emergency raise delay [default is one (1) second].
• If the active profile of the unit initiating the emergency is configured for Emergency Alert, the
emergency alert signal is sent to registered alert servers, such as the dispatcher console.
• If the active profile of the unit initiating the emergency is configured for Emergency Call, the
talkgroup is placed into emergency status notifying other radios and the emergency alert signal is sent
to the dispatcher console.
• If the emergency behavior of the active profile is Current, the active, selected voice group becomes
the default emergency voice group.
• If the emergency behavior of the active profile is Default, the radio moves to the default emergency
voice group of the profile and this talk group becomes the select talk group.
The display will alternate between the emergency voice group name and “EMERGENCY” and declaring
User ID to indicate that the emergency has been initiated.
